The CBS‑D is a high‑efficiency, fixed‑displacement external gear pump engineered for reliable performance in compact hydraulic systems that demand cost‑effective, consistent power output. Built with a robust, lightweight aluminum alloy housing and precision‑ground gear sets, the CBS‑D delivers an excellent power‑to‑weight ratio, making it an ideal choice for direct mounting to truck Power Take‑Offs (PTOs) and other mobile equipment where space is at a premium and dependable operation is non‑negotiable.

CBS-D

Features and Benefits

Rugged High‑Strength Aluminum Alloy Construction:
The CBS‑D is built with high‑tensile, corrosion‑resistant aluminum alloy bodies and covers, providing superior structural rigidity while maintaining a light footprint. This construction minimizes internal deflection under high‑pressure duty cycles, ensuring stable performance and extended service life in harsh working environments.
High‑Performance Precision Gear Design:
Utilizing precision‑machined, hardened steel gears, the CBS‑D offers smooth, low‑noise operation and consistent volumetric efficiency. The tight‑tolerance gear design reduces internal leakage, delivering reliable flow even at elevated pressures and speeds.
Advanced Pressure‑Balanced Shaft Sleeve Technology:
Equipped with pressure‑compensated shaft sleeves, the CBS‑D automatically optimizes internal clearances between gear faces and the housing. This minimizes fluid bypass and friction, ensuring exceptional mechanical efficiency and consistent power delivery across all operating temperatures.
Superior High‑Pressure Capability:
Despite its compact footprint, the CBS‑D is engineered to handle continuous operating pressures of up to 1,450 psi (100 bar) (peak pressure up to 1,800 psi / 125 bar). Its high‑strength components allow it to power a wide range of hydraulic actuators and circuits with smooth, reliable flow.
Modular Versatility and Installation Flexibility:
The CBS‑D series offers a versatile range of displacements (from 4 to 25 cc/rev) and supports common mounting configurations, including standard threaded and SAE port connections. With multiple shaft options (keyed, splined, and flat) and both side and rear porting designs, it provides unmatched installation flexibility for cramped chassis environments and specialized mobile applications.

CBS-D Series Gear Pump FAQ

1. What are CBS-D series gear pumps

The CBS‑D is a reliable, fixed‑displacement gear pump designed as a core component for compact, light‑to‑medium duty hydraulic systems. Featuring a lightweight, high‑strength aluminum alloy construction, it is specifically engineered for applications requiring a good power‑to‑weight ratio and dependable performance, particularly when direct‑mounted to truck Power Take‑Offs (PTOs).

2. What makes the CBS-D series pumps different from standard gear pumps

The CBS‑D is built for consistent performance and value in light‑to‑medium duty environments where cost and weight are key considerations:

Lightweight, Corrosion‑Resistant Housing: The high‑tensile aluminum alloy body offers an excellent balance of strength and low weight, making it ideal for mobile applications where payload is a concern.
Pressure‑Balanced Shaft Sleeve Design: It utilizes advanced, pressure‑compensated shaft sleeves that optimize internal clearances, minimizing leakage and maintaining high volumetric efficiency across varying pressures and temperatures.
Modular Installation Versatility: Available with multiple port configurations (side and rear) and mounting options, the CBS‑D offers greater installation flexibility in cramped chassis environments than basic fixed‑design pumps.

3. What is the working pressure range of CBS-D series pumps

The CBS‑D is a compact performer for medium‑pressure applications. Depending on the specific displacement, the series typically handles:

Continuous Pressure: Up to 1,450 PSI (100 bar).
Intermittent/Peak Pressure: Up to 1,800 PSI (125 bar).

This pressure rating makes the CBS‑D ideal for driving lifting, tail‑lift, and material handling systems on light‑duty utility vehicles and equipment.

4. Can CBS-D series pumps replace other brands

Yes, the CBS‑D is a cost‑effective alternative to many standard aluminum gear pumps. It is often used as a direct replacement or upgrade for pumps in similar displacement ranges, such as:

Parker PGP Series
Vickers VGP Series
Other common SAE‑mounted gear pumps

To ensure a successful swap, verify the Mounting Flange (SAE A or B), Shaft Type (keyed or splined), and Displacement (cc/rev) to match your existing system.

5. What hydraulic oil is suitable for CBS-D series gear pumps

To protect the precision gears and shaft sleeves, the following is recommended:

Oil Type: Premium mineral‑based hydraulic fluids with strong Anti‑Wear (AW) additive packages.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 100 to 150 SUS (20 to 30 cSt), though it can handle cold starts up to 2,000 SUS (430 cSt).
Filtration: Cleanliness is vital for long pump life. A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging the gear faces and sleeves.

6. What is the typical speed range of CBS-D series pumps

The CBS‑D is designed for reliable operation at typical mobile equipment speeds. The standard operating range is 600 to 3,000 RPM, with maximum continuous speeds depending on the specific model and displacement.

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.
