BD Series HIGH PRESSURE VANE PUMPS

Product catalog summary

Company Overview: jbj Techniques Limited specializes in mechanical power transmission and fluid power solutions, offering design engineering, product supply, and after-sales service. They are known for their expertise in hydraulic and mechanical transmission systems, providing customized solutions.

Product Range: The company offers a wide range of products including couplings, gearboxes, clutches, pumps, hydraulic motors, and fluid power accessories. Their gear coupling portfolio includes 14 designs and 22 styles.

Hydraulic Vane Pumps: The BD series of high-pressure hydraulic vane pumps are noted for their versatility, power, compactness, and low running costs. Key features include easy maintenance through a cartridge unit, a rotor driven by a splined shaft, and a design that minimizes radial loads on shaft bearings.

Specifications: The BD series pumps are available in single and double versions, with capacities from 10 to 385 l/min at 1000 rpm. They are designed for high-pressure applications with low noise emissions and compatibility with various hydraulic fluids.

Technical Details: Operating with a viscosity range of 10 to 2000 cSt, the pumps require filtration to maintain contamination levels to ISO 18/14 standards. They are suitable for a range of operating temperatures depending on the fluid type.

Installation and Maintenance: The pumps are compact, easy to install, and interchangeable with similar models. They feature a cartridge design for quick inspection and replacement of wear components without disconnecting the pump from the circuit.

Operating Conditions: Minimum inlet pressure with mineral oil is 0.8 bar abs. Operating temperature varies with fluid type, and during cold start, pumps should operate at low speed and pressure until fluid warms up.

Performance Data: Detailed performance data includes rated capacity, maximum pressure, geometric displacement, and speed range. For example, the BD05 series offers displacements from 214 to 341 l/min at 1500 rpm.

Fluid and Filtration Requirements: Compatible with antiwear petroleum base, synthetic fluid, water glycols, and invert emulsions. Recommended viscosity is 30 cSt for maximum lifetime, with filtration to ISO 18/14 or NAS 1638 class 8.

Torque and Load Specifications: Includes calculations for maximum permitted torque and allowable radial and axial loads, specifying spline codes and dimensions for shaft options.

Model Code Breakdown: Provides a breakdown of model codes, including cartridge model, port orientations, seals, rotation, and shaft end options.

Graphical Data: Graphs illustrate the relationship between pressure, speed, and fluid type, as well as noise levels, power loss, and internal leakage.

Recommendations: For maximum pump lifetime, maintain a viscosity of 30 cSt and ensure filtration to ISO 18/14 or NAS 1638 class 8.

Installation Guidelines: Fluid velocity should be between 0.5 and 1.9 m/sec. The inlet line must be hermetically sealed to prevent air entrainment. Filters should be replaced after the first 50 hours and then every 500 hours.

Start-up Procedure: Fill the pump and inlet line with fluid, start the motor at low speed intermittently until noise reduces, and check outlet pressure. Maintain low pressure until air bubbles are eliminated.

Cold Starting: Operate the pump at moderate speed and pressure in low temperatures until the circuit reaches the correct temperature.

Vertical Installation: The pump cannot operate vertically unless equipped with devices to fill it completely before each start.

Company Information: JBJ Techniques Limited is ISO certified and offers ATEX certified products, located in Redhill, Surrey, UK.

Versatility, power, compactness and low running costs are the main characteristics of vane pumps from jbj Techniques Limited All the components subject to wear are contained in a cartridge unit that can be easily removed for inspection and/or replacement without disconnecting the pump from the circuit, drastically reducing expensive machine down time. The cartridge contains a rotor, vanes and inserts, a cam ring and two covers. During operation the rotor is driven by a splined shaft coupled to the drive unit. As the rotation speed increases, centrifugal forces, in combination with the pressure...
