Materials
Nitrile General purpose, oil-resistant. Shows good solvent, oil, water and hydraulic uid resistance. Should
not be used with highly polar solvents
like acetone and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons.
EPDM Shows very good water and chemical resistance. Has poor resistance to oil and solvents, but is fair in
ketones and alcohols.
NEOPRENE All purpose. Resistant to vegetable oils. Generally not affected by moderate chemicals, fats,
greases and many oils and solvents. Generally
attacked by strong oxidizing acids, ketones, esters, nitro hydrocarbons and chlorinated aromatic hydrocar
bons.
®
Good on acids, bases, amines and glycols at room temperature.
HYTREL
PTFE Chemically inert, virtually impervious. Very few chemicals are known to react chemically with
PTFE: molten alkali metals, turbulent liquid or gaseous uorine and a few uoro-chemicals such as
chlorine triuoride or oxygen diuoride which readily liberate free uorine at elevated temperatures.
FKM (Fluorocarbon) shows good resistance to a wide range of oils and solvents; especially all aliphatic,
aromatic and halogenated hydrocarbons, acids, animal
and vegetable oils. Hot water or hot aqueous solutions (over 70°F) will attack FKM.

CF-8M Stainless Steel equal to or exceeding ASTM specication A743 for corrosion resistant iron chro-

to as 316 Stainless Steel in the pump industry.
Injection molded thermoplastic elastomer with no fabric layer. Long mechanical ex life. Excel-
Maximum and Minimum Temperatures are the limits for which
these materials can be operated. Temperatures coupled with

PLEASE NOTE!
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, disasembling or servicing
your pump.
PRINCIPLE OF PUMP OPERATION
This ball check valve pump is powered by compressed air and is a 1:1 pressure ratio
design. The pump is alternately pressurize through the inner side of one diaphragm
chamber, while simultaneously exhausting the other inner chamber. Air pressure
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, and the unit can be operated at discharge heads over
200 feet (61 meters) of water head.
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 air. 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 the pilot valve into
position for shifting of the air distribution valve.
The chambers are manifolded together with a suction and discharge check valve
for each chamber which maintains ow in one direction through the pump.
INSTALLATION & START-UP
Locate the pump as close to the product being pumped as possible. Keep suction
line length and number of ttings to a minimum. Do not reduce line size.
For installations of rigid piping, short exible sections of hose should be installed
between pump and piping. This reduces vibration and strain to the piping system.

This pump was tested at the factory prior to shipment and is ready for operation.
It is self-priming from a dry start for suction lifts of 20 feet (6.096 meters) or less. For
suction lifts exceeding 20 feet of liquid, ll the chambers with liquid prior to priming.

AIR SUPPLY
Air supply pressures cannot exceed 125 psi (8.61 bar). Connect the pump air inlet
to an air supply of sufcient capacity and pressure required for desired performance.
When the air line is solid piping, use a short length of exible hose [not less than
3/4" (19mm) in diameter] between pump and piping to eliminate strain to pipes.
