water treatment equipment-Chemical Feed Pumps

With peristaltic pumping, no check valves are necessary.  The fluid is contained inside  a tube or hose held in a circular housing.  Pumping action occurs when the hose is squeezed against the housing and the rotor.  This repetitive flexure keeps the hose from clogging with slurry buildup.  The absence of check valves means that the highest maintenance aspect of feeding chemical slurries is eliminated.   Our Series 10 pumps feature a special patented reinforced hose for  long life.  Hose and rotor run in a special lubricant bath.

. Water treating chemicals, fed in slurry form, have long presented pumping problems Lime slurry, as used in traditional systems, has been particularly difficult.  For years, the diaphragm type feeder pump was felt to be the best feeding slurries.  The addition of the flushing manifold minimized maintenance.  Pump check valve problems were reduced but not eliminated.
