ZJ Type Slurry Pump's Flow Passage Components

The flow components of ZJ slurry pump refer to the core parts assembly in the ZJ type horizontal slurry pump that directly come into contact with the slurry, and are subjected to wear and corrosion. They mainly include the impeller, the casing (casing lining), the front guard plate, the rear guard plate, the shaft sleeve, etc. The flow components of the ZJ slurry pump are supplied as complete sets according to the pump model and diameter. The common matching diameters range from 50 to 400 mm, with a flow rate of 10 to 2000 m³/h and a head of 10 to 100 m. The material of the flow components, apart from the standard high-chromium cast iron, can also be selected as duplex stainless steel (2205/2507) to cope with corrosive and wear-resistant combined conditions, or ultra-high chromium Cr30 to deal with extreme wear (such as quartz sand, iron concentrate). Each part is precisely cast, heat-treated, and processed according to the original factory drawings to ensure the assembly accuracy and interchangeability with the pump body and bearing frame.

High-chromium alloy material, long wear life: The impeller, sleeve, and guard plate are all made of KmTBCr27 high-chromium cast iron. The metallographic structure is martensite + carbides, with a hardness of HRC ≥ 58. It can resist high-speed erosion from quartz sand, iron ore, coal slag, etc., and has a service life 5 to 8 times longer than that of ordinary HT250. It is the key to keeping low operating costs for the ZJ series slurry pumps.
Double pump shell structure, only replace the inner liner without replacing the outer shell: All the flow components of the ZJ slurry pump are inner liner parts. After wear, only the impeller, sleeve, and guard plate need to be replaced. The outer pressure-bearing pump shell can be used for a lifetime and has a 30% to 40% lower total life cycle cost compared to single-shell pumps.
Hydraulic model optimization, high efficiency: The impeller adopts advanced hydraulic design, with a small number of blades (3 to 5) and a wide flow channel. It can pass through the maximum solid particle diameter up to 60% to 80% of the outlet diameter while maintaining an efficiency of 82% to 88%. It is 5% to 10% more energy-efficient than old-style slurry pumps.
High interchangeability, universal spare parts: The ZJ series is a nationally jointly designed product. The installation dimensions of the flow components for the same diameter are completely interchangeable with pumps of various brands. Users can replace without modifying the foundation.
Material upgrade is possible: Standard Cr27 high-chromium; extreme wear can be selected as Cr30 ultra-high chromium; corrosion + wear conditions can be selected as duplex stainless steel 2205/2507; for fine particles with low wear, rubber inner liner (it needs to be confirmed if it is compatible with the ZJ shell).

The purchasers of the flow components of ZJ slurry pumps are mainly the spare parts warehouses and maintenance departments of slurry pump users in mining beneficiation plants, coal washing plants, power plants, and dredging projects. The specific scenarios are as follows:
Mining beneficiation plants: Tailings transportation and concentrate circulation for iron ore, copper ore, and gold ore. The flow components need to be replaced every 3 to 6 months, accounting for the majority of the annual spare parts budget of the beneficiation plant.
Coal washing plants and power plants: Coal slurry water transportation in coal washing plants and ash slurry transportation in power plant ash discharge and slag removal systems. The slurry contains high solid concentration and hard particles, and the flow components wear out quickly, requiring a regular inventory.
River dredging and sand extraction: ZJ slurry pumps for suction dredgers. The flow components are strongly eroded by river sand (quartz), requiring high-chromium or ultra-high-chromium materials.
Chemical and metallurgical industries: Oxide aluminum red mud, phosphoric acid slurry, steel slag treatment, etc., which involve both corrosion and wear conditions. Dual-phase stainless steel flow components need to be selected.
