Banjo Pumps:
RUN DRY WITH WET SEAL
With a specially sealed reservoir, wet Seal pumps enable you to use the pump while running dry and not damaging the engine or pump assembly. This design feature helps you get up and running, yet safeguards the pump when the liquid flow stops. Wet Seal is an option for poly, cast iron, and stainless Banjo pumps.
