ADH 110 PP/A/1.5HP/TF/2800/BSP - Horizontal Centrifugal Pump

Available in PP and PVDF Features Non-metallic mechanical seal centrifugal pumps with open impeller. Centrifugal pumps series ADH with mechanical seal are made of plastic materials (Polypropylene and PVDF) and are suitable for high corrosive liquids containing solids in suspension. 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 ADH 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 shaft that is integral with the drive shaft of the electric motor. The shaft mechanical seal is housed at the rear of the impeller. ΑDH horizontal pumps should be fitted to prevent dry running and the formation of a vortexand possible air suction. Horizontal centrifugal pumps should only operate whilst filled. -Materials in contact with the liquid: casing and impeller PP/PVDF - Flow up to 75 m3/h - Max pressure up to 38 mlc - Max temperature: PP 60°C – PVDF 90°C - Max viscosity: 500 cSt - Two different kind of mechanical seal available: lip seal and internal PTFE bellow mechanical seal for all the sizes - Upon request the pump can be supplied with flanges Motors: IP55 – F Class – 2-pole – 50 Hz – three-phase Single phase from 0,55 kw to 2,2 kw – 50/60 Hz
