Built with 3 x Calpeda MXH-F 4803 multistage pump assemblies, the package delivers a maximum volumetric flow rate of 3000 L\/min to overcome sudden demand spikes across commercial pipework. The hydraulic wet ends produce a maximum shut-off head of 60.5 metres to maintain constant vertical static elevation without line starvation.\u003c\/p\u003e\u003cp\u003eThrough precision multi-motor velocity regulation, the 3-pump set easily achieves total flows up to 3000 L\/min. System regulation is controlled by an integrated I-MAT variable speed control system governing all three pumps in automated coordination. The pumps dynamically adjust their operating frequency to match instantaneous draw-off rates, eliminating mechanical water hammer and destructive line pressure surges. A factory-plumbed 18 L membrane pressure vessel dampens transient micro-fluctuations, while digital pressure transducers provide real-time line feedback to protect against dry running.\u003c\/p\u003e\u003cp\u003eThe self-contained 3-pump skid package is supported by an ultra-tough structural base frame. Hydraulic construction utilizes premium 304 Stainless Steel impellers, stage chambers, and pump casings for superior corrosion resistance and longevity. The 3-stage hydraulic stacks connect into common manifolds featuring a 125 mm suction port and a 125 mm delivery connection. Each individual pump line incorporates dedicated nickel-plated brass shut-off ball valves and non-return check valves mounted on a vibration-dampened S235JR steel baseplate.\u003c\/p\u003e\u003cp\u003eThe triplex electrical power assembly utilizes industrial-grade motors engineered for multi-inverter duty. Operating with a full-load current rating of 3 x 8.3 Amps, the TEFC motor configuration incorporates IP54 ingress protection and Class F thermal winding insulation. The package is rated for continuous fluid temperatures from -15°C to +110°C and ambient plant room environments up to 40°C. Manufactured to strict European standards, the entire variable-speed booster system is backed by a comprehensive 24 Months manufacturer warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAdvanced I-MAT variable speed drives provide smooth soft-start and soft-stop acceleration to safeguard downstream mechanical pipework.\u003c\/li\u003e\n\u003cli\u003eOperating under three-pump cascade control, the parallel array satisfies extreme simultaneous fixture demand up to 3000 L\/min.\u003c\/li\u003e\n\u003cli\u003eHigh-pressure multi-stage engineering produces up to 60.5 metres of vertical elevation to prevent line starvation.\u003c\/li\u003e\n\u003cli\u003ePrecision-engineered AISI 304 stainless steel impellers and diffuser stages deliver long-term wear resistance under continuous duty.\u003c\/li\u003e\n\u003cli\u003eThe delivery header includes an 18 L membrane expansion vessel to suppress hydraulic shock and minimize unnecessary cycling.\u003c\/li\u003e\n\u003cli\u003eThe pre-plumbed parallel assembly incorporates a 125 mm suction manifold and a 125 mm discharge manifold with isolating ball valves.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty induction motors feature Class F thermal winding limits, IP54 environmental enclosure protection, and continuous S1 commercial duty.\u003c\/li\u003e\n\u003cli\u003eThe complete pumping assembly accommodates liquid temperatures from -15°C to +110°C under maximum casing pressures up to 10 bar.\u003c\/li\u003e\n\u003cli\u003eThe assembly is rigidly mounted upon a zinc-plated structural steel baseplate (S235JR) with anti-vibration damping feet.\u003c\/li\u003e\n\u003cli\u003eCalpeda Pumps Pty Ltd supports the complete pre-commissioned boosting package with a comprehensive 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\u003e3 x Calpeda MXH-F 4803 horizontal multistage pumps\u003c\/li\u003e\n\u003cli\u003e1 x Integrated I-MAT variable speed control system with triple-pump inverter regulation\u003c\/li\u003e\n\u003cli\u003e1 x Common AISI 304 stainless steel suction manifold with isolation valves (125 mm)\u003c\/li\u003e\n\u003cli\u003e1 x Common AISI 304 stainless steel discharge manifold with check valves (125 mm)\u003c\/li\u003e\n\u003cli\u003e1 x Factory-mounted 18 L membrane pressure vessel on delivery header\u003c\/li\u003e\n\u003cli\u003e2 x Digital electronic pressure transducers with M12 connection cabling\u003c\/li\u003e\n\u003cli\u003e1 x Heavy-duty zinc-plated structural steel mounting baseplate (S235JR)\u003c\/li\u003e\n\u003cli\u003e1 x Comprehensive installation manual and manufacturer documentation pack\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51531085119735,"sku":"BS3V 3MXH-F 4803-ITT*","price":67153.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs3v-3mxh-f-4803-itt-three-phase-3-x-7-5kw-variable-speed-3-pump-booster-set-i-mat-converter.png?v=1793263173","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs3v-3mxh-f-4803-itt-three-phase-3-x-7-5kw-variable-speed-3-pump-booster-set-i-mat-converter","provider":"Foundation Pumps","version":"1.0","type":"link"}
