These mechanically Actuated Dosing Pumps are driven by worm gears, motor, drive shaft, eccentric and piston. These dosing pumps do not have any fluid between their secondary diaphragm and the primary diaphragms. Hence, they cannot spoil or ruin a product due to barrier fluid contaminating the process. These Mechanically Actuated Dosing Pumps are generally used for water and waste water treatment chemicals. In addition, these dosing pumps also have PTFE coated diaphragm which is motor driven.
