Understanding Gear Pumps - Part 3 (Final)

This is the final article in our 3-part Gear Pump Series where we address some inaccuracies in a competitor publication. Most of our responses in this section echo what we’ve already stated in our previous two articles on gear pumps. Despite the repetitive nature of this, we will go ahead and address each topic as we have done in the previous responses.


We hope that this helped to clear up any misconceptions about gear pumps. Our mission has always been to advance the spray foam industry through innovation, technology and transparency. Our gear pumps are designed using only the best quality materials and engineering that is specific to the fluid dynamics of the chemicals used in the industry. We use gear pumps because they meet the high performance standards that are an integral part of the technology used to drive our system. If you prefer a piston pump system, then by all means, use piston pumps. We are not here to detract from that. However, we do want you know that you have other options. We want to provide you with the facts so that you can make your own informed decision on what’s best for you and your business.

Gear Pumps

As in our previous response, gear pumps hold stall pressure if the system is designed with a check valve (input and output side), therefore making this a non-issue for comparison purposes.


Piston Pumps

As we have answered previously, piston pumps as well as gear pumps hold stall pressure. It’s a matter of designing the system to do so.

Gear Pumps

  • Gear pumps, as well as piston pumps will wear over time. See page 4 of Graco’s Ratio Assurance White Paper. “The equipment is also mechanical and will require preventative maintenance over time and experience issues that require repair.”

  • Our gear pumps are designed to take fluid shear into account and are designed specifically for the fluids of this industry.

  • As in our previous response – our flow meters should be recalibrated once every 7 – 10 years per our calculations and manufacturers specification.

Piston Pumps


Again, mechanical equipment will require preventative maintenance and experience issues that require repair. (Page 4 of Graco’s Ratio Assurance White Paper)

Gear Pumps

  • Akurate offers a guarantee on our gear pumps. If maintenance is required, customers can exchange their gear pumps to avoid future downtime.

  • Gear pumps can wear. As in our previous response, our gear pumps are not “off the shelf” and are designed from the best materials and are specific to the fluids used in this industry.

  • If maintenance is required, our technical support team will ensure that the total system is operating properly.

Piston Pumps


Both piston pumps and gear pumps are mechanical equipment that will require service and maintenance. These piston pumps are designed in such a way so that the expected rebuilds can be done in a shorter time frame.
