Common Problems And Solutions Of Stainless Steel Submersible Electric Pumps

Feb 09, 2026

The customer reported that the stainless steel submersible pump would automatically trip after a period of time after assembly and immediately run without any response, and could resume operation after waiting for several minutes to ten minutes. Why is this the case? When selecting a stainless steel submersible pump, the model and specifications were not chosen properly: the specific pump head used was very low, and the selected stainless steel submersible pump had a high pump head, which did not meet the working condition standards of the selected sewage pump.

 

The voltage of the switch power supply used on site is unstable:

 

stainless steel submersible pumps, especially those used in rural areas with 220V sewage pumps, cannot reach the standard voltage in many places, resulting in a significant increase in current in the rotor winding of the pump motor, which may cause the ambient temperature of the rotor winding to rise significantly and burn out the motor.

 

 

Common reflective faults of stainless steel submersible pumps: Severe damage to the rolling bearings of stainless steel submersible pumps, friction between the motor stator and rotor causing cylinder jamming, or blockage of the centrifugal impeller by dirt inside the pump casing can all lead to continuous load tripping of stainless steel submersible pumps.

 

Stainless steel submersible pumps have problems since leaving the factory:

 

the load on stainless steel submersible pumps is caused by quality issues during production and maintenance. Therefore, when the stainless steel submersible pump experiences a power outage, strictly follow the basic methods to check the power supply current, rolling bearings, etc., to ensure that the equipment runs smoothly.

 

Standards and regulations for the use of stainless steel submersible electric pumps

 

Stainless steel submersible electric pumps not only have good physical properties and production characteristics, but also need to meet other performance requirements, such as easy degassing, low saturation vapor pressure, certain chemical resistance, and have certain standards for the operating environment. Stainless steel submersible electric pump refers to a vacuum pump process with no special requirements. This product has basic environmental requirements: no accumulated pollutants, no floating dust on the surface, no iron pins, and no rust are required in any place where machinery and equipment are stored.

The surface of the vacuum system of this product should be smooth, free of soft tissue and air vents, and there should be no internal welding or other factors that may affect the vacuum pump. The moving components inside the vacuum pump room cannot be lubricated with car oil. Instead, saturated vapor low pressure diffusion pump oil and methyl silicone oil can be used as lubricants; The sealing components of flanges and windows need to be coated with high vacuum vegetable oil.

 

 

Stainless steel submersible electric pumps generally need to work in a clean and ventilated indoor environment with an ambient temperature of 15-30 ℃ and an air humidity not exceeding 70%. The temperature of the water cooling and seepage environment should not exceed 25 ℃. Only in the right living environment can stainless steel submersible pumps achieve good results, so we must strictly follow the above environmental conditions for actual operation.
