Product Overview
Large-scale industrial plumbing networks and high-occupancy commercial towers require heavy-duty water boosting to keep mains distribution steady during simultaneous draw-offs. Built around the Calpeda BS2F 2MXH 4801 configuration, this twin-pump assembly pairs 2 Calpeda MXH 4801 horizontal multistage pumps to deliver combined flow rates up to 2000 L/Min. Where vertical lift is required, the multistage hydraulics can develop up to 18 m of head. Its robust hydraulic output makes it ideal for hospital wings, district amenities, and plant ring mains.
Coordinated demand response relies on differential pressure switches with a microprocessor control board that continuously tracks header pressure. As system consumption rises and pressure drops to the cut-in threshold, the lead unit starts immediately while the lag unit stages in only if heavy draw persists. Automatic duty alternation rotates the primary assignment after every cycle to equalise mechanical wear, supported by calibrated anti-cycling intervals that prevent rapid motor starts.
Water distribution across the skid is handled by corrosion-resistant stainless steel AISI 304 suction and delivery manifolds engineered to minimise friction losses at high velocity. Site pipework connects directly to a 125 mm inlet and a 100 mm outlet, with dedicated isolation ball valves and non-return check valves fitted on each pump branch for effortless servicing. An integrated system pressure gauge and an external vessel connection point complete the hydraulic assembly.
Three-phase mains power enters the control cabinet via a three-phase 415 V supply, driving heavy-duty motors wound for a three-phase 400/690 V rating. Each 2-pole induction motor operates at approximately 2900 rpm (50 Hz) and delivers 5.5 kW (P2) of shaft power while drawing 6.2 A at full load. Manufactured in strict accordance with IEC 60034 standards and protected by Class F insulation, the drive train ensures dependable continuous-duty operation.
Key Features
- Twin Multistage Hydraulics: Combines two horizontal close-coupled units with a 2-stage impeller geometry for high-volume water transfer and smooth pressure delivery.
- Microprocessor Cascade Control: Manages lead-lag pump staging and automatic duty rotation to balance running hours across both mechanical assemblies.
- Stainless Steel Manifolds: Fabricated from hygienic AISI 304 stainless steel on both suction and discharge headers to resist corrosion and maintain water quality.
- Broad Thermal Capability: Engineered to pump hot and chilled liquids reliably across a wide operating temperature range of -15 °C to +110 °C.
- Plant Room Enclosure Protection: Sealed to IP54 standards to safeguard internal electrical windings and control electronics against dust ingress and water splashes.
- Serviceable Valve Architecture: Equipped with individual shut-off ball valves and spring-loaded check valves so technicians can isolate either pump without shutting down building supply.
- Anti-Cycling Pressure Regulation: Utilises precision differential pressure switches with built-in delay timers to eliminate nuisance chattering during minor line fluctuations.
- Factory Tested Assurance: Supplied as a pre-wired, pressure-tested skid assembly backed by a comprehensive 24 Months manufacturer warranty.
