Fluid recommendations remium quality hydraulic mineral oil fluids are recommended, like H- oils to DIN 51524, part2. he viscosity range should be 25 to 50 mm²/s (ct) at 50º C. Operating temperatures 10 to +70ºC. For other fluids such as phosphoric acid esters or for other operating conditions, please consult with YEOHE for assistance. B. eals NBR (Nitrile) seals are used for operation with hydraulic fluids based on mineral oil. For synthetic fluid, as perhaps phosphoric acid esters, Fluorocarbon seals are required. lease consult with YEOHE for assistance. C. Filtration For maximum pump and system component functionability and life, the system should be protected from contamination by effective filtration. Fluid cleanliness should be in accordance with IO classification IO he quality of filter elements should be in accordance with IO standards. (1) inimum requirement for filtration rate (mm): General hydraulic systems for satisfactory operation: Class 19/15, to IO 4406 X=25m (2575) to IO 4572 (2) Hydraulic systems with maximum component life and functionability: Class 16/13, to IO 4406 X=10m (1075) to IO 4572 It is recommended to use return line or pressure filters. YEOHE Filter Division offers a wide range of these filters for all common applications and mounting styles. he use of suction filters should be avoided, especially with fast response pumps. Bypass filtration is a good choice for best filter efficiency. D. Installation and mounting Horizontal mounting: Outlet port-side or top. Inlet port-side or bottom, drain port always uppermost. Vertical mounting: haft pointing upwards. Install pump and suction line in such way that the maximum inlet vacuum never exceeds 0.8 bar absolute. he inlet line should be as short and as straight as possible. short suction line cut to 45º is recommended when the pump is mounted inside the reservoir, to improve the inlet conditions. ll connections should be leak-free, otherwise the air in the suction line will cause cavitations, noise, and damage to the pump. E. haft rotation and alignment ump and motor shafts must be aligned within 0.25mm.I.R. maximum. floating coupling must be used. Bellhousings and couplings can be ordered at manufacturers listed in this catalog. lease follow the coupling manufacturer s installation instructions. lease consult with YEOHE for assistance on radial load type drives. F. tart up rior to start up, the pump case must be filled with hydraulic fluid (use case drain port). Initial start up should be at zero pressure with an open circuit to enable the pump to prime. ressure should only be increased once the pump has been fully primed. ttention: Check motor rotation direction. 26

56 V xial iston ump GENER INION INFORION G. Operating noise of pumps he normal operating noise of a pump and constantly-operation noise of the entire hydraulic system is largely determined by where and how the pump is mounted and how it is connected to the down stream hydraulic system. Besides, size, style, and installation of hydraulic tube are the major influence on the overall noise emitted by a hydraulic system. H. Noise reduction measures Flexible elements help to prevent pump body vibration from being transmitted to other construction elements, where amplification may occur. uch elements can be: Bell housing with elastic dampening flange with vulcanized labyrinth (1) Floating and flexible coupling (2) Damping rails (3) Or silent blocks for mounting the electric motor or the foot mounting flange (4) Flexible tube connections (compensators) or hoses on inlet, outlet, and drain 2 1 port of the pump. (5) Exclusive use of gas tight tube fittings for inlet connections to avoid ingression of air causing cavitations and excessive noise. I. Drain line he drain line must lead directly to the reservoir without restriction. he drain line must not be connected to any other return line. he end of the drain line must be below the lowest fluid level in the reservoir and as far away as possible from the pump inlet line. his ensures that the pump is not empty itself when it s not in operation and the hot aireated oil will not be recirculated. For the same reason, when the pump is mounted inside the reservoir, the drain line should be arranged in such a way that a siphon is created. his ensures that the pump is always filled with fluid. he drain pressure must not exceed 1 bar. Drain line length should not exceed 2 meters. inimum diameter should be selected according to the port size and a straight low pressure fitting with maximized bore should be used. 3 V016~V023 V032~V046 V063~V092 V140~V180 V270 ize of pipe joints 3/8(8.5 or more) 1/2(12 or more) 3/4(16 or more) 1(19 or more) 1-1/4(22 or more) I.D. of pipes 12 more 15 more 19 more 25 more 32 more ength of drain Under 1m Under 1m Under 1m Under 1m Under 1m
