5. Special Instructions for Double Pumps
-
Displacement Combination: The double pump consists of two independent pump cartridges, supporting free combination of different displacements (e.g. T7DBS-B42-B12 = 137.5+38.5 = 176 ml/rev).
-
Pressure Characteristics: The front and rear pumps can operate independently at different pressure levels, meeting the composite working conditions of high-pressure low-flow and low-pressure high-flow.
-
Mounting Direction: Standard direction (1R00) or reverse direction (1L00) is optional to adapt to different system layouts.
6. Application Scenarios
-
Industrial machine tool hydraulic systems
-
Multi-circuit hydraulic drive for injection molding machines and die-casting machines
-
Heavy-duty equipment such as presses, bending machines and shearing machines
-
Hydraulic units for automated production lines
-
Variable Speed Drive (VSD) hydraulic systems, compatible with variable frequency motor control
7. Key Feature Summary
-
High Pressure Performance: Continuous operating pressure up to 210-250 bar, intermittent pressure up to 240-280 bar.
-
Low Noise Design: Adopts Denison patented vane technology for low operation noise.
-
Long Service Life: Optimized vane and stator curve design reduces wear and prolongs service life.
-
Flexible Configuration: Various combinations of mounting flanges, shaft types, seals and displacements to adapt to diverse system requirements.
