E 084 • Tank top mounting • Connection up to G1 • Nominal flow rate up to 80 l/min

Description Application For operation in units with hydrostatic drives, when the return flow is under all operating conditions higher than the oil flow of the boost pump. Performance features Protection against wear: By means of filter elements that, in full-flow filtration, meet even the highest demands regarding cleanliness classes. Suction filter function: Because of the 100%-filtration of the suction flow, no dirt can get into the boost pump. Return filter function: By means of full-flow filtration in the system return, the pumps above all are protected from dirt particles remaining in the system...

Layout General In machines with a hydrostatic drive and combined working hydraulic system, suction-return filters replace the suction or pressure filters previously required for the feed pump of the closed-loop hydrostatic drive circuit as well as the return filter for the open-loop working hydraulic circuit. While each circuit operates independently with separate filters, the combination of the two circuits via the suction-return filter causes interaction between the circuits. If the design criteria described below are taken into account, you can take full advantage of the benefits provided by...

Characteristics Nominal flow rate Up to 80 l/min in return line (see Selection Chart, column 2) Up to 40 l/min Feed pump flow rate (see Layout) The nominal flow rates indicated by ARGO-HYTOS are based on the following features: • closed by-pass valve at ν ≤ 200 mm2/s • element service life > 1000 operating hours at an average fluid contamination of 0,07 g per l/min flow volume • flow velocity in the return lines ≤ 4,5 m/s • flow velocity in the suction lines ≤ 1,5 m/s Viscosity at nominal flow rate • at operating temperature: ν < 60 mm2/s • as starting viscosity: νmax = 1000 mm2/s • at first...
