Calpeda MXH EI 2004 Three Phase 4kW Variable Speed Single Pump Multistage Booster Set with I-MAT Converter

Regional cultural art galleries and historic heritage museums select the quiet Calpeda MXH EI 2004 booster set for utility water feeds. Built with 1 x Calpeda MXH 2004 multistage pump assemblies, the package delivers a maximum volumetric flow rate of 400 L/min to overcome sudden demand spikes across commercial pipework. The hydraulic wet ends produce a maximum shut-off head of 64.5 metres to maintain constant vertical static elevation without line starvation.

The advanced stainless hydraulic impellers smoothly develop sustained flow rates up to 400 L/min. System regulation is controlled by an integrated motor-mounted I-MAT variable frequency drive. The pump dynamically adjusts its operating frequency to match instantaneous draw-off rates, eliminating mechanical water hammer and destructive line pressure surges. A factory-plumbed 18 L membrane pressure vessel dampens transient micro-fluctuations, while digital pressure transducers provide real-time line feedback to protect against dry running.

Designed for tough commercial environments, the assembly features a reinforced chassis. Hydraulic construction utilizes premium 304 Stainless Steel impellers, stage chambers, and pump casings for superior corrosion resistance and longevity. The 4-stage hydraulic stacks connect into common manifolds featuring a 50 mm suction port and a 50 mm delivery connection. Each individual pump line incorporates dedicated nickel-plated brass shut-off ball valves and non-return check valves mounted on a vibration-dampened S235JR steel baseplate.

Continuous motive torque is supplied by a robust two-pole induction motor operating at 2900 rpm. Operating with a full-load current rating of 5.5 Amps, the TEFC motor configuration incorporates IP54 ingress protection and Class F thermal winding insulation. The package is rated for continuous fluid temperatures from -15°C to +110°C and ambient plant room environments up to 40°C. Manufactured to strict European standards, the entire variable-speed booster system is backed by a comprehensive 24 Months manufacturer warranty.

Key Features
