6.3. Hydraulic connection
➔
Only connect components to the pump that are designed to
handle the hydraulic data of the pump (see
Chapter 4, Technical data).
➔
Only use hoses that are suitable for the maximum operating
pressure of the pump (see Chapter 4).
➔
Only use hoses that are sufficiently chemically resistant to the
liquids being pumped.
6.3.1. Connecting the pump
Arrows on the pump head indicate the flow direction.
Remove the protective caps from the connections.
Connect the suction and pressure lines.
Keep the suction line as short as possible in order to keep the
priming process as brief as possible.
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.
Check that the hoses and transition joints are fitted correctly
and securely.
Check that the system is leak-tight.
