What Are Positive Displacement Liquid Pumps?
Positive displacement liquid pumps are pumps that move a constant volume of fluid with each cycle of the pumping mechanism. They create a vacuum and force the fluid to move by trapping a certain amount and pushing it through the discharge valve.
About Single Diaphragm Liquid Pumps
A diaphragm pump is a type of positive displacement pump that utilizes a flexible membrane or diaphragm as its main pumping element to move and pressurize a fluid. A single diaphragm liquid pump, more specifically, discharges fluid while moving in only a single direction.
A diaphragm pump is very versatile, and offers various benefits, such as:
- Lightweight and portable construction
- Suitability for operation in corrosive environments or for pumping corrosive fluids
- Composed of few parts and requires little maintenance
- Features self-priming properties
