Detailed Description
I. Overview of FPZ Plastic Self-priming Pump
The pump body of FPZ engineering plastic self-priming pump is made of reinforced polypropylene (CFR-PP) through one-time injection molding, which has high mechanical strength and strong corrosion resistance. The pump chamber is equipped with a liquid suction chamber, a liquid storage chamber, a liquid return check valve, a gas-liquid separation chamber, and a return hole. It only needs to be filled with priming liquid before the first startup, and no repeated priming is required afterwards. When sucking and conveying medium, the liquid can be intermittent; if the liquid supply resumes within 15 minutes after the liquid is cut off, the suction and conveying can continue. The inner cavity of the pump body is smooth, the impeller is closed type, and two sealing methods are adopted: mechanical seal and rubber seal. The mechanical seal does not require additional cooling water for cooling, and has the advantages of small size, light weight, simple structure, easy operation, safety and no leakage. It is mainly used to transport corrosive liquids such as acids, alkalis and salts at temperatures ranging from -14°C to 80°C, but it must not be used to transport certain chemicals that have significant effects on ABS engineering plastics, such as aromatic hydrocarbons, halogen derivatives of aliphatic hydrocarbons, ketones and concentrated acids and alkalis.

III. Usage Requirements for FPZ Plastic Self-priming Pump
1. Before installing and using the pump (due to long-distance transportation), carefully check whether all fasteners are loose. If they are loose, retighten them. Check the concentricity between the pump shaft and the motor shaft, and correct it if there is deviation.
2. The installation pipeline shall not be directly supported on the inlet and outlet flanges of the pump. Additional support points must be set to prevent deformation and damage. The pipeline should be modified to have as few pipes as possible to reduce hydraulic loss. The number of 90° elbows shall not exceed two. The suction pipe shall not leak air, otherwise it will affect the vacuuming and liquid discharge time, or cause no liquid discharge and insufficient flow and head.
3. Before starting up, open the liquid injection cover, fill the pump body with priming liquid, and tighten the liquid injection cover to prevent air leakage. It is strictly forbidden to run dry and reverse rotation.
4. For pumps with bracket bearing boxes, cooling oil must be added to half of the sight mirror before use; otherwise, the bearings will be burned out, and the oil must be replaced regularly.
5. The transported liquid must not contain sediment or long soft fibers, so as to prevent clogging and damage to the impeller and mechanical seal.
6. A valve shall be installed at the outlet of the pump. Shut down the pump after closing the valve, and open the valve after starting the pump.
