Product Overview
Low-rise apartment buildings, medical clinics, and commercial kitchens frequently encounter fluctuating mains pressure that disrupts fixtures on upper levels. Configured as the Calpeda BSM2F 2MXHLM 204 booster set, this twin-pump system combines 2 Calpeda MXHLM 204 horizontal multistage pumps to deliver flows up to 160 L/Min. Up to 42.5 m of head is available to maintain line pressure across elevated risers. Its extra vertical lift ensures crisp shower and tap performance across taller plumbing zones.
Automated pressure management is achieved through differential pressure switches with a microprocessor control board that coordinates both pumps seamlessly. During normal daytime draw, a single duty pump satisfies system demand, conserving energy while holding the second unit in reserve for peak load events. Every start sequence triggers automatic duty alternation to keep bearings and mechanical seals in prime condition, backed by anti-cycling delays that stabilise switching behaviour.
Hygienic fluid handling starts with precision-welded stainless steel AISI 304 suction and delivery manifolds mounted directly to the base frame. Installers are provided with a 50 mm common inlet and a 40 mm discharge outlet sized to maintain smooth laminar flow. Serviceability is built into the pipework via individual isolation ball valves, non-return check valves, an integrated system pressure gauge, and a ready-made port for attaching an external expansion vessel.
Installation is simplified on sites with standard power availability because both the electrical feed and motor windings are rated for single-phase 230 V operation. Running at a synchronous nominal speed of 2900 rpm (50 Hz), each 2-pole induction motor produces 0.55 kW (P2) of mechanical power and draws 4.5 A under full load. Class F thermal insulation and strict adherence to IEC 60034 standards safeguard the motors during continuous operation.
Key Features
- Elevated Head Generation: Employs a 4-stage stainless steel hydraulic assembly to provide higher discharge pressure for multi-level plumbing layouts.
- Microprocessor Cascade Logic: Brings the assist pump online automatically when demand spikes and alternates lead duty to prevent uneven mechanical wear.
- Potable-Grade Manifold Pipework: Built with AISI 304 stainless steel headers and internal wet-end components to ensure clean, rust-free water delivery.
- Extended Temperature Resilience: Capable of handling cold and hot water applications effortlessly with a liquid rating from -15 °C to +110 °C.
- Weather and Dust Shielding: Engineered with IP54 enclosure protection to defend the control board and motor windings against damp utility environments.
- Maintenance-Friendly Valving: Outfitted with dedicated shut-off ball valves and non-return valves so either pump can be removed while the partner unit remains active.
- Anti-Chatter Switch Control: Uses reliable differential pressure switches paired with electronic timers to eliminate rapid on-off cycling during minor leaks or drips.
- Commission-Ready Package: Supplied fully wired and hydrostatically tested at the factory with the peace of mind of a 24 Months warranty.
