BOTTOM PORTING is recommended for pumping material containing solids which could settle out in the pumping chambers.
TOP PORTING is recommended if there is a possibility of entrapped air vapors inhibiting the pumping action.
Convert from one configuration to the other by rotating the outer chambers as indicated and substituting the proper pump base
(low base for top porting, high base for bottom porting).
