WARNING

To reduce the risk of serious injury, splashing in the eyes or on the skin, and toxic fluid spills, never move or lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the Pres-

sure Relief Procedure Warning on page 12 before moving or lifting the pump.

WARNING

A bleed-type master air valve (B) is required in your system to relieve air trapped between this valve and the pump. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury, including splashing in the eyes or on the skin, injury from moving parts, or contamination from hazardous fluids.

1.

Install the air line accessories as shown in Figs.

2 to 4 on pages 7 and 8. Mount these accessories on the wall or on a bracket. Be sure the air line supplying the accessories is grounded.

a.

Install an air regulator (C) and gauge to control the fluid pressure. The fluid outlet pressure at stall will be the same as the setting of the air regulator.

b.

Locate one bleed-type master air valve (B) close to the pump and use it to relieve trapped air. See the WARNING above. Locate the other master air valve (E) upstream from all air line accessories and use it to isolate them during cleaning and repair.

c.

The air line filter (F) removes harmful dirt and moisture from the compressed air supply.

2.

Install a grounded, flexible air hose (A) between the accessories and the 1/2 npt(f) pump air inlet

(N). See Fig. 5. Use a minimum 1/2” (13 mm) ID air hose. Screw an air line quick disconnect coupler (D) onto the end of the air hose (A), and screw the mating fitting into the pump air inlet snugly. Do not connect the coupler (D) to the fitting until you are ready to operate the pump.

Pressure Relief Valve

(Fuel Dispense Systems)

WARNING

Fuel Dispense Model 236267 requires a pressure relief valve 112353 (46), which is supplied with the pump, to prevent fluid pressure from exceeding 50 psi (350 kPa, 3.5 bar). Do not exceed the maximum air inlet pressure of 50 psi (350 kPa, 3.5 bar).

Recommended air operating pressure is 40 psi

(280 kPa, 2.8 bar) or less. As the air inlet pressure approaches 50 psi (350 kPa, 3.5 bar), the relief valve will open and vent fluid. Vented fluid must be routed to a container in a safe place.

03543B

Changing the Orientation of the Fluid Inlet and Outlet Ports

If desired, you can easily change the orientation of the fluid inlet and outlet ports. See Fig. 5.

1.

Remove the screws (6) holding the inlet and/or outlet manifold (1, 3) to the covers (2).

2.

Installation

Fluid Outlet Line Fluid Suction Line

1.

Use only electrically conductive fluid hoses.

The pump fluid inlet (3) is 1” npt(f). See Fig. 5.

Screw the fluid fitting into the pump inlet securely.

2.

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.

3.

At inlet fluid pressures greater than 15 psi (1.05

bar), diaphragm life will be shortened.

4.

See the Technical Data on pages 31 and 32 for maximum suction lift (wet and dry).

5.

For the Waste Oil Receiver Evacuation System, connect an appropriate suction hose (G) and fluid quick coupler (H) between the pump fluid inlet and the waste oil receiver (M). See Fig. 2.

6.

For the Gear Oil Evacuation System, install a control valve (R) and an appropriate wand (S). See

Fig. 3.

WARNING

A fluid drain valve (J) is required to relieve pressure in the hose if it is plugged. The drain valve reduces the risk of serious injury, including splashing in the eyes or on the skin, or contamination from hazardous fluids when relieving pressure. Install the valve close to the pump fluid outlet.

1.

Use only electrically conductive fluid hoses

(L). The pump fluid outlet (1) is 1” npt(f). See Fig.

5. Screw the fluid fitting into the pump outlet securely.

Air Exhaust Ventilation

Installation

WARNING

Be sure to read and follow the TOXIC FLUID

HAZARD and FIRE AND EXPLOSION HAZARD warnings on page 4 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 handling area, 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.

To provide a remote exhaust:

1.

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

2.

Install a grounded air exhaust hose (W) and connect the muffler (U) 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.

3.

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

See Fig. 6. Locate the container away from all sources of ignition, including pilot lights and waste materials. If the diaphragm ruptures, the fluid being pumped will exhaust with the air.

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

Fluid Pressure Relief Kit (for Pump Model

236265 only)

Pressure Relief Kit 238428 (Z) is available, to prevent overpressurization and rupture of the pump or hose. See Fig. 7. The kit includes instructions.

This kit is not for use in fuel dispense applica-

tions. Order a fuel dispense pump, Model 236267, which is equipped with a pressure relief valve

112353. See page 8.

CAUTION

Thermal expansion of fluid in the outlet line can cause overpressurization. This can occur when using long fluid lines exposed to sunlight or ambient 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.

Starting and Adjusting the Pump

All Systems

WARNING

To reduce the risk of serious injury, splashing in the eyes or on the skin, and toxic fluid spills, never move or lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the Pres-

sure Relief Procedure Warning on page 12 before moving or lifting the pump.

1.

Be sure the pump is properly grounded. Read and follow FIRE AND EXPLOSION HAZARD, on page

4.

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.

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

NOTE: 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.

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.

An air line lubricator is available, contact your Graco distributor for more information.

Flushing and Storage

WARNING

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

Pressure Relief Procedure on page 12.

Flush the pump often enough to prevent the fluid you are pumping from drying or freezing in the pump and damaging it. Always flush the pump and relieve the

pressure before storing it for any length of time. Use a compatible solvent.

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 29.

Preventive Maintenance Schedule

Establish a preventive maintenance schedule, based on the pump’s service history. This is especially important for prevention of spills or leakage due to diaphragm failure.
