Pump Parts
Introduction
The slurry pump parts consists wet parts, sealing parts, bearing
assembly, pedestal and other parts.
In slurry pump, Wet Parts means the lining parts which contact with
fluid media, usually it include impeller, volute, frame plate,
throat bush. There parts will easily get corrosived or abrasived
when working and get repalced every periods.
Usually the pump parts are made of iron, steel, bronze, brass,
aluminum, plastic etc. For Slurry pumps they are normally made of
High chrome alloy, elastomer, polyurethane, ceramic and some other
customed. But High chrome alloy and elastomer are now the main
material for the slurry pumps. Recent years some companies are
trying to make wet parts by ceramics and many data come from labs
and mills show that the ceramic wet parts can work for a longer
time than high chrome alloy.
Slurry Pump Main parts:
• Impeller - front and rear shrouds have pump out vanes that reduce
recirculation and seal contamination.
Hard metal and molded rubber impellers are complete
interchangeable. Cast in impeller threads require no
inserts or nuts. High efficiency and high head designs are also
available.
• Liners - Easily replaceable liners are bolted, not glued, to the
casing for positive attachment and ease of
maintenance. Hard metal liners are completely interchangeable with
pressure molded elastomers. Elastomer
seal rings back all liner joints.
• Throat Bush - Wear is reduced and maintenance simplified by the
use of tapered mating faces to allow
positive accurate alignment during assembly and simple removal.
• Bearing assembly - A large diameter shaft with short overhang
minimizes deflection and contributes to long
bearing life. Only four through bolts are required to hold the
cartridge type housing in the frame.
