The pump trimming happened at the distributor which I was not apart of. The impeller can be removed without touching the mechanical face seal. The stationary element did not appear damaged for the one pump that was rebuilt.
The suction side hose will be replaced with all rigid pipe and a...
Hi Tug,
Originally it was Buna-N/ Nitrile, the new failed Viton unit is still in service. Spoke the the distributor earlier and he clearly confirmed these units fine for oil service....
Perhaps pushing more flow will better cool the rubber seal elements.
Hi Shaggy,
A positive displacement gear pump is what came out. Those had their own issues. With the trimmed impeller the flow rate can be lowered. The stock charts are for the 4 inch impeller.
You are correct that this pump is listed for water service only.
Hello,
Very stuck with this issue and curious what to do. It has to be something simple.
I've used these pumps (Ingersoll Rand Flowserve SMP-1000 centrifugal) before, 4 times, in a similar application with great success. Now I've installed 5 units where the seal begins to leak within 5...
Hey ElectricPete,
I thought exactly as you'v noted it that there would be some back story on this. It's odd that ANSI B17.1 doesn't give the key class for motor shafts either.
Hey,
Just curious if anyone had run across Table 6 in B17.1 says the width tolerance of square keyways/keyseat for 0.25-0.75" wide was +0 -.002/ 0.75-1.25" wide was +0 -.003". Therefor the keys would be shrunk. There is no direction as to what class of Key is required,Class 1 or 2 on a motor...

Hello,
I've been looking for a replacement gearbox unit for 12+ months with no luck. Cannot believe this style of gearbox isn't sitting on the shelf somewhere.
The output shaft have to be 90 degrees apart. 480 ft-lb / 651 Nm torque capacity required 80-130 rpm operation
Our old gearbox is...
Bimr,
Were you on this project? The spec did have a #200 mesh/75 micron auto screen strainer and a manual screen strainer of identical construction to the Lakos filter. That auto strainer failed in multiple ways. Differential pressure strainers trying to vacuum or spray the debris of the...
LittleInch,
We are trying to remove solids 75 micron and larger from a water source @150-200 gpm max per strainer.
Eaton were the first individuals contacted. I've purchased a handful of their DCF-1600 series strainers over the years with excellent results. Unfortunately the outside scrapper...
Hi,
Some of the parameters were in the subject but here they are
200 Gall/min @ 75 Micron
Input pressure 30-50 psi.
Differential Pressure 3 PSID Clean max -6 PSID dirty pre deluge cycle.
Thanks,
Hi All,
I've got a fairly unique issue with respect to process water taken directly from a river close to a Glacier and being filtered down to 75 micron.
The water is fairly silty with glacial till, talcum powder like fines. Algae is also present in the water stream. The fine size particles...
