Application and Features:
Type BM, BH, slurry pumps are cantilevered, horizontal, centrifugal slurry pumps.They are designed for the handling highly abrasive, high density slurries in the metallurgical, mining, coal, power, building material and other industrial departments etc.The pumps of this type also may be installed in multistage series.
The frame plates for the type BM, BH pumps have replaceable wear-resistant metal liners or rubber liners.The impellers are made of wear-resistant metal or rubber.
The shaft seals for type BM, BH, pumps may be adoptable of gland seal or expeller seal.The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.
Brief Introcustion to Pump Type Selection:
Refering to the performance curves of the pump the selected capacity range should be as follows:
Pump Type BM, BH: 40-80% for higher density, strong abrasive slurries
40-80% for medium density, medium abrasive slurries
40-120% for lower density, lower abrasive slurries

Not only does Boda offer the complete pumps, we also offer the spares for all series pumps, they include
-Impeller
-Metal Liner
-Rubber Liner
-Bearing Assembly
-Base
-Cover Plate & Frame Plate
-Others
The pump parts can be made of high chrome, a wide variety of elastomers or the latest in ceramic materials for longer service life and higher efficiency.
Materials Offered:
-High Chrome Cast Iron
-Ductile Iron
-Stainless Steel
-Natural Rubber
-Specific Rubber
-Polyurethane
Impellers - higher efficiency rates (up to 90+ %) - pump out vanes to reduce recirculation within pump, and aid in preventing seal contamination; impeller clearance is adjustable to maintain efficiency over the life of the part.
Liners - alloy or thick elastomer liners provide superior erosion and corrosion resistance
Expeller (Centrifugal Seal) - no external sealing water required where applicable
Stuffing Box - flushed gland sealing with braided packing and a lantern ring
Mechanical Seals
Bearing Assembly
Cartridge-style bearing housing allows for removal from pump and assembly in controlled environment
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.

The properties of the rubber material:
We have variety of natural rubber and elastomers, which can be used for pumping corrosive or acid slurries. But the rubber material is not suitable for slurries which contain sharp solids.
When the slurries contain fine particles, the rubber material features good performance of wear resistant.
The properties of the high chrome white iron:
We have variety of high chrome white iron, and the content of chrome is different.
They can offer excellent performance under erosive conditions. The alloy can be effectively used in a wide range of slurry types. The high wear resistance of alloy is provided by the presence of hard carbides within its microstructure. Some special high chrome alloy is also suited to application where corrosion resistance, as well as erosion resistance is required.
