Peace of Mind
Product Overview
Regional accommodation properties, multi-unit residential developments, and light commercial amenities need dependable pressure boosting that operates on standard building power. Engineered around the Calpeda BSM2F 2MXHLM 203 platform, this compact dual-pump station utilises 2 Calpeda MXHLM 203 horizontal multistage pumps to supply up to 160 L/Min of flow. When boosting water to upper floors, the system can develop up to 31 m of delivery head. The twin arrangement provides complete peace of mind for hot and cold potable water risers.
Intelligent staging across both pumps is directed by differential pressure switches with a microprocessor control board that responds smoothly to changing tap usage. When a fixture opens, the primary pump handles routine demand on its own, while the secondary unit steps in automatically during simultaneous peak draw-offs. Alternating the lead pump after each operating cycle prevents stagnation and equalises seal wear, while anti-cycling logic stops rapid starting and stopping.
All wetted manifold pipework is constructed from durable stainless steel AISI 304 to preserve water purity and resist internal scaling. The header assembly features a 50 mm suction inlet paired with a 40 mm discharge outlet for straightforward integration into building plumbing. Each pump leg incorporates dedicated isolation ball valves and non-return check valves, alongside an easy-to-read system pressure gauge and a pre-fitted connection point for an external diaphragm tank.
Designed for sites without three-phase infrastructure, both the incoming supply and the motor windings operate on single-phase 230 V power. Each 2-pole induction motor runs at approximately 2900 rpm (50 Hz), delivering a compact 0.37 kW (P2) output while drawing just 3 A per unit. Built to IEC 60034 engineering specifications with Class F winding insulation, these drives offer quiet, energy-conscious performance across extended daily duty cycles.
Key Features
- Multistage Hydraulic Efficiency: Utilises a 3-stage stainless steel impeller stack to generate smooth, pulse-free pressure boosting for smaller commercial and residential systems.
- Smart Lead-Lag Alternation: Rotates duty and standby assignments automatically via the microprocessor controller so both pumps accumulate balanced operating hours.
- Hygienic Stainless Construction: Features AISI 304 stainless steel suction and delivery manifolds plus pump casings for superior corrosion resistance.
- Wide Thermal Operating Window: Safely transfers heated or chilled water across a broad liquid temperature spectrum from -15 °C to +110 °C.
- Protected Electrical Enclosure: Constructed to IP54 ingress standards to keep moisture splashes and plant room dust away from sensitive electrical components.
- Built-In Backflow Prevention: Includes spring check valves and full-bore isolation ball valves that stop reverse flow and allow servicing without draining the riser.
- Precision Pressure Sensing: Employs pre-calibrated differential pressure switches that maintain steady line pressure while preventing nuisance motor cycling.
- Pre-Assembled Assurance: Arrives factory tested on a unified skid frame and supported by a 24 Months warranty for hassle-free commissioning.
