process & systems division > mechanical diaphragm pumps with spring return mechanism The D Exacta Series is the result of many years experience acquired by SEKO BONO EXACTA in many application fields. Economical and reliable, with mechanical actuated diaphragm, this series is an ideal solution for industrial applications where chemicals have to be pumped safely at low pressure. A very low maintenance is one of the main reason to chose this models. The D Exacta Series pumps adopt the principle of the eccentric with spring return to control the stroke variation and therefore the dosing of the pumped...

innovation > technology > future Diaphragm dosing pumps are especially used where pressures are limited within 10 bar. The diaphragm used in our pumps is the result of research and development, in order to obtain the best volumetric capacity with the varying of pressure. The result optained is an optimal capacity and a long life span of the diaphragm itself. Just one model with different stroke lengths and diaphragm diameters, covers a flow rate up to 460 l/h. This kind of pumps with no leakages or fluid loss, are particularly oriented in keeping a better environmental condition on site. The...
