Valveless Methanol Metering Pump

Fluid Metering's valveless CeramPump QDX Hazardous Duty Metering Pump is designed for the low volume addition of methanol for nitrate removal in wastewater effluent in small and mid-size treatment facilities.

The release of high nitrogen concentrations of wastewater effluent into bays and watersheds is of great environmental concern as it can have a devastating effect on water ecosystems. Through a process known as "denitrification", water treatment facilities convert the excess nitrate into nitrogen gas, which is then vented into the atmosphere.
 
The pump is suited for methanol metering for waste water denitrification due to its valveless design. This is especially applicable in small to mid-size treatment facilities where flow rates are extremely low causing valved pump designs to become air-bound and lose prime.

The CeramPump has only one moving part in contact with the process fluid, a rotating and reciprocating ceramic piston. Similar to conventional piston pumps, the piston’s reciprocation performs the pumping function. However, this is where the similarity to conventional piston pumps ends.
The piston 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, thus eliminating the need for check valves. The pump drive is the company's QDX Hazardous Duty Drive, typically required for pumping methanol.
