Return Filters

Common in most hydraulic systems, return line filters offer a reliable & effective way of preventing contamination generated in the system from entering the hydraulic reservoir. They are available in a variety of designs, mainly either mounted on the tank lid or in-line on the return side of the system.

Tank top return filters are available from stock with BSP ports as standard, other threads are available on request. The OMTF series has the return port on the head above the tank lid & the AFR series has a lower profile head with the return port located below the tank lid for applications where tank size & space is a premium. The OMTP series is similar to the OMTF but also has the addition of an integral air breather on the side of the head to prevent ingress of contamination from the environment.

The AFI series is particularly suitable for industrial use with a working pressure of up to 20 bar, it has a wide range with flow capability up to 1200l/min 2 designs of spin-on return filters are available. 

The OMTI series is mounted in-line with options of double cannister heads for higher flow applications & the FTT series is a tank top mounted filter which utilises the bypass valve inside the cannister.

Elements are available in inorganic glass fibre (3,6,10 & 25 micron absolute), resin impregnated paper (10 & 25 micron nominal) & wire mesh (25,60 & 90 micron).

All ranges are available with visual or electrical indicators. Filters are fitted with NBR nitrile seals as standard, please consult our technical team for applications with fluids that require alternative seal compounds.

  • 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.
