Tender text

Can be used for hot-water heating systems of all kinds, industrial circulation systems, air-conditioning systems and closed cooling circuits.

Maintenance-free glandless circulation pump with threaded or flange connection, pre-selectable speed stages for power adjustment.

Equipment and function

  • Manual power adjustment with 3 speed stages
  • Pumps with 1~ motor:
    • P2 up to 90 W: internal protection against unacceptably high winding temperatures
    • P2 ≥180W: Full motor protection with thermal winding contacts in conjunction with tripping unit (optional: SK 602N/SK 622N)
  • Pumps with 3~ motor:
    • P2 up to 90 W: internal protection against unacceptably high winding temperatures
    • P2 ≥ 180 W: Full motor protection with thermal winding contacts in conjunction with tripping unit (optional: SK 602N/SK 622N)
    • Mains connection 3~, 230 V with optional switching plug
  • Cataphoretic-coated pump housing for optimal corrosion protection
  • PN 6/PN 10 combination flange (for DN 40 to DN 65)
  • Thermal insulation shell for heating applications
