Configured as a twin-pump boosting station with two horizontal multistage Calpeda MXHL 404 units, the BS2F 2MXHL 404 delivers combined flows up to 266.6 L\/Min. To overcome static elevation and pipe friction, the wet end can generate up to 40.5 m of head. Operating as a coordinated pair, the system provides both peak-demand reinforcement and built-in standby security.\u003c\/p\u003e\u003cp\u003eSystem pressure regulation is governed by factory-calibrated differential pressure switches linked directly to a dedicated microprocessor control board. When a single pump cannot satisfy rising fixture demand, the controller seamlessly stages the second pump into service and drops it out once pressure recovers. Built-in duty alternation cycles the lead role between both units, while anti-cycling delay timers protect the starters from frequent short-cycling.\u003c\/p\u003e\u003cp\u003eFluid distribution runs through fabricated stainless steel AISI 304 suction and delivery headers designed to withstand thermal stress and corrosion. A 50 mm inlet manifold feeds the twin pump suctions, which discharge into a common 40 mm outlet header equipped with an external vessel port and a dial pressure gauge. Individual isolation ball valves and spring-loaded check valves on both branches prevent backflow and allow live maintenance.\u003c\/p\u003e\u003cp\u003eBuilt for direct connection to a standard three-phase 415 V switchboard circuit, the booster set drives dual motors wound for three-phase 230\/400 V operation. Each 2-pole induction motor operates at 2900 rpm on a 50 Hz supply, producing 0.75 kW (P2) of mechanical power with a rated current draw of 2 A per unit. Conforming to IEC 60034 specifications, the motors feature Class F insulation for reliable thermal endurance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eElevated Pressure Output: Utilises a precision 4-stage impeller stack in each pump to overcome higher static heads in multi-level pipework.\u003c\/li\u003e\n\u003cli\u003eIntelligent Dual Staging: Employs differential pressure switches and microprocessor logic to bring the assist pump online only when flow demand spikes.\u003c\/li\u003e\n\u003cli\u003eBalanced Wear Rotation: Alternates the lead and lag pump assignments automatically to prevent stagnant seals and uneven motor fatigue.\u003c\/li\u003e\n\u003cli\u003eCorrosion-Resistant Construction: Combines AISI 316L internal pump hydraulics with AISI 304 manifolds for lasting purity in potable water systems.\u003c\/li\u003e\n\u003cli\u003eBroad Temperature Tolerance: Engineered to pump liquids from -15 °C to +110 °C across domestic hot water, HVAC, and process lines.\u003c\/li\u003e\n\u003cli\u003eIndependent Pump Isolation: Includes full-bore ball valves and check valves on each line so one unit can keep running during servicing.\u003c\/li\u003e\n\u003cli\u003eRobust Plant-Room Enclosure: Protected to IP54 standards against moisture and airborne particles alongside Class F motor winding insulation.\u003c\/li\u003e\n\u003cli\u003ePre-Tested Package Design: Delivered fully assembled and factory tested on a unified frame with an integrated system pressure gauge.\u003c\/li\u003e\n\u003cli\u003eDedicated Product Coverage: Backed by a 24 Months warranty covering manufacturing quality and mechanical 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 404 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":51423234851063,"sku":"BS2F 2MXHL 404","price":12909.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxhl-404-three-phase-2-x-0-75kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070855","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxhl-404-three-phase-2-x-0-75kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
