Cbgj2080+1010 pump

The CBGJ2080+1010 is a high-pressure tandem gear pump commonly used in heavy machinery. You must verify the nominal displacement (typically 80ml/r for the front pump and 10ml/r for the rear), the rated pressure (20-25 MPa), and the mounting flange type (e.g., SAE standard). Ensure the spline shaft dimensions and tooth count match your equipment's power take-off (PTO) to avoid installation failure.

Prioritize suppliers using high-strength cast iron bodies rather than aluminum for high-pressure applications. Request volumetric efficiency reports, which should ideally be above 93%. Additionally, confirm the use of high-quality oil seals (such as Viton or NBR) to prevent leakage under extreme temperature fluctuations common in hydraulic systems.

The manufacturer should ideally hold an ISO 9001:2015 certification for quality management. For hydraulic components, check if the products meet JB/T 7041-2006 standards (Chinese hydraulic gear pump standard) or equivalent international benchmarks. Ask for a factory test report for each unit to ensure it has passed pressure and flow stability tests before shipping.

These pumps are primarily engineered for construction machinery, such as wheel loaders (e.g., XCMG, Liugong), cranes, and road rollers. The tandem design allows the CBGJ2080 to power the main hydraulic steering or lifting system, while the 1010 section handles auxiliary functions or pilot control systems simultaneously.

Utilize third-party inspection services to conduct a 'Pre-shipment Inspection' (PSI). Specifically, request a pressure-holding test and a noise level test. For secure transactions, use Made-in-China.com's secured payment services to ensure funds are only released after the bill of lading is verified and the goods meet the agreed-upon specifications.

Hydraulic pumps are heavy and sensitive to internal rust. Ensure the supplier uses anti-rust oil inside the ports and seals them with plastic plugs. The outer packaging must be fumigated wooden crates or heavy-duty reinforced cartons with internal foam molding to prevent movement. For bulk orders, FOB (Free On Board) is recommended to maintain control over freight costs and insurance.

When sourcing on Made-in-China.com, clarify if you need customized shaft lengths or port directions (left-hand vs. right-hand rotation). Negotiate a staggered payment schedule (e.g., 30% deposit, 70% against BL copy). For the CBGJ series, a standard lead time is 15-25 days; avoid suppliers promising 'immediate' shipping for customized tandem configurations as they may be selling refurbished stock.
