Hydraulic units – Solutions for customers

Otto-Hydraulics GmbH offers hydraulic units for the entire application area of hydraulics. Our offer includes everything from a modifiable compact unit to individualised hydraulic units with conventional structure to custom-made products which we develop and design ourselves for specific customer applications. In addition, we offer hydraulic cylinders, hydraulic components, hydraulic pumps and accessories and spare parts, such as current dividers or pressure control valves for diverse application areas.

Compact units of the BF series

Due to their low overall height, our compact units of the BF series are suited for confined installation spaces (e.g. in lifting tables). Further hydraulic circuits are possible beyond the customary lifting-lowering module as standard application for the lifting devices. BF compact units can be installed horizontally as well as vertically, but are designed for intermittent operation; continuous operation is only possible with reduced power. Like our hydraulic units from the ZPU series, our BF compact units are commended, among other things, for application in lifting devices, for handling systems and tool machines.

Compact units of the ZPU series

The appeal of the ZPU20 and ZPU30 compact unit series is their increased power density and a multi-functional supporting plate for control elements and components. For that reason the ZPU hydraulic unit is well suited for use in workshop technology for lifting tables, car lifts, stroke roofs, supports and testing equipment. It is also possible to use it in tool machines as clamping pressure supply. The ZPU20 is available with 0.75 kW. The compact units of our ZPU30 series offer even more power (3 kW/1.5 kW)

Compact unit for mobile hydraulics

Our compact units (DC) He1 and He2 are developments with differing performance ranges and variable steel or plastic tanks, as are chiefly installed in mobile hydraulics.

Standard units with individual control system

Our conventional hydraulic units are a compromise between standard units and custom-made products: whereas the tank is standardised, the control system can be adapted to different applications according to customer requirements.

Optimised custom-made products

We develop hydraulic units as custom-made product in close cooperation with our customers – the only way to achieve perfect results. Not only is it possible to develop and produce individual units, but the model, dimensions and functional elements also can be optimised to the customer’s application.

Compact units

ZPU20

Short description
The hydraulic unit of the ZPU20 series has a tank cross-section of 110x150 mm and covers a power range of up to 0.75 kW (in short-time operation). These ultra-compact units are perfectly suited for actuation of clamping functions on tool machines (tool clamping, workpiece clamping device), braking equipment, etc. This hydraulic unit series uses control valves of the pump size Cetop 2 (NW4).

The variant ZPU21 is available with a 1-phase 230 V motor (0.55 kW).

ZPU30

Short description
The power range for this compact hydraulic unit range up to 3 kW at short-time operation. The tank cross-section of 150x150 mm also yields a very low installation height for this performance data at horizontal installation position (vertical installation possible as option). Among other things, the ZPU30 hydraulic unit has proven its worth when deployed for lifting platforms, tilting devices, activating of flaps and hatches, loading ramps and workshop equipment.

The variant ZPU31 is available with a 1-phase 230 V motor (0,75 kW).

BF10

Short description
The He2 hydraulic unit is a compact direct current unit (DC) used mainly for mobile hydraulics. However, it can be modified for other applications as well.

› Further information   |   › Design types

BF25

Short description
The BF25 is a hydraulic unit with a low installation height that is oriented to the flange diameter of the utilised electric motor (only 308 mm for this type). This hydraulic unit series was originally designed for lifting technology (lifting tables, working platforms, etc.), but it can also be modified and expanded for various other applications.

He2 (AC)

Short description
The He2 (AC) compact unit is a combination of the He2 intermediate flange and the corresponding containers with a conventional three-phase motor. In contrast to the ZPU series (oil-immersed motor), the motor here is outboard and the control block is screw-mounted to the intermediate flange.

As with the He2 (DC), capacities up to 4 kW can be installed. Because it is possible to install a steel container with up to 12 litres, the compact unit He2 (AC) can also be used for applications with increased oil requirement.

Compact units (DC)

He2

Short description
The He2 hydraulic unit is a compact direct current unit (DC) used mainly for mobile hydraulics. However, it can be modified for other applications as well.

In contrast to the smaller He1, higher capacities up to 4 KW can be installed. With the ability to install a steel tank with up to 12 litres, the He2 hydraulic unit can also be used for applications with increased oil requirement.

He1

Short description
The He1 hydraulic unit is a compact direct current unit (DC) used mainly for mobile hydraulics. However, it can be modified for other applications as well.

Although the performance range is not quite as high as the He2, the He1 is a more compact hydraulic unit and is also available with a larger plastic tank than the He2.
