The Tokimec SQP series hydraulic vane pumps feature low noise and are offered in 4 frame sizes, 16 series, 32 models of different displacements and as triple pump which allow user to select the combination which best matches their circuit for optimum energy efficiency.
1. Offers very quiet and soft operational noise levels.
2. Multiple pump combinations of differing displacements permits simpler circuit designs compared to system using one large displacement pump and provide greater flexibility in circuit design with benefit of low noise levels.
3. Rotation element is in pump cartridge kit from which allows simple maintenance.
  
Tokimec SQP vane pump is developed to meet the increasing demands of machine tool industry. Total 4 series including 19 kinds are available, whose displacement ranges from 18 ml/r to 193. ml/r, max continuous operating pressure is 17.2 MPa, the speed of rotation ranges from 600 rpm to 1800 rpm. The intra-vane structure ensure many good characteristics such as high pressure, large capacity, small volume, smooth operation, low noise, efficient capacity efficiency and long service life etc. The main technical data has reached an advanced level in the international market of the same trade.
This series of pump is composed of replaceable cartridge kits, which reduce the construction time thus enhance production efficiency. Optimum design of pump core further reduce the pressure shimmy, flow pulsation and noise of the pump, sound pressure balance which compensate the space can have better capacity efficiency. The proper design of oil supply system between vane and intra-vane enables good contact between blade and stator and ensure minimum flow loss. The unique design, high-precision processing and rational material selections prolong the service life of the pump. With complete specifications, reliable performance, simple and rational structure, convenient installation and repairing (the connection complies with ISO and SAE), the pump is widely used in machine-tool, press and die casting machines, engineering, plastic injection molding and other machineries. 
  
Application and maintenance:
Start maintenance 
1. Before starting pump, please check up if the inlet and outlet have been correctly connected and the rotation of the pump is inline with the nameplate.
2. After confirming that it is able to work well without burden, please start. 
3. When initially starting the pump after long- time unused, removing all trapped air from system can be accomplished by loosening flange or connections. 
4. PIease inject rust-proof oil in the pump, paint the surface with rust-proof grease and then cover ports, if you do not want to use it immediately. 
5. Please check up oil periodically, if the oil cannot meet the demand, replace it and clean up tank. 6. Purging of filter regular is recommended. 
7. Keep the normal level of oil in the tank. When capability of tubing and tank are large, even if injected enough oil. Because when starting, the level of oil would fall, then please add some oil observe the level of oil and add some oil when needed. 
8. After a period of working, it is likely that the installing bolt and flange of inlet and outlet would lose because of vibrating, and tighten them. 
9. The SQP vane pump cartridge design of hydraulic vane pumps offers fasten efficient field service ability, when replacing the cartridge, 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. 
Recommendations:
Important Factors in Selecting Oil Additives--The oil in a hydraulic system serve as the power transmission medium. It is also the system’s lubricant and coolant. Selection of the proper oil is a requirement for satisfactory system performance and life. Hydraulic fluids contain a number of additive agents which materially improve various characteristics of oil for hydraulic systems. These additives are selected to reduce wear, increase chemical stability, inhibit corrosion and doers the pour point. Pump performance and reliability and directly affected by the anti-wear additive formulation contained in the oil .Oils providing a high level of anti-wear protection are recommended for optimum performance and long life.
