Valveless Chemical Treatment System Delivers Caustic Soda

The new chemical treatment system from Fluid Metering Inc. delivers caustic soda and other pH adjusting chemicals for treatment of water and wastewater.

Adding caustic soda to water and wastewater is typically accomplished using metering pumps, and diaphragm pumps represent the most widely used.  However, diaphragm pumps rely on four internal check valves for operation and caustic soda can crystallize causing problems in any pump using check valves. 

Fluid Metering’s “CTS” chemical treatment pump uses a valveless piston technology.  A single rotating and reciprocating ceramic piston accomplishes both the pumping and valving functions, thereby eliminating the need for check valves and the associated maintenance.
