Hytrel is a registered tradename of E.I. du Pont. Santoprene is a registered tradename of Exxon Mobil Corp.

Maximum and Minimum Temperatures are the limits for which
these materials can be operated. Temperatures coupled with
pressure affect the longevity of diaphragm pump components.
Maximum life should not be expected at the extreme limits of
the temperature ranges.

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.

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 hydrocarbons.

PRINCIPLE OF PUMP OPERATION

This ap swing 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 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 ow 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 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
completely 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 sufcient 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.

AIR INLET & PRIMING

For start-up, open an air valve approximately 1/2" to 3/4" turn. After the unit primes,

an air valve can be opened to increase ow as desired. If opening the valve increases
cycling rate, but does not increase ow rate, cavitation has occurred, and the valve

should be closed slightly.

For the most efcient use of compressed air and the longest diaphragm life, throttle
the air inlet to the lowest cycling rate that does not reduce ow.
