Differently centrifugal pumps,
Alifter pumps increase power
reducing capacity
Sound pressure (approx. 82 dB)
is higher in comparison with
centrifugal pumps: it is a direct
result of the operational principle

dimension notes
DN = 20 mm
Arrows on the connectioncasing show the outlet related
to the rotation
The pump is fixed to the ground
with the holes of the motor-feet
The two hydraulic connections have same dimensions
