IMPORTANT

Read these instructions completely,

before installation and start-up. It is the

responsibility of the purchaser to retain

this manual for reference. Failure to

comply with the recommendations

stated in this manual will damage the

pump, and void factory warranty.

HAZARD WARNING

POSSIBLE EXPLOSION HAZARD can

result if 1, 1, 1,-Trichloroethane,

Methylene Chloride or other

Halogenated Hydrocarbon solvents are

used in pressurized fluid systems

having Aluminum or Galvanized wetted

parts. Death, serious bodily injury and/

or property damage could result.

Consult with the factory if you have

questions concerning Halogenated

Hydrocarbon solvents.

DANGER

Before doing any maintenance on the

pump, be certain all pressure is com-

pletely vented from the pump, suction,

discharge, piping, and all other open-

ings and connections. Be certain the air

supply is locked out or made non-

operational, so that it cannot be started

while work is being done on the pump.

Be certain that approved eye protection

and protective clothing are worn at all

times in the vicinity of the pump. Failure

to follow these recommendations may

result in serious injury or death.

The photos shown in this manual are for general instruction only. YOUR SPECIFIC

MODEL MAY NOT BE SHOWN. Always refer to the parts list and exploded view

drawing for your specific model when installing, disassembling or servicing your

pump.

PRINCIPLE OF PUMP OPERATION

This ball type check valve pump is powered by compressed air and is a 1:1

pressure ratio design. It alternately pressurizes the inner side of one diaphragm

chamber, while simultaneously exhausting the other inner chamber. This causes the

diaphragms, which are connected by a common rod, to move endwise. Air pressure

is applied over the entire surface of the diaphragm, while liquid is discharged from the

opposite side. The diaphragm operates under a balanced condition during the

discharge stroke, which allows the unit to be operated at discharge heads over 200

feet (61 meters) of water head.

Since the diaphragms are connected by a common rod, secured by plates to the

center of the diaphragms, one diaphragm performs the discharge stroke, while the

other is pulled to perform the suction stroke in the opposite chamber.

For maximum diaphragm life, keep the pump as close to the liquid being pumped

as possible. Positive suction head in excess of 10 feet of liquid (3.048 meters) may

require a back pressure regulating device. This will maximize diaphragm life.

Alternate pressuring and exhausting of the diaphragm chamber is performed by

means of an externally mounted, pilot operated, four-way spool type air distribution

valve. When the spool shifts to one end of the valve body, inlet air pressure is applied

to one diaphragm chamber and the other diaphragm chamber exhausts. When the

spool shifts to the opposite end of the valve body, the porting of chambers is reversed.

The air distribution valve spool is moved by an internal pilot valve which alternately

pressurizes one side of the air distribution valve spool, while exhausting the other side.

The pilot valve is shifted at each end of the diaphragm stroke by the diaphragm plate

coming in contact with the end of the pilot spool. This pushes it into position for shifting

of the air distribution valve.

The chambers are manifolded together with a suction and discharge check valves

for each chamber, maintaining flow in one direction through the pump.

INSTALLATION & START-UP

Locate the pump as close to the product being pumped as possible, keeping

suction line length and number of fittings to a minimum. Do not reduce line size.

For installations of rigid piping, short flexible sections of hose should be installed

between pump and piping. This reduces vibration and strain to the piping system. A

Warren Rupp Tranquilizer

surge suppressor is recommended to further reduce

pulsation in flow.

This pump was tested at the factory prior to shipment and is ready for operation.

It is completely self-priming from a dry start for suction lifts of 15 feet (4.5 meters) or

less. For suction lifts exceeding 15 feet of liquid, fill the chambers with liquid prior to

priming.

AIR SUPPLY

Air supply pressures cannot exceed 100 psi (7.0 bar). Connect the pump air inlet

(Fig. 1) to an air supply of sufficient capacity and pressure required for desired

performance. When the air line is solid piping, use a short length of flexible hose not

less than

/2" (12.7mm) in diameter between pump and piping to eliminate strain to

pipes. The weight of the air supply line and of the filter must be supported by some

means other than the air valve cap. Failure to provide support may result in damage

to the pump. A pressure regulating valve should be installed to prevent pressure from

exceeding recommended limits.
