Safety Precautions

WARNING: READ THIS MANUAL COMPLETELY BEFORE INSTALLING AND OPERATING THIS UNIT. FAILURE TO FOLLOW THESE

PRECAUTIONS CAN RESULT IN SERIOUS INJURY OR DEATH.

WARNING: Magnetic field hazard. This pump contains powerful magnets. Exposed magnets (pump not connected to motor) produce powerful magnetic fields. Individuals with cardiac pacemakers, implanted defibrillators, other electronic medical devices, metallic prosthetic heart valves, internal wound clips (from surgery), metallic prosthetic devices or sickle cell anemia must not handle or be in the proximity of the magnets contained inside the pump. Consult a health care provider for specific recommendations before working with this pump.

WARNING: Magnetic force hazard. This pump should only be disassembled and assembled using the recommended procedures.

The magnetic attraction is powerful enough to rapidly pull the motor end and the wet end together. Do not place fingers between the mating surfaces of the motor and wet ends to avoid injuries. Keep the drive magnet and impeller assembly away from metal chips or particles, items with magnetic stripes like credit cards and magnetic computer media such as floppy discs and hard drives.

WARNING: Guidelines for pumping flammable or combustible liquids. Follow these guidelines when pumping flammable or combustible liquids with a DB Series pump:

1. You must use a PVDF pump. PVDF has conductive carbon fibers added which allow it to be grounded when installed in a prop- erly grounded piping system or when a properly installed grounding strap is attached to a housing bolt. If PVDF is not compatible with the liquid, you should then consider an ETFE lined UC Series mag-drive pump.

2. You must select the non-sparking (Ns) bronze bump ring option. The non-sparking ring is pressed into the clamp ring or motor adapter and prevents sparking should the motor bearingsfail and the outer mag drive assembly runs out of round.

3. Select and FTI explosion-proof motor or provide your own explosion-proof motor.

Follow these guidelines when pumping non-flammable or non-combustible liquids in a hazardous area with a DB Series pump:

1. You must select the non- sparking (Ns) bronze bump ring option. The non-sparking ring is pressed into the clamp ring or motor adapter and prevents sparking should the motor bearingsfail and the outer mag drive assembly runs out of round.

2. Select and FTI explosion-proof motor or provide your own explosion-proof motor.

WARNING: Hot surfaces. This pump is capable of handling liquids with temperatures as high as 220º F (104º C). This may cause the outer areas of the pump to become hot as well and could cause burns.

WARNING: Rotating Parts. This pump has components that rotate while in operation. Follow local safety standards for locking out the motor from the power supply during maintenance or service.

WARNING: Chemical Hazard. This pump is used for transferring many types of potentially dangerous chemicals. Always wear protective clothing, eye protection and follow standard safety procedures when handling corrosive or personally harmful materials.

Proper procedures should be followed for draining and decontaminating the pump before disassembly and inspection of the pump.

There may be small quantities of chemicals present during inspection.

could result in serious injury or damage to the pump and components.

CAUTION: This pump should never be started without liquid in the casing. If the pump has a PTFE, ceramic or silicon carbide bushing, IT CANNOT BE RUN DRY WITHOUT CAUSING DAMAGE TO THE PUMP. It is recommended that run dry protection be used.

Optional electronic power monitors are available to help protect against run dry. However, the pump can operate without liquid in the housing if the pump has a carbon bushing. The exact length of time the pump can operate dry with a carbon bushing varies with operating conditions and environment.

CAUTION: Never start or operate with a closed suction valve.

WARNING: Operation without priming or against a closed discharge valve can result in high temperatures that can result in injury or damage to pump components.

CAUTION: Always provide adequate NPSHa (net positive suction head available). It is recommended to provide at least 2 feet (61 cm) above the NPSHr (net positive suction head required).

CAUTION: If pump is used on variable speed drive, do not exceed the frequency for which the pump was designed (for example, if the pump is a 50 Hz model, do not exceed 50 Hz).

Safety Precautions for ATEX Pumps

CAUTION: Proper o-ring material must be chosen for the fluid being pumped. Improper material selection could lead to swelling and be a possible source of leaks. This is the responsibility of the end user.

WARNING: The pump must be checked for leaks on a regular basis. If leaks are noticed, the pump must be repaired or replaced immediately.

WARNING: The pump must be cleaned on a regular basis to avoid dust buildup greater than 5 mm.

WARNING: ATEX pumps must use a power monitor, flow switch, pressure switch or similar device to help protect against running dry, closed discharge valve and decoupling. Any of these conditions could lead to a rise in surface temperature of the pump.

8. Proceed to Installation Section

8

• Install the pump as close to the suction source as possible.

• Support the piping independently near the pump to eliminate any strain on the pump casing. In addition, the piping should be aligned to avoid placing stress on the pump casing.

• The suction side of the pump should be as straight and short as possible to minimize pipe friction.

• The suction line should not have any high spots. This can create air pockets that can reduce pump performance. The suction piping should be level or slope slightly upward to the pump.

• If flexible hose is preferred over pipe, use a reinforced hose rated for the proper temperature, pressure and is chemically resistant against the fluid being pumped.

• The suction valve must be completely open to avoid restricting the suction flow.

• When installing pumps with flanges, we recommend use of low seating stress gaskets such as Gore-Tex or Gylon

(expanded PTFE).

Motor/Electrical

Install the motor according to NEC requirements and local electrical codes. The motor should have an overload protection circuit.

Wire the motor for clockwise rotation when facing the fan end of the motor.

CAUTION: Do not operate the pump to check rotation until the pump is full of liquid.

Check all electrical connections with the wiring diagram on the motor. Make sure the voltage, frequency, phase and amp draw comply with the supply circuit.

To verify correct rotation of the motor:

1. Install the pump into the system.

2. Fully open the suction and discharge valves.

3. Allow fluid to flow into the pump. Do not allow the pump to run dry (ceramic, PTFE and silicon carbide bushings can’t be run dry without damage to pump components).

4. Jog the motor (allow it to run for 1-2 seconds) and observe the rotation of the motor fan. Refer to the directional arrow molded into the pump casing if necessary.

NOTE: A pump running backwards will pump but at a greatly reduced flow and pressure.

Section III - Start-up and Operation

Start-up and Operation

1. This pump must be filled from a flooded suction tank (gravity) or primed with liquid from an outside source. The DB22 is not self-priming.

2. Open the inlet (suction) and discharge valves completely and allow the pump to fill with liquid.

3. Close the discharge valve.

4. Turn the pump on. Slowly open the discharge valve. Adjust the flow rate and pressure by regulating the discharge valve. Do not attempt to adjust the flow with the suction valve.

Shutdown

1. Use the following procedure to shutdown the pump.

2. Slowly close the discharge valve.

3. Turn off the motor.

4. Close the suction valve.

Section IV - Maintenance

Recommended maintenance schedule

The recommended maintenance schedule depends upon the nature of the fluid being pumped and the specific application.

If the pump is used on a clean fluid, it is recommended that the pump be removed from service and examined after six months of operation or after 2,000 hours of operation. If the pump is used on fluids with solids, high temperatures or other items that could cause accelerated wear, then this initial examination should be sooner.

After the initial examination of the internal components and wear items are measured, a specific maintenance schedule can be determined. For best results, it is recommended that the pump be removed from service annually for examination.

Flush Systems

CAUTION: Some fluids react with water; use compatible flushing fluid.

1. Turn off the pump.

2. Completely close the suction and discharge valves

3. Connect flushing fluid supply to flush inlet valve.

4. Connect flushing fluid drain to flush drain valve.

5. Open flushing inlet and outlet valves. Flush system until the pump is clean.

Optional Drain Installation

1. Remove the impeller housing (item 1) from the pump assembly.

2. Clamp the impeller housing to a drill press table.

3. Using a 7/16” drill and the molded boss as a guide, drill completely through the molded boss into the interior of the impeller housing.

CAUTION: Do not tap too deep or the impeller housing may be damaged.

4. Using a ¼” NPT tap, tap the hole in the molded boss to the appropriate depth.

5. Install the drain plug or valve, being careful not to overtighten.

Troubleshooting

General Notes:

• Do not pump liquids containing ferrous metal fines.

• If magnets decouple, stop pump immediately. Operating the pump with the magnets decoupled will eventually weaken the magnets.

• Contact our Technical Service Department If you have any questions regarding product operation or repair:

Phone: 1-800-888-3743

E-mail: [email protected]

No or Insufficient Discharge

• Air leaks in suction piping

• Pump not primed

• System head higher than anticipated

• Closed valve

• Viscosity or specific gravity too high

• Motor too large for magnet coupling rating (magnets uncoupled)

• Suction lift too high or insufficient NPSH

• Clogged suction line or impeller vanes

• ·Motor rotation incorrect (correct rotation when viewed from the fan end is clockwise)

Insufficient Pressure

• Air or gas in liquid

• Impeller diameter too small

• System head lower than anticipated

• Motors speed insufficient (too low) or motor rotation incorrect (correct rotation when viewed from the fan end is clockwise)

Loss of Prime

• Leak in suction piping

• Foot valve or suction opening not submerged enough

• Foot valve too small or leaking

• Air or gas in liquid

• Foreign matter in impeller

• Leaking valve. Suction lift too high or insufficient NPSHa.

Excessive Power Consumption

• Head lower than rating

• Excessive flow

• Specific gravity or viscosity too high.

Vibration/Noise

• Loose magnet

• Drive magnet rubbing

• Pump cavitating from improper suction or feed

• Motor or piping not properly secured

• Foreign object in impeller
