3.7 Pressure relief valve
A integral relief valve is available. It can be
used regardless of the direction of rotation. A
manual override is also available.
The relief valve is designed to partially
protect the pump from damage caused by
over-pressurisation. The relief valve is preset
at 145 psi.
Over pressurisation can occur if :-
1. A valve is closed against the pump
discharge.
2. The product viscosity in the system is
significantly increased.
3. The pump speed is increased.
