A sanitary pump with gear shaft bearing blocks in opposed cylindrical portions of a pump body bore, blocks constituting hand removable structural pump ends. Gear shaft bearings extending completely through blocks for easy cleaning, sealed by O-rings and clamp plates. Oval gear cavity bore between cylindrical portions of body bore extends only length of largest of interchangeable gears. Seals at end of gear cavity eliminate entrapment zones. Minimal intrusion of bearing blocks into gear cavity allows large operating temperature range. Shaft seals are contained in a hand removable cartridge. Complete pump disassembly by one manually operated clamp. Gear shaft diameters differ assuring correct assembly. Mount receives pump, tie rods sealing pump and securing to mount. Mount allows pump removal without changing pump-drive alignment. Pin and groove engagement of pump to mount allows 90&deg; interval pump ports orientation. Pump displacement is altered with interchangeable gears and drive end bearing blocks.

Sanitary design gear pump

Method and apparatus for the high speed dispensing of all beverages, and particularly carbonated beverages. The major elements of the device include a main flow control valve ( ) coupled to a pressurized container ( ) such as a beer keg, a positive shut-off filling nozzle ( ), a pressure control valve ( ) associated with the filling nozzle, and requisite control electronics and actuators to establish a dispenser operating sequence. A defined dose of beverage is dispensed by first closing the main flow valve, then briefly opening the pressure control valve, thereby lowering the hydraulic pressure in the nozzle to a desired pressure lower than that applied to the beverage container, then gently opening the beverage filling nozzle and immediately thereafter opening the main flow valve, maintaining the main flow valve in an open condition for a time required to produce a defined dose of beverage, and then rapidly closing the beverage filling nozzle while maintaining the main flow control valve in an open condition.
