Sandy boreholes, large agricultural schemes, and commercial water supply requiring extreme flow rates benefit from this high-capacity constant pressure system. The unit combines a Calpeda 4-inch submersible pump with a LOGICWALL frequency converter, designed for liquids with sand up to 150 g/m³ for continuous duty.
Driven by a 2.2 kW motor at 415V, the hydraulic assembly produces 39 metres of head at 400 L/Min. NORYL® floating impellers move axially against polycarbonate diffusers, preventing stage binding when sand particles are present. The NEMA-standard mechanical interface provides a secure connection point for compatible 4-inch submersible motors.
LOGICWALL provides variable speed control with an integrated user interface for system configuration. Protection includes dry-run detection, overcurrent, overvoltage, undervoltage, and closed outlet monitoring. AISI 304 stainless steel forms the external jacket, and a delivery casing incorporates a non-return valve to help prevent reverse flow during shutdown.
