Title: Water booster pump unit for high rise buildings - has time delay control making pressure differential negligible, thus preventing frequent stop/start
Inventor: LUTTERLOH HARALD
IPC: F04B49/10
Filed: 1973-07-17
Abstract: The pump is started when the pressure in the delivery line drops below a set value. When the pressure has reached a higher set value, a timing device is started which stops the pump after a given delay. If during this period the pressure drops again to a slightly over value the timing sequence is stopped, the control reset to zero and the pump allowed to continue. In this way frequent stopping and starting of the pump is avoided and the delivery line can be kept at almost constant pressure.
