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. 

BHR Rubber Lined Slurry Pump
BH(R) series centrifugal slurry pumps and spare parts can fully interchage with world famous brand. These pumps are of heavy-duty construction, designed for continuous pumping of highly abrasive and corrosive slurries. They feature a wide choice of replaceable abrasion resistant metal or moulded elastomer casting liners and impellers, which are all interchangeable within a common costing assembly. 

BG(H) Gravel Sand Slurry Pump
Type BG(H) gravel pumps are designed for continously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by common pump. They are suitable for delivering slurries in Mining, Explosive sludge in metal melting. Dredging in dredger and course of rivers, and other fields. Type BGH pumps are of high head ones. 
 
Construction of this pump is of single casing connected by means of clamp bands and wide wet passage. The wet parts are made of Ni-hard and high chromium abrasion-resistance alloys. The discharge direction of pump can be oriented in any direction of 360 degree. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion-resistance. 

BV Vertical Sump Slurry Pump
BV pumps are vertical, centrifugal slurry pumps submerged in sump to work. They are designed for delivering abrasive, large particle and high density slurries. These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties. Wet parts of type BV pump are made of abrasion-resistant metal. All parts of type BVR pump immersed in liquid are lined with rubber outer liner. They are suited to transport non-edge angle abrasive slurry. 
 

The ZJseries pumps are cased in hard-alloy which is a high anti-wear and high anti-corrosive impact resistance material, which means the pump will have a longer service life. Inaddition, this series pumps used an automatic reduced pressure system to avoid liquid leakage.
