Different Types of Pumps & Their Working Methodology ...

Working Of Screw Pump. Screw pumps also falls in the category of rotary pumps and have the same mechanism and principle. Screw pumps are the only type of pumps which are different from other rotary displacement pumps because of the axial flow of the fluid through their pumping elements.The fluid in screw pumps moves between the screw threads and is displaced axially as the screws rotate and mesh.

Rotary evaporator - Wikipedia

A rotary evaporator (or rotavap /rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was ...

Rotary Airlock Valve Principles and Rotor Design | Powder ...

Apr 03, 2018· Rotary airlock valves are a critical component in many material handling systems. From dust collectors to pneumatic conveying systems, rotary airlocks not only control the feed rate but also minimize air leakage between equipment above and below the valve with differing levels of pressure or vacuum. In dust collection systems the rotary airlock allows continuous product discharge without ...
