Engineering plastic self-priming pump self-priming pump

Engineering plastic self-priming pumpAdopting reinforced polypropylene (CFR-PP) for one-time injection molding, it has high mechanical strength and strong corrosion resistance. The self-priming pump structure has a scientific design, with a suction chamber, storage chamber, return check valve, gas-liquid separation chamber, and return hole inside the pump chamber. Just need to inject the liquid before * startup, there is no need to repeat the injection in the future. When sucking and delivering the medium, the liquid can be intermittent. Within 15 minutes of interruption, the liquid can continue to be sucked and delivered. The mechanical seal does not require additional cooling water, making it easy to operate, safe, and leak free. It is a product that replaces submersible pumps. CFR-PP material: non-toxic, non polluting, resistant to general acids, bases, and salts, with a working temperature range of -14 ℃ to 80 ℃.

Model meaning：

Engineering plastic self-priming pumpIt has the advantages of small size, light weight, simple structure, convenient use, high efficiency, and low price. The inner cavity of the pump body is smooth, the impeller is closed, and two types of mechanical seals and rubber ring seals are used. The entire shaft is made of stainless steel and connected with a sleeve. The temperature of the conveying medium is -20 ℃~80 ℃, the flow rate is 4-25m3/h, the head is 7-25m, the speed is 2900r/min

Attention to selection of self-priming pump

1. Strict procedures must be followed when purchasing water pumps.

When choosing a water pump, it is also necessary to verify it. Only with complete three certificates can we avoid purchasing obsolete and inferior products.
2. Choose self-priming pumps according to local conditions

3. Choose a water pump that exceeds the standard appropriately.

After determining the type of water pump, its economic performance should be considered, especially the selection of the pump's head, flow rate, and supporting power. It must be noted that the head indicated on the water pump label (total head) is different from the actual head at the time of use (actual head), as there will be some resistance loss when the water flows through the water supply pipe and near the pipeline. So, the actual head is generally 10% to 20% lower than the total head, and the water output is correspondingly reduced.
