Built around two horizontal multistage Calpeda MXHL 803 pumps, the BS2F 2MXHL 803 booster set supplies up to 433.4 L\/Min of flow. For vertical risers and pressurised distribution lines, the pump assembly can reach up to 32 m of head. Sharing the hydraulic duty across twin pumps guarantees strong flow delivery during peak hours while preserving standby redundancy.\u003c\/p\u003e\u003cp\u003eControl over pump staging rests with a microprocessor control board guided by calibrated differential pressure switches on the discharge header. Whenever building demand exceeds the capacity of the lead pump, the controller automatically brings the lag unit online to stabilise manifold pressure. Sequential duty alternation rotates the primary pump role on subsequent cycles, while anti-cycling safeguards prevent rapid starting and stopping.\u003c\/p\u003e\u003cp\u003eGenerously sized stainless steel AISI 304 manifolds keep fluid velocities low and minimise head loss across the skid. The assembly features a 65 mm suction header and a 50 mm delivery manifold, complete with a dedicated port for an external expansion vessel and a clear system pressure gauge. Each pump leg includes isolation ball valves and non-return check valves to stop backflow and permit isolated servicing.\u003c\/p\u003e\u003cp\u003eElectrical integration is straightforward using a three-phase 415 V mains supply connected to motors carrying a three-phase 230\/400 V winding rating. Driven by 2-pole induction motors running at 2900 rpm on 50 Hz frequency, each pump produces 1.1 kW (P2) of output power and draws 2.7 A. Engineered to IEC 60034 requirements with Class F insulation, the motor assemblies deliver dependable efficiency during continuous operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-Flow Multistage Hydraulics: Pairs two high-capacity 3-stage pumps to deliver generous water volumes across multi-fixture commercial networks.\u003c\/li\u003e\n\u003cli\u003eMicroprocessor Pressure Regulation: Monitors differential pressure switches to stage the assist pump smoothly as building draw-off increases.\u003c\/li\u003e\n\u003cli\u003eAutomatic Lead-Lag Rotation: Equalises mechanical wear by alternating the starting sequence between both pumps after every duty cycle.\u003c\/li\u003e\n\u003cli\u003eSanitary Stainless Construction: Features AISI 316L stainless steel internal pump components and AISI 304 manifolds for corrosion-free water handling.\u003c\/li\u003e\n\u003cli\u003eHot and Chilled Water Ready: Accommodates liquid temperatures ranging from -15 °C to +110 °C for versatile mechanical services integration.\u003c\/li\u003e\n\u003cli\u003eFull Service Isolation: Includes individual ball valves and non-return valves so either pump can be removed without depressurising the header.\u003c\/li\u003e\n\u003cli\u003eProtected Motor Enclosures: Built with an IP54 ingress rating and Class F insulation to withstand warm, humid plant-room environments.\u003c\/li\u003e\n\u003cli\u003eReady-to-Install Package: Arrives factory assembled and tested with pre-mounted switchgear, manifolds, and a system pressure gauge.\u003c\/li\u003e\n\u003cli\u003eComprehensive Warranty Support: Includes a 24 Months warranty for assured commercial performance.\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 803 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":51423234949367,"sku":"BS2F 2MXHL 803","price":15622.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxhl-803-three-phase-2-x-1-1kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070862","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxhl-803-three-phase-2-x-1-1kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
