ABSTRACT:
A pressure relief arrangement for a pump (10) which includes a pump housing assembly with a pumping chamber (25) therein, the pump housing assembly including a section (41) mounted for movement between a normal operating position and a venting position, a shearing element (45) being adapted to retain the section in the normal operating position, the section (41) being mounted so that upon the pressure within the pumping chamber (25) can act on the section (41) and upon the pressure within the pumping chamber (25) reaching a specified pressure, the shearing element (45) will fail thereby permitting movement of the section (41) from the normal operating to the venting position.
