Technical performances
The pump barrel is made of machined by using the high quality special-purpose blank. The internal surface adopts the superficial strengthening processing of chrome-planting or the nickel pthosphorus compound plating to achieve the good intensity,the rigidity,wear-resistance and anticorrosion property.

The plunger surface uses the nickel base alloy powder to spurt welding to achieve  good wear-resistance and anticorrosion property.
The valve ball and the valve seat being made of high-carbon chromium stainless steel or ceramics or tungsten carbide material to achieve longer life span.
The pump efficiency is high ,pump inspection cycle is long.
Simple structure with easy installation and usage.
