Fluid Pressure Relief Valve Changing the Orientation of the Fluid Inlet and Outlet Ports

The pump is shipped with the fluid inlet (R) and outlet

(S) ports facing the same direction. See Fig. 4. To change the orientation of the inlet and/or outlet port:

1.

Remove the screws and washers (106, 112, 113 and 114) holding the inlet (102) and/or outlet (103) manifold to the covers (101).

2.

Reverse the manifold and reattach. Install the screws and washers and torque to 150- 160 in- lb

(17- 18 N•m). See

Torque Sequence

, page 33.

CAUTION

Some systems may require installation of a pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose. See Fig. 5.

Thermal expansion of fluid in the outlet line can cause overpressurization. This can occur when using long fluid lines exposed to sunlight or ambi- ent heat, or when pumping from a cool to a warm area (for example, from an underground tank).

Overpressurization can also occur if the Husky pump is being used to feed fluid to a piston pump, and the intake valve of the piston pump does not close, causing fluid to back up in the outlet line

WARNING

FIRE AND EXPLOSION HAZARD

Be sure to read and follow the warnings and precautions regarding T

OXIC FLUID

HAZARD,

and

FIRE OR EXPLOSION

HAZARD

on page 5, before operating

this pump.

Be sure the system is properly ventilated for your type of installation. You must vent the exhaust to a safe place, away from people, animals, food handl- ing areas, and all sources of ignition when pumping flammable or hazardous fluids.

Diaphragm failure will cause the fluid being pumped to exhaust with the air. Place an appropriate container at the end of the air exhaust line to catch the fluid. See Fig. 6.

The air exhaust port is 3/4 npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation.

If the muffler (P) is installed directly to the air exhaust port, apply PTFE thread tape or anti- seize thread lubricant to the muffler threads before assembly.

To provide a remote exhaust:

1.

Remove the muffler (P) from the pump air exhaust port.

2.

Install an electrically conductive air exhaust hose (T) and connect the muffler (P) to the other end of the hose. The minimum size for the air exhaust hose is

3/4 in. (19 mm) ID. If a hose longer than 15 ft

(4.57 m) is required, use a larger diameter hose.

Avoid sharp bends or kinks in the hose. See Fig. 6.

3.

Place a container (U) at the end of the air exhaust line to catch fluid in case a diaphragm ruptures.

Operation

Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The equipment stays pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the gun or splashing fluid, follow this procedure whenever you:

• Are instructed to relieve pressure,

• Stop pumping,

• Check, clean or service any system equipment,

• Install or clean fluid nozzles.

1.

Shut off the air to the pump.

2.

Open the dispensing valve, if used.

3.

Open the fluid drain valve to relieve all fluid pressure, having a container ready to catch the drainage.

Flush the Pump Before First Use

The pump was tested in water. If water could contaminate the fluid you are pumping, flush the pump thoroughly with a compatible solvent. Follow the steps under

Starting and Adjusting the Pump

.

Starting and Adjusting the Pump

WARNING

TOXIC FLUID HAZARD

Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed. Do not lift a pump under pressure. If dropped, the fluid section may rupture. Always fol- low the

Pressure Relief Procedure

above before lifting the pump.

1.

Be sure the pump is properly grounded. Refer to

Grounding

on page 7.

2.

Check all fittings to be sure they are tight. Be sure to use a compatible liquid thread sealant on all male threads. Tighten the fluid inlet and outlet fittings securely.

3.

Place the suction tube (if used) in the fluid to be pumped.

NOTE:

If the fluid inlet pressure to the pump is more than 25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in inefficient pump operation.

4.

Place the end of the fluid hose (L) into an appropriate container.

5.

Close the fluid drain valve (J). See Fig. 2.

6.

With the pump air regulator (C) closed, open all bleed-type master air valves (B, E).

7.

If the fluid hose has a dispensing device, hold it open while continuing with the following step.

8.

Slowly open the air regulator (C) until the pump starts to cycle. Allow the pump to cycle slowly until all air is pushed out of the lines and the pump is primed.

If you are flushing

, run the pump long enough to thoroughly clean the pump and hoses. Close the air regulator. Remove the suction tube from the solvent and place it in the fluid to be pumped.

308550 13

Operation

Operation of Remote Piloted Pumps

1.

Fig. 2 and Parts Drawings. Follow preceding steps 1 through 7 of

Starting and Adjusting Pump

.

2.

Open air regulator (C).

NOTE:

Leaving air pressure applied to the air motor for extended periods when the pump is not running may shorten the diaphragm life. Using a 3- way solenoid valve to automatically relieve the pressure on the air motor when the metering cycle is complete prevents this from occurring.

Pump Shutdown

WARNING

The pump may cycle once before the external signal is applied. Injury is possible. If pump cycles, wait until end before proceeding.

3.

Pump will operate when air pressure is alternately applied and relieved to push type connectors (14).

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure

at left.

At the end of the work shift, relieve the pressure.

Maintenance

Lubrication

The air valve is designed to operate unlubricated.

However, if lubrication is desired, every 500 hours of operation (or monthly) remove the hose from the pump air inlet and add two drops of machine oil to the air inlet.

CAUTION

Do not over-lubricate the pump. Oil is exhausted through the muffler, which could contaminate your fluid supply or other equipment. Excessive lubrication can also cause the pump to malfunction.

Flush the pump often enough to prevent the fluid you are pumping from drying or freezing in the pump and damaging it. Flush with a fluid that is compatible with the fluid you are pumping and with the wetted parts in your system. Check with your fluid manufacturer or supplier for recommended flushing fluids and flushing frequency.

Always flush the pump and relieve the pressure before storing it for any length of time.

Tightening Threaded Connections

Before each use, check all hoses for wear or damage, and replace as necessary. Check to be sure all threaded connections are tight and leak free. Check fasteners.

Tighten or retorque as necessary. Although pump use varies, a general guideline is to retorque fasteners every two months. See

Torque Sequence

, page 33.

Flushing and Storage

Reassembly - Standard Diaphragms

1.

Grease the shaft u-cup packings (402*) and install them so the lips face out of the housing (1). See

Fig. 13.

2.

Grease the length and ends of the diaphragm shaft

(24) and slide it through the housing (1).

3.

Assemble the inner diaphragm plates (104), diaphragms (401*), PTFE diaphragms (403*, if present), and outer diaphragm plates (105) exactly as shown in Fig. 13. These parts

must

be assembled correctly.

4.

Apply medium-strength (blue) Loctite

®

or equivalent to the threads of the fluid-side plates (105). Hold one of the outer plates (105) with a wrench, and torque the other outer plate to 20 to 25 ft-lb (27 to

34 N•m) at 100 rpm maximum.

Do not over-torque

.

Reassembly - Overmolded Diaphragms

WARNING

To reduce the risk of serious injury, including amputation, do not put your fingers or hand between the air cover and the diaphragm.

1.

Lubricate and install the shaft u- cup packings

(402*) so the lips face

out

of the housing (1).

See Fig. 13.

2.

Assemble the air side plate (104) onto the diaphragm (403). The wide, radiused side of the plate must face the diaphragm. Apply medium- strength (blue) Loctite or equivalent to the threads of the diaphragm assembly. Screw the assembly into the shaft (24) hand- tight.

3.

Grease the length and ends of the diaphragm shaft

(24). Insert the shaft/diaphragm assembly into one side of the pump. Align the fluid cover (101) and the center housing (1) so the arrow (A) faces the same direction as the air valve. Secure the cover with the screws (107 and 108), handtight.

4.

Torque the longer screws (108) oppositely and evenly to 190- 220 in- lb (21- 25 N•m), using a

13mm socket wrench. Then torque the shorter screws (107). See

Torque Sequence

, page 33.

5.

Assemble the other diaphragm assembly to the shaft as explained in step 2. This diaphragm will be lifted off the air cover at this point.

6.

Supply the pump with low pressure air (less than

7 psi [0.05 MPa, 0.5 bar]). The diaphragm will very slowly pull onto the air cover. Find the pressure that keeps the diaphragm close enough to secure with the screws, but does not let it contact the pilot pin.

NOTE:

Do not deform the diaphragm manually. The diaphragm needs uniform pressure to deform properly for maximum life.

7.

Align the fluid cover (101) and the center housing

(1) so the arrow (A) faces the same direction as the air valve. Secure the cover with two of the longer screws (108), handtight.

NOTE:

If the diaphragm contacts the pilot pin and is forced away from the air cover, try Step 5 again. If necessary, return to Step 3.

8.

Torque the longer screws (108) oppositely and evenly to 190- 220 in- lb (21- 25 N•m), using a

13mm socket wrench. Then torque the shorter screws (107). See
