We have 3 pumps for hot water circulation at a copper smelter. For seal flushing, we have a heat exchanger.The common thing on all these pumps (new or refurbished ) is that when the pump is placed on standby, the mechanical seal starts to leak a few weeks into being installed. The leaks then affects the seal temperature, rising as high as 99 degrees in some cases. To protect the seal, we have 90 degrees as the alarm temperature and 100 degrees and the trip temperature. However, when the pump is in service (running/on duty), the seal temperate is usually between 35 to 50 degrees and the seal does not leak, usually just a drop every now and then. Why and how does this happen?

Concept is absolutely clear with pipe hose example that less flow more head, But as per fundamental theory, Once you put finger your on hose then less area, LESS PRESSURE Which means low flow Law pressure, THIS IS JUST CONFUSION

Could pressure gauges be installed in the mechanical sea itself in order to monitor the seal chamber pressure?
@hamzadriss1358 Жыл бұрын
yes, you can use existing F connection of the pump or the F or PI connection from seal gland if it has been already advised to vendor.

I guess if you assume the pump is in perfect shape this is a good guide

In Plan 13, how can you make the seal chamber pressure higher the suction pressure for vertical pump?
@nnn7369 Жыл бұрын
Just my opinion, the pump discharge pressure is the same as the back casing where seal installed, because impeller accelerates fluid, you may look up how centrifugal pump works video made by engineering mindset!

What about the API Plan 65 is it possible to use with the LPG pumps as a single arrangement ?
@hamzadriss1358 Жыл бұрын
LPGs have higher vapor pressure meaning that your leakage will be gas and not liquid and gas tend to rise, therfore, the use of a plan 65 or B IS NOT recommended and useful.

Does it seem reasonable to develop a system curve for a process in a plant so you can choose the correct pumps and or verify the appropriate pumps are installed?

It is normal for the seals to leak, this is what they are design for. As long as there is no leak to the atmosphere, then it is normal.

Thank you so much very good presentation, in our plant we use plan 53-B so what is the difference between 53A and 53B ?
@satheeshkumar-mg6ru 6 жыл бұрын
53A we will have seal pot only along external pressure, but in 53B you have heat exchanger along with seal pot,the pressure of buffer fluid maintained by Accumulator..
@tawadhu1104 4 жыл бұрын
@@satheeshkumar-mg6ru is the 53B more fragile to dirty fluid such as solid or sand compared to 53A? The pump installed in our facility has 53B seal type and the 1/2 inch flushing line between stuffing box and discharge head is frequently got burst eroded by the sand. I wonder if it can be solved by modify the sealing into 53A and permanently plug the flushing line.
@ghosalarghya 4 жыл бұрын
53B will have bladder accumulator which 53A doesn't have. Accordingly in 53A nitrogen mixes with the fluid. But in 53B it is not the case.
@Varunkm110 4 жыл бұрын
The main difference between plan 53A and plan 53B both are pressured barier plan 53B can handle more pressure than Plan 53A . In plan 53 A manually feed nitrogen .where as in plan 53B acuumaltor and bladder make up line separately . Almost plan 53B works has stand alone unit . If plan 53B fails check the pressure of your process line . Consultant application engineer or system design engineer before changing any thing.

Can you please explain, @16:05 , why should one go for high powered pump, when one can get the same flow rate to the same head with a larger window of operation on a low powered pump. Why are different pumps having the same pump curve?
@mohamedrefaat8669 6 жыл бұрын
It's only illustration image, each pump should have its own curve not the same curve, higher horsepower's curve should be above medium horsepower's curve and low horsepower's.

Great presentation. On the plan 62, is the flush port always plugged? It appears that way on the graphic. Thanks!
@SiewertEquipment 6 жыл бұрын
Hello Jay and thank you for watching. The Plan 62 is a Steam Quench on the atmospheric side of the seal. It’s used to remove solids build up like coking, or salting. The inlet should be on the top and the drain at the bottom, and YES the drain should always be left open. You can, and most people do, install a steam trap but make sure the maintenance is done on the tramp. If it plugs, the 62 will not work properly and you will fail the seal.
@itsjustJay863 6 жыл бұрын
Thanks but I was referring to the flush port. Looks plugged on the picture (in red)
@SiewertEquipment 6 жыл бұрын
Oh I see what you’re asking, the short answer is No that port is not always plugged. That port is on the process side of the seal and can be lined up with any single seal flush plan that the seal requires, like 11 or 13. Typically you will see this called out on a spec sheet or described as: “Seal Flush Plan 11/62”.
