Crane Deming Series 3000 end-suction centrifugal pump sets the industry standard for low maintenance, high performance, and rugged reliability. The ultra-dependable industrial pump is available in seven basic frames and in a complete range of 44 sizes, from 1" to 8" discharge.

Built for continuous operation in general industrial, OEM and HVAC service, the pumps come in frame-mounted and close-coupled designs using both JM and JP standard motor shaft dimensions.

The 3000 Series features a hydraulically balanced, computer-designed, enclosed and semi- enclosed impeller to ensure the highest hydraulic efficiency available in the pump industry. Maximum interchangeability of parts allows for reduced parts inventories. Other features include a rugged, one-piece casting for suction head and casing; back pull-out design for ease of maintenance; regreaseable bearings; and a two-year warranty against defects in materials and workmanship.

Industrial and HVAC users like 3000 Series end-suction pumps because they provide continuous service with essentially no maintenance. OEM users like them because of their reliability, low maintenance and compact design.
