Calpeda MXHL EI 207 Three Phase 1.1kW Variable Speed Single Pump Multistage Booster Set with I-MAT Converter

Commercial multi-storey residential developments and accommodation properties eliminate plumbing pressure dips with the Calpeda MXHL EI 207 booster set. Built with 1 x Calpeda MXHL 207 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 75.3 metres to maintain constant vertical static elevation without line starvation.

Engineered for continuous commercial duty cycles, single pump discharge reaches 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 mechanical layout rests upon a rigid, vibration-isolated structural steel mounting base. Hydraulic construction utilizes premium 316L Stainless Steel impellers, stage chambers, and pump casings for superior corrosion resistance and longevity. The 7-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.

Electrical motivation is provided by an industrial two-pole electric motor operating on 400V 50 Hz. Operating with a full-load current rating of 2.7 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

• Advanced I-MAT variable speed drives provide smooth soft-start and soft-stop acceleration to safeguard downstream mechanical pipework.
• Engineered for high-efficiency hydraulic delivery, the single multistage wet end discharges clean water volumes up to 80 L/min.
• The multistage hydraulic wet end generates up to 75.3 metres of maximum head to sustain balanced upper-floor pressure.
• All primary wetted components including pump casings, stage chambers, and impellers are fabricated from premium AISI 316L stainless steel.
• A factory-mounted 18 L membrane pressure vessel dampens line pressure surges and buffers micro-draws without starting the pumps.
