Characteristics of HZB series
The qualified HZB series gear pumps are general-purpose external gear pumps, circular arc gear pumps, and gear oil pumps. They have good fluid compatibility and excellent performance in conveying non-corrosive fluids. A key feature is the use of friction plates on the gear sides and self-lubricating bearings internally, resulting in good performance in lubricated media.
