As a millwright, these designs are the holy grail of ease and success. The few engineers we long for

There is a lot of difference between changing the seal in a new pump and the one which is currently in use. When scale gets deposited in the neck ring at the bottom, the impeller gets stuck in it and neither gets lifted up easily nor gets pressed down. If it does not get pressed down, the nut at the top does not come out and there is not enough space at the top for it to come out. The second fault is that the mechanical seal at the bottom also works as a support for the shaft bush. If the neck ring gets cut, then vibration occurs which breaks the seal which is very hard. I have faced this problem myself.

Wow I cannot believe how easy it was to remove the seal!!! Oh, well what about when it’s been on for several years. You should do a video of how it really is , not one showing the removal of a brand new seal!!

thanks mr murphy to show this video i am presently working with empower energy solution uae we used nearly 150 nos of armstrong make vertical in line pumps.as a technician i am still unabel to understand how the mounting of these pumps are working .we use some pipe hanger n vibrator arrestor but still some vibation occurs during opreation .why?also why no thurst bearing designed in motor even axial load of imppeler is on bearings

How come the suction and discharge isolation valves are the same exact valve?

Rebuild /seal kit part number would be helpful, so I can order the assembly you put in

Armstrong worst pumps in the industry!! Always easy to work on a pump with no corrosion or wear on it. All clean and nice , not the real world.

I have my crew working on our first Armstrong pump today. It's one of the Dual Pump/Pumps. Were able to chang out one seal successfully. The second one is a pain in the butt. They had a good idea, but not after a pump has been in service for many many years. Corrosion makes it almost impossible to get it perfect.

cleaning the pump shaft with emery cloth so the crap can fall onto the stationary face, never in a million years. bloody awful pumps

clean it before you put the new stationary face on it.
