Features of JOFEE pump: PP pump material is PP-H, PP-H has stronger corrosion resistance, wear resistance, better resistance to low temperature and high temperature, and is not easy to crack. The valve ball is further ground and processed by a special machine, with high roundness and good sealing performance. Accurately calculate the moving distance of the diaphragm, reduce the force of the diaphragm, and have a longer service life. The four-bolt connection design has good sealing performance, and the actual dry suction can reach 4-7 meters. Three-section upper and lower cover, flexible and convenient installation. The integrated design of the diaphragm guard has excellent pressure resistance and high temperature resistance, and is widely used in the filter press industry. The diaphragm connecting rod is made of wear-resistant stainless steel, which has better corrosion resistance and longer life. Can provide PP intermediates, aluminum alloy intermediates and stainless steel intermediates.
