Overview

This document details JBJ Techniques Ltd's vane pump product range, highlighting technical specifications, performance data, shaft dimensions, installation options, and maintenance features. The pumps are designed for industrial and mobile hydraulic applications, emphasizing versatility, reliability, and ease of installation.

1. Product Series and Features

• B1 & B2 Series: Low noise, low running cost pumps suitable for noise-sensitive industrial and mobile uses. B1 offers 8 versions (5-33 l/min at 1500 rpm, max 18 kW), B2 offers 7 versions (28-62 l/min at 1500 rpm, max 27 kW). Multiple mechanical and hydraulic connection options ensure easy installation and interchangeability.
• BV & BQ Series: Compact, high-power pumps exceeding 225 kW. BV includes 4 single (10-285 l/min) and 6 double pump versions (68-462 l/min). BQ offers 5 single and 7 double pump versions with similar flow ranges. Both use ISO mechanical couplings and SAE hydraulic fittings for standardized installation.
• TQ & TV Series (Thru-drive Pumps): Designed to save space and reduce costs by eliminating double shaft extensions or reducing motor/coupling count. TQ (10 vane) handles sudden pressure peaks; TV (12 vane) focuses on very low noise. These allow coupling with other pump types on a single input drive, enhancing circuit flexibility.
• HQ Series: Available in 2 single (58-132 l/min) and 2 double pump versions (69-200 l/min), max power over 103 kW. Compact design with ISO or UNI mounting for direct PTO coupling and SAE hydraulic fittings. Ports can be oriented for flexible installation and interchangeability.

2. Performance Data and Operating Parameters

Extensive tables provide key parameters for pump selection:

• Displacement (cc/rev)
• Rated flow at 1500 rpm (l/min)
• Maximum operating pressure (bar) for mineral oil, synthetic fluids, and water-glycol mixtures
• Minimum and maximum operating speeds (rpm)
• Pressure ratings vary by fluid type, critical for compatibility and performance

3. Shaft Dimensions and Mounting Options

• Detailed shaft types (Shaft 01, 11, 86, 90) and flange mounting standards (SAE B2 - 101.6 mm, SAE C2 - 127 mm)
• Spline specifications (e.g., SAE B 1613T/DP32, SAE C 1214T/DP24)
• Dimensional data including shaft diameter, length, keyway size, and flange bolt patterns
• Compliance with ISO, SAE, and UNI standards ensures compatibility with various drive systems

4. Installation and Interchangeability

Pumps feature multiple mechanical and hydraulic connection options conforming to ISO, SAE, and UNI standards, facilitating easy installation and interchangeability with other brands (e.g., Vickers, Caterpillar, Denison). Thru-drive models reduce component count and installation space, enabling combined pump drives and flexible hydraulic circuit designs.

5. Maintenance and Service

• Cartridge design encloses all wear components (rotor, vanes, inserts, cam ring, flexible plates, covers) allowing inspection and replacement without disconnecting the pump, minimizing downtime.
• Load balancing via elliptical cam profile reduces radial shaft loads, extending bearing life.
• Thermal and pressure compensation through flexible side plates and counter-pressure chambers maintain optimal clearances and efficiency.
• JBJ Techniques Ltd provides technical support and after-sales service through a dedicated technical office.
