A pump is disclosed. The pump may have a housing, and a body disposed within the housing and at least partially defining a plurality of barrels. The pump may also have a plurality of plungers associated with the plurality of barrels, and a plunger engagement surface. The plunger engagement surface may have geometry configured to reciprocate the plurality of plungers within the plurality of barrels as the plurality of plungers rotate relative to the plunger engagement surface, and a plurality of undulations configured to reduce a flow pulsation of the pump.
