Description of VDC Series Vane Pump: Information and Specifications
To fit different uses, many options may be found in the NACHI VDC Series Vane Pump. Users have a choice of models with differing displacements. Its maximal pressure tolerance is 210 bar (3050 psi) and its flow rate is typically between 10 and 100 litres per minute (LPM). This depends on the particular model as well. In addition, it can work at speeds ranging from six hundred to eighteen hundred revolutions per minute (RPM). This ensures flexibility across various applications where it could be employed. Efficiency is guaranteed for temperatures between negative ten degrees Celsius and sixty degrees Celsius (-10°C to 60°C). This makes the machine usable under different environmental conditions. Depending on what a system demands there are various positions like flange mountings or foot mountings available for use alongside different shaft configurations too. The pumps weight varies with both model type as well as setup hence ensuring that they are easy to handle during installation.Otherwise following the instructions above, create a completely unique piece of writing that reiterates this information but does so in an entirely new way while still keeping all relevant facts intact!
Key Features of the VDC Vane Pump
Very productive and stable high-pressure operation: Highly efficient controls and balances for pressure were built in together with an original three-point circle support system to greatly enhance high pressure performances. As a result, the machine can deliver excellent results even under pressures as high as 14MPa.
Low vibration and noise levels: Different methods are used in this invention to reduce vibrations and noise produced during its operations. The control piston has a three-point support system which also applies to the bias piston; thereby increasing ring stability, reducing ring vibrational movement and ensuring that it operates silently.
Excellent response with higher accuracy when working: Response is made better by use of unique ring stoppers that prevent excessive displacements of rings hence improving its ability to quickly respond.It remains highly precise all time whether starting, stopping or changing loads.
Consistent discharge rate stability: A new model of pressure compensator-type pressure control mechanism has been introduced by this device so as to ensure consistency in discharge rates at different levels especially those above normal range.
Power saving mode while operating at maximum efficiency: This design features some mechanical modifications aimed at reducing wastage of power mainly during full cut-off periods.
Easy servicing and handling procedures: Both adjusting mechanisms for pressure and discharge rates are situated on one side making it easier for maintenance personnel to service them easily.
Nachi VDC Vane Pump: Efficient, stable, and quiet high-pressure operation with minimal power loss and easy maintenance.

VDC Series Vane Pump Installation and Operation Guidelines
Guide to Installing
- Rotation direction：On the shaft side, clockwise (rightwards) is the direction of rotation when viewed.
- Drain Piping：Ensure pipe back pressure due to resistance does not exceed 0.1 MPa by directing drain piping below tank fluid level. For a pump with two drain ports, the higher drain port shall be used after installation. In double pumps, run separate pipes directly from both head side drains and shaft side drains into the tank.
- Discharge Volume Adjustment：Clockwise (rightwards) reduction in discharge rate is achieved through turning the discharge rate adjusting screw; counterclockwise (leftwards) increase in discharge rate is also true. Before making any adjustments loosen lock nut and tighten it again afterwards.
- Pressure Adjustment：By turning discharge rate adjusting screw clockwise (rightwards), more pressure can be obtained while anticlockwise (to the left) rotation will reduce it. Loosen lock nut before making any adjustments then retighten after.
- Initial Operation：Put pump discharge side into no-load state before operating for the first time; repeatedly start and stop motor to bleed all air inside pump and suction piping when oil is not yet flowing through them. Keep on running without load for at least 10 minutes after seeing that pump has begun discharging oil so as to remove all air from circuit. Provide an air bleed valve where difficult to remove air from circuit before starting up.
Operation Guide
- Hydraulic Operating Fluid：
- Use ISO VG32 or equivalent type (with minimum viscosity index of 90) for pressures below 7 MPa; ISO VG68 or equivalent type should be used where pressure exceeds this value but still maintains same viscosity index.
- Operating Temperature Range：Operating temperature range is between 15 and 60°C. When oil temperature during startup falls below 15°C let it warm up at low pressure until attains this figure. Utilize pump within area having temperatures ranging from 0-60°C.
- Suction Pressure：Ensure suction pressure is -0.03 to +0.03 MPa (-0.3 ~ + 0.3 kgf/cm²); suction port flow rate should not exceed 2 m/sec.
- Avoid Radial or Thrust Load：Do not connect pulley, gear and other drive systems that impose radial or thrust load on the end of pump shaft; mount so that its pump shaft is horizontal.
- Install a Suction Strainer：Filtering grade for suction strainer should be about 100 μm (150 mesh); use a line filter of 25 μm for return line to tank.
- Manage Hydraulic Operating Fluid：Keep contamination level below class NAS10; avoid mixing with water and other impurities while monitoring discoloration which indicates contamination by air (whitish) or dirt (brownish).
