GP 200M

GP200MThe Sykes AmeriPumps GP200M automatic priming centrifugal pump is the world standard for temporary high volume pumping.

Excelling in sewer by–pass, well–point dewatering, and straight dewatering, the GP200M performs the work of all three. The Sykes Univac vacuum system allows the GP200M to prime and re–prime automatically; to operate with the suction intake intermittently exposed to atmosphere; and to run dry for indefinite periods of time without harm to the pump. The capacities to handle solids up to 3″, maximum flows of 3250 gpm, and up to 175 ft of dynamic head, makes the GP200M the most versatile pump available in its class. Sound attenuation is standard with the GP200M.


  • Compact sound attenuated unit, meets OSHA noise workplace requirements.
  • Mounted on a two–wheel highway trailer system, pumpset can be converted to a skid in minutes.
  • Self–contained fuel tank, allows more than 28 hours of operation between refueling.
  • Close coupled centrifugal pump with vacuum priming system mounted to a diesel engine. Also available in electric drive or as a bare shaft pump end.
  • Engine containment to prevent environmental spills.
  • Most flexible pumpset in the industry – handles raw sewage, slurries, well–point dewatering and liquids with solids up to 3″ diameter.
  • Sykes Univac patented vacuum priming system, with back flush system to allow clearing of suction pipe with the push of a lever.
  • Patented, dry running vacuum pressure seal allows for continuous dry running periods and easy, inexpensive field replacement.
  • Standard engine – Caterpillar C4.4T producing 99 HP at 2000 rpm. Available with a variety of engines including a Cummins, John Deere, and Isuzu.
