The P-AAA Series is a transferable small submersible pump designed for continuous duty operation. This pump features a 1/4 in. MNPT discharge, 4.6 ft. shut-off head capability, and screened inlet. It’s supported by a 1/160 horsepower oil-filled, direct-drive motor that’s engineered for better lubrication and longer life while able to offer better heat protection. The motor in the small submersible pump is also impedance protected with higher impedance in the motor windings so that even if the motor locks, the increase in current (input) will be minimized and temperature will not rise above a certain level.
