The system consists of a Grundfos CM pump, a five-way valve, and a pressure switch, enabling automatic operation based on system pressure.\u003c\/p\u003e\n\n\u003cp\u003eThis system requires a pressure tank to be installed to complete the booster setup and maintain stable pressure performance. Once connected to the pipeline and power supply, the unit operates automatically based on pressure demand.\u003c\/p\u003e\n\n\u003cp\u003eThe pump is constructed with a stainless steel pump housing and multistage stainless steel impellers (AISI 304), ensuring corrosion resistance and long service life. The integrated non-return valve supports stable operation and prevents backflow within the system.\u003c\/p\u003e\n\n\u003cp\u003eThe pump operates at a rated flow of 4.7 m³\/h with a corresponding head of 78.2 metres. As shown in the performance data and curve, the unit achieves a maximum head of 93.3 metres at shut-off and delivers a maximum flow of approximately 100 L\/min under low head conditions. The system is not self-priming and supports a maximum suction lift of 1 metre.\u003c\/p\u003e\n\n\u003cp\u003eThe unit is powered by a 1.9 kW electric motor operating on a 1 x 220–240 V, 50 Hz supply. The pressure switch provides adjustable control within a range of 3 to 12 bar, allowing flexible pressure management depending on system requirements.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eAutomatic Operation: Pressure switch enables demand-based start and stop\u003c\/li\u003e\n\u003cli\u003eWide Pressure Control Range: Adjustable between 3–12 bar\u003c\/li\u003e\n\u003cli\u003eSystem Requirement: Requires external pressure tank for proper operation\u003c\/li\u003e\n\u003cli\u003eComplete Assembly: Includes pump, five-way valve, and pressure switch\u003c\/li\u003e\n\u003cli\u003eLeakage-Compatible Design: Suitable for installations with minor continuous leakage\u003c\/li\u003e\n\u003cli\u003eHigh Head Multistage Design for long-distance and elevated water delivery\u003c\/li\u003e\n\u003cli\u003eCorrosion-Resistant Stainless Steel Construction for durability\u003c\/li\u003e\n\u003cli\u003eIntegrated Non-Return Valve to maintain system pressure stability\u003c\/li\u003e\n\u003cli\u003eCompact Layout for simplified installation\u003c\/li\u003e\n\u003cli\u003eLow Maintenance Mechanical Control System\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50710869410039,"sku":"98117634","price":2660.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-cmb-5-93-stainless-steel-automatic-pressure-pump-for-rural-supply-with-pressure-switch.png?v=1777019003","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-cmb-5-93-stainless-steel-automatic-pressure-pump-for-rural-supply-with-pressure-switch","provider":"Foundation Pumps","version":"1.0","type":"link"}
