CeramPump® QXD
Hazardous Duty Metering Pump
The CeramPump® QDX Hazardous Duty Metering Pump from Fluid Metering has proven to be an excellent choice for methanol metering for wast water denitrification due to its unique valveless design. This is especially true for applications 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 FMI’s QDX Hazardous Duty Drive, typically required for pumping methanol.
