Centrifugal pumps made of thermoplastic polymers

In traditional pumps with mechanical drive the impeller is fixed on the extension of the motor shaft and the sealing between the pump body and the motor is obtained by the sliding rings of the mechanical seal. This construction mostly applies to liquids laden with solids in suspension for friction is limited to the sliding faces of the mechanical seal.

Mechanical sealed or sealless pumps made of different materials to provide the right answer to different users' demand.

For clean liquids or liquids moderately laden with solids, the magnetic drive is preferred for the impeller sealed into the casing  prevents any loss of liquid.

Drive is provided  by the magnetic link existent between the permanent magnets embedded in the impeller and the permanent magnets carried  by the magnet drive essay (  drum external to the casing ) that rotates at the speed of the  the shaft of the electric motor to which is mechanically mated to.
