3LS Series Three Rotor Screw Pumps

The 3LS Series pump is a three rotor screw pump manufactured by Shanley Pump and Equipment, Inc. at our main facility. The pump has a main screw which is connected to the power source. Pump rotation is normally clockwise as viewed from the drive end. There are also two idler rotors which are driven hydraulically by the main rotor.

As the pump turns, these three screws intermesh and run inside of a pump housing. This results in closed cavities which transfer the liquid from the suction to the discharge side of the pump as the pump rotates. Due to the close tolerances of the pump design, a precise flow per pump revolution is achieved.

The 3LS Series Pumps are designed for handling lubricating fluids. these fluids are found most commonly in applications where forced oil lubrication is required for rotating machinery. Other applications may include:

  • Hydraulic services
  • Oil Circulation
  • Fuel Transfer
  • Burner fuel services

Many other types of services are served by these 3LS Series three rotor screw pumps, if the fluid has lubricating properties and the service is within the design parameters of the pump
