Engineered as the BS2F 2MXHL 203 package, this dual-pump skid pairs two Calpeda MXHL 203 horizontal multistage pumps on a unified base frame. Operating in parallel, the twin pumps deliver a combined flow of up to 160 L\/Min across varying daily occupancy levels. Up to 31 m of head can be developed to maintain steady water pressure.\u003c\/p\u003e\u003cp\u003eSequential lead-lag staging and automatic duty alternation are governed by a microprocessor control board working with calibrated differential pressure switches. During light water usage, a single lead pump satisfies system demand, while the second lag pump starts automatically whenever heavier draw-offs cause pressure to dip further. By alternating the lead duty role between both pumps and applying anti-cycling delays, the controller balances mechanical wear evenly and prevents rapid start-stop chatter.\u003c\/p\u003e\u003cp\u003eTwin pump branches join cleanly into common AISI 304 stainless steel suction and delivery manifolds designed for hygienic potable and hot-water service. Main building pipework connects via a 50 mm inlet header and discharges boosted water through a 40 mm outlet header. Individual isolation ball valves and non-return check valves on each pump leg allow one unit to be serviced while the other remains online, complemented by a pressure gauge and an external vessel port.\u003c\/p\u003e\u003cp\u003eThree-phase commercial switchboards energise the control cabinet through a three-phase 415 V mains supply, feeding dual motors wound for three-phase 230\/400 V operation. Each 2-pole induction motor operates at approximately 2900 rpm on 50 Hz power, delivering 0.37 kW (P2) per pump and drawing just 1.4 A under full load. Built with Class F insulation to IEC 60034 standards, both drives offer dependable thermal durability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDual-Pump Duty-Assist Operation: Pairs two horizontal multistage pumps with automatic alternation and cascade staging for balanced wear and operational backup.\u003c\/li\u003e\n\u003cli\u003eThree-Stage Impeller Stack: Utilises a 3-stage stainless steel hydraulic design in each pump to generate smooth, quiet pressure boosting.\u003c\/li\u003e\n\u003cli\u003eMicroprocessor Cascade Logic: Uses differential pressure switches and electronic timers to coordinate sequential pump starts and prevent short-cycling.\u003c\/li\u003e\n\u003cli\u003eHygienic Stainless Manifolds: Fabricated from AISI 304 stainless steel across both headers and pump wet ends to resist corrosion and preserve water quality.\u003c\/li\u003e\n\u003cli\u003eHot and Cold Water Capability: Rated for continuous operation across liquid temperatures from -15 °C to +110 °C in heating or potable systems.\u003c\/li\u003e\n\u003cli\u003eIP54 Enclosure Protection: Shields motors and electrical control gear against dust ingress and water splashes in plantroom installations.\u003c\/li\u003e\n\u003cli\u003eIndependent Branch Isolation: Equips each pump with its own isolation ball valves and non-return valve so maintenance never halts building water supply.\u003c\/li\u003e\n\u003cli\u003eTwo-Year Commercial Warranty: Backed by a 24 Months manufacturer warranty covering the complete factory-tested assembly.\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 203 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 100 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423234654455,"sku":"BS2F 2MXHL 203","price":11795.3,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxhl-203-three-phase-2-x-0-37kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070843","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxhl-203-three-phase-2-x-0-37kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
