PLEASE NOTE!

The photos 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 OPERATION

This ball 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 re-

versed. 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 valve spool. This pushes

it into position for shifting of the air distribution valve.

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

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 10 feet (3.05 meters) or less.

For suction lifts exceeding 10 feet of liquid, fill the chambers with liquid prior to priming.

AIR SUPPLY

Air supply pressures cannot exceed 100 psi (6.89 bar). Connect the pump air inlet

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 ¾"

(19mm) in diameter) between pump and piping to eliminate strain to pipes.

AIR INLET & PRIMING

For start-up, open an air valve approximately ½ to ¾ turn. After the unit primes,

an air valve can be opened to increase flow as desired. If opening the valve

increases cycling rate, but does not increase flow rate, cavitation has occurred, and

the valve should be closed slightly.

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.

WARNING

Take action to prevent static sparking.

Fire or explosion can result, especially

when handling flammable liquids. The

pump, piping, valves, containers or

other miscellaneous equipment must be

grounded.

BEFORE OPERATION

Before pump operation, inspect all

gasketed fasteners for looseness

caused by gasket creep. Retorque loose

fasteners to prevent leakage. Follow

recommended torques stated in this

manual

DANGER

Before doing any maintenance on the

pump, be certain all pressure is

completely vented from the pump,

suction, discharge, piping, and all other

openings 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 all

times in the vicinity of the pump. Failure

to follow these recommendations may

result in serious injury or death.

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.
