Calpeda MXHL EI 209 Three Phase 1.5kW Variable Speed Single Pump Multistage Booster Set with I-MAT Converter

Light industrial unit complexes and commercial business estates depend on the Calpeda MXHL EI 209 booster set for consistent water delivery. Built with 1 x Calpeda MXHL 209 multistage pump assemblies, the package delivers a maximum volumetric flow rate of 80 L/min to overcome sudden demand spikes across commercial pipework. The hydraulic wet ends produce a maximum shut-off head of 97.1 metres to maintain constant vertical static elevation without line starvation.

Capable of answering sudden fixture load shifts, single pump delivery expands up to 80 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.

The structural assembly is anchored to an industrial-grade mounting baseplate. Hydraulic construction utilizes premium 316L Stainless Steel impellers, stage chambers, and pump casings for superior corrosion resistance and longevity. The 9-stage hydraulic stacks connect into common manifolds featuring a 32 mm suction port and a 25 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.

A high-efficiency electric motor runs at 2900 rpm to drive the multistage hydraulic wet end. Operating with a full-load current rating of 3.6 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.

Key Features

• An integrated motor-mounted I-MAT variable speed drive regulates rotational velocity in real time, preventing sudden pressure spikes and eliminating line water hammer.
• Calibrated hydraulic impellers smoothly generate continuous clean water delivery up to 80 L/min under site draw.
• The multistage hydraulic wet end generates up to 97.1 metres of maximum head to sustain balanced upper-floor pressure.
• Heavy-duty AISI 316L chromium-nickel-molybdenum stainless steel metallurgy ensures exceptional resistance against aggressive or treated water supplies.
• The delivery header includes an 18 L membrane expansion vessel to suppress hydraulic shock and minimize unnecessary cycling.
• Standard 32 mm suction and 25 mm discharge threaded connections facilitate straightforward integration into commercial risers.
• Motive power is delivered by two-pole three-phase electric motors operating at 2900 rpm on 400V 50 Hz power with a rated current draw of 3.6 Amps.
