Worthington CNG process pumps. Capacity to 5,000 gpm; heads to 475 feet. A proven and reliable pump for corrosive services in chemical, pulp and paper and general industry.
Longer lasting, easy to maintain and highly efficient pumps for the most rugged corrosive services. The CNG pump has proven itself through more than 25 years of service. This experience has been on some of the toughest applications such as evaporator service, furnace feed and fuming sulfuric acids. With the ever increasing demand on pump reliability you can continue to count on the "Old CarnpaigneC This line of corrosion-resistant pumps covers a wide range of services in the Chemical and Pulp & Paper industries. Twenty-nihe pumps are available for capacities up to 4,900 gpm, heads to 4 ft. For maximum interchangeability, all 29 sizes are mounted on only five basic bearing frames. These pumps are available with packed stuffing boxes or mechanical seals. The basic design allows for conversion from packed box operation to mechanical seal operation or vice-versa after the pump is installed. Design flexibility allows modifications for a wide range of temperatures and pressures. Bearings: pumps are equipped with anti-friction ball bearings. All bearings are sized to take the thrust and radial loads encountered and are designed for a minimum average life of years. system of deflectors, covers, and lip seals. Lubrication: standard is oil lubrication with a constant level oiler. Grease lubrication is also available. Impellers: semi-open with heavy vane sections ideal for slurries or solids. Balance ports and pump out vanes maintain low stuffing box pressure and balance thrust. Overall hydraulic design assures a low power requirement. Impeller is keyed to the shaft for added stability. Shafts: one piece and are ground on all critical surfaces. All shafts in this line are designed to transmit the power required and to withstand the radial reaction forces. In fact, on all pumps up to 0 gpm design capacity, the force on the shaft under worst conditions causes less than 0.002 inch deflection of the shaft at the impeller Large pumps have proportionately lower deflection. materials of construction pa rt Casing Suction head Shaft Impeller Gland Packing Seal cage Material Graphite-impregnated Teflon (TFE*) Teflon* *Registered trademark of E.

CNG PUMP WITH OPTIONAL EXPELLER Bearing protection: contaminants are excluded by a Lookat some of the features that have made the CNG the workhorse of the industry. Rugged frames: made of heavy cast iron with an STANDARD CNG PUMP 8 CNG-4 The expeller, positioned in a housing behind the impeller, is a sealing device that eliminates the need for packing or mechanical seals and a flush water system. The rotating expeller forces the pumped fluid away from the shaft and sleeve, eliminating leakage and virtually eliminating wear on these parts. Grease lubricated lip seals or packing rings are used as a static seal when the pump is not in operation. The 8 CNG 4 pump is an extension of the basic CNG line and also incorporates a large rugged bearing frame. The liquid end of the pump is separately supported so that the bearing frame, shaft, and impeller, together with the stuffing box head may be removed from the pump without disturbing the liquid end or suction and discharge piping connections. The expeller option can be retrofitted to existing CNG pumps in your plant. A retrofit kit consisting of an expeller and stuffing box can be introduced to your existing pump at low cost. The use of a twin volute construction drastically reduces bearing loading and shaft deflection over the complete pumping range and allows the pump to operate over wide capacity variations without difficulty.
