Magnetic driven centrifugal pump constructed of polypropylene, Ryton, Kynar, 316SS and Hastelloy C. March offers three different levels of corrosion resistant design levels.
AC Series- Using air cooled (open motors) and may contain stainless steel parts.
BC Series - Using blast cooled enclosed motors and plastic encapsulated liquid containing parts and Viton® O-ring seal.
TE Series - Using TEFC motors and encapsulated liquid containing parts and Viton® O-ring seal.
March magnetic driven pumps are corrosion resistant to a wide range of chemical solutions including acids, alkalies and caustics up to 180 degree F. There is no shaft seal, so there is no seal wear, leaking or squeal. There is no seal friction to cause loss of pumping power. The only moving parts inside the pump volute are the impeller magnet assembly and the bushing that rotates on the pure ceramic spindle. Powerful impeller and drive magnets provide full torque, prevent slippage and give instant start-up. Carbon impeller bushing can be provided as an option -- this allows the pump to run dry with out damage for short periods of time.
March TE Series magnetic driven pumps are constructed of polypropylene and/or Ryton® (motor bracket, impeller magnet assembly, encapsulated impeller assembly and pump housing), carbon or Chemloy or Ryton/Teflon® (bushing), ceramic (spindle and thrust washers) and Viton® O-ring. All motors are totally enclosed fan cooled.
Model SP-TE-7P-MD is supplied as a self priming unit using a 1HP motor. Performance is similar to the TE-7R-MD pump. This pump can prime up to 10 feet. Pump is available in polypropylene construction or with optional Kynar liquid end construction.
This pump will retain liquid within the priming chamber to assure that the pump will prime. The chamber must be initially filled. A drain connection is provided to empty the chamber prior to service and periods of long shut down.
A priming chamber, constructed of polypropylene is available for Model 4 through 6.
