Totally oil free, clean and completely safe for people, processes and products.

As a result of employing advanced materials, high velocity and loaded sliding surfaces can operate effectively with water as their only coolant/lubricant.

The potential for cross contamination of the system fluid or the lubricating oil is removed.

The result is an exceptionally small light weight product.

Each bearing employs a hard/soft interface that minimises vibration and ensures a low noise and high efficiency operation.

Manufactured in A.I.S.I. 316 stainless steel as standard the product offers excellent resistance to corrosive fluids.

The materials utilised internally can be selected to suit the most appropriate combinations for not just tap water but also sea water and various other fluids.

Minimal pulsation is experienced with these units due to the multiple piston design and the high operational speeds.

The physical size of the motor in comparison to the power generated offers one of the most compact drive solutions

Geared Motor Assemblies

A standard range of epicyclic gearboxes are available for operation below the recommended minimum speed.

Temperature

The units will generate full performance from 2°C to 50°C. For temperatures below freezing an environmentally friendly antifreeze is available; ask for the glycol data sheet. Operation above 50°C is possible, but the volumetric efficiency of the unit will be affected consult TWHC and specify the maximum operating temperature.

Filters

All incoming water to the motors must be pre-filtered to a nominal rating of 10µm (25µm absolute) with a filter element rating of ß10 = 75 or better. Return line filtration is advisable on closed loop systems. High pressure filtration may also be considered.

Shaft Loading

Radial and axial loads are not permitted on the motor output shaft.

Operation

It is advised that the motors are operated on a regular basis to ensure the appropriate starting torque is maintained.
