WILDEN PUMP & ENGINEERING, LLC

OPERATION: The Pro-Flo

®

 and Pro-Flo V™ pumps are 

pre-lubricated, and do not require in-line lubrication. 
Additional lubrication will not damage the pump, 
however if the pump is heavily lubricated by an 
external source, the pump’s internal lubrication may 
be washed away. If the pump is then moved to a non-
lubricated location, it may need to be disassembled 
and re-lubricated as described in the ASSEMBLY/
DISASSEMBLY INSTRUCTIONS.

Pump discharge rate can be controlled by limiting the 
volume and/or pressure of the air supply to the pump. 
An air regulator is used to regulate air pressure. A needle 
valve is used to regulate volume. Pump discharge rate 
can also be controlled by throttling the pump discharge 
by partially closing a valve in the discharge line of the 
pump. This action increases friction loss which reduces 
fl ow rate. (See Section 5.) This is useful when the need 
exists to control the pump from a remote location. 
When the pump discharge pressure equals or exceeds 
the air supply pressure, the pump will stop; no bypass 
or  pressure  relief  valve  is  needed,  and  pump  damage 
will not occur. The pump has reached a “deadhead” 

situation and can be restarted by reducing the fl uid 
discharge pressure or increasing the air inlet pressure. 
The Wilden Pro-Flo

®

 and Pro-Flo V™ pumps run solely 

on compressed air and do not generate heat, therefore 
your process fl uid temperature will not be affected.

MAINTENANCE AND INSPECTIONS: 

Since each 

application is unique, maintenance schedules may 
be different for every pump. Frequency of use, line 
pressure, viscosity and abrasiveness of process fl uid 
all affect the parts life of a Wilden pump. Periodic 
inspections have been found to offer the best 
means for preventing unscheduled pump downtime. 
Personnel familiar with the pump’s construction and 
service should be informed of any abnormalities that 
are detected during operation.

RECORDS: When service is required, a record should 
be made of all necessary repairs and replacements. 
Over a period of time, such records can become a 
valuable tool for predicting and preventing future 
maintenance problems and unscheduled downtime. In 
addition, accurate records make it possible to identify 
pumps that are poorly suited to their applications.

Pump will not run or runs slowly.

1.  

Ensure that the air inlet pressure is at least 0.4 bar 
(5 psig) above startup pressure and that the differential 
pressure (the difference between air inlet and liquid 
discharge pressures) is not less than 0.7 bar (10 psig).

2.  

Check air inlet fi lter  for  debris  (see  recommended 
installation).

3.  

Check for extreme air leakage (blow by) which 
would indicate worn seals/bores in the air valve, 
pilot spool, main shaft.

4.  

Disassemble pump and check for obstructions 
in the air passageways or objects which would 
obstruct the movement of internal parts.

5.  Check mating surfaces of fl ap valve assembly.

6.  

Check for sticking ball check valves. If material being 
pumped is not compatible with pump elastomers, 
swelling may occur. Replace ball check valves and 
seats with proper elastomers. Also, as the check 
valve balls wear out, they become smaller and can 
become stuck in the seats. In this case, replace balls 
and seats.

7.  

Check for broken inner piston which will cause the 
air valve spool to be unable to shift.

8.  Remove plug from pilot spool exhaust.

Pump runs but little or no product fl ows.

1.  

Check for pump cavitation; slow pump speed down to 
allow thick material to fl ow into liquid chambers.

2.  

Verify  that  vacuum  required  to  lift  liquid  is  not 
greater than the vapor pressure of the material 
being pumped (cavitation).

3.  

Check for sticking ball check valves. If material being 
pumped is not compatible with pump elastomers, 
swelling may occur. Replace ball check valves and 
seats with proper elastomers. Also, as the check 
valve balls wear out, they become smaller and can 
become stuck in the seats. In this case, replace balls 
and seats.

Pump air valve freezes.

1.  

Check for excessive moisture in compressed 
air. Either install a dryer or hot air generator for 
compressed air. Alternatively, a coalescing fi lter 
may be used to remove the water from the 
compressed air in some applications.

Air bubbles in pump discharge.

1.  Check for ruptured diaphragm.
2.  

Check tightness of outer pistons (refer to Section 7).

3.  

Check tightness of fasteners and integrity of o-rings 
and seals, especially at intake manifold.

4.  Ensure pipe connections are airtight.

Product comes out air exhaust.

1.  Check for diaphragm rupture.
2.  Check tightness of outer pistons to shaft.
