Longer Life: Proprietary High Vanadium Stainless Steels and other best-in-class materials are used to dramatically increase the wear and corrosion resistance of the pump.
Porting:
Plates port to same side. Parker Prestolok fitting adapters supplied for flexible tubing. Inlet - 6mm OD, Outlet - 4mm OD
Uniform Accuracy: The application of new design criteria insure that all the internal components wear uniformly over the life of the pump—no stream will loose its accuracy before any other.
Materials of Construction:
Proprietary High Vanadium Stainless Steel provides best-in-class corrosion and wear resistance. Seal and binder screws, alloy steel
Less Bubble Formation: The use of special Parker fittings, provide a constant port size from the pump, through the fitting and into the tubing, with a special O-ring seal to eliminate stagnation and air drawn bubble formation.
Seal:
Stainless steel spring energized Nitrile lip seal standard
Spin Finish Gear Pump System
