Solidity and reliability 

The volumetric self-priming pump with elastic coupling, range VGA has been designed to load-unload basins, tank-trucks, tanks where is no possible the flooded installations. Reversible and easy to handle, the VGA pumps can prime from negative suction head of max 4 meters without the necessity to feel the priming chamber the first time. Easy to handle, the pumps of this range have strong construction, produced in their components with high thickness to give a product with the maximum reliability. The electric motor is connected to the pump through elastic coupling with spacer, fixed on a carbon steel base plate. Suitable to transfer low viscosity acids and basic liquids, the internal part in contact with liquid are totally built in thermoplastic (PP-PVDF-PVC), the gaskets and the impeller blades are in a suitable material (EPDM). Standard are installed lip seals in EPDM or FPM. 

 
 
 

Exercise temperatures and materials

MATERIALS SELECTION 
The materials used in the production of our pumps, are carefully selected based upon the pumped liquids. Each material used must answer at mechanical and chemical characteristics in order to grant the best reliability of the pump. The working temperature is a really important condition, especially because the thermoplastics are materials very sensible to low and high temperatures.  



Performances

PUMPS SELECTION 
Pumps are selected based on the data transmitted from the Customer. Capacity Q, head H, suction head, specific gravity and liquid viscosity, temperature, they are required in order to proceed to the correct pump choice.
