Hydraulic units — Custom-made solutions from in-house production

Hydraulic units combine a pump, electric motor, tank and valve technology into a ready-to-operate drive and control unit for hydraulic systems. Motrac Hydraulik GmbH develops and manufactures customer-specific units in Willich in three series: the modular IMAV compact units of the IKA series and the IMAV hydraulic units of the IHA series for small to medium construction sizes with tank volumes of up to several hundred liters. Manufactured from the individual unit to the series. Each unit is tested and delivered ready for installation with documentation.

Construction and operation

A hydraulic unit combines the central components of a hydraulic drive into a compact assembly: an electric motor drives the pump, which feeds hydraulic fluid from a tank; directional, non-return, and flow valves control and ensure the volume flow to the actuators downstream. Motrac combines standardized quality components with custom-developed special valve blocks that integrate several functions. This reduces external piping and creates a compact, ready-to-install assembly. Depending on the model, steel construction work and individual color customization complement the solution.

List of housing developments

IKA compact units

Customized compact units of the IKA series are modular and configurable in up to six variants. They combine standard components with special valve blocks, integrating functions and thereby enabling a compact, low-pipe design. Typical applications include units with multiple valve connection plates or for direct mounting on a hydraulic cylinder, for example for cylinder locking.

IHA hydraulic units

The IHA series covers small and medium-sized series of units with tank volumes of up to several hundred liters. It is often used as a replacement solution for corroded existing systems – for example, as a compact block solution with its own block design and oil tank, or with a double pump for higher flow rates.

Typical areas of application

Motrac hydraulic units are used across industries – in mechanical engineering, mobile work machines, and the marine industry. As an established partner for original equipment manufacturers as well as for direct replacement needs, Motrac covers virtually all mobile and stationary applications, from one unit to any desired number.

Selection criteria for hydraulic units

Series and construction size

The IKA series is suitable for modular, compact solutions with multiple functions in a compact space; the IHA series is suitable for larger tank volumes up to the multi-digit liter range.

All three series are available both as standard configurations and as customized special solutions—from individual production to medium-volume series.

Frequently asked questions about hydraulic units

What series of hydraulic units does Motrac offer?

Motrac offers two series of units: the modular compact units IKA and the hydraulic units IHA for small to medium-sized construction projects.

Yes. Motrac manufactures both individual pieces and small and medium-sized series – from the individual special solution to initial series production for original equipment manufacturers.
