We stock a range of OT-Oil Technology hydraulic gear pumps which offer excellent levels of strength and durability; with cast iron end flanges and aluminium alloy body, they are suitable for use in heavy working environments and cope well with the transmission of high hydraulic pressures.

High levels of volumetric and mechanical efficiency are realised inside the high strength construction. Due to the high quality materials used in the construction of the pumps, they are low weight and offer decreased installation dimensions, particularly in hydraulic power packs with  multi-pump sections.

The OT100, 200 & 300 Series are fully compliant with European Build Standards.

Available from our stock in the following sizes:

Group 1 (OT100) from 0,70 to 9,9 cc/rev

Group 2 (OT200) from 4,10 to 30cc/rev

Group 3 (OT300) from 22 to 60cc/rev

We also stock Helical Noise Reducing Pumps which are a popular choice among hydraulic power pack manufacturers who are looking for  substantially quieter pump operation while still getting optimal performance and reliability.

Noise reduction is a key area that manufacturers are always considering new measures to help quieten pump noise to counter the competition. The noise from a pump itself centres on the pulsating flow the pump creates with different style pump units creating different pitches in sound; for example from piston, vane and gear pumps.

Our Group 2 OT Cast Iron Gear Pump Range is suitable for Water Glycol based applications rated to 180bar and provides industry leading build quality and reliability. Meeting strict European European Standards Regulations, these pumps benefit from full cast iron construction and come with Viton seals and bronze bushes. Working to pressures of up to 300bar when used with standard hydraulic oils.The advantage these pumps have, working with a 40% water/60% Glycol fluid is that they can operate at a lower temperature than a typical application that uses an emulsion formula, thus leading to a much improved temperature/viscosity trait.

  • Why choose Hydraproducts as your component supplier?
  • Manufacturers

Hydraproducts has a large stock holding of components we are able to support irregular customer requirements. If you have regular needs then we are happy to hold bonded stock to smooth out production/supply fluctuations.

Supporting our customers with the comfort that our engineers have been using these components to build hydraulic systems in our own workshops for over 15 years. Our Technical Sales engineers can help and advise on product choice as well as identifiy and cross reference a wide variety of other hydraulic equipment manufacturers.

Key component suppliers 

OMT - Based in Italy, OMT has become a world recognized manufacturer of Hydraulic components. A recent acquisition of Luen, Hydraulic cartridge Valve manufacturer, has strengthened the group within mobile and industrial markets. 

OT - With a engineering pedigree in Italian gear pump manufacturing, this company produces some the of the finest Aluminium hydraulic Gear pumps available today. They are customer focused with a very reactive production philosophy.

TEC - Tec motors have become the largest reseller of AC induction motors in the  UK. Hydraproducts has fitted the TEC (TECHTOP) motors to our power packs and power units for over 15 years, so we know the quality is well suited to this market palce.

  • 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.
