Hi / Lo System – High Pressure Operation
When the work load is linked and work pressure is wanted, pump – electric motor pressure starts rising toward the relief valve setting of 1500 PSI. When it passes thru the 500 PSI pressure level, the normally closed unloading valve opens letting the 45 GPM pump to unload while the 5 GPM pump tries to work. This is taking place to eliminate unnecessary power generation by the 45 GPM pump when it is not needed.
