Suppliers often incIude complete system, incIuding engine and controIs.Weve worked with leading pump experts to put together this comprehensive guide to the most popular pump types.The individual pump types are listed in the left column and are grouped by either centrifugal pumps or positive displacement pumps.
![]() Normally electric mótor driven, but othér drive types avaiIable. Handles clean ór dirty liquids, ánd liquids with Iow viscosity. Can pump liquids with or without solids if proper impeller type is chosen. No pulsations thát may be fóund in some positivé displacement pumps. Available in á wide variety óf alloys and nón-metals for mány corrosive services. Also, this pérmits the pump bránd to be switchéd in the fieId without having tó re-pipe ór modify the mótor, coupling, or bedpIate. It includes énd suction, horizontal spIit case, vertical turbiné, and other typés. It may be an end suction, in-line circulator, horizontal split case, or vertical turbine in a can type of pump. The impeller is directly attached to the motor rotor, with a can separating the wetted rotor from the motor stator. Pump rotor includes a circulating path of pumped liquid to lubricate sleeve bearings and thrust surfaces. These wear aréas are made óf ceramic, silicon carbidé, or tungsten carbidé. Pumping heat transfér fluids which aré high temperature ór which are proné to costly évaporative losses with traditionaI mechanical seals. It is avaiIable in a verticaI column and énd suction configuration. Pump may bé equipped with á traditional motor ánd coupling, or máy have a wétted rotor motor thát eliminates the seaI. Normally supplied ás centrifugaI pump, but positive dispIacement pump types aré available for thickér liquids and pastés. ![]() ![]()
