Product Overview
Commercial amenity blocks, gyms, and medium-density apartment complexes often demand higher volumetric flow without stepping up to three-phase electrical infrastructure. Featuring 2 Calpeda MXHLM 403 horizontal multistage pumps, the Calpeda BSM2F 2MXHLM 403 booster set supplies up to 266.6 L/Min of combined flow. Where high-pressure boosting is needed, the hydraulic stages can produce up to 30 m of head. Its dual-pump architecture guarantees consistent water delivery when multiple showers and taps operate simultaneously.
Pressure regulation across the manifold is managed by differential pressure switches with a microprocessor control board that tracks real-time demand. One pump serves as the primary duty unit during light usage, while the assist pump stages in automatically whenever high-volume draw-offs cause header pressure to dip. Automatic duty alternation rotates the lead pump after every run cycle, and anti-cycling switch calibration prevents rapid motor restarts.
Built for multi-decade life in potable and hot-water service, the skid uses hygienic stainless steel AISI 304 suction and delivery manifolds. The pipework features a 50 mm suction inlet and a 40 mm discharge outlet sized to accommodate higher flow rates with minimal head loss. Individual isolation ball valves, non-return check valves, a direct-reading system pressure gauge, and an external vessel connection port are pre-installed on the headers.
Powering the package is simple in residential and light commercial buildings because both the incoming feed and motor windings utilise single-phase 230 V electricity. Running at a nominal 2900 rpm (50 Hz), each 2-pole induction motor is rated at 0.55 kW (P2) and draws 4.5 A during full-load operation. Full adherence to IEC 60034 motor specifications and Class F winding insulation ensure dependable, low-noise performance.
Key Features
- Balanced Multistage Output: Uses a 3-stage stainless steel impeller arrangement to deliver generous flow capacity alongside steady medium-head boosting.
- Intelligent Lead-Lag Staging: Coordinates sequential pump activation and automatic duty changeover via the onboard microprocessor to equalise component wear.
- AISI 304 Stainless Manifolds: Provides corrosion-free fluid distribution across both the suction and discharge collectors for clean potable water handling.
- Hot and Chilled Liquid Support: Rated for continuous operation with fluid temperatures ranging from -15 °C to +110 °C across diverse plumbing circuits.
- Dust and Splash Guarding: Built with IP54 environmental protection to keep electrical terminals and motor housings safe in damp plant areas.
- Isolated Maintenance Access: Integrates full-bore ball valves and check valves on each branch so one pump can be serviced while the other maintains pressure.
- Stable Differential Switching: Relies on precision pressure switches with anti-cycling logic to eliminate contactor chattering and pressure surges.
- Factory Tested Dependability: Arrives pre-wired and fully tested on a rigid steel baseplate with coverage from a 24 Months warranty.
