Product Dewspiption

The Meibao OH Series Automatic Coupler is a quick-connect guide rail coupling system specifically designed for submersible sewage pumps. This innovative accessory enables fast, safe, and effortless pump installation and removal without requiring personnel to enter the pump pit or sump.

Constructed from corrosion-resistant materials, the automatic coupler ensures a secure, leak-proof connection between the pump discharge flange and the fixed discharge piping.

The OH Series significantly reduces maintenance time, improves safety, and lowers operational costs for all submersible pump installations in municipal, industrial, and commercial wastewater applications.

Effortless Maintenance
Pumps can be easily lifted and removed along the guide rails using a chain or winch, enabling quick inspection, cleaning, and repair without disturbing the discharge piping.

Secure & Leak-Proof Connection

The coupler provides a tight, reliable seal between the pump discharge and the fixed discharge elbow, preventing leakage and ensuring efficient pump operation.

Corrosion-Resistant Construction

Manufactured from durable, corrosion-resistant materials (SUS304 stainless steel) suitable for long-term submersion in aggressive wastewater environments.

Versatile Compatibility

Designed to accommodate a wide range of submersible pumps with flange discharge connections (DN50 to DN150 or larger), making it suitable for various industrial and municipal applications.

Typical Applications

Municipal Wastewater Treatment: Pumping stations and lift stations.

Industrial Drainage: Factory wastewater and effluent pumping.

Construction Sites: Dewatering applications with submersible pumps.
