Product Overview
Winery cellar doors and regional tasting facilities stabilize bathroom and kitchen feeds with the Calpeda MXH EI 1604 booster set. Built with 1 x Calpeda MXH 1604 multistage pump assemblies, the package delivers a maximum volumetric flow rate of 367 L/min to overcome sudden demand spikes across commercial pipework. The hydraulic wet ends produce a maximum shut-off head of 46.5 metres to maintain constant vertical static elevation without line starvation.
Configured for demanding continuous duties, aggregate single-unit delivery expands up to 367 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.
Plant room pipework stress is mitigated by an integrated structural mounting baseplate. 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 40 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.
The drive motor complies with strict international energy efficiency and operational reliability standards. Operating with a full-load current rating of 6.6 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.
