Powered by 2 Calpeda MXHLM 405 horizontal multistage pumps, the Calpeda BSM2F 2MXHLM 405 package achieves up to 266.6 L\/Min of full-load flow. For demanding vertical distribution, the multistage design can build up to 52 m of head. It keeps hot and cold water lines stabilised during intense morning and evening demand peaks.\u003c\/p\u003e\u003cp\u003eResponsive cascade operation is governed by differential pressure switches with a microprocessor control board mounted in the integrated cabinet. When a tap opens and manifold pressure reaches the initial cut-in threshold, the lead pump starts smoothly, followed by the lag unit if high consumption persists. Automatic duty alternation rotates the primary assignment after every cycle to ensure uniform wear, while anti-cycling settings prevent rapid motor switching.\u003c\/p\u003e\u003cp\u003eSuction and discharge collectors are precision-crafted from stainless steel AISI 304 to withstand elevated temperatures and resist internal corrosion. Plumbers connect building mains directly to a 50 mm inlet header and a 40 mm outlet header designed for low friction loss. Each pump branch includes dedicated isolation ball valves and non-return check valves, accompanied by a clear system pressure gauge and a tapping point for an external diaphragm vessel.\u003c\/p\u003e\u003cp\u003eBecause both the incoming power feed and motor windings are specified for single-phase 230 V service, the unit installs easily in buildings lacking three-phase supply. Each 2-pole induction motor operates at roughly 2900 rpm (50 Hz), generating 1.1 kW (P2) of shaft power and drawing 7.4 A per pump. Manufactured to IEC 60034 benchmarks with Class F thermal insulation, these drives deliver reliable performance across demanding duty cycles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFive-Stage Impeller Stack: Utilises a 5-stage horizontal multistage hydraulic design to combine strong vertical lift with generous flow capacity.\u003c\/li\u003e\n\u003cli\u003eMicroprocessor Lead-Lag Logic: Stages the standby pump in automatically during peak draw-offs and alternates duty cycles to prevent uneven wear.\u003c\/li\u003e\n\u003cli\u003eStainless Steel Wetted Path: Incorporates AISI 304 stainless steel manifolds and pump bodies to safeguard potable water purity over decades of service.\u003c\/li\u003e\n\u003cli\u003eExtended Thermal Range: Operates reliably with chilled or heated water across liquid temperatures from -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003ePlant Room IP Protection: Sealed to IP54 ingress standards to keep dust particles and splashing water away from electrical connections and windings.\u003c\/li\u003e\n\u003cli\u003eService-Ready Valving: Includes shut-off ball valves and non-return valves on both branches so technicians can isolate either pump without system downtime.\u003c\/li\u003e\n\u003cli\u003eSmooth Pressure Regulation: Uses calibrated differential pressure switches with built-in anti-cycling delays to prevent pressure hunting and relay wear.\u003c\/li\u003e\n\u003cli\u003eAssured Factory Build: Delivered fully assembled and tested on a unified skid baseplate backed by a 24 Months warranty.\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 405 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 200 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423236292855,"sku":"BSM2F 2MXHLM 405","price":14382.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm2f-2mxhlm-405-single-phase-2-x-1-1kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070918","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm2f-2mxhlm-405-single-phase-2-x-1-1kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
