Zenit DR Steel 37 240v Compact Stainless Steel Drainage Pumps with Float Switch (Max 150LPM/140kPa)

The Zenit DR Steel 37 is a compact, high-performance submersible drainage pump designed for the reliable removal of clean and slightly soiled water. Constructed from durable chrome-nickel AISI 304 stainless steel, this pump is ideal for stormwater dewatering, draining flooded rooms, emptying tanks, or transferring water from ponds, pits, and rainwater collection systems.

Powered by a robust 0.37 kW motor with built-in thermal overload protection, the DR Steel 37 delivers a maximum head of 13.6 metres and a maximum flow rate of 150 litres per minute, making it suitable for both residential and light commercial applications. The 10 mm free passage impeller allows it to handle small suspended solids with ease.

Equipped with an integrated float switch for automatic operation and a 10-metre power cable, this IP68-rated pump is built for continuous duty (S1) operation and safe long-term submersion up to 10 metres.
