Product details

FSType engineering plastic centrifugal pumpAs a horizontal structure, the pump body is made of engineering plastic ABS and reinforced polypropylene PRR molded in one go, which has the advantages of small volume, light weight, compact structure, and good sealing performance. Mainly used for transporting corrosive liquids such as acids, alkalis, salts, etc. that do not contain suspended solids and particles. The pump body material is non-toxic. It can be widely used in industries such as chemical, pharmaceutical, recycled water, electroplating, environmental protection, electronics, and food.

1. Plastic pumps should be installed horizontally, and the pump body should not bear the weight of the pipeline. For special requirements for vertical installation, the motor must be facing upwards.

2. Add water to the pump body before use. When the suction liquid level is higher than the axis line, open the suction pipeline valve before starting. If the suction liquid level is lower than the pump axis line, the pipeline needs to be equipped with a bottom valve.

3. Before starting the motor, check whether its rotation direction is consistent with the pump direction mark.

4. The conveyed medium and temperature should be within the allowable range of the pump material (see attached table). Centrifugal pumps should be used at temperatures FP ≤ 80 ℃ and FS ≤ 60 ℃. The temperature rise of the motor should not exceed 80 ℃, and the ambient temperature should be less than 40 ℃.

5. No no-load operation is allowed.

Pump malfunction forms and troubleshooting methods

failure mode	cause	Troubleshooting
The pump cannot produce liquid	Pump reversal Leakage in the inlet pipeline There is too little liquid stored in the pump chamber The suction distance is too high Bottom valve leakage Impeller obstructed and unable to rotate	Change the motor wiring Eliminate air leakage Increase the storage capacity Lower the installation position of the pump Clean the bottom valve Clean the pump casing and impeller
Insufficient traffic	The suction pipe diameter is too small Impeller channel blockage Head too high There is air leakage in the suction pipeline Damaged impeller	Replace the liquid inlet Clean the impeller Turn up the outlet valve Eliminate air leakage Replace the impeller
Low head	Too much traffic The speed is too low	Turn down the outlet valve Restore rated speed
Low noise level	There are debris inside the pump Friction between rotating parts and fixed parts Severe wear of the shaft	Check and clean GAP Replace the pump shaft
Leakage of liquid	Loose fixing screws of pump casing Severe wear of mechanical seal	tighten the screws Replace the mechanical seal
