Abstract
A piston displacement condiment pump for pumping viscous fluids, especially condiments such as ketchup, mustard, mayonnaise, relish, sauces and the like, is disclosed. The pump is constructed mostly of stainless steel and includes an inflow chamber with a check ball valve, an outflow chamber with a another check ball valve, and a spout. The pump includes an optional method for limiting the amount of condiment delivered with each stroke of the pump. The spout is held in place with a unique pin and L-slot arrangement, and by the unique position of the outflow chamber in relation to the cover. The spring and inflow check ball is attached to the piston and the outflow check ball is attached to the spring wire clip. The novel spring wire clip restrains the check ball valve in the outflow chamber.
