▼Product introduction

The GW/GWP-type pipeline sewage pump is a vertical, single-stage, single-suction centrifugal pump with a compact structure that is directly installed in the pipeline, saving space. Its core advantage lies in its high-efficiency, non-clogging impeller, enabling smooth transport of industrial wastewater and domestic sewage containing solid particles and fibers. The pump operates smoothly, is easy to install and maintain, and is widely applicable to building drainage, municipal sewage discharge, and industrial wastewater treatment, providing a highly efficient pipeline pressurization and sewage discharge solution.

▼Application environment

Urban sewage treatment plants, drainage of basements in residential buildings, sewage systems in commercial buildings, wastewater discharge from factory workshops, and rainwater collection and discharge in municipal engineering projects.

▼Product features and advantages

Robust and durable structure, high pressure resistance, and stable and reliable operation.

High head, adaptable to complex working conditions and long-distance conveying needs.

High efficiency, significant energy saving, and low operating costs.

Good wear resistance of flow-through components, long maintenance cycle, and long service life.

Modular design, highly versatile, and convenient for installation and maintenance.

▼Working principle

The GW/GWP type sewage pipeline pump is a vertical single-stage centrifugal pump. Its core feature is the unique single-channel or double-channel impeller design, which resembles a uniformly shaped curved pipe. This design allows for the smooth passage of long fibers and solid particles, ensuring clog-free sewage discharge. The motor directly drives the impeller to generate centrifugal force for sewage pumping. The pump body's inlet and outlet are on the same horizontal line, allowing for direct installation in the pipeline like a valve.

▼Shopping and maintenance suggestions

Selection: Determine the flow rate, head, and medium characteristics based on operating conditions to match the pump type. Select wear-resistant materials for core flow components and ensure proper power supply. Choose reputable brands for guaranteed service.

Maintenance: Daily monitoring of pressure, temperature rise, and abnormal noise. Regularly inspect shaft seals to ensure lubrication and replace worn parts promptly. Adhere to the principle of "prevention first," and strictly prohibit dry running and operation at the shut-off point.

▼Precautions for use

Pre-start checks: Ensure the pump and pipeline are properly sealed, and that the lubricating oil level in the bearing housing is normal. Avoid idling or dry running.

In-operation monitoring: Carefully observe the pressure, flow rate, and motor current to ensure operation within the rated range and prevent blockages and overloads.

Post-shutdown maintenance: Before stopping the pump, flush the pump chamber and pipeline with clean water to prevent solid particle accumulation. Regularly check the wear of vulnerable parts.
