1"inch PVDF (Kynar) Air Operated Diaphragm Pump for Nitric Acid Chemical Insutry

INTRODUCTION

A air operated diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber or PTFE diaphragm and suitable valves on either side of the diaphragm (check valve, flap valves, or any other form of shut-off valves) to pump a fluid.

There are three main types of diaphragm pumps:

• Those in which the diaphragm is sealed with one side in the fluid to be pumped, and the other in air or hydraulic fluid. The diaphragm is flexed, causing the volume of the pump chamber to increase and decrease. A pair of non-return check valves prevent reverse flow of the fluid.
• Those employing volumetric positive displacement where the prime mover of the diaphragm is electro-mechanical, working through a crank or geared motor drive, or purely mechanical, such as with a lever or handle. This method flexes the diaphragm through simple mechanical action, and one side of the diaphragm is open to air.
• Those employing one or more unsealed diaphragms with the fluid to be pumped on both sides. The diaphragm(s) again are flexed, causing the volume to change.
