Electro-hydraulic Thrustors

HD Thrustor

The HD Electro-hydraulic Thrustor has a compact single push rod design and can operate at any angle between horizontal and vertical.

The force is constant throughout the stroke and the push rod can be stopped at any point in its stroke without damage.

The motor is Class F insulated as standard and the terminal box sides and cover are removable for ease of connection of cables.

All thrustors are available with alternative mountings for interchangeability with other types if required.

KT, TKF and KTX Thrustors

The KT Thrustor is a self contained electro-hydraulic unit and is operated by a standard D63 or D71 cage induction motor fitted with a cast iron frame and steel terminal box.

A CSA approved version can be supplied in all frame sizes and also a modified version is available for DIP applications.

The TKF Flameproof Thrustor has an integral stator / rotor unit in a flameproof enclosure for use in hazardous areas, certified to BS229 for Group I & II gases (petroleum and acetone vapours).

The KT and TKF Thrustors are designed to meet all relevant British Standard requirements They are carefully inspected and tested to ensure that they comply with these requirements, and are safe in operation.

The KTX Thrustors are explosion proof thrustors certified to EEx de Zone 1 Group II gas groups A, B and C, with a temperature class T4 available in thrustor sizes 1503 and above these thrustors are slightly taller (50mm approx.) than our standard models.
