It is supplied as a complete booster unit with an integrated PM2 pressure manager, enabling automatic operation with dry-run protection, restart functionality, and adjustable start pressure.\u003c\/p\u003e\n\n\u003cp\u003eConstructed with a stainless steel pump housing and multistage stainless steel impellers (AISI 304), the pump provides excellent corrosion resistance and long service life. The compact design allows easy installation and reliable performance across a wide range of applications.\u003c\/p\u003e\n\n\u003cp\u003eThe pump operates at a rated flow of 3 m³\/h with a corresponding head of 34.9 metres. Based on the performance curve, the unit delivers a maximum flow of approximately 65 L\/min at low head conditions and achieves a maximum head of approximately 47 metres at shut-off. It supports a self-priming suction lift of up to 4 metres.\u003c\/p\u003e\n\n\u003cp\u003eThe unit is powered by a 0.5 kW electric motor operating on a 1 x 220–230 V, 50 Hz supply. The integrated PM2 pressure manager ensures efficient automatic pressure control without the need for external controllers.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eMotor: 0.5 kW Electric Motor, 1 x 220–230 V, 50 Hz\u003c\/li\u003e\n\u003cli\u003eMaximum Flow: approx. 65 L\/min\u003c\/li\u003e\n\u003cli\u003eMaximum Head: approx. 47 m\u003c\/li\u003e\n\u003cli\u003eRated Flow: 3 m³\/h\u003c\/li\u003e\n\u003cli\u003eRated Head: 34.9 m\u003c\/li\u003e\n\u003cli\u003ePump Type: Self-priming pressure boosting pump\u003c\/li\u003e\n\u003cli\u003eController: Integrated PM2 pressure manager with dry-run protection\u003c\/li\u003e\n\u003cli\u003eConstruction: Stainless steel pump housing with multistage stainless steel impellers (AISI 304)\u003c\/li\u003e\n\u003cli\u003eImpellers: Multistage design (5-stage)\u003c\/li\u003e\n\u003cli\u003eMechanical Seal: AVBE shaft seal\u003c\/li\u003e\n\u003cli\u003eSelf-Priming Capability: Up to 4 m suction lift\u003c\/li\u003e\n\u003cli\u003eReturn Valve: Integrated\u003c\/li\u003e\n\u003cli\u003eMaximum Operating Pressure: 10 bar\u003c\/li\u003e\n\u003cli\u003eMaximum Ambient Temperature: Maximum 50°C\u003c\/li\u003e\n\u003cli\u003ePump Liquid Temperature: Maximum 40°C\u003c\/li\u003e\n\u003cli\u003eInlet Size: 25 mm\u003c\/li\u003e\n\u003cli\u003eOutlet Size: 25 mm\u003c\/li\u003e\n\u003cli\u003eEnclosure Class: IP55\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50710745907447,"sku":"98507629","price":1160.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-cmb-sp-3-47-stainless-steel-self-priming-pressure-boosting-domestic-pump-multistage-impeller.png?v=1777013173","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-cmb-sp-3-47-stainless-steel-self-priming-pressure-boosting-domestic-pump-multistage-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
