High Chrome Slurry Pump uses high chrome white iron for the casing, impeller and wear plates. The chrome content is typically Cr27 or Cr28, with hardness above 600 Brinell. The wet end features a concentric casing with replaceable suction and gland side wear plates, and a closed impeller with pump-out vanes on front and rear shrouds to reduce recirculation. The discharge port can be rotated in 45° increments to adapt to different piping layouts. The pump is designed for maximum working pressure up to 600 PSI and is suitable for series or multistage installations.

FAQ
Q: What is the difference between High Chrome Slurry Pump and rubber-lined slurry pump?
A: High chrome pumps use metal wear parts, suitable for sharp, high-temperature, or high-speed slurries. Rubber-lined pumps use elastomer wear parts, better for small, smooth particles that bounce off the rubber surface. High chrome is generally recommended when slurry contains sharp mineral particles or operates at elevated temperatures.
Q: What is the typical chrome content in the wear parts?
A: The high chrome white iron used in slurry pump wear parts typically contains 27% to 28% chrome (Cr27/Cr28). This alloy provides a combination of wear resistance and corrosion resistance in mildly acidic slurries.
Q: Can this pump handle large solid particles?
A: Yes. High chrome slurry pumps are designed with large free passages and are available in various sizes. Solids handling capability depends on the specific model, with larger models accommodating particles up to several inches.
