Chemical process pump are of different types, including centrifugal, self-priming and vertical sump. Centrifugal pumps operate by means of using centrifugal force to create differential pressure for pumping. Self-priming pumps can be applied to pump gases and liquids in chemical processing industries where non-self priming pumps cannot work. Vertical sump pumps are used in submerged conditions and can be applied in industries where corrosive liquids are found. They can also be used in oil and petroleum industries as well as normal chemical processing industries. Send your Chemical Process Pumps requirements at Email: sales@ppipumps.com PPI Pumps Pvt.
