Product Overview
For water supply from deep wells, irrigation and mines, the Lowara Z855-05/2A-3 is an 8-inch submersible electric pump that uses a combination of two reduced and three standard impellers to achieve its duty points. This 5-stage configuration delivers 1217 L/Min flow and 123.1 m head.
The 304 stainless steel pump end includes a precision-cast delivery head and motor support, with semi-axial hydraulics using the mixed impeller arrangement. Technopolymer wear rings and an AISI 431 shaft provide mechanical stability, with the unit rated for sand content up to 100 g/m³ and water temperatures up to 25°C.
