Calpeda MXHL EI 807 Three Phase 3kW Variable Speed Single Pump Multistage Booster Set with I-MAT Converter

Cold-storage logistics depots and agricultural distribution warehouses utilize the Calpeda MXHL EI 807 booster set for ring main pressure. Built with 1 x Calpeda MXHL 807 multistage pump assemblies, the package delivers a maximum volumetric flow rate of 217 L/min to overcome sudden demand spikes across commercial pipework. The hydraulic wet ends produce a maximum shut-off head of 83.5 metres to maintain constant vertical static elevation without line starvation.

Built to overcome vertical static riser resistance, the single pump configuration outputs up to 217 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.

All mechanical elements are securely arranged on a heavy-gauge mounting platform. 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 40 mm suction port and a 32 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 heavy-duty electric motor is engineered specifically to handle continuous inverter duty cycling. 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.
