Product Overview

GW Pipeline Sewage Pump is a vertical in-line non-clog centrifugal sewage pump designed for direct pipeline installation in municipal and industrial wastewater systems.

It solves pipeline sewage lifting and transport where space is limited and solid-laden wastewater must pass without blockage.

It is used in urban drainage networks, building basement sewage discharge, industrial wastewater transfer, and retrofit pipeline systems.

How to Select a Pump Model

Determine required flow rate and total dynamic head based on pipeline system resistance
Confirm maximum solid size and fiber content of sewage medium
Verify installation orientation and available shaft space
Check system working pressure compatibility

✔ Model selection should be based on duty point calculation and sewage characteristics to ensure non-clog stability and hydraulic efficiency.

Engineering Notes

Pump must operate within specified hydraulic performance curve range
Continuous operation at low-flow conditions should be avoided
Shaft alignment tolerance must meet installation standards
For high solid concentration media, wear-resistant materials are recommended
Pipeline support must prevent vibration transmission to building structure

Compliance & Quality Assurance

Factory hydraulic performance test before delivery
Impeller dynamic balance verification
Mechanical seal pressure integrity test
Material traceability for main pressure components
Optional third-party inspection upon request

Safety Notice

Do not operate under dry-running condition
Ensure pipeline is fully primed before startup
Disconnect power before maintenance
Do not exceed specified working pressure

OEM & Customization

This pump series supports engineered configuration and duty-based matching. Technical adjustments can be made according to system requirements and installation conditions.

Available options include:

Motor voltage & frequency
Mechanical seal type and configuration
Impeller material selection
Surface coating and corrosion protection

Configuration is determined based on duty point and project specifications.
