Product Overview
The Lowara Z855-05/3A-3 is an 8-inch submersible electric pump for water supply from deep wells, irrigation and pressure boosting. This 5-stage configuration uses a combination of three reduced and two standard impellers to deliver 1217 L/Min flow and 117.5 m head.
The 304 stainless steel pump end features a precision-cast delivery head and motor support, with semi-axial hydraulics using the mixed impeller arrangement. Technopolymer POM-C 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.
An 18.5 kW water-filled L6W motor operates on a 415v three-phase supply at 38.5 Amps. NEMA-standard coupling and flange dimensions are incorporated, with the motor rated for immersion depths up to 350 metres. A spring-loaded non-return valve prevents backflow.
