Ceramic Slurry Pump Parts
Ceramic Slurry Pump Parts:
The impeller is the main rotating componenwhich normally has vanes to impart and direct the centrifugal force to the liquid.
Closed Impeller
Impellers are generally closed because of higher efficiencies and are less prone to wear in the front liner region.
Efficiency Francis Vane
Some advantages of the Francis vane profile are the higher efficiency, improved suction performance and slightly better wear life in certain types of slurry because the incidence angle to the fluid is more effective.
Concave Designed
The impeller is concaved designed, the pressure around the shrouds will be lower, so it will have a better wear performance.
Material
The wet parts are made of silicon carbide ceramic by sintering processing, which will give the pump exccellent wear and corrosion resistan performance, and it can also resistant impact by large particles(<15mm) in slurry. These are what metal alloy pump can not do.
– Wear resistant
– corrosion resistant
– Stand impact
For 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.
For chrome alloy material, the common type is High chrome Alloy(27%Cr), it can be used from Ph 5 to 12, and its hardness can be to HRC58, which is a very good choice for slurry control and transport. But in some conditions, the Ph may lower than 5, then we try BDA49, it can lower to Ph4, mostly used in FGD processing.
The elastomer are widely used in fine slurry conditions and lower Ph to 2. There are also many rubbers for different conditions, such as RUBBER 08, RUBBER 26, RUBBER 55, S02, etc.
And recently, Polyurethane becomes popular in some conditions. It is good at corrosion and wear conditions.
What’s more Ceramic material for slurry pump is perfect to replace elastomers and polyurethane in some condition. High Hardness and great corrosion make it even can replace the metal impeller in some conditions.
The most important things for stopping ceramic slurry pump to replace other ones are the price and friability. But some companies have solved these problems, that is to say some companies have made it success to manufacturing ceramic slurry pump that can stand impact by particles in the fluid media and the pump is not such expensive.
