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 .
