Incorporating two close-coupled Calpeda MXHLM 804 horizontal multistage pumps, this packaged skid delivers flow rates up to 433.4 L\/Min. To overcome static elevation and pipe friction, the wet end can generate up to 42.5 m of head. The dual-pump layout provides both high-pressure reach for upper floors and dependable backup capacity for critical hot and cold water circuits.\u003c\/p\u003e\u003cp\u003eSelf-governing pressure control is governed by calibrated differential pressure switches working alongside an intelligent microprocessor control board. Rather than running both motors continuously, the panel monitors line pressure and engages the assist pump only when fixture demand exceeds single-pump capability. Built-in alternation routines rotate the starting sequence between the two units to promote even component longevity, while delay timers eliminate nuisance short-cycling when small taps are briefly opened.\u003c\/p\u003e\u003cp\u003eBoth suction and discharge pathways are fabricated from high-grade AISI 304 stainless steel manifolds to ensure clean, scale-free fluid conveyance. Water enters through a generously sized 65 mm suction manifold and exits via a 50 mm delivery header configured with an expansion vessel connection point and a clear system pressure gauge. Full-bore isolation ball valves and integrated non-return valves flank each pump, preventing reverse flow and simplifying field servicing.\u003c\/p\u003e\u003cp\u003eIdeal for buildings without three-phase infrastructure, the package operates from a single-phase 230 V electrical connection matching the motor windings. Each 2-pole induction motor spins at roughly 2900 rpm on a 50 Hz supply, producing 1.5 kW (P2) of output power and drawing 9.2 A at rated duty. Constructed to IEC 60034 specifications with Class F thermal insulation, the motors withstand sustained operational loads in demanding plant environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEnhanced Vertical Reach: Uses a 4-stage stainless steel impeller stack in each pump to overcome higher static heads in multi-storey installations.\u003c\/li\u003e\n\u003cli\u003eSmart Duty Alternation: Microprocessor logic and differential pressure switches balance runtime hours across both pumps and prevent rapid motor cycling.\u003c\/li\u003e\n\u003cli\u003eAll-Stainless Manifolds: Welded AISI 304 intake and discharge headers provide superior corrosion resistance and low hydraulic resistance.\u003c\/li\u003e\n\u003cli\u003eWide Temperature Tolerance: Suitable for both chilled water loops and hot water distribution operating between -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003eRobust Motor Sealing: Built with IP54 ingress protection and Class F insulation to ensure reliable operation in humid mechanical rooms.\u003c\/li\u003e\n\u003cli\u003eIndependent Branch Isolation: Fitted with heavy-duty ball valves and check valves so one pump can remain active while the other is serviced.\u003c\/li\u003e\n\u003cli\u003eIntegrated Pressure Monitoring: Includes a manifold-mounted pressure gauge and dedicated port for connecting an external diaphragm tank.\u003c\/li\u003e\n\u003cli\u003eComplete Skid Assembly: Supplied fully assembled and factory tested on a rigid frame with a 24 Months 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 MXHLM 804 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":51423236391159,"sku":"BSM2F 2MXHLM 804","price":15985.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm2f-2mxhlm-804-single-phase-2-x-1-5kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070925","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm2f-2mxhlm-804-single-phase-2-x-1-5kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
