Corporations and Tubing Connections

LMI has simplified their tubing connection system to allow for smaller inventories of valves and fittings. Connecting to 1/4″, 3/8″, or 1/2″ tubing simply means having a standard coupling nut and an appropriately sized tubing ferrule. LMI also makes injection corporation stop nozzle assemblies for 3/4″ or 1″ male pipe thread or 1″ AWWA/CC thread taps, which make for easy servicing and removal of the injection check valve without shutting down the line.

Flomotion Peristaltic Pumps

Peristaltic pumps use positive displacement in the form of rotors compressing a section of flexible tubing and forcing liquid through the tube. This design allows for easier pumping of viscous or aggressive fluids, the pump stays primed more easily than diaphragm-type pumps, and maintenance is much easier as there are no valves or seals to regularly replace.
