75 / 475 Series Viking Motor Speed Pump Product Line details

For compactness, less weight and simplicity of mounting, Viking’s line of close-coupled pumps are ideal for direct connecting to other pieces of equipment. The positive, smooth delivery of these pumps makes them preferred for many types of applications including filtering, circulating, transferring, lubricating or booster service.

The five sizes of Viking close-coupled pumps from 5 to 30 GPM are available in this unmounted type ready to connect on other equipment with standard NEMA C flange mounting.

All pumps are available with rotor bore to fit the shaft of a standard motor or other piece of equipment. Bores are furnished in ⅝” and ⅞”. By using a full length key between drive shaft and rotor bore, rigid and positive alignment of pump and drive shaft is assured.

This advanced design is unique in its field for it permits use of STANDARD, unmodified NEMA C flange ball bearing motors. It is extremely close-coupled, reducing needed space, cutting overall weight, eliminating bases, couplings, outboard bearings or any drive equipment and at the same time saves cost.

All sizes are equipped with opposite ports. Only two casing sizes are used for all five pumps. The two smaller pumps use one casing and the three larger pumps use the other.

Pumps are built to accept a compact, integral relief valve mounted on top of casing to maintain extreme compactness.

All pumps are available with either mechanical seal suitable for 100 PSI pressure or a lip seal suitable for 50 PSI. No modification of parts are needed to convert from one seal to the other.

Industry application include Plastics, Abrasives, Sealants, Adhesives, Agricultural, Asphalt, Biodiesel, Brewing, Beverage, Chemical, Chocolate, Ethanol, Fats & Oils, Fiber, Food, Fuels, Fuel Oils, Oil Production & Refining, Paints & Coatings, Personal Care Products, Pharmaceuticals, Polymers, Polyurethane foam, Printing Inks, Pulp & Paper, Refrigeration, Rubber, Sugar, Soaps & Detergents, Water Treatment, Wind Power.
