Applications
Typical applications for the 935136C pump include Beverage Cooling, Brine Injection, Blending for fracking, Dosing pumps for organic and inorganic chemicals, Circulation pumps for hydraulic fluids, Underwater pumps for deep sea ocean applications, Transfer pumps for additives or alcohols or lyes or bases, and many other applications. This pump is designed to handle common and highly corrosive liquids that must be pumped under pressure. It is manufactured to an extremely precise tolerance, this pump will prevent system contamination while maintaining the purity and integrity of the liquid being pumped. Typical liquids pumped are adhesives, resins, catalysts, odor control additives, fertilizers, polymers, flocculants, caustics, hydrochloric acid, solvents, biocides, dyes, bleaching chemicals, detergents, and many more liquids. These gear pumps are frequently relied upon for product transfer. They can handle both high and low viscosity and high and low temperature fluids including liquefied gasses. The selection of this pump to fit a given application depends upon full knowledge of the application including both system parameters and fluid properties. As a metering pump, when mounted to a variable speed motor and controller, a gear pump offers several advantages over reciprocating type metering pumps. Unlike other reciprocating type pumps, gear pumps offer nonpulsating flow. Piping is simplified, because pulsation dampeners and back pressure valves are not required. Liquids, which have a tendency to gas off, create priming difficulties with the reciprocating type pumps. Since gear pumps are inherently self priming and their nonpulsating flow does not agitate the liquid, they may be better choices for these applications. To achieve successful operation and maximum life from your pump make sure that the pump is compatible with the service and operating conditions of your application. The pump materials of construction and other details are specified by the pump model number. This gear pump accepts standard NEMA 56C and 143/5TC motors. This enables the pump to be close coupled which provides greater assembled strength, complete enclosure of all moving parts, and a compact design. This also eliminates the need for special base plate mountings, couplings or complicated drives. This pump can also accept standard large flange C face IEC metric motors with feet in 71, 80 and 90 L frame sizes. Bracket codes are C1 for a 56C frame motor mount Adapter bracket, C2 for a 143TC/145TC frame motor mount Adapter bracket, C3 for a IEC 71 B14 frame motor mount Adapter bracket, C4 for a IEC 80 B14 frame motor mount Adapter bracket, C5 for a IEC 90 B14 frame motor mount Adapter bracket, C6 for a 182TC/184TC frame motor mount Adapter bracket, and C7 for a IEC 100 B14 frame motor mount Adapter bracket. The motor bracket is sold separately.
