MORE INFORMATION

  Data sheet NX/BX

2-poles NX pump range 2,900 rpm, 50 Hz

4-poles NX pump range 1,450 rpm, 50 Hz

• Identical hydraulics, chambering, mechanical seal, connection dimensions such as the chemical standardized pump NX
• Hollow shaft with its own massive bearing guarantees longest life time and can be combined with any standard flange motor (also ATEX)
• The design of the BX permits replacement of wear parts without disconnecting the pump casing/pipeline connection
• Compact design without base plate installation and alignment of the coupling system possible

• Clean chemicals
• Wetted parts:
  • PP-H (also conductive)
  • PVDF (also conductive)
• Max. application range: 
  • Capacity up to 235 m³/h
  • Delivery head up to 68 m
