Grundfos UNILIFT KP250-A-1 c/w Float

The Grundfos UNILIFT KP250-A1 is a high-quality stainless steel submersible drainage pump with an integrated float switch for automatic operation based on water level. Designed for pumping grey water and non-aggressive water, this model is ideal for residential, commercial, and light industrial drainage applications where automatic start and stop functionality is required.

Built with corrosion-resistant stainless steel components and a durable motor design, the KP250-A1 provides reliable performance for both portable and permanent installations. The semi-open impeller allows the pump to handle small particles commonly found in drainage water, while continuous motor cooling through the pumped liquid ensures dependable operation during extended use. The float switch protects against dry running and provides convenient automatic control without the need for external systems.
