Product Overview
Higher volumetric water demand across busy shower blocks, commercial kitchens, and medium-density estates calls for wider impeller passages. Driven by 1 Calpeda MXHL 403 horizontal multistage pump, the BS1F 1MXHL 403 booster assembly supplies generous flows up to 133.3 L/Min. For vertical risers and pressurised distribution lines, the pump assembly can reach up to 30 m of head. It maintains steady line pressure when multiple high-flow outlets open simultaneously across low-to-medium rise facilities.
Reliable start-and-stop automation is achieved through calibrated differential pressure switches managed by an integrated microprocessor control board. Rather than relying on raw switch closures alone, the processor enforces intelligent delay intervals that eliminate hydraulic shock and frequent motor restarts. Integrated safety interlocks monitor operating status around the clock to guard against dry-run conditions and thermal overload.
Constructed from corrosion-resistant stainless steel AISI 304 pipework, the manifold set features a 32 mm suction header and a 25 mm delivery header. Full-port isolation ball valves and a spring-check non-return valve allow straightforward pump isolation while preventing backflow depressurisation. Technicians can monitor output pressure via the mounted dial gauge and connect an external diaphragm vessel directly to the dedicated manifold port.
Taking its primary feed from a three-phase 415 V mains circuit, the unit drives a heavy-duty motor built with a three-phase 230/400 V winding rating. The 2-pole induction design rotates at approximately 2900 rpm (50 Hz) to produce 0.55 kW (P2) of output power while drawing 1.6 A under full load. Class F winding insulation and strict adherence to IEC 60034 motor standards ensure exceptional longevity.
Key Features
- High-Flow Impeller Geometry: Utilises a 3-stage stainless steel hydraulic assembly tuned for elevated volumetric flow delivery.
- Microprocessor Assisted Switching: Refines differential pressure switch signals with electronic timers to stop rapid pump cycling.
- Sanitary Stainless Manifolds: Uses AISI 304 stainless steel across headers and wetted parts to ensure clean, rust-free water transport.
- Versatile Temperature Range: Pumps chilled water or high-temperature hot water reliably from -15 °C to +110 °C.
- Protected Motor Housing: Safeguards electrical internals against dust ingress and water splashes with an IP54 ingress rating.
- Integrated Shut-Off & Check Valves: Simplifies maintenance isolation and stops reverse flow spin when the pump is idle.
- Diaphragm Tank Take-Off: Includes a pre-threaded manifold port designed for connecting an external expansion vessel.
- Pre-Wired Turnkey Skid: Ships fully assembled, wired, and factory verified to reduce on-site commissioning time.
- Backed by Calpeda Warranty: Includes a 24 Months warranty covering factory build quality and component reliability.

What factory warranty protection covers this fixed speed single pump booster assembly?
Calpeda manufacturer warranty coverage supports the Calpeda Fixed Speed Booster Set BS1F 1MXHL 403, protecting the multistage pump wet end, electric motor, and electronic control console against manufacturing defects from date of invoice.
What peak water discharge rate and maximum flow capacity does this package supply?
Water delivery capacity for the BS1F 1MXHL 403 is rated at a maximum volumetric flow of 133.3 L/min (8 m³/h) during peak demand cycles.
Which electrical power mains and automated motor control board regulate this booster set?
Operating from a three phase 400V 50 Hz electrical supply, the BS1F-1MXHL-403 is driven by a 0.55 kW two-pole induction motor and coordinated by an automated fixed-speed control panel (400V).
Under what maximum static head elevation and line pressure limits does this package operate?
Vertical water elevation reaches up to 30 metres on the BS1F 1 MXHL 403, supported by a 10 bar casing pressure threshold and fluid tolerances from -15°C to +110°C.
What corrosion proof wetted metallurgy and manifold connection thread sizes are incorporated?
Corrosion-resistant AISI 316L chromium-nickel-molybdenum stainless steel forms the wet end of the 1MXHL 403 (BS1F 1MXHL 403), which rests on a Zinc-plated Steel S235JR baseplate equipped with isolating valves and G 1 1/4 by G 1 connections.
