Lime Transfer Pump Underachieving
Lime Transfer Pump Underachieving
(OP)
Hi Folks
I have a lime transfer pump installed at a municipal site and it should be achieving 8 LPS @ 4 mtrs head, it is a 1.1kw 2900 rpm motor, the pump is only achieving 1 LPS and to be honest its got me pretty confused. https://res.cloudinary.com/engineering-com/image/upload/v1456957128/tips/S28C-6e16030308130_gzrxmr.pdf

the installation.

Need to know much more about set up and operating pressures / head

Given that you are pumping lime i assume you are actually pumping a lime "slurry" or a fairly concentrated solution.
These type of installations are notorious for three things.
1) Blocking and clogging of the pipework. This will increase the head dramatically on the pump which ultimately causes reduced flow.
2) The intake becoming clogged or blocked by precipitation of the lime slurry in the supply tank due to poor mixing.
3) Dry running caused by one or both of the above damaging the pump.

It's got the rest of us a bit cheesed off that the OP hasn't bothered responding to any of the posts..... hasn't looked since 6th March and isn't notified of any posts - waste of time doing anything more here I think.
