Series 540 - Heavy Duty End Suction Centrifugal Pump

Material of Construction:

  • Cast iron  

Design Features:

The Series 540 Heavy Duty End Suction Centrifugal Pumps are designed for industrial services.   Viking Pump Centrifugal pumps are offered in a wide range of size and various materials of construction capable of meeting applications required in today’s industry.

  • Impeller is of non-clogging type with extra heavy vanes. Semi-open design permits passing of foreign material and the handling of clean or dirty liquids. Impeller is statically and hydraulically balanced.   
  • Shaft is of high tensile steel accurately machined to ensure proper fit of impeller and bearings.   Ample diameter prevents deflection at all operating speeds.
  • Casing is vertically split design. Discharge may be rotated every 45 degrees from regular top vertical position to facilitate piping. Casing has tapped openings for priming, vent, drain and gauge connections. Designed for 150 PSI maximum working pressure.
  • Axial Shaft Adjustment permits impeller to be adjusted for end clearance, maintaining pumping efficiency at all times.  Shaft adjustment nut prevents any forward axial movement of impeller during pump operation.
  • Stuffing Box is a multi-ring packed gland, to keep leakage to an absolute minimum.  Mechanical seals in Buna-N, Viton, and PTFE are available as an optional feature.
  • Bearings are heavy duty, ball type, grease lubricated.  Bearing housing has integral support foot for accurate, permanent alignment of bearings and rigid support of shaft.
