Product Dewspiption

The Meibao QDX/QX Series all stainless steel small submersible electric pump is a compact, lightweight, and highly efficient pumping solution designed for clean water transfer, domestic water supply, and light industrial circulation. Featuring a precision-cast stainless steel (SUS304) shell, this series offers excellent corrosion resistance, durability, and a sleek, rust-free appearance in a small form factor.

The pump consists of three main parts: water pump, seal, and motor. The motor is located at the upper part with a single-phase or three-phase asynchronous motor structure, while the pump is at the lower part employing an upward suction structure to prevent clogging from sludge.

With F-class insulation, thermal overload protection, and double mechanical seals, the QDX/QX series ensures reliable and safe operation for residential, agricultural, and light industrial applications.



Floating Oil Device
Small size and light weight make the pump easy to install, transport, and handle, ideal for use in confined spaces such as small wells, residential buildings, and tight work areas .

F-Class Motor with Thermal Protection
Equipped with high-temperature motor winding wire, F-class insulation, and built-in thermal overload protector to prevent motor burnout from overcurrent or overheating, significantly extending service life .
Advanced Sealing System
Utilizes double mechanical seals with fluororubber (FKM) for reliable sealing and leak-free performance, effectively protecting the motor from water ingress .

Upward Suction Design
The water pump is located at the lower part of the motor with an upward suction structure, which prevents clogging caused by the pump getting stuck in sludge .

Typical Applications

Domestic Water Supply: Household water boosting, well water pumping, rainwater harvesting, and water tower supply .
Agricultural Irrigation: Farmland irrigation, garden watering, greenhouse irrigation, and crop spraying .
Industrial Drainage: Light industrial water transfer, cooling water circulation, and construction site dewatering .
Aquaculture: Marine aquaculture water circulation and fish pond water transfer .
