Allweiler® Three Rotor Screw Pumps

Allweiler® Three-Rotor Screw Pumps

The Screw pump is one of the oldest and most useful of all pump designs. And whereas there are a myriad of other pump styles to fit almost every need, a screw pump handles special applications like no other. This is due to the pumps unique and highly efficient design which utilizes either a two or three rotor design for its use in pumping.

Pumping Applications

  • Lubricating Fluids
  • Lube Oils
  • Fuel Oils
  • Hydraulic Oils
  • Cutting Oils, etc.

How It Works

Three rotor designs utilize one power rotor and two drive rotors which spin inside the casing creating a rolling motion. This motion between the rotors and the fluid being pumped creates a barrier separating the rotors from contact and friction.

This action creates a seal inside the unit that prevents metal to metal contact while efficiently moving the medium being pumped at high pressure and especially with low viscosity fluids. We stock and supply multiple Screw Pumps and accessories for use in any environment and with any fluid.
