Flexible Tooth Coupling for CAT 340 / 350 / 5CP Pumps

A high-quality, durable flexible coupling designed for direct connection of the electric motor shaft to CAT Pumps’ 340, 350, and 5CP series high-pressure pumps. It ensures stable torque transmission, effectively dampens vibrations, and compensates for minor misalignments, which directly extends the service life of the pump’s bearings and seals.

Key benefits:

  • Compatibility: Designed specifically for the iconic CAT 340, 350, and 5CP series car wash pumps (e.g., 5CP2120W).
  • Design: Lightweight, corrosion-resistant aluminum hubs with a factory-drilled hole for a mounting key.
  • Drive protection: A flexible insert made of engineering rubber effectively absorbs shocks and reduces system noise.

Complete Drive Coupling for CAT Pumps High-Pressure Pumps

A reliable claw coupling is a key component connecting the hydraulic system to the drive motor in touchless car wash stations and professional pressure washers. Thanks to the use of two-piece aluminum hubs and a flexible rubber coupler, this component acts as a mechanical barrier that protects the pump shaft from overloads and microvibrations generated during high-pressure operation.


Industrial-Grade Design and Materials

The coupling is designed to withstand continuous operation under harsh conditions (moisture, high loads):

  • Aluminum Hubs: Made of a lightweight and durable aluminum alloy, featuring a precision keyway that ensures a secure, play-free fit on the shafts.
  • Flexible insert: Durable engineering rubber with optimal hardness, resistant to aging, oils, and torsional impacts.

Technical Specifications and Compatibility:

  • Application: CAT Pumps high-pressure pumps
  • Compatible Models: 340 Series, 350 Series, 5CP Series (e.g., 5CP2120W, 5CP2150W, 5CP6120)
  • Coupling Type: Tooth-type, flexible
  • Material: Aluminum / Engineering rubber
  • Function: Vibration damping, shaft misalignment compensation, quieter unit operation (noise reduction)

Installation and Service Instructions

To ensure maximum service life of the drive assembly, carefully verify the coaxiality of the motor shaft and the CAT pump before fully tightening the mounting bolts. Regular inspection of the rubber damping insert helps prevent costly mechanical failures and downtime at the car wash station.
