pump piston

Design of a new radial piston pump with constant flow

新型径向恒流柱塞泵的设计

The ball piston pump takes ceramic ball of high accuracy as its piston and allocates water by its shaft. With wear-resisting plastic covering on cylinder surface, it establishes seel surface by rigidity of piston and elastoplasticity of plastic, hence greatly reduces flow leakage.
