Engineered around the Calpeda BSM2F 2MXHLM 203 platform, this compact dual-pump station utilises 2 Calpeda MXHLM 203 horizontal multistage pumps to supply up to 160 L\/Min of flow. When boosting water to upper floors, the system can develop up to 31 m of delivery head. The twin arrangement provides complete peace of mind for hot and cold potable water risers.\u003c\/p\u003e\u003cp\u003eIntelligent staging across both pumps is directed by differential pressure switches with a microprocessor control board that responds smoothly to changing tap usage. When a fixture opens, the primary pump handles routine demand on its own, while the secondary unit steps in automatically during simultaneous peak draw-offs. Alternating the lead pump after each operating cycle prevents stagnation and equalises seal wear, while anti-cycling logic stops rapid starting and stopping.\u003c\/p\u003e\u003cp\u003eAll wetted manifold pipework is constructed from durable stainless steel AISI 304 to preserve water purity and resist internal scaling. The header assembly features a 50 mm suction inlet paired with a 40 mm discharge outlet for straightforward integration into building plumbing. Each pump leg incorporates dedicated isolation ball valves and non-return check valves, alongside an easy-to-read system pressure gauge and a pre-fitted connection point for an external diaphragm tank.\u003c\/p\u003e\u003cp\u003eDesigned for sites without three-phase infrastructure, both the incoming supply and the motor windings operate on single-phase 230 V power. Each 2-pole induction motor runs at approximately 2900 rpm (50 Hz), delivering a compact 0.37 kW (P2) output while drawing just 3 A per unit. Built to IEC 60034 engineering specifications with Class F winding insulation, these drives offer quiet, energy-conscious performance across extended daily duty cycles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMultistage Hydraulic Efficiency: Utilises a 3-stage stainless steel impeller stack to generate smooth, pulse-free pressure boosting for smaller commercial and residential systems.\u003c\/li\u003e\n\u003cli\u003eSmart Lead-Lag Alternation: Rotates duty and standby assignments automatically via the microprocessor controller so both pumps accumulate balanced operating hours.\u003c\/li\u003e\n\u003cli\u003eHygienic Stainless Construction: Features AISI 304 stainless steel suction and delivery manifolds plus pump casings for superior corrosion resistance.\u003c\/li\u003e\n\u003cli\u003eWide Thermal Operating Window: Safely transfers heated or chilled water across a broad liquid temperature spectrum from -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003eProtected Electrical Enclosure: Constructed to IP54 ingress standards to keep moisture splashes and plant room dust away from sensitive electrical components.\u003c\/li\u003e\n\u003cli\u003eBuilt-In Backflow Prevention: Includes spring check valves and full-bore isolation ball valves that stop reverse flow and allow servicing without draining the riser.\u003c\/li\u003e\n\u003cli\u003ePrecision Pressure Sensing: Employs pre-calibrated differential pressure switches that maintain steady line pressure while preventing nuisance motor cycling.\u003c\/li\u003e\n\u003cli\u003ePre-Assembled Assurance: Arrives factory tested on a unified skid frame and supported by a 24 Months warranty for hassle-free commissioning.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2 x Calpeda MXHLM 203 horizontal multistage pumps\u003c\/li\u003e\n\u003cli\u003eStainless steel AISI 304 suction manifold\u003c\/li\u003e\n\u003cli\u003eStainless steel AISI 304 delivery manifold\u003c\/li\u003e\n\u003cli\u003eIsolation ball valves\u003c\/li\u003e\n\u003cli\u003eNon-return valves\u003c\/li\u003e\n\u003cli\u003eMicroprocessor control board with differential pressure switches\u003c\/li\u003e\n\u003cli\u003eSystem pressure gauge\u003c\/li\u003e\n\u003cli\u003eFactory assembled and tested boosting plant\u003c\/li\u003e\n\u003cli\u003eSupports a 100 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423235571959,"sku":"BSM2F 2MXHLM 203","price":11889.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm2f-2mxhlm-203-single-phase-2-x-0-37kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070904","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm2f-2mxhlm-203-single-phase-2-x-0-37kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
