NOTE: Use a flexible hose between the pump and

any piping to eliminate any vibration in the piping.

3. Connect a hose from the air supply to the inlet air

port.

NOTE: Make sure that the air-control valve on the

diaphragm pump is closed before connecting to the

air supply.

CAUTION: Maximum air pressure is 100 PSI. Do not

exceed this rating.

NOTE: Due to the plastic construction of the pump, it

is recommended that for all hardware connections,

standard torque values should be used. Pipe-thread

sealant should be used on all plumbing connections.

Over torquing of any component can lead to

distortion of plastic.

OPERATION

WARNING: Wear safety glasses at all times when

operating the pump. Always wear a face shield and

proper body protection when working with hazardous

chemicals.

NOTE: Check for leaks before starting any pumping

operation. If any leaks or other abnormalities are

found, do not operate the pump.

1. The positive-displacement pump is self priming.

To initially prime the pump, using either the control

valve on the pump or the air-regulator valve, bring

the air pressure up slowly.

NOTE: Due to the fact that air and air mixed with

material (which may be a corrosive chemical) can

discharge quite violently during this procedure, direct

the discharge outlet back to the source at this time. If

a reel is used, bring the reel outlet back to the

source. If the reel is too far away for the hose to

reach, bleed the air into a separate container until the

pump and hose are primed.

NOTE: If starting difficulty is encountered, press the

reset button which is located at the air valve.

2. When the pump and hose are fully primed, the

pump is ready for operation.

NOTE: If the pump is operated faster than the

allowable flow rate, it can cause cavitation. This will

reduce the rate flow of the fluid and also reduces the

life of the diaphragm.

3. To obtain the maximum discharge rate, start the

pump by opening the ball valve gradually while

watching the discharging fluid until the flow rate

begins to diminish. Then close the valve slightly to

get the maximum discharge rate.

SERVICE

Trouble-Shooting:

For the most common of problems, a trouble-

shooting chart is provided as a guide to most of the

corrective remedies. (See Table 1.)

MAINTENANCE

INLET CHECK VALVES:

(Figures 3 and 6)

Disassembly:

NOTE: To remove the inlet check valves, the pump

must be turned over.

1. Remove the four nuts (4), lockwashers (3) and

flatwashers (2) that hold the two bases (40) and the

outlet manifold (13) to the two end castings (21).

2. Remove the two bases and the inlet manifold.

NOTE: There are two inlet cavities in the pump. This

procedure is written for one but is identical for the other.

3. Remove the top "O" ring (16) from the inlet cavity.

4. Remove the valve seat (23) from the inlet cavity.

5. Remove the valve cage (15) with the check-valve

disk from the inlet cavity.

6. Remove the check-valve disk (14) from the valve

cage.

7. Remove the bottom "O" ring (16) from the inlet cavity.

8. Clean and inspect all parts. Replace any parts that

are worn or show any signs of disintegration due to

the corrosive effects of some of the fluids.
