QDX Type Submersible Pump 1HP 2HP 3HP 5HP 10HP

QDX Type Submersible Pump is an efficient, energy-saving, and corrosion-resistant multifunctional submersible electric pump. It adopts stainless steel centrifugal impeller and double end mechanical seal design, which combines compact and lightweight (weight 10-20kg) with durability. It supports the pumping of clean water, mild sewage, and seawater (sand content ≤ 0.1%). Its flow range is 1.5-100m ³/h, with a maximum head of 60 meters, and it can automatically start and stop (with float switch configuration). It is widely used in scenarios such as household water supply, agricultural irrigation, industrial drainage, and seawater aquaculture. Paired with an IPX8 waterproof motor and 304 stainless steel material, it ensures stable operation in environments ranging from -15 ℃ to 40 ℃, making it an ideal choice that balances performance and reliability.

1.QDX Type Submersible Pump Performance Parameter

2.Feature Of QDX Type Submersible Pump:

• Efficient and energy-saving

  Adopting a centrifugal impeller design, it has high water flow efficiency, low energy consumption, and is suitable for long-term operation.

  Wide power range (0.37~2.2kW), matching models can be selected according to demand.

• Strong corrosion resistance

  Key components such as pump body and impeller are made of 304 stainless steel material, suitable for seawater and mildly corrosive liquids.

  The shaft is treated with hard chrome plating to enhance wear resistance and corrosion resistance.

• Automatic control function

  Some models are equipped with float switches to achieve automatic start stop based on liquid level sensing, without the need for manual supervision.

• Compact and lightweight structure

  Small size, light weight (some models only weigh 10-20kg), easy to move and install.

• Anti clogging design

  The impeller channel is wide and can withstand liquids containing small amounts of particles (≤ 0.2mm), reducing the risk of blockage.

3.Working Principle of QDX Type Submersible Pump

QDX submersible pump works based on the principle of centrifugal pump:

Power transmission: After the motor is powered on, it drives the impeller to rotate at high speed (usually at a speed of ≥ 2800r/min).

Centrifugal force: The impeller blades push the liquid to rotate with the impeller, and the liquid is thrown towards the volute flow channel under the action of centrifugal force.

Pressure increase: The snail shell converts the kinetic energy of the liquid into pressure energy, forming a high-pressure water flow that is discharged through the outlet.

Water absorption process: Negative pressure is formed at the center of the impeller due to the liquid being thrown out, and external liquid is continuously replenished under atmospheric pressure to achieve continuous pumping.

4.Application of QDX Submersible Pump:

• Family and Agriculture: Basement Drainage, Garden Irrigation, Rural Well Water Extraction .

• Industry and Engineering: Construction Drainage, Livestock Circulating Water Treatment, Industrial Water Drainage.

• Special scenarios: aquariums, fountain systems, sewage sampling (requiring matching filters)

5.Product Structure Of QDX Submersible Pump

The QDX submersible pump consists of three core components:

• Electric motor part

  Type: Single phase or three-phase asynchronous motor, waterproof insulation level IPX8.

  Sealing: Double end mechanical seal to prevent water from entering the interior of the motor.

• Water pump section

  Impeller: Stainless steel centrifugal impeller, designed with 4-6 rear curved blades to reduce turbulence.

  Spiral shell: Made of stainless steel, with smooth flow channels and reduced hydraulic losses.

• Connection and sealing system

  Shaft seal: Double end mechanical seal made of hard alloy or silicon carbide material, resistant to high temperature and high pressure.

  Static sealing: "O" - shaped oil resistant rubber rings are used at each interface to ensure overall sealing.

6.Usage conditions and precautions

• Applicable Medium

  Clear water or mild sewage, sand content ≤ 0.1%, particle diameter ≤ 0.2mm.

  Liquid temperature: -15 ℃~+40 ℃ (high temperature models can reach up to 60 ℃).

  PH range: 6.5~8.5 (for corrosive liquids, stainless steel models should be selected).

• INSTALLATION REQUIREMENTS

  Diving depth: It is recommended to be ≤ 5 meters and keep a distance of ≥ 0.5 meters from the bottom of the water to avoid inhaling silt.

  Power supply voltage: single-phase 220V ± 10% or three-phase 380V ± 10%.

• Prohibited use scenarios

  Wastewater containing flammable and explosive liquids, strong acids and alkalis (pH exceeding the range), and impurities such as fibers or long particles.
