Koshin STV-80X Water Pump

Koshin STV-80X water pump for semi-dirty waters is a heavy-duty machine to drain dirty waters, which stands among standard petrol pumps for the large dimensions and exceptional volume of its pump unit.

This pump allows it to handle liquids that may also contain solids, ideal for emptying muddy construction site excavations, muddy bottom ponds and the like. It is also equipped with a special metal filter, resistant to shocks and wear due to debris that semi-dirty waters contain.

The new STV line has unique technical features:
- silicon carbide mechanical seals, much more resistant to abrasion
- impeller and spiral body in spheroidal graphite iron, material which guarantees a much greater resistance, providing the machines with a much longer life even working with muddy waters.

Its high flow rate of a good 900 L per minute, due to its 80 mm fittings and the powerful 4.1 Hp engine, allows draining large quantities of dirty water very quickly.

It is also equipped with a sturdy wraparound frame consisting of a high-strength tubular, which protects it from unwanted shocks.

The pump is self-priming, and you can start it by simply topping up the water through the dedicated cap in the pump body.

Koshin water pump is also equipped with oil level safety device.


  • The engine is provided without oil, remember to fill it before use with the bottles supplied on standard equipment
  • Do not operate the machine with a dry pump

These pumps are suitable for transferring water (e.g. from a tank to another) or for furrow irrigation in fields and gardens.
We do not guarantee the suitability for the combined use with different types of sprinklers or irrigation systems, (as they require the contribution of a qualified technician and a number of calculations in terms of flow rate, head lift, pressure, hose diameter, valves, nozzles, and so on), which may require more specific types of pumps for water systems.
