Equipped with two horizontal multistage Calpeda MXHL 804 pumps, the BS2F 2MXHL 804 boosting plant delivers up to 433.4 L\/Min of water. The multistage impeller stack can develop up to 42.5 m of head to overcome static building height. Operating as a twin-pump set, it handles heavy peak draw-offs while offering uninterrupted backup protection.\u003c\/p\u003e\u003cp\u003eResponsive staging between the two pumps is handled by differential pressure switches communicating with a dedicated microprocessor control board. During moderate consumption a single unit maintains line pressure, and when demand rises the second pump cuts in automatically to assist. Built-in duty alternation swaps the lead unit on each cycle to balance mechanical wear, while anti-cycling logic prevents rapid start-stop chatter.\u003c\/p\u003e\u003cp\u003eManifold fabrication uses precision-welded stainless steel AISI 304 headers to resist corrosion and maintain low hydraulic resistance. Water enters via a 65 mm suction collector and discharges through a 50 mm outlet manifold fitted with an external tank connection port and a system pressure gauge. Isolation ball valves and non-return check valves on both pump branches allow one pump to be serviced while the other remains active.\u003c\/p\u003e\u003cp\u003eRunning on a standard Australian three-phase 415 V power supply, the package utilises motors wound for three-phase 230\/400 V operation. Each 2-pole induction drive rotates at approximately 2900 rpm on 50 Hz mains power, delivering 1.5 kW (P2) per pump and drawing 3.6 A at full load. Built to IEC 60034 standards, the motors incorporate Class F thermal insulation for dependable continuous duty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFour-Stage Hydraulic Boost: Integrates a 4-stage stainless steel impeller stack in each pump to maintain strong pressure across multi-storey risers.\u003c\/li\u003e\n\u003cli\u003eSmart Cascade Staging: Uses differential pressure switches and microprocessor logic to bring the second pump online only when demand requires it.\u003c\/li\u003e\n\u003cli\u003eAutomated Wear Equalisation: Alternates lead and lag duties after every cycle so both pumps accumulate balanced operating hours.\u003c\/li\u003e\n\u003cli\u003eCorrosion-Proof Wet End: Combines AISI 316L pump internals with AISI 304 manifolds to ensure long service life in potable and hot water lines.\u003c\/li\u003e\n\u003cli\u003eWide Temperature Envelope: Rated for liquid temperatures from -15 °C to +110 °C to support both chilled water and hot water distribution.\u003c\/li\u003e\n\u003cli\u003eLive-Service Valving: Equips each pump leg with isolation ball valves and non-return valves so maintenance never interrupts building supply.\u003c\/li\u003e\n\u003cli\u003eIndustrial Enclosure Sealing: Protected to IP54 against plant-room moisture and dust, paired with Class F motor winding insulation.\u003c\/li\u003e\n\u003cli\u003ePre-Assembled Booster Skid: Delivered factory plumbed, wired, and tested on a unified baseplate with an integrated pressure gauge.\u003c\/li\u003e\n\u003cli\u003eTwo-Year Warranty Backing: Supported by a 24 Months manufacturer warranty for commercial reliability.\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 804 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 500 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423234982135,"sku":"BS2F 2MXHL 804","price":15893.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxhl-804-three-phase-2-x-1-5kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070865","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxhl-804-three-phase-2-x-1-5kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
