WARNING: Always wear safety glasses when operating

a pump to avoid eye injury. If diaphragm rupture occurs,

material being pumped may be forced out of the air

exhaust.

CAUTION: Do not apply compressed air to the exhaust

port –pump will not function.

CAUTION: Do not over-lubricate air supply–excess

lubrication will reduce pump performance. Pump is pre-

lubed.

NOTE: Not all materials are available for all models. See “Wilden

Pump Designation System”for material options for your pump.

CAUTION: When choosing pump materials, be sure to

check the temperature limits for all wetted components.

Example: FKM has a maximum limit of 177° C (350° F),

but polypropylene has a maximum limit of only 79° C

(175° F).

CAUTION: Pump surfaces may exceed 80° C (176° F),

contact will result in burns, scalds, and other injuries.

Surface temperature is dependent on the temperature of

the process fluid.

CAUTION: Maximum temperature limits are based on

mechanical stress only. Certain chemicals will reduce

maximum safe operating temperatures significantly.

Consult the Chemical Resistance Guide for chemical

compatibility and temperature limits.

CAUTION: All Wilden pumps are capable of passing

solids. Use a strainer on the pump intake to ensure that

the pump's rated solids capacity is not exceeded.

CAUTION: Do not exceed 8.6 bar (125 psig) air supply

pressure.

CAUTION: Do not exceed 82° C (180° F) air inlet

temperature for all models.

CAUTION: The process fluid and cleaning fluids must be

compatible chemically with all wetted pump components.

CAUTION: Before attempting any maintenance or repair,

disconnect the compressed air line to the pump and allow

all air pressure to bleed from the pump. Disconnect all

intake, discharge, and air lines. Drain the pump by turning

it upside down and allowing any fluid to flow into a

suitable container. Be aware of any hazardous effects of

contact with your process fluid.

CAUTION: Thoroughly flush pumps before installing

them into process lines. Clean and/or sanitize FDA- and

USDA- approved pumps before using them.

CAUTION: Before attaching the air line to the pump, blow

out the air line for 10 to 20 seconds to make sure all

pipeline debris is clear. Use an in-line air filter. A 5µ

(micron) air filter is recommended.

CAUTION: Pro-Flo R pumps can be used in submersible

applications when using the Pro-Flo R submersible

option.

CAUTION: Before installation, tighten all hardware.

NOTE: Materials of construction and elastomer material

may influence suction lift parameters. Please refer to

“Performance”for specifics.

NOTE: When installing PTFE diaphragms, it is important

to tighten outer pistons simultaneously (turning in

opposite directions) to ensure tight fit. (See “Maximum

Torque Specifications”).

NOTE: Some PTFE-fitted pumps come standard from the

factory with expanded PTFE gaskets installed in the

diaphragm bead of the liquid chamber. PTFE gaskets

cannot be re-used.

NOTE: In the event of a power failure, close the shut-off

valve if you do not want the pump to restart when the

power returns.

NOTE: The Safety Supplement document is a part of the

manual. Please refer to the Safety Supplement document

for a complete list of safety considerations including

considerations for safe operation and maintenance of

pumps marked for ATEX environments before starting the

pump.

SECTION 3

The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show flow pattern through the pump

upon its initial stroke. It is assumed the pump has no fluid in it prior to its initial stroke.

FIGURE 1 The air valve directs pressurized air to

the back side of diaphragm A. The compressed

air is applied directly to the liquid column

separated by elastomeric diaphragms. The

diaphragm acts as a separation membrane

between the compressed air and liquid; a

balanced load removes mechanical stress from

the diaphragm. The compressed air moves the

diaphragm away from the center of the pump.

The opposite diaphragm is pulled in by the shaft

connected to the pressurized diaphragm.

Diaphragm B is on its suction stroke; air behind

the diaphragm has been forced out to

atmosphere through the exhaust port of the

pump. The movement of diaphragm B toward the

center of the pump creates a vacuum within

chamber B. Atmospheric pressure forces fluid

into the inlet manifold forcing the inlet valve ball

off its seat. Liquid is free to move past the inlet

valve ball and fill the liquid chamber (see shaded

area).

FIGURE 2 When the pressurized diaphragm,

diaphragm A, reaches the limit of its discharge

stroke, the air valve redirects pressurized air to

the back side of diaphragm B. The pressurized

air forces diaphragm B away from the center

while pulling diaphragm A to the center.

Diaphragm B is now on its discharge stroke.

Diaphragm B forces the inlet valve ball onto its

seat due to the hydraulic forces developed in the

liquid chamber and manifold of the pump. These

same hydraulic forces lift the discharge valve ball

off its seat, while the opposite discharge valve

ball is forced onto its seat, forcing fluid to flow

through the pump discharge. The movement of

diaphragm A toward the center of the pump

creates a vacuum within liquid chamber A.

Atmospheric pressure forces fluid into the inlet

manifold of the pump. The inlet valve ball is

forced off its seat allowing the fluid being pumped

to fill the liquid chamber.

FIGURE 3 At completion of the stroke, the air

valve again redirects air to the back side of

diaphragm A, which starts diaphragm B on its

exhaust stroke. As the pump reaches its original

starting point, each diaphragm has gone through

one exhaust and one discharge stroke. This

constitutes one complete pumping cycle. The

pump may take several cycles to completely

prime depending on the conditions of the

application.

The Pro-Flo®R air distribution system incorporates two

moving parts: the air valve spool and the pilot spool. The heart of

the system is the air valve spool and air valve. This valve design

incorporates an unbalanced spool. The smaller end of the spool

is pressurized continuously, while the large end is alternately

pressurized then exhausted to move the spool. The spool directs

pressurized air to one air chamber while exhausting the other.

The air causes the main shaft/diaphragm assembly to shift to

one side —discharging liquid on that side and pulling liquid in

on the other side. When the shaft reaches the end of its stroke,

the inner piston actuates the pilot spool, which pressurizes and

exhausts the large end of the air valve spool. The repositioning

of the air valve spool routes the air to the other air chamber.
