3.3 Orientation
The pump can be mounted/oriented in any
horizontal direction. Vertically only with the shaft
pointing upwards.
3.4 Protection from too high pressures
The pump should be protected against too high
pressure by means of a pressure relief valve or a
bypass/unloading valve placed on the pressure
side.
The valve should be placed as close to the pump
as possible. The opening characteristics of the
valve must not result in peak pressures higher
than 200 bar (2900 psi).
The valve outlet must not be connected
directly to the pump suction line. It shall be
connected directly to the tank.
