Stainless Steel Submersible Drainage Pumps
A stainless submersible drainage pump is a corrosion-resistant portable or fixed submersible pump that moves clean and lightly dirty water with its stainless steel body.
It is used for basement flooding, pool emptying, construction drainage and applications with aggressive water. The product range includes 0.5–5 HP models in 220 V and 380 V.
Main Applications
- Basement flood removal
- Pool and tank emptying
- Construction and excavation drainage
- Lightly dirty water removal
- Aggressive and salt water (depending on model)
- Lift pit drainage
