Greetings
I have a closed drain system composed of
drum and two submersible centrifugal pumps, l asked the contractor to add minimum flow line for the pumps , but they refused. They said that since pumps start when liquid level in drain drum is high and stop when they liquid level is low, there is no need for the minimum flow line, in addition that the pumps work intermittently not continuously.
I think we need to minimum flow line even with these justifications.
