General Introduction:
▶Designed for the continuous pumping of highly abrasive and/or corrosive slurries. These CNSME pumps feature a wide choice of replaceable hard metal or pressure molded elastomer
liners and impellers and are all interchangeable within the same casing. The centrifugal shaft seal is commonly used, but an interchangeable packed gland seal is also available for every pump. Special mechanical seals for slurry service are being developed.
▶This pump is perfect for difficult mill duties. It has a long wear life and is extremely cost-efficient. The use of effective liners makes this pump easy to maintain.
▶This is a heavy-duty slurry pump that is extremely durable and easy to maintain. It is highly efficient and corrosion and erosion resistant
▶Applications like fine tailings, coal, heavy slurry, Ni-acid slurry, Phosphoric acid, process chemical, pulp and paper.
▶The displayed pump is a 6/4AH rubber pump, with a centrifugal expeller seal. And the Ease of maintenance features include:
• Through bolt design
• Minimum number of casing bolts
• Slip fit replaceable Shaft sleeve
• Cartridge type Bearing Assembly
• Cast in Impeller thread
• Replaceable liners are positively attached
• Impeller Release Collar on large models
▶Another important subject about the shaft sealing is the Lubrication: In centrifugally sealed pumps, lubricate the static seal chamber sparingly but regularly, by means of the grease cup.
The grease for the centrifugally sealed pump static seal chamber should have the following specifications:
A lithium complex soap thickener grease with EP additives and oxidation inhibitors.
N.L.G.I. Consistency No 2; Drop Point 260 °C; Work penetration 25°C A.S.T.M. 265 – 295; RECOMMENDED GREASE: MOBIL HP or equivalent.
