Water Pump Accessories, Hydraulic Motors and Couplings

The right hydraulic motor turns a good water pump into a reliable pumping system. Flow, pressure and speed all depend on matching the motor displacement to the pump and to the hydraulic circuit driving it, and a poor match shows up quickly as low output, overheating or premature wear. That is true on a water truck, a fire unit, an irrigation rig or any other hydraulically driven plant.

T-Rex stocks the motors and couplings that we fit to our own XHD pumps, so you can complete or repair a drive with parts we know work together. The range includes Permco and Vivoil hydraulic gear motors in a choice of displacements with 13 tooth spline shafts, a 25cc hydraulic piston pump and motor, and shaft kits and couplings for both our hydraulic water pumps and bare shaft pumps. For wear parts such as seals and impellers, see our water pump spares.

If you are unsure which motor suits your pump and hydraulic system, our team can help you size it correctly. Browse the accessories below or get in touch with T-Rex for advice and pricing.
