Piston Priming Pump.
The piston priming pump is mounted on top of the pedestal
at direct drive or on the gear box. The drive is implemented
over a belt. The piston priming pump can be switch on as
needed. It catches the eye through its high priming perfor-
mance.

tremely resistant plastic and the design as a double action
Automatic priming on the example of the N/NH series as well as
pump provide a very high operational safety.
