By the end of this assignment, students will be able to do the following:
Identify the (3) major pump types used in fluid power systems.
Distinguish between fixed and variable displacement designs of the above pump types.
Describe the operation of the above various pump types using visualization techniques.
Understand that every pump design has limitations and is not 100% efficient.
Explore trade-offs between pump types.
Instructions:
Draw and label each part of the following types of pumps and explain how they function to produce hydraulic fluid flow:
1. Gear Pump (fixed)
2. Vane Pump (fixed)
3. Vane Pump (variable)
4. Piston Pump (fixed)
5. Piston Pump (variable)
For starters, read the assigned text and watch the following video that shows animations of hydraulic pumps and use it to inform your design practice.

Understanding how these pumps work will assist you with more detailed calculations that we will discuss in later units especially as it concerns volumetric displacement and the amount of flow a pump can produce. Note that this is not the only “how do hydraulic pumps work?” resource available. share other helpful resources on your reference page.
