Where compact stainless steel centrifugal pumps are required for clean liquid handling, the Calpeda NMXL 25/70B supports utility circulation and service water movement within space-restricted installations. Its hydraulic section is manufactured in AISI 316L stainless steel for compatibility with liquids that are non-aggressive toward stainless steel materials, while the close-coupled arrangement keeps the overall assembly compact for direct installation into pipeline systems.
Hydraulic performance extends to 5.4 m³/h with maximum head reaching 18.1 m. Rotation is supplied through a three-phase 400V induction motor rated at 0.55 kW and operating at 1.7 A under rated conditions. A two-pole configuration running near 2900 rpm maintains stable liquid movement and controlled hydraulic transfer during continuous-duty operation.
Flow management is handled through a closed impeller arrangement intended for clean, non-abrasive liquids. The suction and discharge ports use threaded ISO 228/1 connections, simplifying installation into utility pipe systems without additional coupling assemblies. Ceramic alumina and carbon seal faces operate together with EPDM elastomer components, while class F insulation and IP54 enclosure protection support dependable operation under continuous service conditions.
