SAER IR 32-250 E - 7.5 kW, IE3, MEI > 0.4

• Pumps are monobloc and compact in design to minimize costs and dimensions.
• "Rear-pull" design: The motor unit and the rotating part of the pump can be removed without having to remove the pump body from the plant pipeline. Pump body standardized according to EN733.
• Wide range: More than 500 models available with powers from 0.37 kW to 45 kW, discharge ports from DN32 to DN150 and available in different configurations, materials and with different motors.
• Energy saving: Highly efficient hydraulic design optimized with CFD systems and with ErP-compliant performance
• IE2 and IE3 efficiency class motors that are compliant with the ErP directive, oversized and suitable for use with frequency converters as standard.
• Heavy duty design: AISI431 or Duplex stainless steel shaft, oversized ball bearings that offer reduced operating noise and long life.
• Wide selection of mechanical seals and materials for wetted parts: cast iron (standard), bronze and stainless steel castings (on request)
