PRINCIPLE OF PUMP OPERATION

This ball type check valve pump is

powered by compressed air and is a 1:1

ratio  design.  The  inner  side  of  one

diaphragm  chamber  is  alternately

pressurized  while  simultaneously

exhausting the other inner chamber. This

causes  the  diaphragms,  which  are

connected by a common rod secured

by  plates  to  the  centers  of  the

diaphragms, to move in a reciprocating

action. (As one diaphragm performs the

discharge stroke the other diaphragm

is pulled to perform the suction stroke

in the opposite chamber.) Air pressure

is applied over the entire inner surface

of  the  diaphragm  while  liquid  is

discharged from the opposite side of the

diaphragm. The diaphragm operates in

a  balanced  condition  during  the

discharge stroke which allows the pump

to be operated at discharge heads over

200 feet (61 meters) of water.

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  to  maximize

diaphragm life.

Alternate  pressurizing  and

exhausting of the diaphragm chamber

is performed by an externally mounted,

pilot operated, four way spool type air

distribution valve. When the spool shifts

to  one  end  of  the  valve  body,  inlet

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 pressure to the chambers is

reversed. The air distribution valve spool

is moved by a internal pilot valve which

alternately pressurizes one end of the

air  distribution  valve  spool  while

exhausting the other end. The pilot valve

is shifted at each end of the diaphragm

stroke  when  a  actuator  plunger  is

contacted by the diaphragm plate. This

actuator plunger then pushes the end of

the  pilot  valve  spool  into  position  to

activate the air distribution valve.

The chambers are connected with

manifolds with a suction and discharge

check  valve  for  each  chamber,

maintaining flow in one direction through

the pump.

INSTALLATION AND START-UP

Locate  the  pump  as  close  to  the

product being pumped as possible. Keep

the suction line length and number of

fittings to a minimum. Do not reduce the

suction line diameter.

For installations of rigid piping, short

sections  of  flexible  hose  should  be

installed  between  the  pump  and  the

piping.  The  flexible  hose  reduces

vibration  and  strain  to  the  pumping

system.  A  surge  suppressor  is

recommended  to  further  reduce

pulsation in flow.

AIR SUPPLY

Air supply pressure cannot exceed

100 psi (7 bar). Connect the pump air

inlet to an air supply of sufficient capacity

and  pressure  required  for  desired

performance. When the air supply line

is  solid  piping,  use  a  short  length  of

flexible hose not less than ½" (13mm)

in diameter between the pump and the

piping to reduce strain to the piping. The

weight of the air supply line, regulators

and filters must be supported by some

means other than the air inlet cap. Failure

to provide support for the piping may

result in damage to the pump. A pressure

regulating valve should be installed to

insure  air  supply  pressure  does  not

exceed recommended limits.

AIR VALVE LUBRICATION

The air distribution valve and the pilot

valve are designed to operate WITHOUT

lubrication. This is the preferred mode of

operation. There may be instances of

personal preference or poor quality air

supplies  when  lubrication  of  the

compressed air supply is required. The

pump  air  system  will  operate  with

properly  lubricated  compressed  air

supply. Proper lubrication requires the

use of an air line lubricator (available from

Warren Rupp) set to deliver one drop of

SAE 10 non-detergent oil for every 20

SCFM (9.4 liters/sec.) of air the pump

consumes  at  the  point  of  operation.

Consult  the  pump’s  published

Performance Curve to determine this.

AIR LINE MOISTURE

Water in the compressed air supply

can create problems such as icing or

freezing of the exhaust air, causing the

pump  to  cycle  erratically  or  stop

operating. Water in the air supply can

be reduced by using a point-of-use air

dryer to supplement the user’s air drying

equipment. This device removes water

from  the  compressed  air  supply  and

alleviates the icing or freezing problems.

AIR INLET AND PRIMING

To start the pump, open the air valve

approximately  ½  to  ¾  turn.  After  the

pump primes, the air valve can be opened

to increase air flow as desired. If opening

the valve increases cycling rate, but does

not increase the rate of flow, cavitation

has occurred. The valve should be closed

slightly to obtain the most efficient air

flow to pump flow ratio.

BETWEEN USES

When the pump is used for materials

that tend to settle out or solidify when

not in motion, the pump should be flushed

after  each  use  to  prevent  damage.

(Product remaining in the pump between

uses could dry out or settle out. This

could  cause  problems  with  the

diaphragms and check valves at restart.)

In freezing temperatures the pump must

be completely drained between uses in

all cases.
