Precision HBB gear metering pump are corrosion resistant

The HBB helical gear metering pump is a precision-cast, general-purpose pump with excellent fluid compatibility and superior performance in a wide range of fluid environments. Its defining feature is the friction plate structure on the gear flanks, which achieves metering accuracy of 1‰ under ideal operating conditions. Internal bearings utilize corrosion-resistant sliding bearings, ensuring excellent performance and low noise levels even in environments with relatively poor lubricity.
