The system includes a Grundfos CM pump, five-way valve, and 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), ensuring corrosion resistance and long service life. The integrated return valve supports system stability, while the modular booster design allows easy installation when paired with a suitable pressure tank.\u003c\/p\u003e\n\n\u003cp\u003eThe pump operates at a rated flow of 3.1 m³\/h with a corresponding head of 27.4 metres. From the performance curve, the unit achieves a maximum head of approximately 36.6 metres at shut-off and delivers a maximum flow of approximately 70 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 0.5 kW electric motor operating on a 1 x 220–240 V, 50 Hz supply. The pressure switch operates within an adjustable pressure range of 1 to 5 bar, allowing flexible 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 System: Operates via pressure switch for demand-based water supply\u003c\/li\u003e\n\u003cli\u003eAdjustable Pressure Control: Operating range of 1–5 bar for flexible system setup\u003c\/li\u003e\n\u003cli\u003eSystem Configuration: Includes CM pump, five-way valve, and pressure switch assembly\u003c\/li\u003e\n\u003cli\u003eTank-Compatible Design: Designed to operate with external pressure tanks for stable performance\u003c\/li\u003e\n\u003cli\u003eLeakage Handling Capability: Suitable for installations with minor continuous leakage conditions\u003c\/li\u003e\n\u003cli\u003eMultistage Hydraulic Design: Ensures smooth and stable pressure delivery\u003c\/li\u003e\n\u003cli\u003eCorrosion-Resistant Construction: Stainless steel wet-end components enhance durability\u003c\/li\u003e\n\u003cli\u003eIntegrated Return Valve: Prevents backflow and maintains system pressure\u003c\/li\u003e\n\u003cli\u003eCompact Booster Layout: Simplifies installation and system integration\u003c\/li\u003e\n\u003cli\u003eLow Maintenance Operation: Simple mechanical control system reduces complexity\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50710856401143,"sku":"98244556","price":1115.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-cmb-3-37-stainless-steel-automatic-pressure-boosting-pump-for-agricultural-use-with-pressure-switch.png?v=1777017531","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-cmb-3-37-stainless-steel-automatic-pressure-boosting-pump-for-agricultural-use-with-pressure-switch","provider":"Foundation Pumps","version":"1.0","type":"link"}
