PTFE (virgin polytetrafluorethylene) is a thermoplastic polymer with superior chemical resistance. ... The PTFE pump will handle even the most aggressive acids, for instance concentrated nitric acid. Maximum liquid temperature is up to 100°C.
What is PTFE diaphragm?
Polytetrafluoroethylene (PTFE) diaphragms Also known as Teflon, PTFE is used with highly aggressive fluids such as aromatic or chlorinated hydrocarbons, acids, caustics, ketones and acetates. Its properties provide excellent flex life and moderate abrasion resistance.Jan 6, 2015
Is tefzel the same as Teflon?
ETFE, or ethylene tetrafluoroethylene, consists of carbon, fluorine and hydrogen, has a higher tensile strength than PTFE, though PTFE will stretch before breaking. It is also more heat resistant, melting at 327°C, which is 60°C more than ETFE. ... It's commonly known as Teflon®, a non-stick coating.Mar 1, 2014
Are diaphragm pumps positive displacement?
The Working Principle Of A Diaphragm Pump A double diaphragm is a positive displacement pump which utilises two flexible diaphragms that reciprocate back and forth, creating a temporary chamber, which both draws in and expels fluid through the pump.
What type of pump is a diaphragm?
positive displacement pump
Which type of pump is positive displacement pump?
Positive displacement pump or PDP is a type of pump in which a certain amount of fluid is captured inside the cavity, and then discharge the same. This displacement of fluid takes is done by plunger, piston, diaphragm etc. depending on the type of the pump.Jan 5, 2018
