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

A valve disabler for use in high pressure pipe cleaning systems. The valve disabler of the present invention serves to disable a single cylinder in a multi-cylinder plunger pump so as to generate pulsatile pressure surges within a hose member. The pulsatile pressure surges cause the distal end of the hose member to move in a serpentine manner, thus allowing the hose member to negotiate down a tortuous path within the pipe without stalling or becoming otherwise impeded.
