Building supply installations and elevated water distribution systems often require stronger discharge pressure to maintain stable outlet performance across extended pipework layouts. The Calpeda P18-MXHLM 404 pressure package combines a compact multistage hydraulic assembly with an integrated 18L pressure tank to support controlled pressure retention during changing water demand conditions.
Hydraulic capability reaches up to 40.5 m maximum head while delivering flow rates up to 8 m³/h, supporting building pressure distribution, elevated clean water transfer, and continuous supply duties where stable delivery pressure is essential. The single-phase 230V motor operates with maximum input power of 1.01 kW and rated current of 5.7 A for dependable operation across compact pressure systems.
The horizontal close-coupled multistage design uses closed impellers to maintain smooth discharge stability and balanced hydraulic efficiency under continuous operating conditions. Intended for clean non-abrasive liquids compatible with stainless steel construction, the pump incorporates threaded suction and discharge ports for simplified integration into pressure supply networks and utility distribution systems.
Hydraulic components manufactured from AISI 316L stainless steel improve resistance against corrosion in demanding clean water applications. Ceramic alumina and carbon mechanical seal faces combined with EPDM elastomers support long operating service life, while insulation class F and IP54 motor protection contribute to reliable continuous-duty performance. Liquid temperature handling ranges from -15°C up to +110°C according to operating conditions.
