The volumetric self-priming close coupled pump, range VMA has been designed to load-unload basins, tank-trucks, tanks where is no possible the flooded installations. Reversible and easy to handle, the VMA pumps can prime from negative suction head of max 4 meters without the necessity to feel the priming chamber the first time.<\/p>

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.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
