Featuring two horizontal multistage Calpeda MXHL 405 pumps mounted on a common skid, the BS2F 2MXHL 405 booster set achieves flows up to 266.6 L\/Min. When boosting water to upper floors, the system can develop up to 52 m of delivery head. This dual-pump architecture handles fluctuating daily draw-offs while maintaining a backup unit for critical building services.\u003c\/p\u003e\u003cp\u003eCoordinating the two pumps is an onboard microprocessor control board taking real-time input from differential pressure switches on the delivery side. As water consumption climbs and line pressure dips below the primary threshold, the board sequentially starts the second pump to restore target pressure. Automatic duty alternation balances runtime across both assemblies, and integrated anti-cycling parameters stop nuisance tripping when demand is minimal.\u003c\/p\u003e\u003cp\u003eAll manifold assemblies are crafted from hygienic stainless steel AISI 304 to ensure durability in hot or treated water circuits. Water enters through a shared 50 mm suction manifold and leaves via a 40 mm discharge header fitted with an external tank connection point and an easy-read pressure gauge. Heavy-duty isolation ball valves and non-return check valves on each pump leg prevent reverse rotation and simplify component replacement.\u003c\/p\u003e\u003cp\u003ePowering the booster station requires a three-phase 415 V electrical feed matched to motors with a three-phase 230\/400 V winding rating. Both 2-pole induction motors run at 2900 rpm on 50 Hz mains power, with each unit rated at 1.1 kW (P2) and drawing 2.7 A at full load. Manufactured to IEC 60034 benchmarks with Class F insulation, the drives withstand demanding plant-room duty cycles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-Head Multistage Design: Incorporates a 5-stage hydraulic assembly in both pumps to generate strong vertical lift for taller building risers.\u003c\/li\u003e\n\u003cli\u003eSequential Cascade Control: Uses microprocessor logic and differential pressure switches to match active pump capacity to actual hydraulic demand.\u003c\/li\u003e\n\u003cli\u003eEqualised Pump Runtime: Alternates the starting order after each cycle so both pumps experience identical operational wear over time.\u003c\/li\u003e\n\u003cli\u003eStainless Steel Wet Surfaces: Pair AISI 316L internal pump chambers with welded AISI 304 manifolds for superior resistance to rust and scaling.\u003c\/li\u003e\n\u003cli\u003eHot and Cold Liquid Rating: Operates reliably across a liquid temperature spectrum of -15 °C to +110 °C for diverse thermal applications.\u003c\/li\u003e\n\u003cli\u003eMaintenance-Friendly Valving: Equips every pump branch with dedicated isolation ball valves and non-return valves for uninterrupted servicing.\u003c\/li\u003e\n\u003cli\u003eWeather and Dust Sealing: Features an IP54 protection rating and Class F motor insulation to safeguard electrical components in damp plant rooms.\u003c\/li\u003e\n\u003cli\u003eCommissioning-Ready Skid: Supplied as a factory-assembled, pressure-tested unit complete with an onboard pressure gauge and expansion vessel tee.\u003c\/li\u003e\n\u003cli\u003eManufacturer Warranty Assurance: Covered by a 24 Months warranty supporting commercial and industrial installations.\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 MXHL 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":51423234883831,"sku":"BS2F 2MXHL 405","price":13488.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxhl-405-three-phase-2-x-1-1kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070857","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxhl-405-three-phase-2-x-1-1kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
