Vertical axial flow pump

This Vertical Tubular Well Axial Flow Pump is a high-efficiency, large-flow pump designed for handling clean water or slightly polluted water in water conservancy and water treatment projects. The pump is installed vertically in a well/tubular form, with the motor placed on the upper platform and the pump body submerged in the water, featuring a compact structure, reliable operation, and convenient maintenance. It is suitable for continuous operation in various large-flow, low-head applications.

Feature

1.Stable water intake optimized by tubular well

The integrated steel tubular well improves inflow conditions of the pump unit, eliminates vortex and turbulent flow at pump inlet, avoids cavitation effectively, and ensures continuous stable water intake under fluctuating water levels.

2. Excellent anti – clogging & anti – sediment performance

The tubular well prevents impurities from entering the pump body, reducing blockage risk and extending service life, especially suitable for river water intake and floodcontrol projects.

3. Space – saving installation & lower civil engineering cost

The pump is installed inside the tubular well without large aboveground pump house. It saves construction land, shortens project period and reduces overall investment.

4. Convenient lifting and maintenance

The tubular well acts as a lifting channel. The pump can be directly hoisted out for inspection and repair without draining the entire water pool, improving maintenance efficiency.

5. High – strength steel tubular well for long – term protection

The thickened steel tubular well has strong structural rigidity and impact resistance, protecting the pump unit from external waterflow impact and ensuring stable longtime operation.

Application

1. Water Conservancy & Flood Control

Ideal for flood control, drainage pumping stations, and irrigation systems to manage waterlogging and meet agricultural water demands.

2. Municipal Water Supply & Sewage Treatment

Used in waterworks raw water intake and wastewater treatment plants for reliable large-volume water transfer.

3. Industrial Circulating Water Systems

Suitable for cooling water circulation in power plants, steel mills, and chemical plants, supporting continuous production operations.

4. Water Environment & Diversion Projects

Applied to river/lake water circulation, ecological replenishment, and inter-basin water diversion to optimize water resource allocation.

Installation method

1. Pre-embedded Sleeve Barrel Installation (Mainstream)

Pour concrete pump well, pre-embed the matching steel sleeve barrel during civil construction, fix the barrel with embedded steel bars to ensure verticality and bearing capacity.

Hoist the pump main body into the sleeve barrel, align the positioning flange with the barrel top mounting seat, lock with high-strength bolts.

Connect the outlet pipeline to the side outlet of the sleeve barrel, install gate valve and check valve on the pipeline as required.

Install vertical motor on the pump top, align the transmission shaft coupling, adjust coaxiality, complete electrical wiring and liquid level sensor installation.

2. Post-installation Sleeve Barrel

For completed existing pools without pre-embedding, adopt integral sleeve base fixing, anchor bolt fixing on pool bottom, suitable for reconstruction projects.
