Purpose:
The purpose of this lab was to gain a basic amount of understanding of the design, funciton,
and characteristics of fluid power and fluid transfer pumps. This lab was focused on two types of
pumps: positive displacement and non-positive displacement. It will provide the understanding
of the fundamentals of these pumps as well as teach how to calculate the flow rate of a pump.
Procedure:
We first began by discussing the functions of positive and non-positive displacement pumps and
what the differences between them were. Then, using calipers, we took measurements of
different areas of the pumps. These measurements will later be used to calculate both GPM and
CIR of these gear, vane, and piston pumps.
Results:
Gear Pumps and Motors: GPM (1800 RPM) = 17.00 GPM CPI = 2.170 in 3
Vane Pumps and Motors: GPM (1800 RPM) = 26.52 GPM CPI = 3.386 in 3
Piston Pumps and Motors: GPM (1800 RPM) = 60.62 GPM CPI = 7.779 in 3
Conclusions/Recommendations:
When comparing these three types of positive displacement pumps, you will notice that the
