"Little Mouse" QD Dry-Type Submersible Pump — A High-Efficiency, Energy-Saving, and Durable Submersible Pumping Solution

I. Product Overview

The "Little Mouse" QD dry-type submersible pump features a centrifugal impeller and volute casing design, optimized for transporting clean water or media with low impurity content. The motor is positioned at the top of the pump and utilizes a double-face mechanical seal to ensure complete waterproofing, making it suitable for applications such as agricultural irrigation, deep-well water extraction, and construction water supply.

II. Key Features

1. High Efficiency, Energy Saving, and Superior Performance

Wide Flow and Head Range: Flow rates range from 3 to 10 m³/h, with a delivery head of 22 to 80 meters, meeting diverse operational requirements.

Optimized Hydraulic Design: A multi-stage impeller structure enhances pressure stability; operates at 2900 rpm and is compatible with single-phase 220V or three-phase 380V power supplies.

2. Rugged Durability and Reliable Materials

Cast Iron Pump Body: Constructed from durable cast iron.

Guide Vane Technology: Equipped with high-efficiency guide vanes to minimize energy loss in the water flow and extend service life.

3. Safety Protection and Easy Maintenance

Double-Face Mechanical Seal: Rubber sealing rings prevent leakage, ensuring safe operation at depths of up to 5 meters underwater.

Modular Structure: The motor and pump body can be quickly disassembled; maintenance requires only checking the sealing rings and cleaning the filter screen.

4. Quiet Operation and Smart Adaptability

Low-Noise Design: Integrated motor structure ensures quiet operation, making it suitable for nighttime use.

Optional Float Switch: Supports automatic start/stop control for unattended operation.

5. Robust Environmental Adaptability

Media Limitations: Solid impurity content ≤0.1% (particle size ≤0.2mm); media temperature range of -20°C to +40°C.

Anti-Clogging Design: Impeller structure prevents fiber entanglement, enhancing long-term operational stability.

III. Typical Application Scenarios

Agricultural Irrigation: Drip irrigation for fields, orchard spraying, and water supply for aquaculture.

Construction Water Supply: Pressure boosting for high-rise buildings, water tower filling, and construction site drainage. Industrial sector: Cooling water circulation, treatment of lightly contaminated wastewater.

IV. Technical Parameters and Selection Recommendations

Power range: 0.75–2.2 kW; select the model based on flow rate and head requirements (e.g., QD3-33/2-0.75 indicates a flow rate of 3 m³/h and a head of 33 m).

Installation requirements: Submergence depth ≤ 5 m; discharge pipe diameter must match the pump outlet.

The "Little Mouse" (Xiao Lao Shu) QD dry-type submersible pump features high efficiency, energy savings, reliable sealing, and low maintenance costs, making it suitable for various demanding environments. Its modular design and versatility across agricultural, construction, and industrial sectors make it an ideal choice. Users should consider the properties of the pumped medium and specific operating conditions when selecting a model to ensure optimal performance.
