Technical Specifications

Applications

• For clean liquids without abrasives, which are non-aggressive for the pump materials (solids content up to 0.2%).
• For water supply.
• For heating, air-conditioning, cooling and circulation plants.
• For civil and industrial applications and for agriculture.
• For firefighting applications.
• For irrigation.

Operating conditions

• Liquid temperature from -10 °C to +90 °C.
• Ambient temperature up to 40° C.
• Total suction lift up to 7 m.
• Maximum permissible working pressure up to 16 bar (10 bar per N,N4 32-12,16,20; N,N4 40-25; N,N4 50-20,25, N4 65-31, N,N4 100-250,315,400, N4 125-250,400, N4 150-400 and bronze version).
• Maximum permissible rotation speed: see table on page 32ad317a-c172-400f-958b-5c649d0cf20d

Features

• Cutting edge hydraulics: The geometry of the impeller and the pump casing are optimized to achieve maximum efficiency and the best suction capability.
• Flexible: The option to choose between cast iron and bronze materials for the hydraulic parts in contact with the pumped liquid allows N-N4 series pumps to be selected for use with different types of
  liquids.
• Robust: The mechanical structure of the hydraulic parts in contact with the pumped liquid are dimensioned to guarantee the maximum resistance to mechanical stress. Also, the casing cover is provided with wings that prevent turbulence in the area of the mechanical sea, increasing the reliability.
• Reliable: The bearing and shaft are designed to ensure the reduction of the stress, providing high reliability
  under all operating conditions.
