Abstract
An improved cartridge-type pump provides inlets on each side of the pump to increase capacity from a material source disposed at one end of the pump housing. Moving pump gears are removed from a pump body to a lower end thereof and wear plates and gear ring define, in combination with a surrounding pump housing, upper and lower inlets of high volume capacity, respectively communicating between the material source at one end of the pump and both inlets of the pump. Increased intake to the upper inlet is provided, without internal machining of inlet ports in the lower end plate or the gear plate, and even though the gear plate is partially disposed in the housing sleeve between the upper inlet and the material source.
