Calpeda BS2V 2MXV 32-510-ITT 2 x 2.2kW Variable Speed Twin Pump Booster Set with I-MAT Converter

Commercial water distribution networks and multi-storey facilities rely on continuous line pressure to support multi-point fixture demand. This variable-speed twin package integrates 2 Calpeda MXV 32-510 vertical multistage pumps in parallel to provide dependable line pressure. During peak facility draw, the dual-pump set delivers a peak volumetric flow rate of 267 L/Min to supply all fixtures concurrently. Operating against closed pipework, the multistage wet ends produce a maximum shut-off head of 104 m to overcome static building elevation.

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.

Superior fluid purity and corrosion resistance are ensured through complete AISI 304 stainless steel hydraulic construction covering the pump bodies, stages, and impellers. Common stainless steel manifolds align the dual pumps with standardized 50 mm suction and 50 mm discharge connections with G 2" BSP. Each hydraulic branch incorporates nickel-plated isolation valves and non-return valves, complemented by a delivery 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 2.2 kW of mechanical power with a combined rated full-load current draw of 2 x 4.7 Amps. Precision copper windings and Class F insulation provide exceptional thermal dissipation during continuous high-demand pumping duty.
