Product Overview
Single-pump commercial water pressure packages require dependable hydraulic output when fixtures open across medium-sized amenities blocks and retail suites. Configured as the BSM1F 1MXHLM 403 assembly, this packaged booster unit incorporates one Calpeda MXHLM 403 horizontal multistage pump on a sturdy baseplate. The system supplies flow rates up to 133.3 L/Min when multiple outlets open across single-level and two-storey buildings. To maintain steady line pressure, the multistage hydraulics can develop up to 30 m of head.
Automated pressure switch supervision governs pump activation through differential pressure switches paired with a dedicated microprocessor control board. Whenever downstream tap usage lowers pipework pressure below the cut-in threshold, the controller brings the pump online smoothly and monitors system recovery. Built-in anti-cycling timers prevent rapid start-stop chatter during minor draw-offs, protecting mechanical seals and electrical contactors while maintaining reliable automatic stand-by readiness around the clock.
Sanitary stainless steel manifolds fabricated from AISI 304 material route incoming and outgoing water with minimal frictional loss and high corrosion resistance. Plumbers connect supply pipework to a 32 mm inlet header and distribute pressurised water through a 25 mm outlet header. Integrated isolation ball valves and non-return check valves simplify routine servicing and prevent reverse flow, while a clear pressure gauge and external vessel connection port complete the pipework.
Standard building electrical circuits feed the booster set via a single-phase 230 V supply matched directly to the motor winding configuration. Inside the drive assembly, a 2-pole induction motor spins at approximately 2900 rpm on 50 Hz mains power to deliver 0.55 kW (P2) of mechanical output. Drawing 4.5 A under full load, the motor incorporates Class F insulation and complies with IEC 60034 performance standards for continuous operation.
Key Features
- Multistage Hydraulic Design: Employs a 3-stage stainless steel impeller stack to build steady line pressure with quiet, low-vibration operation.
- Microprocessor Switch Control: Combines differential pressure switches with electronic logic to eliminate short-cycling and stabilise cut-in and cut-out behaviour.
- Hygienic Wetted Pipework: Uses AISI 304 stainless steel headers and pump internals to safeguard water purity in potable and hot-water loops.
- Broad Thermal Capability: Handles liquid temperatures spanning from -15 °C to +110 °C for chilled, ambient, or heated water transfer.
- Enclosure Weather Protection: Rated to IP54 standards to shield internal motor windings and electrical terminals against dust and water splashes.
- Serviceable Valve Architecture: Includes full-bore isolation ball valves and spring check valves so technicians can inspect components without draining the building riser.
- Direct Visual Diagnostics: Features a manifold-mounted pressure gauge and status indicators on the control panel for rapid commissioning checks.
- Commercial Build Warranty: Backed by a 24 Months manufacturer warranty covering factory assembly and component workmanship.

What peak delivery flow in litres per minute does this single phase unit supply?
Single phase plumbing installations benefit from the Calpeda Fixed Speed Booster Set BSM1F 1MXHLM 403, which discharges up to 133.3 L/min (8 m³/h) directly into building ring mains.
Which electrical power mains and automated motor control board regulate this booster set?
Electrical connection for the BSM1F 1MXHLM 403 requires standard 230V single phase power at 50 Hz, driving a 0.55 kW motor regulated by an automated fixed-speed control panel (230V).
Under what maximum static head elevation and line pressure limits does this package operate?
Total static head on the BSM1F-1MXHLM-403 reaches up to 30 metres, while pump casings withstand up to 10 bar across liquid temperatures from -15°C to +110°C.
What corrosion proof wetted metallurgy and manifold connection thread sizes are incorporated?
Fitted with AISI 316L chromium-nickel-molybdenum stainless steel impellers and chambers, the BSM1F 1 MXHLM 403 is secured to a Zinc-plated Steel S235JR baseplate and incorporates G 1 1/4 suction and G 1 discharge connections.
What manufacturer warranty protection coverage supports this fixed speed pumping assembly?
All core pumping elements of the 1MXHLM 403 (BSM1F 1MXHLM 403), including the multistage wet end, electric motor, and electronic control console, are covered by Calpeda manufacturer warranty from date of invoice.
