The BS2F 2MXHL 204 booster set meets this requirement by combining two Calpeda MXHL 204 horizontal multistage pumps on a shared skid assembly. The twin-pump station supplies up to 160 L\/Min of combined flow to meet fluctuating daily water demand. For elevated pipework and risers, the multistage hydraulics can develop up to 42.5 m of head.\u003c\/p\u003e\u003cp\u003eIntelligent cascade control manages both pumps through differential pressure switches connected to a central microprocessor control board. When a single fixture opens, the designated lead pump starts to maintain line pressure, and if simultaneous usage causes pressure to fall further, the lag pump engages automatically. Automatic duty alternation swaps the starting sequence between cycles while anti-cycling timers prevent rapid hunting, equalising running hours across both motors.\u003c\/p\u003e\u003cp\u003eCommon AISI 304 stainless steel suction and delivery headers link both pumps into a compact, corrosion-resistant plumbing assembly. Installers connect primary supply lines to a 50 mm suction manifold and route pressurised water out through a 40 mm delivery manifold. Dedicated isolation ball valves and non-return check valves on each branch allow individual pump maintenance without shutting down the building, supported by a system pressure gauge and an external tank connection point.\u003c\/p\u003e\u003cp\u003eIndustrial-grade electrical reliability starts with a three-phase 415 V power supply feeding motors rated for three-phase 230\/400 V winding connections. Each close-coupled 2-pole induction motor runs at approximately 2900 rpm on 50 Hz mains power, producing 0.55 kW (P2) per pump and drawing 1.6 A at rated output. Constructed with Class F insulation in compliance with IEC 60034 standards, the drive units handle continuous commercial duty cycles effortlessly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAutomatic Lead-Lag Alternation: Rotates duty between two identical pumps and stages both units together during peak draw-offs for complete system reliability.\u003c\/li\u003e\n\u003cli\u003eFour-Stage Hydraulic Core: Incorporates a 4-stage stainless steel impeller assembly in each pump to deliver elevated discharge head with high efficiency.\u003c\/li\u003e\n\u003cli\u003eAnti-Cycling Pressure Control: Pairs differential pressure switches with a microprocessor board to prevent nuisance starts and smooth out pressure transitions.\u003c\/li\u003e\n\u003cli\u003eAISI 304 Stainless Construction: Uses corrosion-resistant stainless steel for suction and delivery manifolds as well as all wetted pump components.\u003c\/li\u003e\n\u003cli\u003eWide Thermal Operating Band: Handles liquid temperatures spanning -15 °C to +110 °C for chilled water, potable cold water, and hot water circulation.\u003c\/li\u003e\n\u003cli\u003ePlantroom Weather Sealing: Protected to IP54 ingress standards to keep moisture splashes and airborne dust out of electrical enclosures.\u003c\/li\u003e\n\u003cli\u003eOnline Servicing Capability: Fitted with branch isolation ball valves and non-return valves so one pump can be isolated while the second maintains supply.\u003c\/li\u003e\n\u003cli\u003eComprehensive Warranty Coverage: Supported by a 24 Months manufacturer warranty on the factory-assembled boosting plant.\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 204 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":51423234719991,"sku":"BS2F 2MXHL 204","price":12306.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxhl-204-three-phase-2-x-0-55kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070845","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxhl-204-three-phase-2-x-0-55kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
