Product Overview
Supplying high-flow water networks across hospitals, processing facilities, and large apartment complexes calls for a heavy-duty twin booster station. Combining two horizontal multistage Calpeda MXH 1603 pumps on a unified frame, the BS2F 2MXH 1603 package delivers up to 833.4 L/Min of flow. For demanding vertical distribution, the multistage design can build up to 34 m of head. Operating in tandem, the twin pumps handle surge draw-offs effortlessly while providing built-in mechanical redundancy.
Demand-based pump activation is governed by calibrated differential pressure switches feeding signals to a central microprocessor control board. Under normal building load a single pump maintains line pressure, while heavier simultaneous draw triggers the second pump to stage online smoothly. Automatic duty alternation swaps the lead role between cycles to balance wear, and anti-cycling delays protect the switchgear from rapid hunting.
To handle elevated flow rates cleanly, both the suction and discharge manifolds are fabricated from heavy-gauge stainless steel AISI 304. Incoming water enters through an 80 mm inlet header and exits via a 65 mm delivery manifold fitted with a system pressure gauge and an external expansion vessel tee. Each pump branch incorporates isolation ball valves and non-return check valves for backflow prevention and live servicing.
Electrical drive power relies on a three-phase 415 V mains circuit supplying industrial motors rated for three-phase 230/400 V operation. Turning at 2900 rpm on 50 Hz power, each 2-pole induction motor delivers 1.8 kW (P2) of output power and draws 4.8 A at full load. Built to IEC 60034 standards with Class F winding insulation, the motors ensure long-term thermal stability.
Key Features
- Three-Stage High-Flow Design: Features a 3-stage hydraulic assembly in both pumps to combine high volumetric flow with dependable mid-range head.
- Microprocessor Cascade Control: Monitors differential pressure switches to bring the lag pump online automatically during peak consumption.
- Automatic Duty Rotation: Alternates the lead and lag pump sequence after every cycle to equalise bearing and seal wear.
- Stainless Steel Wet Path: Uses AISI 304 stainless steel across the pump hydraulics and manifolds to prevent rust and preserve water hygiene.
- Hot and Cold Water Capability: Accommodates liquid temperatures from -15 °C to +110 °C for diverse HVAC, process, and potable applications.
- Individual Pump Isolation: Equips each branch with shut-off ball valves and non-return valves so one pump can operate while the other is serviced.
- Industrial Ingress Protection: Sealed to IP54 standards against plant-room moisture and dust, paired with Class F motor insulation.
- Pre-Tested Skid Assembly: Delivered factory assembled and tested on a rigid base with pre-wired controls and a pressure gauge.
- Two-Year Commercial Warranty: Supported by a 24 Months manufacturer warranty for assured reliability.
