Q: What is the function of the pump?

A pump produces liquid movement or flow: it does not generate pressure. It produces the flow necessary for the development of pressure which is a function of resistance to fluid flow in the system.

Q: Name different types centrifugal pumps?

Multistage pumps, Process type pumps, Chemical process pumps, canned motor pumps, Paper stroke pumps and deep well turbine pumps.

Q: Name different types of rotary pumps?

External gear pumps, Internal gear pumps, sanitary type pumps, External screw pumps, three screw pumps, Swinging and sliding vane pumps and Flexible rotor pumps.

Q: Name different types of reciprocating pumps?

Steam pumps, Power pumps, Metering pumps, Axial piston pumps and Sucker rod pumps.

Q: Explain what is positive and non-positive displacement?

Positive displacement pump are those which discharge specific amount & quantity is constant. Â non positive pumps are those which discharge random amount & quantity varies. Positive displacement pumps are that which prevents undesirable flow and pumps the fluid within the closed space.
Ex: Reciprocating pumps Rotary pumps. Its efficiency is more when compared to non-positive displacement pumps.

Non-positive displacement pumps have no provisional to prevent the reversal of flow. We can say that there may be some loses in this kind of pumps but the main advantage is it can be used when high pressure and large quantity of fluid is to be pumped.

Q: What is Auto Dosing?

Auto dosing is an automated system of feeding the equipment with liquid products. It is the ideal way to ensure the correct calibrated dose at the right time every time in auto
