The top entry float controller provides accurate water level sensing, ensuring reliable and consistent operation in high demand water systems.\u003c\/p\u003e\n\n\u003cp\u003eThis system integrates the HM90-13 multi-stage stainless steel centrifugal pressure pump, delivering a maximum flow of 90 L\/Min and operating with a maximum pump pressure of 680 kPa. It provides powerful and stable pressure for installations requiring high performance across multiple outlets and extended pipework.\u003c\/p\u003e\n\n\u003cp\u003eThe pump features a high-efficiency multistage centrifugal design with all hydraulic components constructed from stainless steel, including the casing, impellers, and shaft for durability and corrosion resistance. A carbon and ceramic mechanical seal ensures dependable long-term sealing, while the TEFC motor includes IP55 protection, Class F insulation, and built-in thermal overload protection.\u003c\/p\u003e\n\n\u003cp\u003eThe RainBank controller incorporates an integrated dual check valve for backflow protection in compliance with AS\/NZS 3500-1 plumbing requirements. It operates without solenoid valves and includes feedback indicators for system status, ensuring seamless switching between rainwater and mains supply during low tank levels or power interruptions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDual source rainwater harvesting with automatic mains backup\u003c\/li\u003e\n\u003cli\u003eRainwater priority operation with seamless switching\u003c\/li\u003e\n\u003cli\u003eTop entry float controller for accurate water level sensing\u003c\/li\u003e\n\u003cli\u003eHM90-13 multi-stage centrifugal pressure pump\u003c\/li\u003e\n\u003cli\u003eMaximum flow of 90 L\/Min with pump pressure up to 680 kPa\u003c\/li\u003e\n\u003cli\u003eHigh-efficiency multistage stainless steel construction\u003c\/li\u003e\n\u003cli\u003eAll stainless steel hydraulic components\u003c\/li\u003e\n\u003cli\u003e1.40 kW single-phase 240v motor\u003c\/li\u003e\n\u003cli\u003eIP55 motor protection with Class F insulation\u003c\/li\u003e\n\u003cli\u003eBuilt-in thermal overload protection\u003c\/li\u003e\n\u003cli\u003eCarbon and ceramic mechanical seal\u003c\/li\u003e\n\u003cli\u003eIntegrated dual check valve for backflow protection\u003c\/li\u003e\n\u003cli\u003eNo solenoid valves for improved reliability\u003c\/li\u003e\n\u003cli\u003eFeedback indicators for system status and fault alerts\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Davey","offers":[{"title":"Default Title","offer_id":50722209890551,"sku":"KRB4","price":2153.05,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/davey-krb4-stainless-steel-top-entry-rainwater-harvesting-pressure-pump-for-high-demand-water-systems.png?v=1777535699","url":"https:\/\/foundationpumps.com.au\/products\/davey-krb4-stainless-steel-top-entry-rainwater-harvesting-pressure-pump-for-high-demand-water-systems","provider":"Foundation Pumps","version":"1.0","type":"link"}
