As a standalone hydraulic wet end, the Lowara ZN622/30 represents a technical solution within the Z6 Series range of submersible borehole pumps. Operating this wet end requires secure coupling with a compatible 30 kW electric motor of the appropriate power rating. Designed for secure installation inside standard 6-inch deep wells, the assembly operates inside standard casings. It is suitable for groundwater supply and irrigation systems, municipal supply lines, and agricultural distribution projects.
To support long-term physical stability during operation, the structural sleeve and discharge head are engineered from cast AISI 316 Stainless Steel. The multi-stage centrifugal hydraulic assembly consists of 30 stages, each incorporating an AISI 316L stainless steel radial impeller. The integrated radial impellers are designed to limit abrasive wear from sand particles, supporting water containing up to 100 g/m³ of suspended sand.
Once paired with its designated 30 kW electric motor (nominal current rating of 61.7 Amps), the coupled assembly achieves up to 401 m maximum head. This multi-stage hydraulic wet end generates a maximum flow of 500 L/Min through its Rp 65 mm threaded connection. All performance parameters are in accordance with manufacturer technical specifications.
The pump has a maximum external diameter of 142 mm for installation inside standard 6-inch borehole wells. Maximum pump immersion depth is 300 m when used with C4S motors and 350 m when used with L6W motors. The lower support bracket incorporates a standard 6" NEMA-compliant mount for simple mechanical motor integration. Safe coupling requires correct mechanical alignment of the pump shaft and the motor shaft during mechanical coupling.
