4 Introduction With thru drive for single and multiple pumps wash plate type for open circuit xial iston umps eries Vplus echnical Features Low noise level Fast response ervice-friendly High self-priming speed Compact design hru drive for 1% nominal torque General Information Fluid recommendations remium quality hydraulic mineral fluid is recommended, like HL oils to DIN 51524, part 2. Brugger- value has to be 3 N/mm 2 minimum for general application and 5 N/mm 2 for heavily loaded hydraulic equipment and fast cycling machines and/or high dynamic loads, measured in accordance with DIN ee also Document HY3-3248/UK arker Hydraulic Fluids. Viscosity he normal operating viscosity should range between 16 and 1 mm 2 /s (ct). Max. start-up viscosity is 8 mm 2 /s (ct). Filtration For maximum pump and system component functionality and life, the system should be protected from contamination by effective filtration. Fluid cleanliness should be in accordance with IO classification IO 446:1999. he quality of filter elements should be in accordance with IO standards. General hydraulic systems for satisfactory operation: Class 2/18/15, according to IO 446:1999 Recommended cleanliness for maximum component life and functionality: Class 18/16/13, according to IO 446:1999 eals Check hydraulic fluid specification for chemical resistance of seal material. Check temperature range of seal material and compare with max. system and ambient temperature. N Nitrile (FKM shaft seal) C B Nitrile (NBR shaft seal) C V FKM (FKM shaft seal) C W Nitrile (FE shaft seal) C FKM (FE shaft seal) C Note: he highest fluid temperature will be at the drain port of the pump, up to 25 C higher than in the reservoir. 4 arker Hannifin ump & Motor Division Europe
