First answer your question about the model:

There are many models of slurry pumps, and they vary from manufacturer to manufacturer.

200ZJ-60 200 represents: the outlet size of the pump is 200 mm, which is 8 inches;

ZJ, is actually a common model of slurry pump, ZJ series slurry pump It is a light slurry pump, generally suitable for medium to low concentration slurry transportation, and its abrasive performance is relatively in the low to medium range. It is generally used in the coal mine field.

60 represents the impeller diameter of the pump, in centimeters. In addition, this model is equivalent to the 200EZJ-A60 of Shijiazhuang Stone Pump Industry, where A represents the number of impeller blades, which is 5.

Working principle: It is a type of centrifugal pump. The centrifugal force is generated by the rotation of the impeller to achieve the purpose of slurry transportation.

ZJ slurry pump structure: pump body, pump cover and flow-passing parts: ZJ type slurry pump casing is a double-layer shell structure. The outer layer is a metal pump shell (front pump shell, rear pump shell), and its material is usually HT200 or QT500-7. The inner shell can be made of high chromium alloy cast iron (including sheath, front guard plate, rear guard plate) , or made of rubber (including front sheath, rear sheath).

Bearing assembly: The bearing assembly of the ZJ slurry pump adopts a cylindrical structure, which is convenient for adjusting the gap between the impeller and the front guard plate, and can be disassembled as a whole during maintenance.

Shaft seal (seal): The shaft seal types of ZJ slurry pump include packing seal, secondary impeller seal and mechanical seal.

Overall performance: This series of ZJ slurry pumps are mainly used to handle corrosive slurries containing solid particles, such as processing concentrates and tailings in mineral processing plants, removing ash and slag in power plants, and transporting coal slime in coal preparation plants. And heavy media coal preparation, coastal river sand mining operations to transport slurry, etc. The maximum weight concentration of the slurry processed by this series of ZJ slurry pumps is: 50% mortar and 60% slurry. Can be used in series according to user needs. ZJ slurry pump is one of the main product series of Shijiazhuang slurry pump and is a product independently developed in China.
