PosiTiVe DisPlAcemenT PumPs
gPb series and sPo series
GROCOy Vane Pumps are self-priming, are instantly reversible, and are capable of operation
in either direction. Relatively high flow (more than gear pumps) makes them suitable for general
purpose duties such as deck-wash, bilge pumping (filtered inlet), 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. SPO-80 Series Vane Pumps
have a more powerful motor and are better suited for long run-time or head pressure greater than 20 PSI.
