Product Overview
The DYZJ series slurry pump is a new generation of high-efficiency heavy-duty centrifugal slurry pump developed by our company based on years of mature experience in the research and application of advanced domestic slurry pumps, and on the introduction of advanced foreign technology, incorporating the technical advantages of similar foreign products. It is mainly used for the circulation transportation of volcanic FGD limestone, lime, and gypsum slurry, and is also used in industrial sectors such as metallurgy, mining, coal, building materials, and chemicals for transporting slurry containing corrosive solid particles. This series of products features a reasonable structure, reliable operation, and long service life.

DYZJ- Xiangdaoyuan Heavy-duty Slurry Pump
(K) - indicates a coated lining; if not indicated, the flow parts are all metal.
25- The design speed ratio of the pump divided by 10.
J - indicates a change in the rated speed of the pump.
A - indicates the first change in impeller outer diameter; A, B, C... and so on.
Structural Type
All-metal flow parts
Coated lining or rubber lining
The pump is a horizontal, single-stage, single-suction cantilever centrifugal slurry pump; this type of pump operates at high speed and uses a wide channel centrifugal impeller, with auxiliary blade structures cast on the back of the impeller; the pump cover adopts a rear pull-out structure. The pump body has replaceable wear-resistant metal lining or rubber lining, and the impeller is made of wear-resistant metal. The pump body can adopt different outlet angle directions according to user requirements.
Rear pull-out structure
The pump is connected to the motor or speed control mechanism through an extended diaphragm flexible coupling. During maintenance, it is not necessary to disassemble the inlet and outlet pipelines to withdraw the rotor components for maintenance.
The bearing body component adopts a bracket structure; the pump end uses imported double-row tapered roller bearings, while the drive end uses two disc cylindrical roller bearings. It is lubricated with thin oil.
The shaft seal adopts a cartridge mechanical seal.
Rotation Direction
When viewed from the drive end, the pump rotates clockwise. The rotation direction can also be changed according to user site pipeline installation needs.
Technical Features
Adopts excellent foreign hydraulic models and advanced computer simulation analysis technology (Solidworks, ANSY, Flowworks, etc.), ensuring reliable performance and high efficiency.
The material selection for the pump's flow parts is reasonable and advanced with a long service life. It is coated with KD.L-201 wear-resistant lining to meet the wear-resistant and corrosion-resistant requirements for transporting different media slurries.
Incorporates structural advantages from large domestic and foreign slurry pumps and mud boats; it features an advanced structure that is simple to maintain and operates reliably.
The bearing body adopts a simplified structure that adjusts the position of the impeller in the pump chamber by adjusting bearing components to keep the pump group in a high-efficiency operating state.
The shaft seal adopts a cartridge mechanical seal that is easy to install and maintain without requiring external clean industrial flushing water.
