Products Specifications:

Vane Pump in Series SQP

■General Description
SQP series intra-vane pump having high pressure and low sound are developed to meet the application of industry. Total 4 series and 34 sizes are available. Intra-vane design enables the pump having high pressure, large capacity, compact size, low sound level and longer service life features, its main technical data have reached to the advanced level of the same product in the world.

With complete specifications, reliable performance, reasonable construction and convenient installation and easy maintenance, it is widely used in hydraulic systems for machine-tools pressure, die casting machines, engineering,plastic injection moulding and other machineries.Main characteristics:
1.The pump cartridge of SQP can change with that of Vickers series intra-vane pump.
2.It can replace the pump cartridge to change displacement.
3.Strengthened pump housing design offers a better anti-vibration ability,which effect the remarkable low noise.

Installation and Application

1.Operating oil
①Anti-wear hydraulic oil is recommended. It's viscosity range: 10~100cSt(1.8-13°E),recommended viscosity 24cSt(50℃).
②Filtration: the filtration rating shouldn't be lower than 25μm, a filter with filtration rating of 70~150μm should be fitted at inlet port and its rated flow more than twice of that of the pump.
③Temperature range: ambient temperature -20~+70℃; operating temperature +10~+60℃.
④Fire resistance fluid: special seal should be used when using fire resistance fluid; for rated pressure and max. speed of the pump,refer to that in the main performance data table.

2.Installation
①Foot and frame for pump must be reliable, solid and good in vibration absorbance.
②Horizontal mounting is recommended to maintain necessary case fluid level. Concentricity of shafts between pump and motor is important to pump life and should be within Ø0.1mm.Radial or axial load can't be applied on pump shaft and a flexible coupling should be used and rigid linkage not permitted.
③To reduce noise and vibration of system caused by trapped air, attachment flange at inlet port, all fittings and pipelines must be strictly sealed.
④Before starting the pump, you should check if the inlet and outlet have been correctly connected and the rotation of the pump is in the line with the arrow in the nameplate. To prevent the pump from cavitation caused by the first starting or stopping run for a longer time, air should be bled from the pump delivery line. This may be accomplished by loosening a connection in the delivery line close to the pump. An air bleed valve is available for this purpose. When starting, the pump should be repeatedly jogged without any load. After the pump may normally run, it can be actually primed.
⑤Suction lift of pump shouldn't be higher than 500mm.

3.Replacing cartridge kit
The cartridge kit design of SQP series vane pumps offers fast and efficient field serviceability.
When replacing the cartridge kit, seals inside the pump should be checked to avoid them crimping;
when tightening the fastening screws, they should be treated with even force in diagonal direction.
