hydraulic piston pump

hydraulic piston pump
Product Detailed
hydraulic piston pump decription: Size: 18-140 Nominal pressure: 280Bar Swash plate design axial variable piston pump

HWA10VSO hydraulic  piston pump description:

(1).Swash plate design axial variable piston pump used in open circuit.
(2).Continuous work pressure can reach 280bar,the highest instantaneous work pressure can reach 350bar.
(3).The flow is directly proportional to the drive rotate speed and the displatement,and can make stepless variable come true by adjusting the obliquity of the swash plate.
(4).Wide range of controls such as DR,DFLR etc.Short response times.
(5).Low noises level,High efficiency,High reliability and long time service life.
(6).Small volume,High power density.
(7).Excellent oil absorbency.
(8).Axial and radial loading of drive shaft possible.
(9).SAE and ISO mounting flange.

(10).Thru drive option for multi-circuit system

The HWWA10VSO variable displacement pump is suitable for use with mineral oil.

Operating viscosity rangeIn order to obtain optimum efficiency and service life, we recommend that the operating viscosity(at operating temperature) be selected from within the range.Vopt=operating viscosity16…36mm2/sReferred to the reservoir temperature(open circuit)

Viscosity limitsVmin=10mm2/s short term at a max. permissible drain of 90°C.Vmax=1000 mm2/s short term on cold start Temperature range(see selection diagram):t=-25~90°C

Note on the selection of the hydraulic fluid.In order to select the correct fluid, it is necessary to know the operating temperature in the tank (open loop) in relation to the ambient temperature.The hydraulic fluid should be selected so that within the operating temperature range, the operating viscosity lies within the optimum range(Vopt)(see shaded section of the selection diagram ).We recommend that the higher viscosity range should be chosen in each case.

FiltrationThe finer the filtration the better the cleanliness of the pressure fluid and the longer the life of the axial piston unit. To ensure the functioning of the axial piston unit a minimum cleanliness level of:9 to NAS 1638 18/15 to ISO/DIS4406 is necessary.
