T&E Outboard Pumps are all the same concept as our standard pumps, with the same great efficiency and superior sealing system. The intention of these pumps is to provide extra life when experiencing a higher amount of solids that you typically see. The external gear drive prevents the internal gears from touching thereby reducing wear on a part that has a high cost to replace. These pumps must be ran with an oil lubrication system. To see if an outboard pump is right for you please contact us and speak with a Customer Service Representative.
