Continuous clean water transfer systems require stable circulation performance and reliable pressure retention during sustained operating periods. The Calpeda P18-MXHLM 405 pressure package integrates an 18L pressure vessel with a compact horizontal multistage pump to support uninterrupted clean water movement across utility distribution and circulation applications.
Performance reaches up to 52 m maximum head with flow handling up to 8 m³/h, allowing the system to maintain dependable delivery pressure across transfer lines, circulation loops, and connected supply networks. A single-phase 230V motor operating with maximum input power of 1.44 kW and rated current of 7.4 A supports continuous-duty service where stable hydraulic output is required.
Flow generation is achieved through a multistage close-coupled hydraulic arrangement incorporating closed impellers for balanced discharge characteristics and controlled hydraulic efficiency. The pump is intended for clean non-abrasive liquids compatible with stainless steel construction and incorporates threaded inlet and outlet ports for straightforward installation into circulation and pressure transfer systems.
AISI 316L stainless steel hydraulic components improve corrosion resistance under continuous clean water operating conditions. Mechanical sealing is supported through ceramic alumina and carbon seal faces with EPDM elastomers, while insulation class F and IP54 motor protection contribute to reliable long-duration operation. Permissible liquid temperatures range from -15°C to +110°C depending on installation conditions.
