Koshin’s submersible pump range covers the Ponstar family, electric pumps designed to sit down in the water they’re pumping rather than drawing from above. They’re built for drainage and dewatering, from construction sites through to flood response and general site clearance.
The range spans heavy-duty models built to cope with dry running and sandy or muddy water, through to lighter pumps designed to clear water down to just a few millimetres in narrow spaces like manholes and pits. Whatever the depth or debris content of the water, there’s a Ponstar model built for it.
Unlike the engine-driven Honda range, these pumps run on mains electricity, which suits fixed or semi-permanent drainage setups rather than fully portable off-grid work. Get in touch with our team if you’d like help matching a model to your application.
