Description

The Alfa Laval BladeClean is a fluid driven machine designed for cleaning the difficult to reach surfaces of an agitator installed

in various tanks and vessels. It is powered entirely by water and requires no electricity, compressed air or lubricant for

operation. It has minimal moving parts and works on a simple spring mechanism. The water entering through the inlet lifts a

plunger upwards against the spring force this allows a cone of water to impact the agitator. At lower pressures the plunger is

retracted by the spring, closing the flow. In the closed position the plunger is flush with the outlet which prevents any deb ris

from entering the Alfa Laval BladeClean. A positive metal stop is provided to prevent the plunger from being pushed down

when the load of material within the tank would be acting on the top of the Alfa Laval BladeClean. A complete description of the

technical specifications and construction of the stainless steel Alfa Laval BladeClean can be found ahead in the manual.
