Calpeda BS2V 2MXV 80-4801-ITT 2 x 4kW Variable Speed Twin Pump Booster Set with I-MAT Converter

Commercial buildings operating extensive vertical plumbing networks require dependable line boosting to maintain steady fixture flow. This variable-speed twin package integrates 2 Calpeda MXV 80-4801 vertical multistage pumps in parallel to provide dependable line pressure. Under peak concurrent fixture demand, the synchronized twin wet ends provide a maximum delivery capacity of 2000 L/Min across the network. Against closed line valves, the synchronized hydraulic wet ends achieve a maximum static delivery head of 18 m to maintain elevated static lift.

Constant hydraulic delivery is achieved using a motor-mounted Calpeda I-MAT variable speed controller programmed for automated multi-pump management. The frequency converter adjusts motor rotational speed continuously to maintain target manifold pressure regardless of sudden fixture activations. Controlled deceleration and soft-starting profiles isolate the piping distribution network from shock loading and damaging hydraulic hammer effects. Embedded electronic safety protocols actively protect the package against low-suction dry operation, electrical supply phase faults, and excessive motor current.

Built to withstand substantial commercial system pressures, the pumps feature Cast Iron GJL 250 casings combined with AISI 304 stainless steel hydraulic stages and impellers. Common stainless steel manifolds connect the pumping assembly using 125 mm suction and 125 mm delivery ports with DN 125 flanged. Independent isolation valves and non-return valves isolate each hydraulic branch, equipped with an analog pressure gauge on an AISI 304 baseplate.

The pumping package is driven by two commercial-grade 2-pole induction electric motors engineered for three-phase 400 V (50 Hz) electrical mains in Australia. Both motors rotate synchronously at 2900 rpm, generating 2 x 4 kW of mechanical power with a combined rated full-load current draw of 2 x 8.1 Amps. Precision copper windings and Class F insulation provide exceptional thermal dissipation during continuous high-demand pumping duty.
