    plan 53 flange system question

    Got a question. I have seen pump vendors having a flanged (welded) plan 53 system and tubing running from the flange to and from the the seal. Is this common? Why would they do tubing rather than piping? If system is not to see the process media, why not NPT rather than flanged? I dont see...

    NPSHa vs NPSHr

    Hello: I have an application where the vapour pressure (in gauge) is slightly higher than the pump suction pressure. This information was retrieved from the pump datasheet. However there is a postive difference between the NPSHa and NPSHr. How does this work? Shouldn't the pump be...

    Differential Pressure

    I received a datasheet with suction pressure the same as minimum, rated, and maximum. However the discharge pressure is different for all the min/rated/max pressure. For the same fluid and shaft speed, can the differential pressure be different?

    Steam out conditions

    What effect does steam out condition have on the seal? The customer has told us the pump will be subjected to the steam out condition at 24psi@267F. From the seal point of view, what questions should be asked to the customer, if any?

    Process Fluid Leakage

    In general, what could be the potential causes for the process fluid contaminating the barrier fluid regardless of how high the barrier pressure differential. The seal chamber pressure is monitored and does not vary much, the barrier pressure is always maintained higher, but when the barrier...

    Shrink fit vs sold piece components

    All: Which is better,having seal face inserts shrink fitted in seal face holders or having one solid piece of C/SiC? I have seen both from different seal vendors, just wanted to know pros and cons of each and which is better.

    Heat Transfer Rate formula

    Hi All, The heat transfer rate formula is Q (BTU/h) = 500 * Cp * SG * Delta T......what is the 500 represent? What if the rate of heat transfer was Watts? How would the formula change? Thanks for your help!

    Heat Transfer rate in HE

    I have some general questions regarding heat transfer rate. Assuming we have a shell and tube heat exchanger, with the hot fluid going through the coils and cooling water through the shell. As per my limited understanding, if we have turbulent flow of hot fluid going through the coils, this...
