Product Overview
Medium-rise residential complexes, guesthouses, and light industrial washdown bays require substantial vertical lift without exceeding standard single-phase power limits. The Calpeda BSM2F 2MXHLM 205 twin-pump booster meets this challenge by pairing 2 Calpeda MXHLM 205 horizontal multistage pumps, developing up to 53.5 m of head for vertical risers. When multiple fixtures open at once, combined flow capacity reaches up to 160 L/Min. Having two identical pumps on a single skid guarantees built-in redundancy and steady pressure at elevated outlets.
System pressure is held within tight operating bands by differential pressure switches with a microprocessor control board that governs pump staging. Whenever water usage exceeds the capacity of the primary unit, the controller brings the lag pump into service automatically to maintain line pressure. After each demand cycle concludes, automatic duty alternation swaps the lead assignment between pumps, while anti-cycling parameters prevent short-cycling across the pressure switches.
Clean, durable fluid conveyance is ensured by stainless steel AISI 304 suction and delivery headers that resist corrosion and thermal stress. The manifold geometry incorporates a 50 mm suction connection and a 40 mm delivery connection for rapid plant room hook-up. Full-bore isolation ball valves and non-return check valves on each branch protect against backflow, complemented by a clearly visible pressure gauge and a tapping point for an external diaphragm tank.
Site wiring is straightforward since the control panel supply and motor windings share a unified single-phase 230 V specification. Each close-coupled 2-pole induction motor operates at roughly 2900 rpm (50 Hz), delivering 0.75 kW (P2) per pump with a rated current draw of 5.7 A. Constructed to IEC 60034 performance standards and equipped with Class F insulation, the motor assemblies handle frequent daily starts with exceptional thermal stability.
Key Features
- High-Head Multistage Design: Features a precision 5-stage impeller configuration that builds strong vertical pressure for taller buildings and long pipe runs.
- Automatic Duty Rotation: Cycles the lead and lag roles via the microprocessor board so neither pump sits idle or suffers disproportionate wear.
- All-Stainless Fluid Path: Combines AISI 304 stainless steel manifolds and pump bodies to maintain hygienic conditions in domestic and commercial water loops.
- Hot-Water Ready Construction: Operates dependably across liquid temperatures ranging from -15 °C to +110 °C for both heating and potable distribution.
- Robust Environmental Sealing: Protected to IP54 standards against dust particles and splashing water commonly encountered in basement plant rooms.
- Individual Pump Isolation: Includes dedicated ball valves and check valves on both branches, allowing routine servicing without interrupting building water supply.
- Responsive Pressure Switching: Pairs mechanical differential pressure switches with electronic logic to deliver smooth cut-in and cut-out transitions.
- Factory Verified Quality: Shipped pre-assembled and tested on a sturdy baseplate, backed by a comprehensive 24 Months manufacturer warranty.
