Built with 1 x Calpeda MXH-F 4803 multistage pump assemblies, the package delivers a maximum volumetric flow rate of 1000 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 smooth motor velocity regulation, total line discharge capacity from the unit extends up to 1000 L\/min. System regulation is controlled by an integrated motor-mounted I-MAT variable frequency drive. The pump dynamically adjusts its 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 skid package is supported by a reinforced structural mounting 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 80 mm suction port and a 80 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 electrical power assembly utilizes an industrial-grade induction motor engineered for inverter regulation. Operating with a full-load current rating of 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\u003eEngineered for high-efficiency hydraulic delivery, the single multistage wet end discharges clean water volumes up to 1000 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\u003eAll primary hydraulic components including pump casings, stage chambers, and impellers are manufactured from robust AISI 304 stainless steel.\u003c\/li\u003e\n\u003cli\u003eSystem line pressure is stabilized by an 18 L membrane vessel paired with electronic pressure transducers for active dry-run protection.\u003c\/li\u003e\n\u003cli\u003ePrecision-machined 80 mm suction and 80 mm discharge ports allow clean, direct coupling to facility pipework.\u003c\/li\u003e\n\u003cli\u003eHigh-efficiency commercial electric motors run at 2900 rpm on 400V 50 Hz mains, drawing an absorbed current of 8.3 Amps.\u003c\/li\u003e\n\u003cli\u003eVerified operating limits safely tolerate fluid temperatures from -15°C to +110°C in plant room ambient conditions up to 40°C.\u003c\/li\u003e\n\u003cli\u003eIntegrated microprocessor controls protect the pumping assembly against dry running, motor overcurrent, and supply phase loss.\u003c\/li\u003e\n\u003cli\u003eFactory quality assurance is reinforced by an official 24 Months warranty covering the pump wet ends, motors, and inverter drives.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1 x Calpeda MXH-F 4803 horizontal multistage pump\u003c\/li\u003e\n\u003cli\u003e1 x Motor-mounted I-MAT variable frequency inverter drive\u003c\/li\u003e\n\u003cli\u003e1 x Common AISI 304 stainless steel suction manifold with isolation valves (80 mm)\u003c\/li\u003e\n\u003cli\u003e1 x Common AISI 304 stainless steel discharge manifold with check valves (80 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":51530926883063,"sku":"MXH-F EI 4803*","price":16481.3,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-mxh-f-ei-4803-three-phase-7-5kw-variable-speed-single-pump-multistage-booster-set-i-mat-converter.png?v=1793263173","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-mxh-f-ei-4803-three-phase-7-5kw-variable-speed-single-pump-multistage-booster-set-i-mat-converter","provider":"Foundation Pumps","version":"1.0","type":"link"}
