Product Overview

The GW Series Pipeline Sewage Pump is a pipeline-style sewage pump designed for the transfer of wastewater, sewage and effluent containing solid particles and fibres. The pipeline configuration enables direct inline installation in the discharge pipeline, simplifying the pumping system layout and reducing installation space requirements.

This pump is widely used in municipal wastewater treatment, industrial effluent drainage and urban sewage management. Depending on regional terminology, it may also be referred to as a Pipeline Sewage Pump, Pipeline Wastewater Pump, Pipeline Sewage Pump or GWSewage Pump.

Key Features

• Pipeline configuration enables direct inline installation in the discharge pipeline
• Large flow-passage design provides strong solids-handling capability for sewage and wastewater
• Anti-clogging impeller design reduces the risk of blockage during wastewater transfer
• Reliable, smooth operation with rational structural design
• Straightforward maintenance access with simplified service procedures
• High operating efficiency for reduced energy consumption during continuous sewage pumping

Applications

• Municipal wastewater treatment plant effluent transfer
• Urban sewage collection and drainage systems
• Industrial effluent drainage from manufacturing facilities

• Sewage transfer in water supply and sewerage networks
• Wastewater pumping in industrial and commercial complexes

Customer Benefits

Direct Pipeline Installation

The pipeline configuration enables the pump to be installed directly in the discharge pipeline, eliminating the need for complex piping arrangements and reducing installation space and costs.

Strong Solids-Handling Capability

The large flow-passage design and anti-clogging impeller configuration enable the GW Series to handle sewage and wastewater containing solid particles and fibres without frequent blockages.

Energy-Efficient Operation

The hydraulically optimised impeller design and efficient motor selection reduce power consumption during continuous sewage pumping, lowering utility costs over the pump service life.

Reliable Wastewater Transfer

The robust structural design and rational impeller configuration ensure dependable sewage and wastewater transfer under demanding municipal and industrial operating conditions.

Easy Maintenance Access

The pipeline design and accessible component layout simplify routine inspection and servicing procedures, reducing maintenance time and costs.

Wide Operating Range

With flow rates from 7 to 800 m³/h and heads from 5 to 60 m, the GW Series covers a broad spectrum of municipal and industrial sewage drainage requirements.

Selection Guidance

To select the appropriate GW Series pipeline sewage pump, please provide the following information:

• Required flow rate (m³/h)
• Required head (m)
• Sewage composition (solid particle size, fibre content)
• Pipeline diameter and connection type
• Available voltage and frequency
• Installation space constraints
• Operating conditions and duty cycle

Final model selection should be confirmed according to the actual duty point, sewage composition and project conditions.

Installation and Maintenance

Installation Guidance

The pump should be installed directly in the discharge pipeline with adequate clearance for inspection and maintenance. The suction and discharge pipelines must be properly supported so that no external load is transferred to the pump connections.

Pre-Start Inspection

Before starting the pump, confirm the following:

• Pump is securely mounted and properly aligned in the pipeline
• Pipeline connections are complete and properly sealed
• Inlet and outlet passages are unobstructed
• Motor wiring is correct and terminals are secure
• Rotational direction matches the arrow indicated on the pump casing
• All fasteners are properly tightened

Routine Maintenance

Regular inspection should include:

• Checking mechanical seals for leakage
• Monitoring motor bearing temperature and vibration levels
• Verifying that the pump maintains the required flow and head
• Inspecting impeller and flow passage for blockages
• Inspecting all pipeline connections for signs of wear or leakage

Available Configurations

• Flow rates from 7 to 800 m³/h
• Heads from 5 to 60 m
• Motor powers from 0.75 to 90 kW
• Rotational speeds: 2900 / 1450 r/min
• Outlet diameters from DN50 to DN300
• Various impeller designs for different sewage compositions
