Happenings:
We have hit the final stretch of the year, and we didn’t think it would come up that fast.
After an amazing summer GPM has been at it again! We went to MinExpo and showcased the PEMO pump line for the Mining and Aggregate Industry. This show went off well and allowed us to introduce ourselves to a number of new potential clients as well as new OEMs.
The ASPE show was held in October in Columbus, Ohio. This plumbing show allowed us to talk and work with several of our partners in the commercial market.
We want to thank all of you who showed up at one of the shows, it means a lot not just to us, but also to the OEM representatives that were at the events.
We will have a booth at AHR in Orlando in February and are planning for the AGG1 show in March as well, but more about that in the Winter Newsletter.
Best Regards,
Greg, Dan, Tom, Debbie, Scott, Tristan, Samantha, Drew, Joey, Dee, David, Chris, and Paul: “The GPM Team”
DP Pump Updates
DP Pumps is getting a new seal. Eagle- Burgmann has updated the seal design to their eMG design version (old style on the left new on the right).
This new seal is a direct replacement for the existing unit and requires no modification to the pumps for installation. We have already begun using these, and sending them out. The only real noticeable difference is the size of the sealing face on the fixed side of the seal.
We also know that we have had issues with the DP select software. DP recently informed us that there are two new changes coming. The first is that they are working on the update to fix the lack of the DPVF with SAE/ANSI information in DP Select, and this should be out before the end of the year. The second is they are working on a new software program with multiple improvements to make pump selections easier.
Victor Pump News
Victor Pumps is now offering a new alternative to the standard steam-jacketed pump. The new option is using an electric heat system that can be easily connected to the electrical panel to keep the pump (and the liquid inside) warm. This is great for areas where a heating fluid is not available, or when a mobile application is needed. Let us know if you need more information on this new option.
Upcoming Events
Join us for our upcoming events that we will be participating in. Here are the details:

There have been a few questions about how we calculate the NPSHa (Net Positive Suction Pressure Available) for a pump system. And when dealing with a system that is open to atmosphere it is a matter of plugging info into a simple formula:
NPSHa=absolute pressure on surface of liquid (feet of liquid) – vapor pressure (feet of liquid) + static height of fluid – friction losses (feet of liquid)
Vapor Pressure: this is the pressure at which a liquid will turn into a vapor (steam).
Static height: this is the static height of the liquid above the centerline of the pump suction in feet
Friction Losses: this is the loss in the pipe and fittings coming into the tank and this also has a minor relation to the necessary flow rate of the pump as well.
So, if a pump is being fed from a tank and the low water level is 6’ above the centerline of the pump and the water temp is at 180F the formula would look like this:
NPSHa=(14.7 psi*2.31 ft/psi)-(7.5 psi
*2.31 ft/psi)+6-2 NPSHa=33.96-17.325+6-2 NPSHa=20.635’
Please note this is a very basic example and if you need more help please reach out and we will happily offer more training, show you how we found the numbers, etc.
The Greenpumps GPCA magnetic drive centrifugal pump can be configured in centerline mount to meet API 685 which is the magnetic drive equivalent of API 610. The centerline support allows thermal expansion growth of the casing to be symmetric from the shaft centerline outwards. This allows coupling alignment to be maintained regardless of temperature variations. The GPCA is capable of temperatures from -150F to 660F (750F w/ external cooling) and total working pressures up to 1500PSI.
These capabilities along with the absence of a need for a mechanical seal make this pump suitable for oil refinery/petrochemical, thermal oil, powerplant, boiler and chemical transfer applications. GPM is currently working on an application pumping Naphtha with a total working pressure of over 1200PSI with Super Duplex SS casing and Titanium Grade 5 containment shell.
