What is GPM from CC/REV and Why Should You Care?

Ever found yourself scratching your head over hydraulic pump efficiency or flow rate? Enter the concept of "GPM from CC/REV." Simply put, this handy calculator helps you figure out how many gallons per minute (GPM) your hydraulic pump is dishing out based on its cubic centimeters per revolution (cc/rev) and its rotational speed (RPM).

Why should you care? Understanding this can save you from all sorts of engineering mishaps, improve your system's efficiency, and even save you some hard-earned cash. After all, why guess when you can know?

How to Calculate GPM from CC/REV

Ready to dive in? Calculating GPM from CC/REV is simpler than it sounds.

Step 1: Determine the total cc/rev. This is the volume of fluid your pump moves per revolution.

Step 2: Determine the total rotational speed in RPM. This is how fast your pump is spinning.

Step 3: Use the formula:

For imperial units:

[\text{GPM} = \frac{\text{CC/REV}}{3785} \times \text{RPM}]

For metric units:

[\text{LPM} = \frac{\text{CC/REV}}{1000} \times \text{RPM}]

Where:

  • GPM (Gallons per Minute) is the flow rate you're trying to find
  • CC/REV is the total cubic centimeters per revolution
  • RPM is the total rotational speed in revolutions per minute

Step 4: Plug in your numbers and calculate.

Calculation Example

Let's make this super clear with an example.

Example Variables:

  • Total cc/rev = 7
  • Total RPM = 1200

Using the imperial unit formula:

[\text{GPM} = \frac{7}{3785} \times 1200]

So:

[\text{GPM} = \frac{7}{3785} \times 1200 \approx 2.22]

That means, with these values, your hydraulic pump is moving approximately 2.22 gallons per minute.

Knowing how to calculate GPM from CC/REV gives you a clear picture of your hydraulic system's performance. It's an essential tool in your engineering toolkit, ensuring things run smoothly and efficiently.

Frequently Asked Questions

GPM from CC/REV helps you determine the flow rate of hydraulic pumps, which is essential for understanding system efficiency, sizing components, and troubleshooting hydraulic systems.

For metric units (LPM), use the formula: LPM = (CC/REV / 1000) x RPM. This gives you the flow rate in liters per minute instead of gallons per minute.

The number 3785 represents the conversion factor from cubic centimeters to gallons (1 US gallon = 3785.41 cubic centimeters).

Actual flow rate can be affected by pump efficiency, fluid viscosity, temperature, system pressure, and mechanical wear on pump components.
