"GNOCCHI" rotary pumps are characterized by their diaphragms which are dragged by the direction of eccentric rotation by means of a flexible device into the pump chamber where suction and compression take place.
The pump chamber has a peculiar form, similar to the diaphragm's which allows the diaphragm itself, because of the eccentricity of rotation, to maintain a continuous contact point with its circumference however overtaking the open sector for the inlet and outlet of products whereas at the sides the diaphragm moves adherent to the flat body and cover surfaces, getting the constant separation between suction and delivery.
The driving shaft is supported by roller bearings protected by bi-angular seals. The qualities of these pumps are great stoutness and extreme simplicity, automatic priming, reversibility, absence of valves, widely sized inlets and outlets.
More over, these pumps can be equipped with an adjustable built-in the cover By-pass for the control of the fluid.As they can pump all kinds of liquids flowing into pipes, they have particular properties to transfers light, dense, viscous liquids.While transferring volatile products and delicate substances the passage of the product thought the pomp takes place quietly, in a calm and even flow without affecting at all the characteristics of the products because of the limited speed of rotation, the widely sized passages and the special construction system.
The "GNOCCHI" rotary pumps for their stoutness, their simple construction and for their flexible device are particular suitable to transfer dense liquids or liquids with a variable viscosity or containing clots or suspended particles.The ones to transfer easily-freezing dense liquids are constructed with cofferdam for heating.
These pumps are designed to work at low R.P.M. range, variable according to the exact coefficients determined by the characteristics of the product to be pumped.The proper materials (cast iron, bronze, stainless steel) are used in the making of these pumps which can have fixed installation or can be mounted on wheels or can be set on vehicles.
The maintenance consists only in the replacement of the bi-angular seals in case of leaks with the relative lubrification of the roller bearings.-
