  • Metering Pump Principles | Milton Roy

    To achieve this, the metering pump is supplied with check valves at the suction and discharge connection points. The check valves contain and release the chemical based on system conditions and gravity. During the suction portion of the stroke, the motion of the piston lifts the suction ball check from its seat allowing liquid into the pump.
