Function

The West vertical pipeline pump is a high-efficiency, energy-saving fluid transport device. Featuring a vertical structure with aligned inlet and outlet ports of the same diameter, it can be installed directly into the pipeline, saving space and simplifying installation.

Key features include:

High Efficiency and Energy Saving: The direct-coupled design between the impeller and motor minimizes transmission losses. Combined with an optimized hydraulic model, operating efficiency is 15–20% higher than that of traditional centrifugal pumps, making it ideal for long-term, continuous operation.

Low-Noise Operation: High-precision bearings support the pump shaft and motor, effectively balancing radial and axial loads. Operating noise remains below 65 dB, meeting industrial standards for quiet operation.

Corrosion-Resistant Design: Options include stainless steel construction (e.g., 304/316L) and various mechanical seal configurations. It handles fluids ranging from -20°C to 240°C—including clean water, hot water, corrosive liquids, and petroleum products—meeting the needs of sectors such as chemical processing, metallurgy, and HVAC.
Easy Maintenance: The modular structure allows for the replacement of mechanical seals and impellers without dismantling the pipeline. This extends maintenance intervals by 30% and reduces downtime costs.

Widely applied in:

Industrial Sector: Petrochemical feedstock transport, boiler hot water circulation, and wastewater treatment systems.

Municipal Engineering: High-rise building water supply boosting, fire protection systems, and landscape irrigation.

HVAC: Central air conditioning cooling water circulation and district heating systems.

Technical Specifications:

Flow Rate: 0.3–350 m³/h
Head: 12.5–125 m
Power: 0.75–110 kW
Working Pressure: ≤1.6 MPa (high-pressure models available upon request)
