Combining two Calpeda MXH 2004 horizontal multistage pumps on a rigid base, the BS2F 2MXH 2004 booster set delivers up to 800 L\/Min of flow. The multistage impeller stack can develop up to 64.5 m of head to overcome static building height. This twin-pump station provides continuous pressure stability and mechanical standby security for demanding hydraulic installations.\u003c\/p\u003e\u003cp\u003ePressure sensing across the discharge line relies on differential pressure switches governed by a dedicated microprocessor control board. Under moderate draw-off, the primary pump maintains system pressure alone, while the secondary pump engages automatically whenever high consumption causes pressure to dip further. Built-in alternation swaps the lead assignment after every cycle to equalise wear, and anti-cycling control logic prevents rapid motor hunting.\u003c\/p\u003e\u003cp\u003eConstructed with heavy-duty stainless steel AISI 304 suction and delivery headers, the manifold assembly ensures hygienic water transport and long-term corrosion resistance. Main pipework connects via an 80 mm suction inlet and a 65 mm discharge outlet, with full-bore isolation ball valves and non-return check valves fitted to each pump branch. An integrated pressure gauge provides instant visual feedback alongside a pre-configured port for an external diaphragm tank.\u003c\/p\u003e\u003cp\u003eStandard Australian three-phase 415 V power feeds two industrial motors wound for three-phase 400\/690 V operation. Each 2-pole induction drive runs at approximately 2900 rpm on a 50 Hz electrical grid, delivering 4 kW (P2) of mechanical power and drawing 5.5 A per pump. Engineered to IEC 60034 standards with Class F thermal insulation, these motors handle continuous commercial workloads with ease.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFour-Stage Hydraulic Power: Uses a precision 4-stage stainless steel impeller stack in each pump to generate high delivery head and steady flow.\u003c\/li\u003e\n\u003cli\u003eIntelligent Lead-Lag Staging: Differential pressure switches and microprocessor logic activate the assist pump only when building demand spikes.\u003c\/li\u003e\n\u003cli\u003eAutomated Wear Balancing: Alternates the duty and standby roles after every run cycle so both pumps accumulate equal operating hours.\u003c\/li\u003e\n\u003cli\u003eCorrosion-Free Stainless Manifolds: AISI 304 suction and delivery headers preserve potable water quality and resist internal pitting.\u003c\/li\u003e\n\u003cli\u003eIndependent Servicing Valves: Equipped with isolation ball valves and check valves to allow single-pump maintenance without interrupting system flow.\u003c\/li\u003e\n\u003cli\u003eBroad Thermal Operating Range: Safely boosts chilled or heated water across liquid temperatures from -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003eProtected Electrical Enclosure: Sealed to IP54 ingress standards to defend motors and switchgear against plant-room dust and water splashes.\u003c\/li\u003e\n\u003cli\u003eComplete Turnkey Reliability: Factory assembled, hydrostatically tested, and backed by a 24 Months manufacturer 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 MXH 2004 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 1000 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423235342583,"sku":"BS2F 2MXH 2004","price":23967.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxh-2004-three-phase-2-x-4kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070888","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxh-2004-three-phase-2-x-4kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
