TRF Oil Line Hydraulic Suction-Return Filter from Heavy Machinery Hydraulic Accessories Wholesaler

1.Product introduction

TRF suction-return filters are used for hydrostatic transmission, under all the motion conditions, when the flow rate of return oil is always higher than the flow rate of the hydraulic pump output.

Through full-flow filtration of filter element, meet the highest cleanliness rating requirements. The product is suction-return oil filtration in one, can filter the suction oil completely,

so that contaminants cannot enter the hydraulic pump. Through the full-flow filtration of the system return oil line, protecting the hydraulic pump from particles contamination.

2.Product characteristics

Filter basic construction

TRF series filters consist of the housing and filter element, also has check valve (0.5bar), two-way ball valve with transparent hose, filter element, pressure safety valve (2.5bar), emergency suction valve for protecting filter element, pressure control valve (0.5bar), oil returning port, suction oil mouth of supply pump, pressure clogging indicator port, and vacuum clogging indicator port etc.

2.1 Housing material

Housing material: steel and aluminum alloy

Filter cover: Aluminum alloy

2.2 Seals

Perbunan (= NBR) ; Viton (= FPM)

2.3 Filter element

Filter medium material

High strength carbon steel skeleton

2.4 Type of connection

3. Type selection and technical data

3.1 Technical Data

Note: * represents filtration rating.

All the filters have M12 x 1.5 additional interface and plug. Pressure gauge or pressure switch can both be used for clogging alarm of oil return side.

Oil suction side can also be added vacuum switch for monitoring.

4. Mounting Size

Note: Outlet port and emergency suction port must be below the minimum level under all the operating conditions (see Y value)

5. Product characteristic curves

The total filter assembly pressure drop is the sum of housing and element pressure drop,filter selection calculated as per the following curves.

♦ Filter differential pressure characteristics curves listed on the third column of type selection table.
