5.3.  Pneumatic connection 

  Only connect components to the pump that are designed to 

handle the pneumatic data of the pump (see Chapter 4, Tech-
nical data)  

  Only use hoses that are suitable for the maximum operating 

pressure of the pump (see Chapter 4) 

  Only use hoses that are chemically resistant to the media be-

ing pumped 

  If ambient air is sucked in, use a filter to protect pump from 

dust 

5.3.1. Connecting the pump 

 

Arrows on the pump head indicate the flow direction. 

1.  Remove the protective caps from the hose

 

connections. 

2.  Connect the suction and pressure lines. 

3.  If the pump is used to build up pressure, make sure that all 

transition joints between hose and pump are secure in order to 
ensure that the hoses cannot come off. 

4.  Check that the hoses and transition joints (hose connect-

or/hose) are fitted correctly and securely. 

5.  Check that the system is leak-tight.
