GP Series Gear Pump

GP Series Gear Pump


Made in the USA, GROCO Gear Pumps are self-priming, instantly reversible, and are capable of operation in either direction.  Relatively low flow (less than vane pumps) makes them suitable for duties such as deck-wash, fuel transfer, ballast transfer, and oil change. All models have an ignition protected motor, #316 stainless steel shaft, and are available in models that provide reversing (R), remote reversing (RR), and reversing with touchpad (RT) control options.
