Propulsion engine
Automatic priming
In the case of the automatic priming system, the priming pump is automat-
ically activated when the water column is interrupted.
Prerequisite:
The priming pump must remain selected in the background.
Functionality
The priming pump is activated and priming process started. If water is ex-
pelled at the priming pump, the priming pump is deactivated. The priming
procedure is completed.
When the water column breaks, the priming process will be repeated auto-
matically.
5.5 Propulsion engine
5.5.1 Propulsion engine
The propulsion engine of the portable pump is a petrol engine. The propul-
sion engine is a water-cooled alloy engine.
The propulsion motor is cooled via a closed cooling circuit by means of a
water/water and a water/air heat exchanger with electric fan.

5.5.2 Fuel tank
The fuel tank is made of fuel-resistant plastic.
The fuel tank is positioned beneath the propulsion engine, so that no fuel
can run onto the hot engine when refuelling.
For extra safety, the fuel tank is equipped with a safety cap. When the safe-
ty cap is opened, air first flows into the fuel tank so that there is pressure
equalisation between the fuel tank and the environment.
For safety reasons, there is no drain cock on the underside of the fuel tank.
This prevents the fuel tank from leaking in the event of damage, e g. off-
road. The fuel tank is fully drained by pumping dry.
