Thanks I have just cracked the puzzle as to why it wasn’t priming. Pump is self priming as we speak and I have programmed it to start/stop based on Level.

Start/stop is local. There is a low level cut off for motor. And it has to be manually primed for each start when it gets to a certain level. There is no remote start/stop at the moment

Seen ?

The pump is there. The waste water goes into the sump and when it gets to a certain level. Pump is turned on and when level gets to a certain low level . Pump shuts down. There is also a feed line for prime water into pump casing

This is how the flow goes. How do you implement your deliberate priming of pump based on your suggestion?

So the pump motor is already wired to DCS and there is a Radar Level transmitter to monitor Sump Level. I think I can just program the start and stop of Motor directly in the DCS instead of going through a longer route. Once I can have the pump primed automatically whenever the motor stops based...

good idea. i incline to prime before each start wether it is needed or not and also have a foot valve

oh well its a newly installed pump

thanks. yes i would have installed a different pump if i had nmy way. only trying to salvage the situation.Thanks

Yes it is self-primer pump that requires manually filling the pump case with prime water so that it will pick up prime and start pumping and not damage the mechanical seal. What would be the best way to solve this issue of priming since I want to automate pump based on the Level of sump. Adding...

yes i really like those vertical mount float switches for level control but dealing with pump prime and shut down protection is another thing.lookimng for something not too complicated but very effective

yes good idea but what would be the best way to handle the pump prime. i am looking for a way to handle the prime remotely as well as automate the pump start stop based on sump level

Thanks but due to the concern of the pump prime, what would be the best way to effectively prime pump or hold prime before automating the pump. even if the pump is automated and there is no prime . This will lead to pump damage.what do you think?

I have a self primer pump that requires to manually fill up the primer case with prime water to enable it pick up prime and start pumping and avoid damaging the mechanical seal.The pump is used for a sump that i need to automate based on the sump level.i plan to add a foot valve. do you think...

This is within a plant environment for Tank Car loading rack grounding. Ie the Portion normally occupied by cars to be insulated from main tracks. And all rails in the insulated section to be bonded together. This is per bonded to loading arms and loading rack structure and grounded or...

What are the relevant standards for grounding and bonding of Rail Road tracks ?I know Article 250 per NFPA talks about grounding and bonding but i am looking for very specific information on the applicable standards in this case?

I have an existing Radar Level transmitter on a Tank with a HART protocol. I want to hook up a pressure transmitter to same tank but on the already existing loop. what is the best way to run thisn connection as i think thisnis possible since they have same HART protocol.I need very clear ways...

What other ways can you think of?
