High volume sewage transfer pumps for sewage lifting station
A leading construction company overseas faced a critical challenge: safely and efficiently moving large volumes of sewage and sludge water, with a density of around 1,400 kg / m ³, for a luxury new-build development. The solution was a sewage lift station at the heart of which sat four high-volume pumps, precisely fitted within a dry well and fed from an adjacent tank.
What is a sewage water lifting station?
A sewage water lifting station, also called a lift station or sewage pumping station, is a facility designed to move wastewater uphill when gravity alone isn’ t enough. It collects sewage in an underground wet well and, once the wastewater reaches a certain level, automatically activates pumps to push it through pipes to a higher point in the network— often toward a treatment plant.
When planning a sewage and wastewater system, choosing the right pump and installation type is critical. Pumps can be submerged in a pit, surface-mounted to prime from a tank, or flooded below or beside a tank. Each choice comes with tradeoffs. Surface-mounted pumps must be self-priming— either by design, as with progressing cavity, peristaltic, or AODD pumps, or specified at the design stage for centrifugal models.
While surface-mounted or flooded pumps may cost more upfront, they can reduce long-term maintenance, whereas submerged pumps with motors outside the fluid often require crane removal. Space constraints also play a role: in compact areas like car park chambers, submerged pumps may be the only option.
Maintenance and reliability are always top priorities. Vertical inline and long-coupled pumps allow insitu servicing, keeping motors safely above the fluid, while safeguards such as liquid detectors and small submersible pumps protect the system against flooding.
Our Solution
For this project, we specified four XVIL high-flow vertical inline centrifugal pumps, built for endurance and easy maintenance. Each pump features a spacer coupling, dual bearings to absorb radial forces, and independent shafts— so only the pump shaft needs replacing if necessary.
Each unit handles 180 L / s( 650 m ³/ h), giving a combined capacity of 720 L / s( 2,600 m ³/ h) of sewage. With 10”( 250 mm) ports, AISI-316 stainless steel impellers, and 132 kW motors maintaining 3 – 4 bar pressure, the pumps were paired with three noninvasive electromagnetic flowmeters for 99 % flow accuracy. A 162-kW control panel with five multi-contact float switches automatically manages operation based on sewage levels.
Installed on a concrete plinth, the pumps stay aligned, reduce pipe strain, allow easier maintenance, and keep intakes clear— ensuring reliable, long-term performance.
If you have a project which requires dewatering or simply want a high volume transfer pump in an easy to maintain, low maintenance, reliable unit, speak to North Ridge Pumps to see how we can help.
