Steering gear with conventional pumps 

The steering gears fitted with a 

conventional pump system

 have separate pump units, the pumps are 

constantly running and the oil is controlled by a manoeuvring valve.

 

The pump unit consists of a tank 

with foundation, manoeuvring valve (on steering gear for PU50 andFV2 or FV10 valve), return filter and 

vane pump (PU30 uses gear pumps) with flexible coupling. The electric motor is flanged to the top plate 

(flanged to the side on PU30).  

The pump runs submerged in oil and an arrow on the pump flange indicates the direction of rotation. 

The pump unit is to be connected by three pipes; two to the distributing valve on the actuator and one 

to the oil reservoir. (Different types of installations will have individual variances).
