Product Overview
Busy commercial pipework and multi-residential amenities require dependable pressure management, a challenge met effortlessly by the Calpeda BSM2F 2MXHLM 803 booster assembly. Built around two horizontal multistage Calpeda MXHLM 803 pumps mounted on a unified base, this twin-pump system supplies up to 433.4 L/Min of combined flow. Where vertical lift is required, the multistage hydraulics can develop up to 32 m of head. Its balanced hydraulic profile ensures showers, plant rooms, and commercial risers maintain consistent water delivery during peak usage.
System automation relies on differential pressure switches paired with a dedicated microprocessor control board to coordinate pump operation smoothly. When downstream water consumption increases beyond the capacity of a single unit, the controller brings the second pump online in a staged cascade sequence. Automatic duty alternation swaps the lead pump on successive cycles to equalise mechanical wear across both assemblies, while anti-cycling logic prevents rapid starting and stopping during minor pressure fluctuations.
Internal skid piping is handled by corrosion-resistant AISI 304 stainless steel suction and delivery manifolds engineered for hygienic durability. The intake header provides a 65 mm inlet connection while the discharge side terminates in a 50 mm outlet port, minimising friction losses through the pipework. Dedicated isolation ball valves and non-return check valves on each pump branch allow maintenance without shutting down the entire riser, complemented by a pressure gauge and external vessel connection port.
Single-phase mains power enters via a single-phase 230 V feed that drives both heavy-duty 2-pole induction motors directly. Operating at a nominal speed of 2900 rpm on a 50 Hz frequency, each motor delivers 1.1 kW (P2) of mechanical shaft output while drawing a rated current of 7.4 A under full load. Manufactured in strict accordance with IEC 60034 standards and equipped with Class F winding insulation, the drive assemblies support continuous thermal stability.
Key Features
- Twin-Pump Redundancy: Dual horizontal multistage pumps operate in duty-assist configuration to preserve water supply during peak demand or routine servicing.
- Precision Impeller Geometry: Constructed with a 3-stage stainless steel hydraulic end that maintains smooth, quiet pressure generation across varying flow rates.
- Microprocessor Cascade Control: Coordinates differential pressure switches to stage pumps sequentially and alternate lead duty automatically.
- Hygienic Stainless Headers: AISI 304 suction and delivery manifolds resist internal corrosion and preserve potable water quality.
- Broad Thermal Capability: Engineered to pump hot and chilled liquids reliably across a wide temperature spectrum from -15 °C to +110 °C.
- Environmental Enclosure Protection: Motor housings are sealed to IP54 standards with Class F insulation to guard against plant-room dust and moisture splashes.
- Serviceable Valve Architecture: Individual isolation ball valves and non-return valves allow either pump to be isolated for maintenance without system drainage.
- Turnkey Factory Verification: Delivered as a pre-wired, hydrostatically tested package backed by a 24 Months manufacturer warranty.
