Plastic Self-priming Pump

 

Plastic self-priming pump is a horizontal centrifugal pump model with self-priming function, using reinforced polypropylene RPP (for -10℃ ~ 90℃) and imported fluorine resin PVDF (for -10℃ ~ 120℃) injection molding. The shaft seal is corrosion-resistant and mechanically sealed to ensure no leakage. Impeller and shaft body, prevent the key slip and medium intrusion into the metal shaft. There are two kinds of connection forms, direct connection and coupling, direct structure is compact, high efficiency, linkage type adopts two-stage type, convenient installation and disassembly of pump shaft.

 

 

The plastic self-priming pump has high mechanical strength, strong corrosion resistance, and unique scientific structure. The pump chamber is equipped with a suction chamber, a liquid storage chamber, a liquid return check valve, a gas pocket separation chamber, and a return hole. Only need to pour the primer before the boot, do not need to repeat the primer, in the suction medium, the fluid can be intermittent, the liquid can continue to suck within 12 minutes of the liquid, the mechanical seal does not need to add cooling water cooling, fluorine plastic chemical pump is easy to operate, safe and no leakage, is to replace the liquid pump products. It is mainly used for transporting acid, alkali, salt and other corrosive liquids, but it must not be used for transporting some chemicals that have a significant effect on ABS engineering plastics, such as aromatics, halogen derivatives of aliphatic hydrocarbons, ketones and concentrated acids and bases.
