Designed for domestic water systems, the Davey KRB2NF RainBank system provides automatic rainwater harvesting by prioritising stored rainwater and switching to mains supply when required. The floatless controller configuration removes the need for an external float, simplifying installation while maintaining reliable operation.
This system integrates the HS50-06 multi-stage stainless steel centrifugal pressure pump, delivering a maximum flow of 80 L/Min and a maximum head of 48 m. It provides consistent pressure across multiple outlets, making it suitable for residential water supply, irrigation, and washing systems.
The pump features a high-efficiency multi-stage design with four-stage glass-filled polycarbonate impellers, supported by a 304 stainless steel casing, shaft, and diffuser components for durability and corrosion resistance. A carbon and ceramic mechanical seal ensures long service life, while the motor includes IP55 protection, Class F insulation, and built-in thermal overload protection.
The RainBank controller incorporates an integrated dual check valve for backflow protection in compliance with AS/NZS 3500-1 plumbing requirements. It enables seamless switching between rainwater and mains supply, ensuring continuous water availability even during low tank levels or power interruptions.
