Pump High Discharge Flow alarm

[SZL]

Gent,

last month, we installed two pumps on the outlet of the pressure sewer drum. The function of pumps to pump the hydrocarbon that entrained from our feed gas to treatment plants where gas, oil and water are separated from each other. If the level of the drum reaches certain point, the pump will start and one pump is the back up of the other. Nowadays, we have problem with high flow alarm on pump discharge always activated on the control room. Please I would like to have your recommendation what is the optimum solution to resolve this alarm.

Easiest thing to do is turn the alarm off, but that's probably not the optimum solution.

I don't have any details of your system, so here's a few questions:
Do both pumps cause the alarm?
Does the alarm go off when the pumps are stopped?
What activates the high flow alarm - if it's a switch, is it stuck?
Are you measuring flow? If not can you correlate pump motor amps back to a point on the pump curve to see where they are really operating?
What is the problem with high flow? Is it to do with the pumps, or is it process related, i.e. can the alarm setpoint be set higher?

There's some initial thoughts anyway,
Cheers,
John
