Description of the pump
The CTM pumps are centrifugal, single-stage type with magnetic coupling, in close-coupled version,
made from moulded thermoplastic material.
The main feature of these pumps is the transmission of movement by means of a magnetic coupling.
The outer magnetic unit (16), connected to the motor shaft transmits torque to the inner magnetic core-
impeller group (90), the magnetic field generates impeller rotation without physical contact. The isolation
shell (12) is fitted between the two cores sealing hermetically the liquid pumped by the atmosphere,
see figure below.
