Pump
What is a pump?
A PUMP is a device that moves fluids (liquids or gases) by mechanical action. When a pump contains two or more pump mechanisms with fluid being directed to flow through them in series, it is called a multi-stage pump. Terms such as two-stage or double-stage may be used to describe the number of stages specifically. In contrast, a pump that does not fit this description is simply a single-stage pump .
Types of Polymers used in DYNAMIC Pumps that impart velocity and pressure to move fluid:
- PTFE & Filled Grades of PTFE
- PEEK
- Carbon fiber filled PEEK
- Polyimide
- PAI
Types of Polymers used in POSITIVE DISPLACEMENT Pumps which lift a volume of fluid per cycle:
- PTFE & Filled Grades of PTFE
- UHMW PE
- PPS
- PEEK
- Carbon fiber PEEK
- PI & PAI
Two Pump Types: Dynamic and Positive Displacement
