Bellhousing/Coupling

Bellhousings are the component that forms the connection between a power source and a hydraulic pump.
 
Typically constructed out of aluminium alloy, they work with standard flanges up to 270 kW and are available in two constructions:

SINGLE PIECE
Constructed out of a single piece

COMPOSITE
Made using several components:
– base bellhousing with flange
– base bellhousing with distance ring and flange

At Hydraproducts, we offer standard bellhousings up to 225 frame and large bellhousing to 355 frame which is suitable for marine and offshore applications. Some useful points to consider when sizing up your bellhousing are listed below:

1. In order to make sure you select the right size bellhousing for your hydraulic power unit, you should first calculate the sum of the motor and pump shafts, remembering to take into account the thickness of the rubber spider or the dimensions of the polyamid ring attached to the coupling which must be compatible with your hydraulic motor and its power output.

2. Referring to the Catalogue pdf above, refer to the correct bellhousing in Tables 1,2,3 or 4 making sure the calculation from point 1. is either equal or less than the dimensions of the bellhousing.

3. Finally, Check the fixation points correspond with the pump and the bellhousing.


Drive Couplings are also typically manufactured from aluminium alloy. Used with a matching bellhousing they provide the connection between an electric motor with flange and a standard European spec 4 bolt gear pump with flange and a 1.8 taper shaft. They are compatible with electric motors ranging from D63 to D225 Frame fitments and power levels of up to 45Kw.

If you need any further information on our bellhousing and coupling ranges or advice on correct fitments, feel free to contact our experienced team on 01452 523352.

  • More about Micro Power Packs
  • Typical Applications

The HPU micro power pack has a single acting hydraulic circuit, the check valve and solenoid valve hold the cylinder load up. A high quality hardened steel check valve insert ensures low leakage and excellent load holding. Versions with Normally open/closed solenoid check valves and low noise check valves are available.

All of these micro hydraulic power packs have a precision engineered aluminium manifold that houses the hardened steel valves. A carefully developed micro hydraulic pump gives pressures up to 200bar. Each manifold has an integrated 90 micron filter element, ensuring all micro hydraulic systems are protected and give a long service life.

To drive the hydraulic pumps we offer DC motors from 150 to 800Watt, in 12V and 24VDC. 150 and 250Watt Fractional Horsepower AC motors as well as standard IEC frame AC motors from 0.18kW to 0.37kW.

Pump sizes range from 0.17cc to 1.48cc/rev.

Tanks from 0.1 to 1 Litre, all of which can be in vertical (tank uppermost) or horizontal orientation.

Typical applications include :- 

    Mobility lifts where Wheelchairs are lifted from vehicles
    Micro power packs for through floor lifts.
    Door and gate opening actuators

Hydraproducts offers its worldwide OEMs and distributors reliable products through design and manufacturing expertise. The quality of in-house design, manufacturing and experience in micro hydraulic power units ensures a match to your requirements.
