I assume this is a centrif pump, API 610? You should specify the worst’s case condition, i.e. highest head and flow, once you receive the pump curves from the pump supplier you should check that any other operating conditions the pump may need to work in fall within the limits of the curve, i.e...
Sorry 'JPiii' but i must be reading your posts wrong? You last post stated "If pressure is held, Air Valves #1 and 2 are opened and full transfer occurs". So does this mean you are hydrotesting the line with the process fluid, in this case an acid! The point of doing a hydrotest is to check the...
hi TD2K,
Yeah, thought about that already, but typically canned pumps are for quite high flow rates (or high compared to this duty!). I think I’m going to have to go back to our process department and find out if the pressure in the vessel can be increased as there doesn’t seem to be anything...
Thanks for the responses, i have emailed both suppliers and waiting on a response. I’m not holding out much hope, based on the info on the websites my duty flow rate is too low. Also the pump will be located in a Zone 1 hazardous area, again based on the websites neither of these supplier have...
I'm trying to find a pump suitable for the below application but having no joy, pump will be offshore and unfortunately it’s on the lowest level of the platform so no chance to increase the NPSHa. Unfortunately we cannot increase the low low level in the vessel so the static head is fixed. Pump...
