Lowara DIWA pumps are compact submersible units designed for transferring clean and slightly dirty water in domestic, commercial, and industrial drainage applications. Available in manual and automatic float-switch configurations, these pumps suit basement and cellar drainage, construction site dewatering, and tank emptying duties.
DIWA pumps are manufactured entirely from stainless steel with polyurethane internal coating for excellent abrasion resistance in muddy environments. The double mechanical seal system provides exceptional durability, protecting against seal failure during extended operation.
DIWA pumps simply drop into sumps with a standard power cable and plug connector. The GT variant features a compact fixed float switch for tight installations where standard floats cannot function, offering flexibility for diverse sump pit designs.

Manual models run continuously when powered and require manual switch-off. Automatic float-switch models stop automatically at desired water level, preventing dry-run operation.
DIWA pumps handle up to 8 millimetres suspended solids. This suits typical domestic wastewater and light construction site water.
DIWA pumps are rated for a maximum immersion depth of 7 metres. This covers typical sump pits and basement applications.
DIWA uses AISI 304 stainless which provides good freshwater corrosion resistance. For seawater, AISI 316 stainless offers superior protection.
