A quick disconnect pump assembly is disclosed. The pump assembly includes a housing with inlet and outlet ports, an elongate slot, and a retainer channel. A sliding lock moves within the slot between a locked position and an unlocked position. The sliding lock includes inlet and outlet port openings and a sliding lock retainer opening. The inlet and outlet port openings each engage and retain a removable fitting when the sliding lock is in the locked position, but do not engage or retain the removable fitting when the sliding lock is in the unlocked position. The pump assembly also includes a sliding lock retainer which passes through the sliding lock retainer opening to prevent removal of the sliding lock from the elongate slot. A fluid pump and a beverage dispenser utilizing the pump assembly are also disclosed.
