Configured with two horizontal multistage Calpeda MXH 1604 pumps, the BS2F 2MXH 1604 boosting plant supplies up to 833.4 L\/Min of flow. Up to 46.5 m of delivery head can be developed to keep upper-level fixtures properly pressurised. This twin-pump skid delivers full-load reinforcement during peak periods while preserving standby security.\u003c\/p\u003e\u003cp\u003eSeamless coordination between both pumps is managed by a microprocessor control board taking pressure feedback from differential pressure switches. When building consumption outstrips a single pump, the controller stages the assist unit online and shuts it down once target pressure returns. Automatic duty alternation rotates the primary starting pump after each cycle, while anti-cycling logic prevents rapid contactor chatter.\u003c\/p\u003e\u003cp\u003eLarge-bore stainless steel AISI 304 manifolds minimise friction losses and resist corrosion across hot or cold water networks. The pipework pairs an 80 mm suction header with a 65 mm discharge manifold, incorporating an external tank connection point and a dial pressure gauge. Heavy-duty isolation ball valves and non-return check valves on each pump leg prevent backflow and allow isolated maintenance.\u003c\/p\u003e\u003cp\u003eBuilt for connection to a three-phase 415 V commercial switchboard, the booster set drives high-output motors rated at three-phase 230\/400 V. Each 2-pole induction motor operates at 2900 rpm on 50 Hz mains power, producing 3 kW (P2) per pump with a rated current draw of 6.6 A. Engineered to IEC 60034 benchmarks with Class F insulation, the drives withstand intensive continuous operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFour-Stage High-Capacity Boost: Combines two 4-stage horizontal pumps to deliver high flow rates against elevated static and friction heads.\u003c\/li\u003e\n\u003cli\u003eSequential Pressure Staging: Uses differential pressure switches and microprocessor logic to match active pump output to real-time building demand.\u003c\/li\u003e\n\u003cli\u003eBalanced Wear Alternation: Rotates the lead and lag pump assignments automatically so both units accumulate equal running hours.\u003c\/li\u003e\n\u003cli\u003eCorrosion-Resistant Stainless Build: Features stainless steel AISI 304 pump wet ends and manifolds for clean, durable operation in potable water systems.\u003c\/li\u003e\n\u003cli\u003eWide Thermal Operating Range: Handles liquid temperatures between -15 °C to +110 °C across heated water loops, chilled lines, and mains boosting.\u003c\/li\u003e\n\u003cli\u003eMaintenance-Ready Valving: Includes individual isolation ball valves and check valves on each branch for servicing without shutting down the header.\u003c\/li\u003e\n\u003cli\u003eProtected Motor Construction: Combines an IP54 ingress rating with Class F winding insulation to resist plant-room dust, splashes, and heat.\u003c\/li\u003e\n\u003cli\u003eFactory-Assembled Package: Arrives pre-plumbed, wired, and tested on a unified baseplate with an onboard system pressure gauge.\u003c\/li\u003e\n\u003cli\u003eDedicated Warranty Protection: Backed by a 24 Months manufacturer warranty for long-term commercial confidence.\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 1604 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 1000 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423235145975,"sku":"BS2F 2MXH 1604*","price":22381.7,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxh-1604-three-phase-2-x-3kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070874","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxh-1604-three-phase-2-x-3kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
