Cooling circuits and utility circulation systems often require consistent water movement without excessive pressure loading, particularly where continuous-duty operation is expected across compact installations. The Calpeda P18-MXHLM 402 pressure package combines a horizontal multistage stainless steel pump with an integrated 18L pressure tank to support stable clean water circulation while reducing unnecessary motor cycling during fluctuating system demand.
Flow handling reaches up to 8 m³/h with maximum head performance of 20 m, making the system suitable for moderate-pressure circulation duties, cooling water movement, and balanced utility transfer applications. The single-phase 230V motor operates with maximum input power of 0.57 kW and rated current of 3 A, providing efficient hydraulic performance where steady water movement is more critical than elevated discharge pressure.
Hydraulic operation is supported through a close-coupled multistage arrangement using closed impellers to maintain controlled flow characteristics and smooth discharge stability across continuous circulation conditions. The pump is intended for clean non-abrasive liquids compatible with stainless steel construction and incorporates threaded suction and discharge ports for direct integration into circulation pipework and compact pressure systems.
AISI 316L stainless steel hydraulic components improve resistance against corrosion in clean water applications, while ceramic alumina and carbon mechanical seal faces with EPDM elastomers support operational durability during continuous service conditions. Insulation class F and IP54 motor protection assist dependable operation, and permitted liquid temperatures range from -15°C up to +110°C according to operating conditions.
