Wastewater Pumps

Taking care of your wastewater

Industrial wastewater isn’t one-size-fits-all, and neither are the pumps that move it. Whether you’re designing a new plant or keeping existing systems running, you need wastewater pumps that handle the job efficiently—without clogging, failing, or slowing production.

We supply a diverse range of industrial wastewater pumps and stirrers designed to tackle everything from light process water to thick sludge and fibrous waste. With options including submersible and surface-mounted pumps, cutters, and stirrers, we’ll help you find the right fit for your plant.

Extensive Range

Tailored pumping solutions

Our Industrial Team are industry-trained and offer in-depth knowledge of industrial pumps and systems. Choose from our extensive range of:

Self-Priming Centrifugal pumps – High-flow solutions for process wastewater transfer.
Diaphragm pumps – For abrasive or chemically aggressive wastewater.
Submersible pumps – For wastewater pits, sumps, and direct tank installations.
Progressive cavity pumps – Easily convey thick sludge and viscous waste.
Stirrers – Keep solids in suspension.
