Hello everyone,
We need to specify some pump type for skimmed/recovered oil transportation. It seems both gear pump and air diaphragm pump applicable for this service. Could you please advise which one is better and why it's that? Your help would be appreciated.
Thx first.

API 675 states that direct mechanical diaphragm pump is out of the scope. does that refer to the air controlled diaphragm pump? if air diaphragm can't refer to API 675, does that mean only manufacturer's standard applicable? Thanks for your information.
Hi guys, first thank all of you for your replies.
I need to prepare a data sheet for pump purchasing. For hydrolic and performance test, for sure we need them. But I'm not sure if the 4-hour mechanical run test is needed or not. On API 610, Clause 7.3.4.7, only says: when specified, Mechanical...
Hi everybody,
How are you?
Could you please give me some hint on when to request a mechanical run test for API 610 pump? is it related to pump hp or head or flow rates? Thank you.
All the best,
Hi everybody,
How are you?
I have to decide if mechnical run test is needed for some small API pumps. Could you please give me any hints on it? Thank you.

Try the Moyno vertical pump. It specially works well with viscous fluid. Here is the link for your information.

Reducing the sand to the pump using perhaps a basket strainer or y-strainer might help if it does not reduce the pressure drop to the pump that may Affect the NPSHA..
Beyond that, you might consider another type of pump such as a slurry pump?
I prepared a RFQ package for CSA Z245.1 Gr. 359 Cat.I pipe, 24", 600# . Why did most vendor quote back as API 5L X52 or X60? How to evaluate the difference? I didn't find the answer from the two Standards. Can anybody provide help to make it straight for me? Thanks in advance.
MJC,
If my friend provides the explanation, you can help to solve the problem, is that right? In this case, I would like him to reply to you.
Thanks in advance.
One friend is currently working on a small design problem and need some mechanical analysis done, if any of you could give him a hand it would be much appreciated

I googled two websites for conversion of gauge to micron, but one shows that 1 gauge =o.254 microns, while the other shows that 1 gauge=25.4 microns, with 1000 times difference. The two websites are listed below:
