6 / 4 D Metal Lined Slurry Pumps driven by Electric Motors through Belts and Pulleys
Introduction:
Advantages and Uses of Series ‘A’ Type '' Slurry Pumps:
Designed for the continuous pumping of highly abrasive and/or corrosive slurries. These pumps feature a wide choice of replaceable hard metal or pressure moulded 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.
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
Centrifugal Sealing - 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.
