Evak Residox 400 and 750 Powerful Puddle Sucker Pumps - High Flow Flood Pump
EVAK Residox Ultra-Low-Level Pumps | Pumps Down to 1 mm | No Priming Required | 110V & 230V
The EVAK Residox range, available in the Residox 400 and now the higher-output Residox 750, consists of fully submersible, ultra-low-level puddle pumps designed to remove water down to just 1 mm, yet submersible in up to 5m of water.
These pumps are ideal for flood response, nuisance water removal, basements, plant rooms, internal floors, finished surfaces and construction sites.
Both models are built for demanding conditions. They feature a cast iron pump housing, stainless steel outer case and handle, alloy motor/seal casing, and a highly abrasion-resistant Hytrel vortex impeller. A rubberised NBR suction base protects surfaces and allows the pump to sit directly on finished flooring without causing damage. This makes the Residox equally suitable for internal use and professional site drainage.
The Residox range operates with no priming required, simply place the pump down and switch it on.
Performance Overview
Residox 400
The Residox 400 delivers a flow rate of 250 litres/min with a maximum head of 11 m, providing fast and efficient removal of standing water in both residential and commercial environments.
Residox 750
The newly added Residox 750 offers enhanced performance, with a higher flow of 330 litres/min and an increased head of 16 m. This makes it the preferred choice where water needs to be moved over longer distances, discharged uphill, or cleared more quickly during deeper flooding.
Both models offer a 2 mm free passage, ensuring effective operation even in dirty or debris-laden water typical of flood conditions.
