The system consists of a Grundfos CM pump, a five-way valve, and a pressure switch, enabling automatic operation 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), providing corrosion resistance and long service life. The integrated non-return valve ensures system stability, while the modular booster configuration allows easy installation when paired with a pressure tank.\u003c\/p\u003e\n\n\u003cp\u003eThe pump operates at a rated flow of 4.7 m³\/h with a corresponding head of 38.6 metres. As shown in the performance curve on page 3, the unit achieves a maximum head of approximately 46.6 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 0.9 kW electric motor operating on a 1 x 220–240 V, 50 Hz supply. The pressure switch operates within an adjustable range of 1 to 5 bar, allowing flexible pressure control based on system requirements. A pressure tank is required for complete system operation.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eAutomatic Booster Operation: Pressure switch enables demand-based start and stop\u003c\/li\u003e\n\u003cli\u003eAdjustable Pressure Range: Configurable between 1–5 bar for system flexibility\u003c\/li\u003e\n\u003cli\u003eComplete Booster Assembly: Includes pump, five-way valve, and pressure switch\u003c\/li\u003e\n\u003cli\u003eTank-Ready Configuration: Designed to operate with external pressure tanks\u003c\/li\u003e\n\u003cli\u003eLeakage Handling Capability: Suitable for systems with minor continuous leakage\u003c\/li\u003e\n\u003cli\u003eMultistage Pump Design: Provides stable and consistent pressure delivery\u003c\/li\u003e\n\u003cli\u003eCorrosion-Resistant Build: Stainless steel construction enhances durability\u003c\/li\u003e\n\u003cli\u003eIntegrated Non-Return Valve: Prevents backflow and maintains line pressure\u003c\/li\u003e\n\u003cli\u003eCompact Installation Layout: Simplifies installation in tight spaces\u003c\/li\u003e\n\u003cli\u003eLow Maintenance System: Mechanical control reduces system complexity\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50710859743479,"sku":"98117630","price":1535.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-cmb-5-47-stainless-steel-automatic-pressure-boosting-pump-for-agricultural-use-with-pressure-switch.png?v=1777017789","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-cmb-5-47-stainless-steel-automatic-pressure-boosting-pump-for-agricultural-use-with-pressure-switch","provider":"Foundation Pumps","version":"1.0","type":"link"}
