Which Pump is Right for Me?

Flooded Inlet, Mobile Fluid Type

Gear Pumps
Gear Pumps

Each of our gear pumps has a pair of rotating meshed gears in a surrounding chamber with very tight clearance to

  • Create suction at the inlet port.
  • Move the liquid between the teeth of the gears and casing walls.
  • Direct the fluid flow to the outlet.

Mobile Fluid Type, Dry Run, Self-priming

Peristaltic Pumps
Peristaltic Pumps

Our peristaltic pumps, also known as squeeze-tube pumps, propel liquid with rotating rollers, attached to a motor that turns in a circular motion and that

  • Squeezes a tube or hose.
  • Creates a vacuum at the inlet end of the hose.
  • Squeezes the fluid through the hose.
  • Discharges the fluid at the outlet.

Flooded Inlet, Mobile Fluid Type, Submersible

Magnetic Drive Pumps
Magnetic Drive Pumps

The impeller of our magnetic drive pumps

  • Moves fluid through a chamber in which spinning vanes create pressure at the inlet.
  • Generates spin with two sets of adjacent rotating magnets in the shape of cylindrical shells.

The cylindrical shells have two layers

  • The outer layer connected to a power source
  • The inner layer connected to the impeller.

Dry Run, Self-priming, Viscous Fluid Type

Diaphragm Pump
Diaphragm Pump

Each of our diaphragm pumps works with a membrane, connected to a power source on one side and a liquid chamber on the other side.

The power source expands and contracts the diaphragm, which forces fluid into the chamber during expansion and outward during contraction.
