How does a Modular External Gear Pump work?
The pump shaft operates, moving the two external gears that draw liquid into the port. The liquid fills the space between the gear and is transported towards the pump outlet as the shafts turn.
By-Pass/Pressure Relief Valve Operation:
The valves protect the pump and drive unit from over-pressurisation by diverting excess fluid from the discharge side to the suction side, allowing recirculation until normal flow resumes.
By-Passes can be fitted in pipework or directly on the pump head and are adjustable to suit changing system requirements.
