QDX type stainless steel single-phase submersible pump is a lightweight and corrosion-resistant clean water conveying equipment. It is made of stainless steel precision casting, corrosion-resistant, environmentally friendly, beautiful in appearance, small in size, and durable. The motor adopts F-class insulation and is equipped with thermal protection devices, greatly extending the service life of the pump. We can customize anti-corrosion cables, PTFE machine seals, and parts configuration for high-temperature liquids according to customers' special requirements. Suitable for single-phase 220V power supply, widely used in agriculture, construction, household and industrial fields.
1.Stainless Steel Single-phase Submersible Pump Features
Corrosion resistance and pollution prevention
The pump body, impeller, volute and other flow components are made of 304 or 316L stainless steel, which is resistant to acid, alkali, seawater and general corrosive media (pH 4-10), suitable for high hygiene requirements (such as the pharmaceutical and food industries).
Double end mechanical seal (made of silicon carbide material) combined with fluororubber sealing ring effectively prevents liquid leakage and external impurities from entering, with high sealing reliability.
Security protection design
Equipped with a built-in thermal protector, it automatically cuts off the power supply when the motor overheats, overloads, or loses phase to avoid burning out.
Protection level IP68, insulation level F, capable of long-term operation in environments with a diving depth of ≤ 5m.
Lightweight and easy to use
Compact structure (weight 5-20kg), supports mobile (flexible hose) or fixed (threaded interface) installation, no need for water injection, and can be used immediately when powered on.
Standard 10 meter cable, optional float switch for automatic start stop control.
Efficient and energy-saving
Adopting a centrifugal impeller and volute structure, coupled with a 2860 r/min high-speed motor, the energy conversion efficiency is high, and the operation is smooth and low-noise.
2.Stainless Steel Single-phase Submersible Pump Application scenarios
Application Field | Specific purpose |
Agricultural irrigation | farmland drainage, water well pumping, and garden sprinkler irrigation (medium sand content ≤ 0.1%, particle size ≤ 0.2mm). |
Building drainage | Drainage of accumulated water on construction sites, basement drainage, and temporary water supply for municipal engineering. |
| Family life | Residential water supply, garden irrigation, vehicle washing, fish pond circulation. Industrial assistance |
Industrial assistance | Medical/food industry hygiene transportation, aquaculture oxygenation, and marine aquaculture (requiring 316L material). |
3.Stainless Steel Single-phase Submersible Pump Working principle
QDX pump works based on the principle of centrifugal force:
Start up phase: The pump chamber is pre filled with liquid, and the impeller rotates at high speed under the drive of the motor.
Pumping process:
The liquid is thrown from the center of the impeller to the outer edge by centrifugal force, and is discharged from the outlet after being pressurized by the vortex shell.
A low-pressure zone is formed at the center of the impeller, and the liquid is continuously sucked into the pump chamber under the external atmospheric pressure.
Sealing guarantee:
Double end mechanical seal isolates the motor chamber from the medium, preventing water from infiltrating the motor (oil chamber pressure>external water pressure) and ensuring insulation safety.
4.Service Conditions For Stainless Steel Submersible Pumps
1. The submersible depth of the electric pump shall not exceed 5m.
2. The temperature of the conveying medium shall not exceed 60 ℃.
3. The pH values of the conveying medium are 304 (4-10) and 316 (2-13).
4. The conveying medium contains solid particles with a diameter not exceeding 0.2mm and a volume not exceeding 0.1%.
5.Stainless Steel Submersible Pumps Selection Guide
The selection needs to match the operating parameters and medium characteristics, and the key steps are as follows:
Core parameter calculation
Flow rate (m ³/h): It is necessary to meet the water demand (such as 10-30m ³/h for farmland irrigation and 1.5-5m ³/h for household water supply).
Head (m): actual lifting height+pipeline resistance (it is recommended to choose 1.1-1.2 times the rated head to avoid overload).
Medium characteristics: temperature ≤ 40 ℃, pH value 6.5-8.5 (316L material is required for strong acid/alkali environments).
