Submersible Pump
Do not use closed-center valves. Return
flow from the hydraulic motor must be
allowed to return directly to the oil res-
ervoir to enable the pump impeller to
gradually slow to a stop. Closed-center
valves will block this flow, causing dam-
age to the hydraulic motor and/or the
pump seal.
