Utilising a single Calpeda MXH 1605 horizontal multistage pump, this packaged plant achieves flows up to 416.7 L\/Min. For vertical risers and pressurised distribution lines, the pump assembly can reach up to 57.5 m of head. It excels in central hot-water recirculation, process cooling, and multi-floor potable supply networks.\u003c\/p\u003e\u003cp\u003eControl accuracy comes from differential pressure switches with a microprocessor control board that supervises system demand around the clock. As fixture draw lowers line pressure past the activation threshold, the electronic board initiates pump operation and sustains run status until target pressure stabilizes. Intelligent anti-cycling logic prevents erratic switching caused by minor pressure dips, extending the service life of both mechanical seals and motor contactors.\u003c\/p\u003e\u003cp\u003eAll manifold pipework is constructed from durable stainless steel AISI 304, featuring a 50 mm suction header and a 40 mm discharge manifold sized to prevent cavitation and velocity loss. Full-bore isolation ball valves and positive-sealing check valves are factory fitted to simplify routine maintenance and block reverse flow. An onboard pressure gauge gives instant visual verification, while a manifold port accommodates an external diaphragm tank.\u003c\/p\u003e\u003cp\u003eEngineered for heavy-duty three-phase 415 V electrical infrastructure, the booster motor features a three-phase 400\/690 V winding rating suitable for industrial power distribution. Its 2-pole induction design runs at 2900 rpm (50 Hz) in accordance with IEC 60034 specifications and incorporates Class F insulation for superior heat tolerance. Producing 4 kW (P2) of mechanical power, the motor draws a modest 5.5 A under full duty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeavy-Duty Multistage Hydraulics: Features a 5-stage stainless steel impeller stack engineered for sustained high-pressure water delivery.\u003c\/li\u003e\n\u003cli\u003eMicroprocessor Control Architecture: Pairs precision differential pressure switches with digital delay timers to eliminate short-cycling.\u003c\/li\u003e\n\u003cli\u003eCorrosion-Proof AISI 304 Headers: Welded stainless steel suction and delivery manifolds maintain water purity and structural integrity.\u003c\/li\u003e\n\u003cli\u003eExtreme Temperature Versatility: Safely pumps chilled or heated liquids across an operating span of -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003eRobust Enclosure Sealing: Built to IP54 ingress standards with Class F winding insulation to withstand demanding plant room environments.\u003c\/li\u003e\n\u003cli\u003eMaintenance-Ready Valving: Includes integrated isolation ball valves and non-return valves for effortless pump servicing and backflow protection.\u003c\/li\u003e\n\u003cli\u003eDiaphragm Accumulator Port: Pre-configured manifold connection supports rapid tie-in to an external expansion tank for pressure buffering.\u003c\/li\u003e\n\u003cli\u003eTurnkey Quality Assurance: Fully assembled and tested at the factory and backed by 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\u003e1 x Calpeda MXH 1605 horizontal multistage pump\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 1000 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423232753911,"sku":"BS1F 1MXH 1605*","price":10679.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs1f-1mxh-1605-three-phase-4kw-fixed-speed-single-pump-multistage-booster-system.png?v=1793070799","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs1f-1mxh-1605-three-phase-4kw-fixed-speed-single-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
