Calpeda BS1V 1MXV 25-312-ITT Three Phase 2.2kW Variable Speed Single Pump Booster Set with I-MAT Converter

Large commercial premises depend on reliable boosting systems to overcome vertical static lift and friction loss. This variable-speed booster package is built around 1 Calpeda MXV 25-312 vertical multistage pump to deliver smooth and dependable hydraulic performance. Under peak water demand, the unit achieves a maximum flow rate of 75 L/Min to service multiple fixtures concurrently. When operating against closed discharge valves, the multi-stage assembly generates a maximum shut-off head of 127 m to overcome static building elevation.

Continuous line pressure stability is sustained by a motor-mounted Calpeda I-MAT frequency converter linked with an electronic pressure transducer. The variable speed drive continuously tracks pipeline pressure and modulates impeller rotational speed to match consumer draw-off in real time. Controlled acceleration and deceleration ramp profiles eliminate hydraulic water hammer, substantially reducing mechanical stresses on building pipework and valves. Integrated electronic safety functions provide automatic shut-off protection against dry running, overcurrent, and phase supply faults.

Manufactured with premium AISI 304 stainless steel, the pump casing, intermediate diffuser stages, impellers, and drive shaft provide exceptional corrosion resistance and operational durability. Hydraulic manifolds feature matching 25 mm suction and discharge ports equipped with standardized G 1" BSP threaded pipe fittings for straightforward site connection. The complete assembly mounts onto a heavy-duty AISI 304 structural baseplate, furnished with premium isolation ball valves, an inline non-return valve, an analog pressure gauge, and a factory-fitted expansion vessel.

Mechanical drive is delivered through a high-efficiency 2-pole induction motor engineered specifically for Australian three-phase 400 V (50 Hz) electrical networks. Operating smoothly at a rated speed of 2900 rpm, the electric drive generates 2.2 kW (P2) of shaft power and draws 4.7 A under full rated operational load. Heavy-duty construction ensures continuous mechanical endurance and optimal energy conversion across all daily commercial demand cycles.
