• Protection class IP 54
Equipment/function
• 1 to 2 pumps per system
• Components that come in contact with
fluid are corrosion-resistant
• Galvanised base frame with heightadjustable
vibration dampers for
insulation against structure-borne noise
• Pipework in stainless steel 1.4571
• Gear-operated shut-off ball cock/
annular shut-off valve on every pump,
on suction and pressure sides
• Non-return valve, on pressure side
• Diaphragm pressure vessel 8 l, PN 16, on
pressure side
• Pressure sensor, on discharge side
• Comes as standard with pump
protection by means of minimum
volume acceptance via bypass switch
without auxiliary energy.
Special features
• Compact system in accordance with all
requirements of DIN 1988

centrifugal pumps Helix V series with
IE2 motors
• Variants
–Single-pump system
–Twin-pump system with two
independent single-pump systems in
a base frame
• Comes as standard with pump
protection by means of minimum
volume acceptance via bypass switch
without auxiliary energy.
