Equipped with 2 Calpeda MXH 4802 horizontal multistage pumps, the BS2F 2MXH 4802 package generates up to 2200 L\/Min of full-load flow. To overcome static elevation and pipe friction, the wet end can generate up to 35.3 m of head. This dual-pump arrangement ensures uninterrupted water delivery even when peak facility usage places heavy demand on the main riser.\u003c\/p\u003e\u003cp\u003eSequential pump activation is governed by differential pressure switches with a microprocessor control board mounted directly on the frame. Rather than running both motors unnecessarily during light draw-offs, the controller engages a single unit first and brings the standby pump online only when line pressure continues to fall. Built-in duty changeover logic alternates the lead role between starts, while anti-cycling switch calibration protects contactors from premature wear.\u003c\/p\u003e\u003cp\u003eTwin suction and discharge collectors are precision-fabricated from hygienic stainless steel AISI 304 to withstand demanding thermal and hydraulic loads. Facility plumbers interface with a generous 125 mm suction port and a 100 mm delivery port designed to keep flow velocities stable. Individual isolation ball valves and non-return valves on every branch allow isolated maintenance, complemented by a clear pressure gauge and a dedicated port for an external accumulator vessel.\u003c\/p\u003e\u003cp\u003eConnecting directly to a standard commercial three-phase 415 V power feed, the booster set drives motors specified with a three-phase 400\/690 V winding rating. Every 2-pole induction drive spins at a nominal 2900 rpm (50 Hz), producing 5.5 kW (P2) of mechanical output and drawing 6.2 A per unit. Full compliance with IEC 60034 motor benchmarks and resilient Class F thermal insulation provide long-term electrical stability under sustained plant room duty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-Flow Impeller Design: Incorporates a precision 2-stage stainless steel hydraulic assembly that maximises volumetric output while keeping axial thrust balanced.\u003c\/li\u003e\n\u003cli\u003eAutomated Duty Sharing: Alternates the primary and assist roles automatically through the microprocessor board to ensure even wear across both pumps.\u003c\/li\u003e\n\u003cli\u003eCorrosion-Proof Headers: Uses AISI 304 stainless steel manifolds throughout the fluid path to prevent rust contamination in potable and process water loops.\u003c\/li\u003e\n\u003cli\u003eHot and Cold Fluid Rating: Handles media temperatures spanning from -15 °C to +110 °C, making the skid suitable for chilled circuits and hot-water boosting alike.\u003c\/li\u003e\n\u003cli\u003eIndustrial Ingress Guarding: Rated to IP54 protection levels to shield motor internals and switchgear from airborne particulates and moisture spray.\u003c\/li\u003e\n\u003cli\u003eIndependent Branch Isolation: Pairs heavy-duty ball valves with non-return check valves on each pump leg to prevent backflow and simplify mechanical servicing.\u003c\/li\u003e\n\u003cli\u003eStable Pressure Switching: Relies on calibrated differential pressure switches to maintain consistent cut-in and cut-out bands without rapid motor short-cycling.\u003c\/li\u003e\n\u003cli\u003eTurnkey Skid Reliability: Delivered fully assembled and factory verified on a rigid baseplate with the backing of 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 MXH 4802 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 3000 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423235539191,"sku":"BS2F 2MXH 4802*","price":32059.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxh-4802-three-phase-2-x-5-5kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070901","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxh-4802-three-phase-2-x-5-5kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
