Product Overview
The FPZ Corrosion Resistant Plastic Self-priming Pump is injection molded from reinforced polypropylene (CFP-PP). The machine has high mechanical strength and strong corrosion resistance. The self-priming pump has a unique scientific structure. The pump chamber is provided with a liquid suction chamber, a liquid storage chamber, a liquid return check valve, a gas-liquid separation chamber and a return hole. It is only necessary to infuse the liquid before the first start, and it is not necessary to repeat the perfusion. After the medium is sucked, the liquid can be intermittently stopped. The liquid can be continuously sucked within 15 minutes after the liquid is turned off, and the mechanical seal does not need to be added. Cooling water cooling, easy to operate, safe and leak-free, is the best product to replace the submerged pump.
 
Features
The impeller and shaft are integrated to prevent the key from slipping and the medium invading the metal shaft. The direct structure is compact and the efficiency is high; the linkage type adopts two-stage type, and the pump shaft is convenient to assemble and disassemble. Applicable -10°C～90°C, flow rate 11-50 m3/h, head 18-32m, speed 2900r/min
 
Product use
Applicable to general acid resistance Alkali salts, chemical, pharmaceutical, food, smelting, environmental protection, sewage treatment, inorganic salt and other industries.
