Product Overview
Sustaining strong header pressure across expansive multi-storey precincts, manufacturing plants, and commercial complexes calls for a high-capacity twin booster set. Equipped with 2 Calpeda MXH 4802 horizontal multistage pumps, the BS2F 2MXH 4802 package generates up to 2200 L/Min of full-load flow. To overcome static elevation and pipe friction, the wet end can generate up to 35.3 m of head. This dual-pump arrangement ensures uninterrupted water delivery even when peak facility usage places heavy demand on the main riser.
Sequential pump activation is governed by differential pressure switches with a microprocessor control board mounted directly on the frame. Rather than running both motors unnecessarily during light draw-offs, the controller engages a single unit first and brings the standby pump online only when line pressure continues to fall. Built-in duty changeover logic alternates the lead role between starts, while anti-cycling switch calibration protects contactors from premature wear.
Twin suction and discharge collectors are precision-fabricated from hygienic stainless steel AISI 304 to withstand demanding thermal and hydraulic loads. Facility plumbers interface with a generous 125 mm suction port and a 100 mm delivery port designed to keep flow velocities stable. Individual isolation ball valves and non-return valves on every branch allow isolated maintenance, complemented by a clear pressure gauge and a dedicated port for an external accumulator vessel.
Connecting directly to a standard commercial three-phase 415 V power feed, the booster set drives motors specified with a three-phase 400/690 V winding rating. Every 2-pole induction drive spins at a nominal 2900 rpm (50 Hz), producing 5.5 kW (P2) of mechanical output and drawing 6.2 A per unit. Full compliance with IEC 60034 motor benchmarks and resilient Class F thermal insulation provide long-term electrical stability under sustained plant room duty.
Key Features
- High-Flow Impeller Design: Incorporates a precision 2-stage stainless steel hydraulic assembly that maximises volumetric output while keeping axial thrust balanced.
- Automated Duty Sharing: Alternates the primary and assist roles automatically through the microprocessor board to ensure even wear across both pumps.
- Corrosion-Proof Headers: Uses AISI 304 stainless steel manifolds throughout the fluid path to prevent rust contamination in potable and process water loops.
- Hot and Cold Fluid Rating: Handles media temperatures spanning from -15 °C to +110 °C, making the skid suitable for chilled circuits and hot-water boosting alike.
- Industrial Ingress Guarding: Rated to IP54 protection levels to shield motor internals and switchgear from airborne particulates and moisture spray.
- Independent Branch Isolation: Pairs heavy-duty ball valves with non-return check valves on each pump leg to prevent backflow and simplify mechanical servicing.
- Stable Pressure Switching: Relies on calibrated differential pressure switches to maintain consistent cut-in and cut-out bands without rapid motor short-cycling.
- Turnkey Skid Reliability: Delivered fully assembled and factory verified on a rigid baseplate with the backing of a 24 Months warranty.

How much collective peak water flow can this high capacity twin pump package deliver?
High-volume industrial water infrastructure depends on the Calpeda Fixed Speed Booster Set BS2F 2MXH 4802, which yields a collective peak rate of 2200 L/min (132 m³/h).
Which electrical power mains and automated motor control board regulate this booster set?
Dual two-pole induction motors totaling 11 kW propel the BS2F 2MXH 4802 on a 400V three phase 50 Hz supply managed by an automated fixed-speed sequencing control panel (400V).
Under what maximum static head elevation and line pressure limits does this package operate?
Capable of lifting water up to 35.3 metres of total head, the BS2F-2MXH-4802 conforms to a 10 bar maximum casing limit and operates between -15°C to +110°C.
What corrosion proof wetted metallurgy and manifold connection thread sizes are incorporated?
Constructed with dual AISI 304 chromium-nickel stainless steel multistage pumps, the BS2F 2 MXH 4802 is seated on a Painted Steel S235JR baseplate with isolating valves and DN 125 Flanged inlet with DN 100 Flanged outlet manifolds.
What manufacturer warranty protection coverage supports this fixed speed pumping assembly?
Protection for the 2MXH 4802 (BS2F 2MXH 4802) is secured by Calpeda manufacturer warranty coverage guarding the pump wet end, electric motor assembly, and control console against defects from date of invoice.
