ADH Horizontal Centrifugal pumps
ADH Series centrifugal pumps with mechanical seal are made of plastic materials (Polypropylene and PVDF) and are suitable for high corrosive liquids. They are operated by a direct-drive motor (max 3000 rpm). Their special open-impeller design allows pumping even with very dirty liquids having apparent viscosity up to 500 cps (at 20°C) and small suspended solids. There are two versions available with different internal mechanical seal depending on use, A (lip seal) and B (bellows seal).

Description of the Pump
Resin-encased horizontal centrifugal pumps feature a solid pump casing and a lantern for connecting the electric motor and inspection of the mechanical seal. The open impeller is fitted to the pump shaſt that is integral with the drive shaſt of the electric motor. The shaſt mechanical seal is housed at the rear of the impeller.
How it works
The impeller is integral with the shaſt and direct drive electric motor and is rotated at a preset speed with the centrifugal effect producing suction on the intake side and discharge on the delivery side.
