T7DBS-E42-E15-1R11-A1 Parker Denison Double Vane Pump 187.5 cc 260 bar

Model 1: T7DBS-E42-E15-1R11-A1

Product Overview

The T7DBS-E42-E15-1R11-A1 is a Parker Denison T7DBS Series heavy-duty hydraulic double fixed displacement vane pump. This double pump configuration features a P1 (front pump) displacement of 137.5 cc/rev and a P2 (rear pump) displacement of 50.0 cc/rev, with a total displacement of 187.5 cc/rev and a maximum operating pressure of 260 bar.

The T7DBS Series belongs to the D-Series frame (medium-to-large displacement double pumps) within the T7 family, specifically engineered for hydraulic systems requiring two different pressure/flow combinations. The T7DBS features SAE J744 standard C-type 2-bolt mounting flange, compatible with SAE C standard drive shaft interfaces.

T7 Series variable speed vane pumps are especially dedicated to providing an ideal solution for modern servo controlled machines. When driven with asynchronous or synchronous electric motors and piloted by frequency controllers, they operate in the most efficient and reliable ways, allowing maximum energy savings.

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. Fully Pressure Balanced Concept
The T7 Series incorporates a fully pressure balanced design that extends pump life across the entire operating range. Double lip vanes reduce sensitivity to fluid contamination. This design ensures balanced internal forces under high-pressure operation, minimizing wear on critical components.

2. 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 0.93~0.94. The double lip geometry also enhances tolerance to particulate contamination, significantly improving pump reliability and service life.

3. Variable Speed Drive Optimization
The T7 Series is specifically designed for variable speed drive applications, offering a wide speed range of 600~3000 RPM. When paired with frequency-controlled motors, it enables up to 70% electrical energy savings while reducing noise emissions and total system costs.

4. Low Noise & Low Pressure Ripple
Denison Vane Technology allows very low noise levels over the entire operating range and during the whole life of the pump. Pressure ripple is as low as ±2 bar, with operating noise 3~5 dB(A) lower than conventional pumps.

5. Cartridge Kit Design & Flexible Configuration
Various pumping units (cartridge kits) can be combined with other pumping unit sizes in multiple pumps, creating a wide range of multi-flow pump configurations. 64 port position combinations are available to suit various system layouts. Multiple displacements are offered for the same installation size, enabling powerful and compact pump assemblies.

Application Areas

The T7DBS-E42-E15-1R11-A1 double vane pump is widely deployed across the following applications:

• Injection Molding Machines

• Die Casting Machines

• Oil Press / Hydraulic Presses

• Plastic Industrial Equipment

• Auto Industrial Equipment

• Variable Speed Drive Hydraulic Systems

Expert Maintenance Tips

1. 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.

2. Fluid Cleanliness: Maintain system fluid cleanliness to NAS Class 7 (ISO 4406 16/14/11) or better to maximize vane and cam ring service life. Install a 10 μm suction strainer.

3. Mounting Torque: For SAE C 2-bolt flange mounting, refer to Parker Service Manual (Bulletin HY29-0036-M1/UK) for specified torque values.

4. Rotation Confirmation: Verify pump rotation direction matches system requirements before installation. This model is configured for clockwise rotation (R: viewed from shaft end).

5. Variable Speed Operation: When used in variable speed drive systems, ensure frequency controller parameters match the pump’s speed range (600~3000 RPM). Minimum stable speed is approximately 400 RPM.

6. Temperature Control: Maintain fluid temperature within 15~60°C range, with maximum not exceeding 80°C.
