Integrating two Calpeda MXH 3201 horizontal multistage pumps on a heavy-duty frame, the BS2F 2MXH 3201 twin booster set delivers a massive combined flow of up to 1466.6 L\/Min. To support elevated outlets and long pipe runs, the package can deliver up to 16.3 m of head. This dual-pump configuration guarantees abundant volume delivery alongside dependable duty-standby security.\u003c\/p\u003e\u003cp\u003eManaging the two high-flow pumps is a microprocessor control board guided by calibrated differential pressure switches on the delivery manifold. During moderate draw-off, the lead pump maintains line pressure single-handedly, while the second unit stages online automatically when heavy demand exceeds single-pump capacity. Built-in duty alternation rotates the primary pump role after each run cycle, and anti-cycling timers prevent rapid start-stop oscillations.\u003c\/p\u003e\u003cp\u003eHigh-flow stainless steel AISI 304 suction and delivery headers accommodate high flow velocities without excessive turbulence or pressure drop. Site pipework interfaces with a generous 100 mm suction inlet and an 80 mm discharge outlet, supported by individual isolation ball valves and non-return check valves on each pump branch. A clear system pressure gauge and a pre-plumbed connection point for an external diaphragm vessel complete the manifold assembly.\u003c\/p\u003e\u003cp\u003eMain switchboard power enters via a three-phase 415 V feed connected to industrial motors featuring three-phase 400\/690 V windings. Each 2-pole induction motor operates at approximately 2900 rpm on a 50 Hz network, producing 4 kW (P2) of mechanical power and drawing 5.5 A per unit. Built to IEC 60034 standards with Class F winding insulation, both motors are engineered for continuous heavy-duty operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-Volume Hydraulic Design: Features a high-flow 2-stage stainless steel impeller assembly in each pump to move large water volumes efficiently.\u003c\/li\u003e\n\u003cli\u003eDemand-Driven Cascade Staging: Differential pressure switches and microprocessor logic engage the second pump only when system consumption peaks.\u003c\/li\u003e\n\u003cli\u003eAutomatic Duty Rotation: Swaps lead and lag pump assignments after every cycle to equalise runtime hours and extend mechanical life.\u003c\/li\u003e\n\u003cli\u003eLarge-Bore Stainless Manifolds: AISI 304 suction and delivery headers prevent corrosion and minimise friction loss at high flow rates.\u003c\/li\u003e\n\u003cli\u003eServiceable Valve Architecture: Individual isolation ball valves and check valves permit maintenance on one pump without halting building supply.\u003c\/li\u003e\n\u003cli\u003eWide Liquid Temperature Range: Capable of pumping cold and hot fluids safely between -15 °C to +110 °C across diverse applications.\u003c\/li\u003e\n\u003cli\u003eRobust Plant-Room Sealing: Enclosures and motors are protected to IP54 standards against airborne dust and splashing water.\u003c\/li\u003e\n\u003cli\u003eComplete Factory Assurance: Arrives pre-assembled, functionally tested, and backed by a 24 Months manufacturer 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 3201 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 2000 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423235408119,"sku":"BS2F 2MXH 3201*","price":23775.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxh-3201-three-phase-2-x-4kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070892","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxh-3201-three-phase-2-x-4kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
