Built around two Calpeda MXHL 205 horizontal multistage pumps, the BS2F 2MXHL 205 booster skid combines strong vertical lift with twin-pump security. The package delivers up to 160 L\/Min of combined flow as building occupancy climbs. Where vertical lift is required, the multistage impellers can reach up to 53.5 m of head.\u003c\/p\u003e\u003cp\u003eDual-stage differential pressure switches interface directly with an onboard microprocessor control board to orchestrate lead and assist pump operation. Moderate draw-offs are handled efficiently by the lead pump alone, while heavier simultaneous usage triggers the second pump to hold line pressure steady. Automatic duty alternation rotates the lead role after every cycle and anti-cycling timers suppress rapid switching, ensuring even mechanical wear and long contactor life.\u003c\/p\u003e\u003cp\u003ePolished AISI 304 stainless steel suction and delivery manifolds unite both pump branches into a hygienic, low-loss fluid network. Plumbers connect incoming water mains to the 50 mm suction header and feed building risers from the 40 mm discharge header. Each pump leg incorporates full-bore isolation ball valves and non-return check valves for uninterrupted single-pump servicing, alongside a manifold pressure gauge and a connection port for an external diaphragm vessel.\u003c\/p\u003e\u003cp\u003eRobust three-phase power distribution feeds the control panel via a three-phase 415 V supply, driving motors configured with three-phase 230\/400 V windings. Operating at approximately 2900 rpm on 50 Hz mains frequency, each 2-pole induction motor delivers 0.75 kW (P2) of shaft power and draws 2 A under full hydraulic load. Class F thermal insulation and strict adherence to IEC 60034 standards protect the windings during continuous plantroom operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCascade Twin-Pump Architecture: Combines two horizontal multistage pumps with automatic duty sharing to provide seamless peak-load assistance and standby redundancy.\u003c\/li\u003e\n\u003cli\u003eFive-Stage Impeller Assembly: Features a 5-stage stainless steel hydraulic stack per pump to overcome substantial static height and pipe friction.\u003c\/li\u003e\n\u003cli\u003eMicroprocessor Switch Supervision: Coordinates differential pressure switches with electronic anti-cycling delays to eliminate pressure hunting and starter wear.\u003c\/li\u003e\n\u003cli\u003ePotable-Grade AISI 304 Wet End: Constructed with stainless steel manifolds and pump chambers to safeguard water cleanliness and prevent rust.\u003c\/li\u003e\n\u003cli\u003eBroad Fluid Temperature Rating: Engineered to handle liquid temperatures from -15 °C to +110 °C across hot and cold building water loops.\u003c\/li\u003e\n\u003cli\u003eSealed to IP54 Standards: Protects motor windings and control electronics against dust particles and splashing water in mechanical rooms.\u003c\/li\u003e\n\u003cli\u003eUninterrupted Maintenance Valving: Includes dedicated isolation ball valves and non-return check valves on each pump branch for live servicing.\u003c\/li\u003e\n\u003cli\u003eFactory Warranty Protection: Backed by a 24 Months warranty covering factory assembly and component 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 205 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":51423234752759,"sku":"BS2F 2MXHL 205","price":12613.7,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxhl-205-three-phase-2-x-0-75kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070847","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxhl-205-three-phase-2-x-0-75kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
