There is more that goes into buying a pump for your sprayer than you may think. Whether it's a centrifugal, diaphragm, roller, or piston pump, the right type of pump for you is definitely out there. It's easy to get overwhelmed by the many options available today but selecting the best pump doesn't have to be hard or time-consuming.
Our Customer Service Technicians handle many calls dealing with this very topic, so we asked them "What should customers consider when purchasing a pump?" and here's what they told us:
Flow Rate: This is measured in gallons per minute (gpm) and you'll want to determine your required flow rate before you shop. All pumps have a maximum gpm flow rate so you'll want to ensure the one you choose meets that number. A good tip to remember is: a higher flow rate means a larger pump size is needed.
Fluid Type: Are you spraying a clean fluid or an abrasive chemical? Is it low or high viscosity? These are just some of the aspects you'll need to consider when choosing a pump. The type of fluid being sprayed matters as there are specific pumps that will work best for your application, and some that just wont do the job.
Flow Pressure: Use this simple formula to calculate your required pressure:
Desired Pressure at Nozzle (psi)
+ Hose Pressure Loss (psi)
Total Pump Pressure Needed (psi)
Once you've determined your requirements, you will have a better understanding about the type of pump you need. However, the search doesn't end there! Our Customer Service Technicians also recommend you ask these 8 questions before you purchase a pump:
