Shijiazhuang Laiye Imort& Export Trading Co., Ltd. is one of the leading manufacturers and suppliers of cbn-5 series single gear pump in China, also supports customized service. If you're going to wholesale high quality cbn-5 series single gear pump made in China, welcome to get pricelist from our factory.

Custom properties

The CBN-5 series is an industrial-grade hydraulic pump designed for medium-to-high pressure systems. It is available in nine displacement options ranging from 20 to 63 ml/r, categorized into three groups to match varied application needs:

Small to medium (20–33 ml/r): ideal for mid-sized agricultural and semi-automatic equipment.

Medium to large (39–55 ml/r): suited for hydraulic presses and light construction machinery.

Large (63 ml/r): designed for heavy-duty hydraulic systems and large industrial equipment.

Built to international standards, each pump features a high-strength cast iron body and is performance-tested for reliability. It offers good maintainability, compatibility, and environmental adaptability, delivering a cost-effective flow solution for machinery, agriculture, and heavy industry.

Product features

Enhanced efficiency and reliability ensure uninterrupted operation. The product utilizes advanced powder metallurgy for integral gear-shaft molding, finished with precision grinding.

Optimized gear design and precise clearance control, along with wear-resistant side plates, deliver high volumetric efficiency, consistency, and improved energy economy.

Its high-strength cast iron body, paired with NBR or FKM seals, provides wide compatibility with hydraulic oil, lubricating oil, and light fuel oil.

Advanced tooth profiling and optimized groove design reduce flow pulsation and noise, enabling smooth, quiet operation.

Key hardened components, validated through rigorous 500-hour full-load testing, extend service life and lower maintenance needs.

Multiple interface options-including metric and imperial ports, plus flange and bracket mounts-support flexible installation.

Customer Collaboration Case Studies

Case Study 1: Heavy Equipment Manufacturer - Stable Power, Enabling Efficient Operation of Mining Equipment
Customer requirements: A well-known mining machinery manufacturer needs to find a main pump for its new medium-sized hydraulic rock drill that can operate stably under continuous high pressure and high-intensity vibration. The pump is required to have a displacement of approximately 52 ml/r and possess extremely high durability and low maintenance costs.
Solution: We recommended the CBN-5 series (52ml/r model). Its high-strength cast iron pump body and precisely machined gear set are specifically designed to handle shock loads.
Cooperation Results: This pump has completed over 2000 hours of rigorous testing on the customer's equipment, demonstrating excellent volumetric efficiency retention and an extremely low failure rate. Customer Feedback: "The stability of the CBN-5 pump exceeded our expectations. It not only ensured equipment uptime, but its standardized interface also saved us a significant amount of time in subsequent maintenance."

Case Study 2: Hydraulic System Integrator - One-Stop Solution for Diverse Project Needs

Customer Requirements: A hydraulic system integrator serving multiple industries frequently needs to procure hydraulic pumps of varying displacements for different projects (from light-duty presses to large metallurgical equipment). They wanted to simplify their supply chain by using a single series of high-quality products covering a full range of displacements to meet the needs of most projects, and required the products to have good compatibility to shorten system commissioning time.
Solution: We presented the complete displacement range of the CBN-5 series, from 20ml/r to 63ml/r, and provided detailed technical support.
Collaboration Results: This integrator has included the CBN-5 series in its standard procurement catalog and successfully applied it in several projects, including hydraulic power units for plastic machinery (39ml/r), small construction vehicles (46ml/r), and auxiliary equipment for steel mills (63ml/r). Customer Feedback: "The full displacement range of the CBN-5 series makes our procurement and inventory management very efficient. The product quality is consistent and stable, and its compatibility with various valves is excellent, significantly shortening our system integration cycle."

Warranty and Packaging

100% tested before leaving the factory: Each pump undergoes full-load performance testing and pressure testing on a standard test bench, with data archived for traceability. We provide a 12-month quality guarantee, as we have high confidence in our manufacturing process.

Professional factory packaging: We use cardboard boxes for small items and export-grade plywood crates for large items. Designed specifically for long-distance transportation and multiple transfers, this ensures that the product arrives at you or your customer in perfect condition.
