Product Description
Parker Hydraulic Pump T6CC T7EDS T7GB T6DC T6ED T6EC T6CCW T67CB Series T7EDS 052 B38 2R00 A100 Variable Vane Pump
Displacement: The specific displacement needs to be further determined based on the product sample. The displacement range of the T7 series vane pumps is usually quite wide, and different models correspond to different displacements.
Pressure: The rated pressure can generally reach around 21MPa, and the maximum pressure may reach 28MPa. The specific values may vary slightly depending on the manufacturer and product design.
Rotational speed: The rotational speed range is typically 600-3600/min, capable of adapting to a relatively wide range of rotational speed operating conditions.2. Working Principle
The vane pump is mainly composed of a stator, rotor, vanes, oil distribution plate and transmission shaft, etc. When the rotor is driven to rotate by the motor, the blades are thrown out under the action of centrifugal force and bottom pressure oil, closely adhering to the inner wall of the stator. Under the eccentric effect of the rotor and stator, the volume of the sealed working chamber between adjacent blades gradually increases, forming a local vacuum. The external atmospheric pressure then injects the oil in the oil tank into the suction port of the pump, completing the oil suction process. As the rotor continues to rotate, the sealed cavity enters the oil discharge area. The inner wall of the stator gradually approaches the center of the rotor, causing the volume inside the cavity to continuously decrease. The oil is compressed and the pressure rises. When the pressure exceeds the pressure in the outlet pipeline, the high-pressure oil is forcibly discharged through the oil discharge port of the oil distribution plate, completing the oil compression process. The rotor keeps rotating, and the sealed cavities between the blades successively undergo the processes of oil suction, sealing, oil pressure, and sealing, thus achieving continuous oil suction and discharge.
3. Product features and advantages
Pressure balance design: By adopting the concept of pressure balance, the service life of the pump is prolonged. The radial and axial balance design effectively extends the service life of the bearings, reduces mechanical losses and noise levels of the pump.
Strong anti-pollution ability: The double-lip blade design enhances the resistance to solid particle contamination, enabling it to adapt to a certain degree of oil contamination environment, reducing the wear of blades and other components, and extending the service life of the pump.
Low noise: Dension blade technology allows for an extremely low noise level, generating little noise during operation and providing better noise control for the working environment.
Versatility and compactness: Under the same installation dimensions, it has multiple displacement specifications, which can meet the requirements of different working conditions. Moreover, it has a compact structure, occupies a small space, and can also be combined with pumps of other specifications to form a double vane pump.
Stable flow: It can meet the requirements of extremely rapid pressure change cycles, and the output flow can maintain precise repeatability, providing a stable flow supply for the hydraulic system.
4. Usage functions and purposes
Function of use: Convert the mechanical energy of the prime mover into hydraulic energy, provide pressure oil for the hydraulic system, drive the hydraulic actuating elements (such as hydraulic cylinders, hydraulic motors, etc.) to work, and achieve linear or rotational motion.
Application: Widely used in situations requiring hydraulic power, such as plastic machinery, die-casting machinery, metallurgical machinery, oil refining machinery, pressure machinery, construction machinery and Marine machinery, etc., providing power support for the hydraulic systems of these devices to achieve various actions and functions.
5. Applicable machines and scenarios
Applicable machines: It is particularly suitable for injection molding machines, die-casting machines, hydraulic presses and other machines with high requirements for pressure and flow changes, and can also be used in the hydraulic systems of machine tools and ships, etc.
Applicable scenarios: It is suitable for industrial scenarios that require high-pressure and high-performance hydraulic power, such as on factory production lines, providing stable hydraulic power for various processing equipment to ensure the smooth progress of production.
Other models in the T7 series, such as the T7B and T7D series of vane pumps, share certain similarities with the T7EDS in structure and performance. They all feature high pressure and efficiency, and can be selected based on specific requirements such as displacement and pressure.

7. Precautions for Use
Installation aspect: The oil pump should adopt coaxial drive. The coaxiality of the oil pump shaft and the drive shaft must be controlled within 0.2 millimeters. Elastic couplings must be used, and the holes of the couplings need to be machined to ISOH7 grade hole tolerance.
Oil pipe connection: The inner diameters of all rigid and flexible pipes must be thoroughly cleaned. The ends of the oil suction, return or drain pipelines must be located below the oil level in the oil tank.
Oil absorption conditions The suction inlet height of the oil pump installation should not exceed 0.5 meters above the oil level line of the oil tank. The suction pipe should be connected flexibly. The suction inlet pressure of the oil pump should not be lower than 0.8bar (relative pressure -0.2bar). The suction pipe line should be as short as possible with few elbows, and a pipe joint that can match the largest hose diameter should be selected for connection with the pump suction inlet. Each interface of the oil suction pipeline above the oil surface must be well sealed to ensure no air leakage.
Selection of working fluid: Petroleum-based hydraulic oil with a viscosity of 10-65mm²/s should be used. Anti-wear hydraulic oil is recommended. For other working fluids such as flame-retardant hydraulic oil, refer to the product sample table or consult the manufacturer.
Filtration requirements: The cleanliness grade of the working fluid should be maintained at NAS16238 level 8 (or ISO18/14). The hydraulic system must be equipped with a 25-micron grade oil filter, but it is not recommended to install an oil suction filter to avoid cavitation damage.
Initial startup: Check that the working fluid injected into the oil tank exceeds the height of the oil level line on the liquid level gauge. Check the rotation direction of the drive motor, which should be the same as the arrow direction on the oil pump nameplate. Make sure the suction inlet of the oil pump is facing upwards. Inject the working fluid into the pump and then connect the oil outlet pipe. Before the oil pump supplies oil to the system, the air inside the pump must be expelled.
Operation monitoring: After startup, pay close attention to the operating status of the pump, such as whether there are any abnormal noises, vibrations, overheating, etc. If any abnormalities are found, stop the machine in time for inspection.
