Frequently Asked Questions

 

Since 1953: Not Just Pumps, Pumping Solutions
There are many variables that must be considered when specifying a magnetic drive pump for an OEM application. At first glance you may not find a pump that meets your exact requirements. GRI recommends that you contact our Technical Sales Staff to discuss your project so that the right pump can be specified. Many times we will customize an existing pump to meet your needs or design a new pump according to your system’s exact specifications.

 

The Importance of Specifying a Pump Early in the OEM Design Process
Check out GRI’s “Emphasis On Pumps” article in the October 2013 issue of MDT magazine.  Knowing the specific fluid pumping requirements of an application upfront in the development process is important. Unfortunately many device and system designers neglect to consider the fluid pumping requirements until late in the design process.

 

Many times a designer will have to perform costly alterations to systems or devices to make their design compatible with a pump chosen late in the design process. Being that many times a pump is the “heart” of a system, it makes sense to begin the specification process early rather than later. Careful planning saves not only time and money, but also headaches.
