Inline, Dry Running Circulation Pumps


• Vertical, single-stage volute casing type, close-coupled in-line
centrifugal pumps with closed impeller. Close-coupled by means of an
adaptor bracket with an impeller keyed directly to the specific motor
shaft extension.
• The NCL-NCLD series have a “Backpull-out” design impeller, adaptor
and motor can be extracted without disconnecting the pump body
from the piping system.
• NCL-NCLD 40-120 / 320 – 1,5
– NCL: Single Head
– NCLD: Twin Head (Double pump in one housing). The two pumps are
hydraulically separated by silent-operating valve.
– 40: Diameter nominal of the pipe connection
– 120: Nominal diameter of impeller
– 320: Dimension between inlet and outlet flange
– 1,5: Nominal motor power P2 in kW
• High-efficiency motors as standard
• High corrosion protection thanks to cataphoretic coating
• Standard condensate drainage holes in the motor housing and
• The pumps are equipped with interchangeable mechanical seals
• Fluid temperature: -20°C / +120°C
• Maximum operating pressure: 10 Bar (PN10)
• IP55 protection, insulation class F
• Mains connection 3 ~ 400V, 50 Hz
• For bigger than 0,75 kw motors, Efficiency Class IE3

Pump Housing and Lantern: Cast Iron
Impeller: Reinforced Glass PPO up to 5,5 kW (not included)
Cast Iron: 5,5 kW – 7,5 kW
Mechanical Seal: AQ1EGG
Shaft: X20Cr (AISI420)
NCL-NCLD pumps are designed for clean or slightly contaminated liquids
with low viscosity.
