The basic elements of a hydraulic unit - motor and pump combined with coupling and pump support- are also available as independent assembly. Bolting on additional control elements and supplementary equipment enables the free modification of these compact units, making them deployable for numerous applications.
These hydraulic units with a conventional structure provide a solution between catalogue goods and special solutions. The tank is standardized on the one hand, and the controlling system can be adapted individually to the application on the other hand.
Adapted to concrete need, these hydraulic units are developed, designed and produced from the ground up. The model and dimensions as well as all further elements are individually adapted to achieve optimal results.
Otto Hydraulics not only offers hydraulic units and complete hydraulic systems but also individual hydraulic components. Whether it is a spare part or for your own production: the outstanding supplier network and a large stock lets Otto Hydraulics deliver a multitude of hydraulic components quickly, economically and reliably.
Otto Hydraulics not only offers hydraulic drives but also provides the required consumers. The hydraulic cylinders play one of the important roles here. Regardless whether single-acting, double-acting or more specialized models: Otto Hydraulics supplies exactly the cylinder needed for the application. As a result, Otto Hydraulics customers are provided with a complete hydraulic system from a single source.
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.
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).
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).
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.
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.
Versatile high pressure hydraulic pump for greater delivery rates. The possible working volumes range from 19 to 50 ccm. A large number of flange and shaft combinations are available. Depending on the type of this hydraulic pump, rotational speeds of up to 3,300 r.p.m. and pressure ranges (continuous operation) up to 276 bar can be applied.
Characteristic feature: Also available as multiple hydraulic pump and in combination with the W900!
Versatile high pressure hydraulic pump with working volumes from 5 to 31 ccm. A large number of flange and shaft combinations are available. Depending on the type of this hydraulic pump, rotational speeds of up to 4,000 r.p.m. and pressure ranges (continuous operation) up to 276 bar can be applied.
Characteristic feature: Also available as multiple hydraulic pump!
Compact high pressure hydraulic pump with working volumes from 0.8 to 5.7 ccm. At least three different flange and shaft combinations are available. The compact design of the of the W300 hydraulic pump enables its use in rotational speed ranges of up to 6,000 r.p.m.
