Drainage Pumps

Submersible and drainage pumps for basements, pits and drainage

How to choose a drainage pump for a basement or sump?

A drainage pump keeps basements, sumps and yards dry — it moves ground and rain water away from the building. The right choice depends on how clean the water is, the volume, and whether the pump is for emergency use or a permanent installation.

Unilift CC is a lightweight composite pump for home and emergency use — it removes water down to a 3 mm level, so the floor is left practically dry. The built-in float switch starts and stops the pump automatically.

Unilift KP is a stainless steel pump for permanent installation in a drainage sump or basement — the durable construction tolerates continuous work through wet seasons.

If the water is dirty or a large flow is needed (drainage, sumps, even sewage), the right choice is Unilift AP, which passes particles up to 50 mm.

Frequently asked questions

What is the difference between Unilift CC and KP?+
CC is a lightweight composite pump mainly for mobile use and emergencies — it drains to a 3 mm level. KP is stainless steel and more durable, made for permanent installation in a sump or basement.
Does a drainage pump work automatically?+
Yes — models with a float switch start and stop automatically with the water level. The pump can be left working in the sump permanently and keeps the room dry even when nobody is around.
Which pump suits dirty water or sewage?+
If the water contains particles or it is sewage, choose Unilift AP, which passes particles up to 50 mm. For a heavier sewage solution (e.g. pumping from a septic tank to the sewer), see our sewage pump selection.
How low does a drainage pump drain?+
Unilift CC removes water down to a 3 mm level — the floor is left practically dry. That makes CC the best choice for drying out after a flood.
