Methanol Metering Pump Goes Valveless

Methanol Metering Pump Goes Valveless

For small and mid-size treatment facilities, the valveless QDX metering pump handles low-volume addition of methanol for nitrate removal in wastewater effluent. A rotating and reciprocating ceramic piston is the pump’s only moving part that comes in contact with the process fluid. Similar to conventional piston pumps, the piston’s reciprocation performs the pumping function. However, the piston also simultaneously rotates during the pumping cycle and is synchronized to alternately open and close the inlet and outlet ports of the pump effectively functioning as a valve. At no point are the inlet and out ports interconnected, eliminating the need for check valves. For additional information, visit
