It is supplied as a complete booster unit with an integrated PM1 pressure manager, allowing automatic start and stop operation based on water demand while protecting the pump from dry running.\u003c\/p\u003e\n\u003cp\u003eThe pump features a robust cast iron pump housing combined with multistage stainless steel impellers (AISI 304), providing strength, corrosion resistance, and consistent performance. The integrated return valve enhances system reliability, while the compact design allows easy installation in residential water systems.\u003c\/p\u003e\n\u003cp\u003eThe pump delivers a rated flow of 1.7 m³\/h with a corresponding head of 23.7 metres. Based on the performance curve, it achieves a maximum head of approximately 36 metres at shut-off and a maximum flow of approximately 40 L\/min under low head conditions. The unit is not self-priming and supports a maximum suction lift of 1 metre.\u003c\/p\u003e\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 PM1 controller operates with a fixed start pressure of 1.5 bar, ensuring consistent pressure boosting performance for household applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eController: Integrated PM1 pressure manager with automatic start\/stop and dry-run protection\u003c\/li\u003e\n\u003cli\u003eMaximum Head: approx. 36 m\u003c\/li\u003e\n\u003cli\u003eMaximum Flow: approx. 40 L\/min\u003c\/li\u003e\n\u003cli\u003eConstruction: Cast iron pump housing with stainless steel impellers (AISI 304)\u003c\/li\u003e\n\u003cli\u003eImpellers: Multistage design (4-stage)\u003c\/li\u003e\n\u003cli\u003eReturn Valve: Integrated for reliable system operation\u003c\/li\u003e\n\u003cli\u003eSuction Capability: Maximum 1 m (non self-priming)\u003c\/li\u003e\n\u003cli\u003eMaximum Operating Pressure: 10 bar\u003c\/li\u003e\n\u003cli\u003eEnclosure Class: IP55\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50710814589175,"sku":"97530097","price":820.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-cmb-1-36-cast-iron-pressure-boosting-pump-for-domestic-use-with-pm1-controller.png?v=1777014984","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-cmb-1-36-cast-iron-pressure-boosting-pump-for-domestic-use-with-pm1-controller","provider":"Foundation Pumps","version":"1.0","type":"link"}
