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.
