The BS1F 1MXH 3201 booster assembly utilises a single Calpeda MXH 3201 horizontal multistage pump, supplying flow rates up to 733.3 L\/Min to serve high-demand ring mains. Up to 16.3 m of head is available to maintain steady distribution pressure.\u003c\/p\u003e\u003cp\u003eSystem responsiveness is governed by differential pressure switches with a microprocessor control board that tracks real-time hydraulic load across the distribution network. As soon as multiple fixtures open and line pressure drops to the activation threshold, the controller triggers the pump and holds it online until system pressure stabilises. Built-in delay timers and anti-cycling logic eliminate nuisance tripping caused by brief pressure transients.\u003c\/p\u003e\u003cp\u003eGenerously proportioned stainless steel AISI 304 manifolds handle high-volume water movement while keeping flow velocities and friction losses low. The suction collector features a wide 100 mm inlet connection, matched with an 80 mm delivery outlet that feeds directly into the building trunk main. Heavy-duty isolation ball valves, a positive-sealing check valve, a clear system pressure gauge, and an expansion vessel port complete the hydraulic layout.\u003c\/p\u003e\u003cp\u003eConnected to a commercial three-phase 415 V power circuit, the motor is built with a versatile three-phase 400\/690 V winding arrangement for industrial reliability. Its 2-pole induction design spins at approximately 2900 rpm (50 Hz) in accordance with IEC 60034 specifications and Class F insulation criteria, producing 4 kW (P2) of mechanical output at a full-load current draw of 5.5 A.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-Flow Hydraulic Architecture: Incorporates a 2-stage stainless steel impeller stack optimised for moving large water volumes efficiently across broad pipe networks.\u003c\/li\u003e\n\u003cli\u003eIntelligent Switch Control: Uses a dedicated microprocessor board and differential pressure switches to automate start-stop sequences and prevent rapid cycling.\u003c\/li\u003e\n\u003cli\u003eCorrosion-Proof Wet End: Constructed with AISI 304 stainless steel manifolds and pump internals to ensure long service life in potable and process water duties.\u003c\/li\u003e\n\u003cli\u003eHot and Chilled Water Ready: Handles fluid temperatures ranging from -15 °C to +110 °C, suiting both central heating circuits and chilled process lines.\u003c\/li\u003e\n\u003cli\u003eIndustrial Ingress Protection: Rated to IP54 standards to safeguard electrical terminals and motor bearings against moisture spray and airborne particulates.\u003c\/li\u003e\n\u003cli\u003eIntegrated Isolation and Check Valves: Allows technicians to isolate the pump set quickly and prevents reverse backflow when the unit enters standby.\u003c\/li\u003e\n\u003cli\u003eDiaphragm Tank Interface: Features a dedicated manifold take-off designed for seamless connection to an external buffer vessel.\u003c\/li\u003e\n\u003cli\u003ePre-Tested Assembly: Arrives fully assembled and factory verified on a structural steel frame for rapid mechanical and electrical hook-up.\u003c\/li\u003e\n\u003cli\u003eManufacturer Assurance: Backed by a 24 Months warranty covering manufacturing quality for Australian commercial installations.\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 3201 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 2000 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423233310967,"sku":"BS1F 1MXH 3201*","price":12575.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs1f-1mxh-3201-three-phase-4kw-fixed-speed-single-pump-multistage-booster-system.png?v=1793070813","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs1f-1mxh-3201-three-phase-4kw-fixed-speed-single-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
