Pumps, valves and fluid meters.

 Dosing pumps are positive displacement pumps. They generate constant flow rates irrespective of the head of the system. They are mainly used for chemical dosing in different process industries like food industries, water treatment industries, chemical industries etc. we can even change the flow rate using the potentiometer knob provided on it and set it to certain flow rate of the fluid to be dosed. Dosing pumps are made using different configurations of internal mechanism and each has its pros and cons. These are the following configurations of the dosing pumps. 1. Reciprocating dosing pump/metering pump  This pump uses a piston or plunger that moves back and forth (reciprocates) within a cylinder. It is a classic example of a positive displacement pump where the movement of the piston creates a vacuum to draw liquid in through the suction valve and then pushes it out through the discharge valve at high pressure.
