Description

CBHST1-30-ISO Series Gear Pump

The CBHST1-30-ISO series gear pump is a high-performance external meshing hydraulic component, meticulously engineered to meet the rigorous demands of industrial and construction machinery applications. Adhering to international ISO and UNI mounting dimension standards, this pump delivers exceptional durability, efficiency, and compatibility, making it a reliable power source for hydraulic systems.

Construction & Material Advantages

Crafted from high-strength cast iron, the CBHST1-30-ISO gear pump boasts robust load-bearing capacity and resistance to wear, ensuring long-term stable operation even in harsh working environments. Its optimized design features improved rear oil port and oil measurement port configurations, enhancing sealing performance and fluid distribution efficiency. The pump is equipped with self-lubricating sliding bearings, which reduce noise (only 30% of that of ball bearings under the same conditions) and eliminate the need for manual lubrication, significantly lowering maintenance costs. Dual independent mechanical seals form a reliable double barrier against leakage, guaranteeing tightness in both static and dynamic conditions.
