Care of Stainless Steel

The stainless steel components in Dixon Sanitary equipment are machined, welded and assembled by skilled craftsmen using manufacturing methods that preserve the corrosion-resistant quality of the stainless steel.

Retention of corrosion-resistant qualities under processing conditions requires regular attention to the precautions listed below.

1.

Regularly check all electrical devices connected to the equipment for stray currents caused by improper grounding, damaged insulation or other defects. Corrosion: Pitting often occurs when stray currents come in contact with moist stainless steel.

2.

Never leave rubber mats, fittings, wrenches, etc. in contact with stainless steel. Corrosion: Pitting or galvanic action. Objects retard complete drying, preventing air from reforming the protective oxide film. Galvanic corrosion occurs when two dissimilar metals touch when wet.

3.

Immediately rinse equipment after use with warm water until the rinse water is clear. Clean the equipment (manual or CIP) as soon as possible after rinsing. Corrosion: discoloration, deposits, pitting. Product deposits often cause pitting beneath the particles.

4.

Use only recommended cleaning compounds. Purchase chemicals from reputable and responsible chemical manufacturers familiar with stainless steel processing equipment, they continuously check the effects of their products on stainless steel.

5.

Use cleaning chemicals exactly as specified by the manufacturer. Do not use excessive concentrations, temperatures or exposure times. Corrosion: Pitting, discoloration, stress cracks. Permanent damage often occurs from excessive chemical concentrations, temperatures or exposure times.

6.

For manual cleaning, use only soft non-metallic brushes, sponges or pads. Brush with the grain on polished surfaces, avoid scratching the surface. Corrosion: Pitting, scratches. Metal brushes or sponges will scratch the surface and promote corrosion over a period of time. Metal particles allowed to remain on a stainless steel surface will cause pitting.

7.

Use chemical bactericides exactly as prescribed by the chemical manufacturer in concurrence with local health authority. Use the lowest permissible concentration, temperature and exposure time possible. Flush immediately after bacterial treatment. In no case should the solution be in contact with stainless steel more then 20 minutes. Corrosion: Protective film destroyed. Chlorine and other halogen bactericides can destroy the protective film. A few degrees increase in temperature greatly increases chemical activity and accelerates corrosion.

8.

Regularly inspect the joints in pipelines. Be sure all connections are tight fitting without binding. Corrosion: Crevice corrosion.

Small crevices caused by improperly seated gaskets will promote crevice corrosion. Stainless steel under stress will develop stress cracking especially in the presence of bactericides containing chlorine.

9.

Regularly inspect equipment for surface corrosion (i.e. pitting deposits, stress cracks, etc.). If deposit or color corrosion is detected, remove it immediately using mild scouring powder and detergents. Rinse thoroughly and allow to air dry. Review production and cleaning procedures to determine the cause. Note: If corrosion is not removed, the protective film cannot be restored and corrosion will continue at an accelerated rate.

Unpacking

Carefully unpack all parts of the pump and inspect for damage that may have occurred during shipment. Report any damages to the carrier immediately.

The ports on the pump are protected with a plastic cover. If any covers are missing or damaged, inspect the ports on the pump thoroughly for any damage.

If you are receiving a complete base mounted unit, please check shaft alignment as it may have changed during shipment.

The drawing below shows how the pump should be lifted. Ensure that the lifting equipment is correctly rated.

10 800.789.1718


Installation & Start Up

Mounting Configurations

Pump Mounting Adjustable:

• Adjustable leg base, commonly used for sanitary pumps for wash down under base. Can be easily moved or repositioned.

Pump Mounting Casters:

• Portable bases – for movement to different locations. Can also be mounted on a cart with handles.


11


Proper Installation

Piping Support :

Weight of piping and fluid – support piping independently with hangers or pedestals. On rectangular inlet flange pumps, hopper should also be supported independently.

12 800.789.1718



Proper Installation (continued)

Piping Slope:

• Inlet side – slope piping up to inlet to avoid air pocket.


13



Pressure Gauges:

Pressure and vacuum gauges provide the easiest way to tell you something about the pump operation.

• Normal or abnormal pressures

• Overflow conditions

• Indication of flow

• Changes in pump condition

• Changes in system conditions

• Changes in fluid viscosity

14 800.789.1718




Inlet Check Valve:

• Inlet side – use check valves to keep inlet line full, particularly with low viscosity fluids, and in start-stop operation.

Outlet Check Valve:

• Inlet Vacuum Service – use check valve on outlet side.

• Prevents backflow (air or fluid)

• Facilitates initial start-up (minimizes differential pressure pump must supply to start flow)


15



Thermal Expansion:

Thermal expansion of piping can cause tremendous forces. Use thermal expansion joints to minimize forces on pump. Flexible joints can also be used to limit the transmission of mechanical vibration. Anchor free ends of any flexible hose in system.

Isolation Valves:

• Isolation Valves – permit pump maintenance and removal safely without emptying entire system.

16 800.789.1718




Relief Loop:

Relief Valve – To protect the pump and piping system against excessive pressure, a relief valve should be installed. An integral relief valve, designed to bypass the fluid internally from the pump outlet to the inlet, should not be used on applications where the discharge must be closed for more than a few minutes. Prolonged operation of the pump with closed discharge with cause heating of the fluid circulating through the relief valve.


17


At Start Up

Pump Flow:

All pumps are labeled with flow direction based on motor being wired for clockwise rotation. If motor is wired for counterclockwise rotation, flow direction will be opposite of what is indicated on pump head.

18 800.789.1718



At Start Up

Pump Alignment:

A flexible coupling is used to compensate for end play and small differences in alignment. The pump and drive shaft should be aligned as closely as possible.

• Check angular alignment using feeler or taper gauge.

Adjust to get equal dimension at all points – at the same time, set space between coupling halves to the coupling manufacturer’s recommended distance.

• Note: Pump is aligned prior to shipping, after installation verify alignment as misalignment may have occurred during shipment.


19

Maintenance

Pump Housing Disassembly - Single Mechanical Seal

Prior to removal of pump, the shut-off valves in the suction and discharge lines must be closed. If there is any risk that product may harden, crystallize or freeze in the pump it should be thoroughly drained and cleaned immediately after use. Same attention applies if there is a seal flush option. Power needs to be locked out to prevent unintended start of the pump.

Note: Reference numbers are listed in the sectional view located on pages 61-73.

Maintenance

Rotor Clearance

Use feeler gauges to verify the back and radial clearances between the rotors and the housing. A depth gauge should be used to verify the front clearance.

Rotor clearance must be precisely maintained to provide maximum pumping efficiency, prevent contact between rotors, rotor housing and front cover during operation. If pumping efficiency is below expectations or if parts contact has occurred during operation (within rated differential pressure) check rotor clearances and adjust if incorrect.

Maintenance

Rotor Clearance (continued)

Rotor width and body depth are fixed at manufacturer. Therefore, with the correct rotor size selected, the only maintenance adjustment that can be made is the proportion of front and rear clearance. Measure the front clearance as follows:

1.

The rotor to rotor housing back face clearance is maintained by the shim (45).

2.

Check that the rotor housing (31) is tight to gearbox (1A). And check the rotor bolts (35) are tight.

3.

Measure the clearance between the back face of the pump housing and the back of the rotor with a feeler gauge. Check the reading with the recommended back face clearance.

54 800.789.1718

Rotor Clearance (continued)

4.

If incorrect, adjust by adding or removing shim plates (45) from behind the pump housing.

5.

Check each rotor and adjust as necessary.


55

Maintenance

Rotor Timing

Rotor timing must be precisely maintained to provide maximum pumping efficiency, prevent contact between rotors during operation.

If pumping efficiency is below expectations or if rotors contact during operation (within rated differential pressure), check rotor timing and adjust if incorrect. Also check rotor timing after any gearbox dismantling when the gears are removed and/or replaced.

Check Rotor timing as follows:

1.

Assemble each rotor in its normal location on the drive shaft and the idle shaft. Assemble each rotor bolt and tighten hand tight.

2.

Rotate the shafts 30 degrees and measure gap as illustrated by arrows. Rotate the shafts 60 degrees the opposite direction and measure gap as illustrated.

3.

The rotors are correctly timed when the gap measured, using a feeler gauge, at both locations are equal. If the gap is unequal, adjust the timing as follows.

4.

Rotor timing is determined by the relative location of the two helical gears (14) on the shafts. Gear spacers (16) are used to adjust the location and the timing. When adjusting timing, move only one of the two gears.

5.

Place the wooden dowel between the rotors.

6.

Bend away the tab of the lock washer (12) on one shaft. Loosen the lock nut and temporarily insert shim stock between the gear and gear spacer. Tighten the lock nut, reassemble the rotor in its correct location, and recheck rotor timing.

• If rotor timing is correct, remove the gear and replace added other spacer or add a shim equal in thickness to the shim stock temporarily added. Reassemble the gear and gear nut, tighten to the correct torque, and check rotor timing again to confirm that it is correct.

• If rotor timing is incorrect, but closer to equal than original measurement, repeat previous step adding additional shim stock.

• If rotor timing is incorrect and more unequal than original measurement, remove temporary shim stock from one shaft and add instead to the other shaft.

7.

Repeat above procedures until the timing gap is equal after gear spacers are in place and gear nuts are tightened to correct torque.

No Flow, Pump Not Priming

Insufficient Flow

Insufficient Flow – Flow Being

Bypassed Somewhere

Relief valve not properly adjusted or held open by foreign material.

Suction port is blocked, not allowing flow to the pump.

Valve closed in inlet line.

Inlet line clogged or restricted.

Air leaks due to bad gaskets or pipe connections.

Pump speed too slow.

Pump speed to fast for high viscosity liquid.

Liquid drains or siphons from system during off periods.

"Air" lock caused by fluids which "gas off" or vaporize or allow gas to come out of material during off periods.

Extra clearance rotors, worn pump.

NPSHA too low.

Adjust or clear valve.

Check all inlet valves, strainers and tank outlet ports.

Open valve.

Clear line, clean filters, etc.

Replace gaskets, check lines for leakage (can be done by air pressure or by filing with liquid and pressurizing with air.

Increase pump speed.

Decrease pump speed.

Use foot valve or check valves. Filling inlet lines with material before startup may solve startup priming problems due to no material in system.

Install and use a manual or automatic air bleed from pump or lines near pump.

Increase pump speed within limits, use foot valve to improve priming.

Replace worn rotors.

Check net inlet pressure available against net inlet pressure required. Change inlet system as needed.

Install check valve in discharge line.

On "Vacuum" inlet system: On initial start-up, atmospheric "blow back" prevents pump from developing enough differential pressure to start flow.

Speed too low or too high to obtain desired flow.

Air leak due to bad seals, pipe connections or other equipment.

Flow diverted in branch line, open valve, etc.

Check curve and adjust as necessary.

Replace seals, check inlet fittings.

Check system and controls.

Insufficient Flow – High Slip

Relief valve not adjusted or jammed.

Hot (HC) or extra clearance rotors being used on "cold" fluid and/or low viscosity fluid.

Worn pump.

Clear or adjust valve.

Replace with standard clearance rotors.


High pressure.

Troubleshooting

Possible Cause

Strainers, foot valves, inlet fittings or lines clogged.

Inlet line size too small, inlet line too long. Too many fittings or valves. Foot valve, strainers too small.

NPSHA too low.

Fluid viscosity greater than expected.

Fluid temperature higher than expected (vapor pressure higher).


Clear lines. If problem continues, inlet system may require changing.

Increase inlet line size. Reduce length, minimize direction and size changes, reduce number of fittings.

Raise liquid level in source tank to increase net inlet pressure.

Increase net inlet pressure by raising or pressurizing source tank.

Select larger pump size with lower net inlet pressure required.

Reduce pump speed and accept lower flow or change system to reduce line losses.

Change temperature of product to reduce viscosity.

Reduce temperature, reduce speed and accept lower flow or change system to increase net inlet pressure available.

Cavitation

High fluid viscosity

High vapor pressure fluid

High temperature.

Slow down pump, reduce temperature, change system setup.

NPSHA less than NPSHR.

Air or gas in fluid .

Leaks in the pump or piping.

Increase NPSHA or decrease NPSHR.

Fix leaks.

Dissolved gas or naturally aerated products.

Minimize discharge pressure (also see

"Cavitation" above).

Rotor to Body Contact

Improper assembly of pump.

Distortion of pump due to improper piping installation.

Check clearances and adjust shimming.

Change piping installation to eliminate piping stress and distortion on body.

Reduce discharge pressure required.

Pressures required higher than the pump is rated for.

Worn bearings.

Rebuild with new bearings and lubricate regularly.

Rotor to Rotor Contact

Loose or incorrectly-timed gears.

Sheared keys.

Worn gear splines.

Drive noise caused by gear trains, chains, couplings or bearings.

Rebuild with new parts. Note: This will cause severe damage.



Repair or replace drive parts. Check bearings for damage and replace as necessary.

800.789.1718


Troubleshooting

Problem

Pump Requires Excessive

Power (overheats, stalls, high current draw, breakers trip)

Possible Cause

Higher than expected viscosity losses.

Higher than expected pressures.

Fluid is colder with a higher viscosity than expected.

Fluid sets in line and pump during shutdown.

Short Pump Service Life

Any Other Issue

Fluid builds up on pump surfaces.

Pumping abrasives.

Speeds and pressures higher than rated.

Worn bearings and gears due to lack of lubrication.

Misalignment of drive and piping. (Excessive overhung load or misaligned couplings.)


If within pump rating, increase drive size

Reduce pump speed. Increase line sizes.

Heat fluid, insulate lines or heat trace lines.

Increase line sizes.

Insulate lines or heat trace lines.

Install a "soft start" drive.

Install a recirculating bypass system.

Flush system with a nonsetting fluid.

Replace the pump with more running clearances.

Larger pumps at slower speeds.

Reduce speeds and pressures by making changes in the system.

Replace pump with a larger model with higher pressure ratings.

Check and replace bearing and gears as necessary. Adjust lubrications schedule to decrease time between lubrication.

Modify external wash down method to reduce water entering into gear case.

Check alignment of piping and drive. Adjust as necessary.
