ZJ Type Wear-resistant Slurry Pump

The ZJ type pump adopts a vertical mid-opening and double pump casing structure. . The outer layer is a sturdy metal pressure-bearing shell (usually made of ductile iron or gray cast iron), and the inner layer is a replaceable high-chromium wear-resistant alloy (such as Cr26-Cr28) for flow-through components (including the impeller, front/back guard plates, and sleeve). . This design not only ensures the overall structural strength but also makes it convenient to replace the inner liner after wear, significantly reducing maintenance costs. The pump's water outlet can be rotated at 45° intervals to eight different positions for installation, meeting the requirements of various pipeline layouts.

Outstanding wear resistance and corrosion resistance: The flow components are made of high-hardness high-chromium wear-resistant alloy, which can effectively resist the intense scouring and wear caused by solid particles, and have a long service life. . According to the characteristics of the medium, other wear-resistant materials such as rubber can also be selected. .
Strong flow-through capability and anti-clogging performance: The impeller adopts a wide flow channel and low rotational speed design, allowing for the passage of larger solid particles (with the maximum particle size reaching 30%-50% of the pump diameter). It is not prone to clogging and is suitable for transporting slurries containing coarse particles. .
High efficiency, energy saving and stable operation: Utilizing an optimized hydraulic model, it has high efficiency and excellent cavitation performance. . The pump shaft is highly rigid, and the bearings are equipped with high-strength rolling bearings to ensure smooth operation, low vibration and low noise. .
Reliable sealing system: Mainly adopts the combination of auxiliary impeller and packing for sealing. . The centrifugal force generated by the secondary impeller can balance the pressure at the shaft seal, significantly reducing the leakage of the slurry, and also providing a mechanical seal option to adapt to different working conditions.

Electric power industry: Water removal and ash discharge from thermal power plants, as well as the transportation of limestone/gypsum slurry in the flue gas desulfurization (FGD) system .
Coal industry: Coal sludge from coal washing plants, heavy medium (heavy media) transportation, and water coal slurry transportation .
Metallurgical industry: Slag from smelting plants, slag water, and transportation of wet-process metallurgy mineral slurries .
Building materials and chemicals: Transportation of slurry in cement plants, glaze in ceramic plants, and corrosive slurry in chemical plants
