Product Introduction
Applicatioms

This black submersible sewage pump features an advanced, large-channel impeller design, offering exceptional non-clogging sewage discharge capabilities and effectively handling large-diameter solid particles as well as long fibrous materials. The pump body is constructed from high-quality cast iron; the motor and pump are integrated coaxially within a submersible structure, ensuring excellent heat dissipation and reliable operation. The motor utilizes Class F insulation and carries an IP68 protection rating; equipped with heavy-duty bearings and mechanical seals, it ensures long-term, stable operation even in harsh environments. With its compact overall structure and ease of installation, it stands as one of the most widely utilized and efficient sewage pumping devices currently employed in municipal, construction, and industrial sectors.

Key Features:

Large-channel, non-clogging impeller design capable of passing large solid particles and long fibers

Fully submersible structure requiring no separate pump room, facilitating easy installation and maintenance

High-quality cast iron pump body and motor casing, offering excellent resistance to corrosion and abrasion

Dual mechanical seals combined with an oil chamber provide reliable sealing and superior leak prevention

Multiple safety protections—including safeguards against motor overheating, phase loss, and water ingress—ensure safe and dependable operation

1. Product Applications

This submersible sewage pump is primarily designed for conveying sewage, wastewater, or rainwater containing solid particles and fibrous materials. Specific applications include:

Sewage Lifting and Discharge: Automatically lifting sewage from basements and sumps up to ground-level drainage networks.

Rainwater/Floodwater Drainage: Rapidly draining accumulated water from locations such as underground garages, tunnels, and culverts.

Industrial Wastewater Treatment: Conveying industrial wastewater containing sediment, fibers, paper scraps, food residues, and similar materials.

Municipal Sewage Treatment: Transporting sludge and lifting screened sewage within municipal wastewater treatment plants.

Construction Site Drainage: Discharging muddy water and sewage from foundation pits and active construction sites.

Livestock Farm Drainage: Conveying and treating manure and wastewater generated at livestock breeding facilities.

Installation Methods:

The pump can be directly submerged for use (portable configuration) or paired with a guide-rail system for automatic coupling installation (fixed configuration), facilitating ease of future maintenance. When equipped with a float switch or liquid level controller, the unit can operate fully automatically without the need for manual supervision.
