BEX Series Bidirectional Gear Pump

BEX Gear Pump  Overview

The Bezares BEX series is a heavy-duty, fixed-displacement bushing-style gear pump engineered for high-pressure, high-flow mobile and industrial hydraulic systems. Built with a robust cast iron/steel housing and optimized for bidirectional rotation, the BEX delivers exceptional power-to-weight performance and long service life, making it ideal for demanding truck, excavator, and loader applications where reliability under continuous high pressure is critical.

Features and Benefits

• Rugged Heavy-Duty Construction:

  The BEX series features high-tensile cast iron bodies and covers, delivering superior structural rigidity to minimize deflection and fatigue under extreme pressure cycles. This robust design ensures consistent performance in grueling, continuous-duty environments.
• Advanced Pressure-Balanced Bushing Design:

  Utilizing pressure-balanced bushings instead of roller bearings, the BEX offers increased bearing surface area for superior high-pressure performance. This design provides excellent tolerance to fluid contamination and thermal shock, maintaining high volumetric efficiency while protecting against premature wear.
• Superior High-Pressure and High-Flow Capability:

  Engineered for continuous operating pressures up to 290 bar (4,200 psi) and peak pressures up to 320 bar (4,600 psi), the BEX handles displacements from 85 to 150 cc/rev, supporting flows up to 150 L/min. High-strength alloy steel gears and precision-machined components deliver smooth, reliable power for high-force actuators and complex hydraulic circuits.
• Bidirectional Rotation Capability:

  Optimized for reversible operation, the BEX series supports both clockwise and counter-clockwise rotation, eliminating the need for dedicated left- or right-hand pumps in many applications. This flexibility simplifies system design and inventory management.
• Modular Versatility and Installation Flexibility:

  The BEX series offers versatile mounting options with standard ISO 4 (DIN 5462) and SAE B 2/4-bolt flanges, plus multiple shaft configurations. Its unique dual-port design (side and rear ports) provides unmatched installation flexibility for cramped chassis environments and specialized mobile applications.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
