Broyce Control offers Pump Control relays that are typically used to balance the wear between pumps and hence extend their life by alternating between them.

Liquid Level relays are used to monitor and detect the presence (or lack of) liquids such as water, waste water, tap water etc and operate accordingly. This could be ensuring that a pump is instructed to run and begin filling a tank if the liquid level drops to a certain point. Alternatively, it could be telling the pump to stop if the liquid level rises too much.
