Compact, Vertical Suction Pump


Type VSM (Close Coupled)
Type VSMS (Split Coupled)


Small footprint for tight spaces

  • Vertically mounted top suction/top discharge pump fits where many pumps won’t.

Simplified installation

  • Same-size suction and discharge connections simplify piping.
  • VSM/VSMS pumps don’t require grouting.


Low life cost

  • Contoured suction baffle provides laminar flow to impeller.
  • Suction and discharge bends, eliminating the need for suction diffusers, angle type valves and/or elbows, which improves overall system efficiency.
  • Short shaft with minimum overhang reduces shaft deflection and improves bearing and me­chanical seal life.

Easier service

  • Top pull out design allows rotating assembly to be removed without disturbing the volute or piping for ease of maintenance and service.

Reliability

  • Double volute design helps to reduce radial thrust and prolong seal life.
  • Ductile iron construction provides the highest nozzle load in the industry.

Product Range

  • Sizes 4” to 10”
  • Flows up to 4100 GPM
  • Heads up to 400 feet
  • Horsepower up to 125 hp
  • Fluid temp up to 275°F

Applications

  • Cooling and refrigeration
  • Condensed water
  • Hot water
  • Process water
  • Heating systems
  • Pressure boosting
  • Water utility

Features & Benefits

  • Volute flanges allow for vertical piping – no need for horizontal suction pipe runs, elbows, suction guides, or discharge elbows
  • Double volute – extends seal and bearing life, minimizes noise and vibration, & improves operating efficiency
  • Type VSMS – spacer coupling allows easy disassembling and replacement of mechanical seal without removing motor
  • Ductile iron pump stand – no grouting requirements and minimal footprint
  • Heavy duty cast & machined motor bracket – rigid and reliable mounting surface with easy alignment
  • Case wear rings – reduce maintenance costs and maintain high efficiencies
  • Francis vane impeller design – increases efficiency and reduces NPSH required
  • Trimmed and balanced Impellers – customization, reduced noise and vibration, & prolonged seal and bearing life
  • Shaft sleeves –extend life of shaft and usable life of pump
