T7DD
Denison
| Product Introduction
The T7DD-B22-B14-1R00-A5 M0 is a dual hydraulic vane pump engineered for sustained high-pressure operation. Specifically developed for demanding industrial environments, this unit delivers robust performance in applications including metalworking machinery, plastic injection molding presses, industrial stamping systems, and die-casting equipment.
Its modular cartridge kit integrates critical components:
1.Rotor and cam ring assembly
2.Double-lip vane kits
3.Precision balancing plates
Configurable cartridge combinations in dual-pump setups enable two distinct operational modes:
1.High-pressure/low-flow output (up to 300 bar)
2.High-flow/low-pressure delivery
3.This flexible architecture optimizes hydraulic circuit design by matching performance to application requirements.
Additional advantages include:
1.Rapid pressure cycling capability
2.Exceptional flow repeatability (±0.5% typical)
These characteristics make the pump particularly suitable for press machinery where dynamic response and precision are critical.
| Packaging And Delivery
Supported shipping modalities:
Maritime shipping (Full Container Load/Less than Container Load)
Transcontinental rail
Airfreight (IATA-compliant)
Priority courier services (DHL/UPS/FedEx)
|SPECIFICATION
The double or triple pump combine two or three cartridge kit together, so to calculate the displacement of the pump, simply we can sum the displacement of each catridge. For example, T7DD-B22-B14 is the combination of B22 catridge and B14 combination, the displacement is 70.3 plus 44.0 equal 114.3mL/r according to the excel.
