QGL Horizontal submersible tubular pump

Horizontal submersible tubular pump
The submersible tubular pump is a horizontal pump type with low head and high flow
rate, featuring a bulb-shaped structure with motor and pump coaxial. It is
primarily used in urban stormwater pump stations, water conservancy flood control,
agricultural irrigation, and drainage projects. Its flow range is 950-46,037 m³/h,
and the head ranges from 1.57 to 7.65 m.
This pump model features a fully integrated all-metal housing design, with the
motor rotor and impeller combined, and is equipped with multiple protective devices
such as overload, leakage, and temperature monitoring. The pump's inlet and outlet
flow channels are optimized via CFD to achieve a hydraulic efficiency of ≥79.5%,
resulting in a 3-5% improvement in overall efficiency compared to traditional pump
types. It adopts a wet stator structure and water-cooling heat dissipation
technology, offering low noise and high-temperature-free characteristics. The pump
supports full lifting and bidirectional pumping functions, reducing civil
excavation depth during pump station construction and saving 20%-30% in investment.
The equipment is compatible with voltage levels from 380V to 10kV and is equipped
with an intelligent monitoring system for unattended operation.
The core structure of the horizontal submerged tubular pump features a coaxial
design where the motor is housed in the "bulb body" behind the impeller, with the
entire unit installed horizontally. Water flows axially through the pump body in a
horizontal direction. This design integrates the motor, reducer, and pump into a
single unit, which operates submerged. The inlet and outlet waterways are nearly
aligned in a straight line, resulting in minimal hydraulic losses, making it
particularly suitable for low-head, high-flow drainage and irrigation scenarios.
Features:
The lifting height is small, the pump house height is low, and the foundation
excavation depth is shallow, effectively reducing geotechnical and construction
engineering investments.
2. The inlet and outlet flow channels are straight, with minimal total hydraulic
losses in the flow path.
3. Since the pump is submerged in water, it operates with low noise and no high
temperatures, improving working conditions and featuring excellent cavitation
performance.
4. Its bulb size is significantly smaller than that of traditional axial flow
pumps, greatly improving the device's efficiency.
5. It can achieve overall reverse installation and bidirectional pumping.
6. It has excellent maintainability.
7. It supports remote and automatic control.
