mounting

  The pump exhaust air may contain 

contaminants. Ventilate to a remote area. 
See Air Exhaust Ventilation on page 9.

  Never move or lift a pump under 

pressure. If dropped, the fluid section may 

rupture. Always follow the Pressure Relief 
Procedure on page 10 before moving or 
lifting the pump.

1.  Be sure the mounting surface can support 

the weight of the pump, hoses and 
accessories, as well as the stress caused 
during operation.

2.  For ease of operation and service, mount 

the pump so air inlet, fluid inlet and fluid 

outlet ports are easy accessible.

Grounding

The equipment must be grounded. 
Grounding reduces the risk of static and 
electric shock by providing an escape wire 
for the electrical current due to static build 
up or in event of a short circuit. In the site 
housing a grounding connection is included.

 

Check your system electrical continuity 
after the initial installation. Set up a regular 
schedule for checking continuity to be sure 
proper grounding is maintained.

Follow your local fire codes. When pumping 
flammable fluids, 

always ground the entire 

fluid system as described.

Air Line

See recommended installation drawing  
on page 7.

1.  Install an air regulator and gauge. Set 

pressure of the driving air should be 
limited to the pressure required to run 
the pump on the desired working point. 
Setting the pressure too high will cause 
higher wear of the pump and will increase 
the compressed air consumption. The 

fluid stall pressure will be the same as the 

setting of the air regulator.

2.  If the air regulator do not have a bleed off 

function to relieve trapped air, or the air 
regulator is not placed close to the pump, 
locate a bleed-type master air-valve close 
to the pump. Be sure the valve is easily 
accessible from the pump. 

MPa/bar/PSI

Trapped air can cause the pump to cycle 
unexpectedly, which could result in serious 
injury from splashing.

3.  The master air valve will be used to 

regulate the flow rate of the air to the 

pump. By using a throttle valve, it is 
possible to regulate the pump speed even 
at the lower end of the curves.

4.  Install a grounded, flexible air hose 

between the accessories and the pump 
air inlet. The inner diameter of the hose 
have to be the same diameter of the air 
connection of the pump or bigger.
