China Tubular Pump Manufacturer
A Tubular Pump is a high-efficiency axial flow pump designed for large-flow, low-head water transportation. It is widely used in applications such as river water diversion, agricultural irrigation, flood control, municipal drainage, and coastal pumping stations.
Unlike conventional vertical pumps, a tubular pump features a horizontal or inclined tubular structure, where the motor and pump are arranged along the same pipeline axis. This compact design reduces hydraulic losses and improves overall system efficiency.
At Tianjin Kairun Pump Industry Co., Ltd., our tubular pumps are engineered for stable operation, high flow capacity, and long service life, making them suitable for large-scale water conservancy and infrastructure projects.

Bi-directional Axial Flow Pump
China manufacturer Kairun Pump's Bi-directional Axial Flow Pump features a coaxial integration of pump and motor with dual-flow channels, enabling efficient forward and reverse water transfer without the need for additional reversing devices. The straight and symmetrical flow path minimizes hydraulic losses, delivering excellent low-head, high-flow performance. With advantages in energy efficiency, operational stability, and resistance to wear and corrosion, this pump is ideal for water diversion in hydraulic projects, urban flood control, and water system connectivity, providing a flexible and reliable integrated solution for bidirectional water flow management.
Unidirectional Axial Flow Pump
Tianjin Kairun Pump Industry Co., Ltd.'s Unidirectional Axial Flow Pump features an innovative unidirectional flow channel and coaxial integrated pump-motor design, ensuring minimal hydraulic loss, stable operation, and low noise even under continuous high-flow conditions. This pump is suitable for low-head water conveyance, including irrigation, flood control, and water conservancy projects, effectively preventing backflow while maintaining high efficiency. As a trusted Chinese supplier and manufacturer, you can obtain advanced and reliable irrigation solutions directly from our professional factory.
Sluice Gate Axial Flow Pump
The Sluice Gate Axial Flow Pump is an integrated gate pump set manufactured by Kairun, a professional manufacturer in China. It flexibly achieves gravity pumping and power pumping, saving space and reducing construction costs. Reliable sealing performance, corrosion-resistant materials, and factory-controlled production processes make it a highly efficient solution. As a trusted supplier, Kairun Pumps is committed to providing stable water resource regulation for urban drainage, irrigation, and flood control.
Full Flow Axial Flow Pump
Tianjin Kairun Pump Industry Co., Ltd. is a professional manufacturer and supplier in China. Our Full Flow Axial Flow Pumps adopt a compact structure design with wet stator motor and electromechanical integration, featuring a straight flow channel and low hydraulic loss, and are specially designed for low-head, high-flow water delivery applications. The products have advantages such as high efficiency and energy saving, low noise, and strong cavitation resistance, and support horizontal, vertical, and inclined installation methods.
How does this device work?
A tubular pump operates based on the axial flow pumping principle. Water enters the pump through the inlet section and is propelled forward by a rotating impeller installed inside the tubular casing.
The impeller converts mechanical energy from the motor into kinetic energy, allowing water to move smoothly through the pipeline with minimal resistance. This structure enables the pump to deliver very large flow rates while maintaining relatively low energy consumption.
Because the pump body forms part of the pipeline itself, the hydraulic channel remains smooth and streamlined, significantly reducing turbulence and improving efficiency.
What are the characteristics of tubular pumps?
Tubular pumps are widely used in large-scale pumping stations due to their structural and hydraulic advantages.
High Flow Capacity
Designed to transport large volumes of water efficiently, making them ideal for irrigation systems, drainage networks, and water transfer projects.
Compact Pipeline Structure
The pump is integrated directly into the pipeline, reducing installation space and simplifying civil engineering requirements.
High Hydraulic Efficiency
Optimized impeller design and smooth flow channels help reduce energy loss and improve pumping efficiency.
Stable Continuous Operation
Suitable for long-term operation in pumping stations, irrigation systems, and flood control infrastructure.
Flexible Installation Options
Tubular pumps can be installed horizontally or at an inclined angle depending on project requirements.
Applications of Tubular Pumps
Tubular pumps are commonly used in large-scale water management systems where large flow and stable performance are required.
Typical applications include:
Agricultural irrigation and farmland drainage
River water diversion and canal pumping
Municipal flood control and drainage systems
Coastal seawater lifting projects
Water conservancy and pumping stations
Reservoir water transfer systems
These pumps play a crucial role in large-area irrigation and flood management infrastructure.
