Parker Denison T7DDB/T7DDBS Series Vane Pumps
1. Overview
2. Core Features
-
High Pressure Capacity: The maximum operating pressure can reach 300 bar, with a peak pressure of up to 280 bar for intermittent operation, making them suitable for medium and high-pressure hydraulic systems. Reducing the operating pressure appropriately can further extend the service life of the pump.
-
Low Noise Operation: Adopting optimized vane structure and hydraulic design, the pumps maintain low noise levels throughout the entire operating range, significantly improving the working environment.
-
Superior Contamination Resistance: Equipped with double-lip structure vanes, the pumps exhibit strong resistance to oil contamination, reducing wear and tear and ensuring stable operation even in harsh working conditions.
-
Wide Speed Range: The recommended operating speed range is 600-3000 rpm, allowing flexible matching with different motors to optimize system working conditions and energy consumption.
-
Broad Viscosity Adaptability: Capable of operating with hydraulic media of various viscosities, enabling smooth startup at low temperatures and stable operation at high temperatures.
-
High Volumetric Efficiency: Advanced structural design minimizes internal leakage, improving energy utilization, reducing heat generation, and lowering the overall operating cost of hydraulic equipment.

4. Model Code Interpretation
-
T7: Series code, indicating Denison T7 series vane pump.
-
DDB/DDBS: Structure type code. DDB represents single-section vane pump; DDBS represents double-section vane pump (capable of independent dual flow output).
-
050/B22/B12: Displacement code, corresponding to specific theoretical displacement (unit: ml/rev).
-
1R00: Mounting and shaft end code. “1R” indicates right-hand rotation shaft end; “00” represents standard mounting flange and oil port configuration.
-
A1M0: Control mode code, indicating fixed displacement mode with standard configuration.
5. Application Fields
-
Injection molding machines and die-casting machines
-
Construction machinery (such as loaders, rollers, concrete pump trucks)
-
Machine tools and hydraulic stations
-
Marine machinery and mining equipment
-
Heavy-duty hydraulic systems requiring multi-actuator linkage
6. Installation & Maintenance Notes
-
Ensure accurate alignment between the pump shaft and the motor to avoid excessive radial force, which may cause shaft wear.
-
Use a filter with 10μm precision in the hydraulic system to prevent oil contamination from damaging vanes and other components.
-
Regularly inspect the clearance between vanes and stators. Replace wearing parts when the leakage exceeds 15% of the rated value.
-
Verify the complete model code before selection to ensure consistency with system pressure, flow, and mounting requirements.
-
The oil port can be configured on the side or tail, facilitating flexible installation in different equipment layouts.
