Horizontal Centrifugal Pumps

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

Centrifugal pumps made of thermoplastic polymers.

The ranges offered are the development of several projects conceived in the 35 years of activity. Argal centrifugal pumps are designed to operate in different condition of duty , fluids pumped and type of service; can be classified into two categories, process pumps or service pumps.

Construction variants of Argal centrifugal pumps:

Mechanical sealed direct drive


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.

Sealless magnetic drive


For clean liquids or liquids moderately laden with solids, themagnetic 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.


Long coupled or Close coupled

Long coupled


With bearings housing and separate electric motor  connected by mean of elasitc coupling and bolted to a common base plate.

Close coupled


Monoblock with pump assy flange directly mated  to the flange of the motor.
