FPZ corrosion-resistant engineering plastic acid and alkali resistant self-priming plastic pump

Detailed Description

1. Overview of FPZ Plastic Self-priming Pump

The FPZ engineering plastic self-priming pump body is injection molded once with reinforced polypropylene (CFR-PP), featuring high mechanical strength and strong corrosion resistance. The pump cavity is equipped with a liquid suction chamber, liquid storage chamber, liquid return check valve, gas-liquid separation chamber, and return flow hole. Only need to pour priming liquid before the first startup, and no repeated priming is required afterwards. When conveying media, the liquid can be intermittent. If liquid is resumed within 15 minutes after liquid cut-off, the pump can continue suction and delivery. The inner cavity of the pump is smooth, and the impeller is a closed type, adopting two sealing methods: mechanical seal and rubber seal. The mechanical seal does not need additional cooling water. It has the advantages of small volume, light weight, simple structure, easy operation, safety and no leakage. It is mainly used to transport corrosive liquids such as acids, alkalis, salts with a temperature range of -14℃~80℃, but it shall 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, concentrated acids and alkalis, etc.

3. Operation Requirements of FPZ Plastic Self-priming Pump

1. Before installation and use (due to long-distance transportation), carefully check whether all fasteners are loose. If loose, retighten them. Check the concentricity between the pump shaft and the motor shaft, and correct it if there is deviation.

2. The installed pipeline shall not be directly supported on the inlet and outlet flanges of the pump, and additional supporting points must be provided to prevent deformation and damage. The pipeline should be designed with as few pipes as possible to reduce hydraulic loss. No more than two 90° elbows are allowed. The suction pipe shall not leak air, otherwise it will affect the vacuum pumping and liquid discharging time, or result in no liquid discharging and insufficient flow and head.

3. Before starting the pump, open the liquid filling cap, fill the pump body with priming liquid, tighten the liquid filling cap to avoid air leakage. It is strictly forbidden to run the pump without liquid and reverse rotation.

4. For pumps with a bracket bearing box, add cooling engine oil to half of the sight glass before use, otherwise the bearing will be burnt out, and the engine oil should be replaced regularly.

5. The conveyed liquid shall not contain sediment or long soft fibers, so as to prevent clogging and damage to the impeller and mechanical seal.

6. Install a valve at the outlet of the pump. Close the valve first before shutting down, and open the valve first before starting the pump.
