Product Overview
The T7BBS-B02-B02-1R00-A1M1 is a Parker Denison T7BBS Series heavy-duty hydraulic double fixed displacement vane pump. This double pump configuration features a P1 (shaft-end/front pump) displacement of 5.8 ml/rev and a P2 (cover-end/rear pump) displacement of 5.8 ml/rev. The T7BBS Series incorporates Parker’s patented double lip vane technology, delivering exceptional contamination resistance and reliability.
The T7BBS Series double vane pump combines two independent pump cartridges within a single housing, sharing a common drive shaft to deliver two distinct pressure/flow outputs for complex hydraulic circuit requirements. The B02 displacement represents the smallest displacement option in this series, making it ideal for precision hydraulic applications requiring accurate flow control and modest system power.
As a premium aftermarket alternative to original Parker Denison hydraulic pumps, this product offers 100% direct interchangeability with identical mounting dimensions and performance specifications, requiring zero modification to existing systems.
Every unit undergoes 100% simulated duty cycle testing prior to shipment, guaranteeing performance reliability under actual working conditions.

Key Technical Advantages
1. Double Lip Vane Technology
Parker’s patented double lip vane design achieves superior sealing between vanes and the cam ring inner surface, delivering high volumetric efficiency — typically 94%. The double lip geometry also enhances tolerance to particulate contamination, significantly improving pump reliability and service life.
2. Full Pressure Balance Design
The T7BBS Series incorporates a full pressure balance design that effectively extends pump service life. This design ensures balanced internal forces under high-pressure operation (up to 320 bar intermittent), minimizing wear on critical components.
3. Compact Double Pump Configuration
The double pump design allows two independent cartridges (P1 and P2) within a single housing, delivering two distinct pressure/flow outputs. The B02-B02 combination is ideal for applications requiring dual-circuit precision low-flow output, dramatically simplifying hydraulic circuitry and saving installation space.
4. Low Noise & Wide Speed Range
Denison vane technology ensures consistently low noise levels across the entire operating range. With a wide speed range of 600 – 3600 rpm, the pump adapts flexibly to diverse operating conditions.
5. Cartridge Design & Flexible Installation
The cartridge-style pump core design enables rapid cartridge replacement, significantly reducing downtime. The double pump offers 32 mounting positions for optimized system layout and reduced installation costs.
Application Areas
The T7BBS-B02-B02-1R00-A1M1 double vane pump is widely deployed across the following applications:
Injection Molding Machines — dual-circuit independent control
Machine Tool Hydraulics — precision feed control
Industrial Automation Equipment
Lubrication Systems
Servo Hydraulic Systems
Material Handling Equipment
Expert Maintenance Tips
Pre-Start Priming: Prior to initial start-up, fill the pump housing with hydraulic fluid through the drain port to ensure adequate lubrication of internal components.
Fluid Cleanliness: Maintain system fluid cleanliness to ISO 4406 18/16/13 or better to maximize vane and cam ring service life. Install a suction strainer with filtration accuracy of 30 mesh/inch or finer.
Rotation Confirmation: Verify that pump rotation direction matches system requirements before installation. This model is configured for clockwise rotation (R: Right Hand viewed from shaft end).
Piping Installation: Clean pipe interiors thoroughly before installation. Ensure piping weight is not supported by the pump to maintain precision and service life.
Operational Monitoring: Install vacuum and pressure gauges on inlet and outlet lines to monitor pump operating status. If abnormal noise or excessive temperature rise occurs, shut down immediately for inspection.
Seal Compatibility: This model is equipped with BUNA N standard seals (M1), suitable for mineral oil media. For fire-resistant fluids, select appropriate seal classes such as EPDM or Viton®.
