Hydraulic Power Units

The function of these power units is quite simple. When enough oil has been used out of the oil storage system to drop the pressure to the cut-in switch setting, this switch restarts the pump motor and pump will run until oil storage system is refilled sufficiently to bring pressure up to cut-out switch setting, which stops pump motor. The operating cycle is exactly like that of an automatic home water system.
