Centrifugal Pumps

John Morris Scientific offers centrifugal pumps at high flow rates, low pressures, and pulseless flow at a low price. They're ideal for your general transfer applications.

Our centrifugal pump range offers flow rates for clean liquids (no particulates) up to 2200 LPM and pressures up to 25 bar. They also include low-cost centrifugal pumps for water transfer and chemically resistant models for highly corrosive chemicals.

The simple design of a centrifugal pump means quick installation, low maintenance, and easy repair. Most centrifugal pumps must be gravity fed or utilized with a priming chamber; some are self-priming. You can control the flow rate by restricting the flow at the outlet with a nozzle or valve, and in most cases, you can restrict the outlet indefinitely without damaging the pump. However, centrifugal pumps should not be run dry.

Types of Centrifugal Pumps

Mechanical Coupling:

  • Magnetic drive centrifugal pumps operate with a magnetic field that couples the impeller and motor together. There are no shafts or seals connecting the impeller and motor. Therefore friction loss, wear, contamination and leakage caused by these shafts and seals are eliminated.
  • Mechanically coupled centrifugal pumps utilize a rotating impeller driven by a shaft with a seal that is connected to the motor. They are often less expensive than magnetic drive and can achieve high flow-rates and pressures.

Why use a Centrifugal Pump?

  • Electric driven and suitable for continuous duty
  • Excellent pulseless flow
  • Fluid transfer at high flow rates, low pressure
  • Available in a range of materials

Typical Applications for Centrifugal Pumps

  • Filling/draining
  • Cooling tower transfer
  • Filtration of corrosives, caustics, dyes, soaps, brines, and other cleaning fluids
  • Feed pumps for spraying systems
  • General fluid transfer
  • Line cleaning/irrigation
  • Pilot plant processing
