Yuantong QDX Small Submersible Pump – A High-Efficiency, Durable, and Reliable Submersible Pumping Solution

I. Product Overview

The Yuantong QDX small submersible pump features a cast steel housing that combines high strength with corrosion resistance, making it suitable for pumping clean water or lightly contaminated water. Comprising a pump unit, a sealing system, and an electric motor, the pump is compact, lightweight, and easy to install. It is widely used in applications such as deep-well water extraction, agricultural irrigation, and industrial circulating water supply.

II. Key Features

1. Durable Cast Steel Construction

Cast steel material: Rust-proof and corrosion-resistant.

Precision casting process: Smooth pump body surface reduces flow resistance and extends service life.

2. High Efficiency, Energy Saving, and Stable Performance

Optimized hydraulic design: Combines a centrifugal impeller with a volute casing; offers a flow rate range of 1.5–10 m³/h and a maximum head of 50m, meeting high-rise water supply needs.

3. Safe and Reliable Sealing Technology

Double-face mechanical seal: Made of wear-resistant fluororubber; ensures zero leakage and safe underwater operation.

Waterproof cable design: Epoxy resin potting process ensures high insulation strength; suitable for submersion depths of up to 5 meters.

4. Quiet Operation and Smart Control

Low-vibration structure: Ensures low noise levels.

Optional float switch: Enables automatic start/stop control for unattended operation.

5. Easy Installation and Maintenance

Integrated design: No pump house required; the unit is submerged directly into the water, saving on installation costs.

Modular structure: Motor and pump can be quickly disassembled; maintenance requires only cleaning the strainer and checking the sealing rings.

III. Typical Application Scenarios

Residential Water Supply: Deep-well extraction and rooftop water tank pressurization.

Agricultural Irrigation: Drip irrigation for fields and sprinkler irrigation for orchards.

Industrial Sector: Cooling water circulation and chemical liquid transfer.

Environmental Engineering: Landscape fountains and wastewater treatment.

IV. Technical Parameters and Selection Guidelines

Media Requirements: Clean water or water with a sand content of ≤0.1% (particle size ≤0.2mm).

Environmental Limits: Water temperature ≤40°C; recommended submersion depth of 0.5–3m.

Selection Reference: Match the power rating to flow rate and head requirements (e.g., QDX1.5-17-0.37 indicates a flow rate of 1.5 m³/h, a head of 17m, and a power of 0.37kW).

Yuantong QDX small submersible pumps offer key advantages such as cast steel construction, high energy efficiency, and multiple safety protection features, making them an ideal choice for domestic, agricultural, and industrial applications. Their modular design and low maintenance costs further enhance their cost-effectiveness, allowing users to select the right model based on their specific needs.
