Suggested Installation, Operation, Maintenance and Troubleshooting

 

 

 

 

This illustration is a generic 
representation of an air-operated 
double-diaphragm pump.

 

 
 

 

 

 

 

 
 
 

 

 

 

 

 

 

 

 

 
 
 

 

 

 

 

 

 

NOTE: 

In the event of a power failure, the shut-off 

valve should be closed, if the restarting of the pump is 
not desirable once power is regained. 

Air-Operated Pumps: 

To stop the pump from operating in an 

emergency situation, simply close the shut-off valve (user-
supplied) installed in the air supply line. A properly functioning 
valve will stop the air supply to the pump, therefore stopping 

output. This shut-off valve should be located far enough away  
from the pumping equipment such that it can be reached safely  
in an emergency situation. 

Operation 

The P1500 is pre-lubricated, and does not require in-line 
lubrication. Additional lubrication will not damage the pump, 
however if the pump is heavily lubricated by an external source, 
the internal lubrication may be flushed out. If the pump is then 

moved to a nonlubricated location, it may need to be 
disassembled and re-lubricated as described in the 

DISASSEMBLY / REASSEMBLY 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 flow 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 wil

l not occur. The pump has reached a “deadhead” situation and can 

be restarted by reducing the fluid discharge pressure or increasing the air inlet 
pressure. Wilden Pro-Flo

pumps run solely on compressed air and do not 

generate heat; therefore, your process fluid 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 fluid 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.
