Gold Mining Pump – Pump Casing
Product Name: Gold Mining Pump - Pump Casing
Material: High-chromium alloy Cr26
Applicable fields: Placer gold mining and beneficiation, slurry transportation. Pipe diameter: 6-10 inches (customizable according to drawings)
Technological Breakthroughs in Thickened Pump Casings and Their Wear-Resistant Advantages：
The pump casings of conventional gold-dredging pumps are typically made of ordinary cast iron or low-alloy materials, with a thickness usually ranging from 10 to 15 mm. When used over the long term to handle mineral slurries with high sand content, these casings are prone to perforation or deformation.
Material Upgrade: The material used is high-chromium cast iron (Cr26), with a hardness reaching HRC58-62, offering wear resistance more than three times greater than that of conventional materials. Combined with a dual-layer cladding process, a 2-3mm wear-resistant coating is applied to critical flow areas (such as the volute outlet and impeller chamber), further extending the service life.
Structural Reinforcement: The overall thickness of the pump casing has been increased to 20–25 mm, and the internal flow passages have been optimized through fluid simulation to reduce the impact of turbulence on the casing. Measured data show that after continuous operation for 800 hours in a slurry containing 30% quartz sand, the wear rate is only one-fifth that of conventional pumps.
Application scenarios
Gold mining: Primarily used to extract gold-bearing slurry from riverbeds, mine pits, and other locations, which is then transported to gold-dressing equipment. The gold is extracted through processes such as screening and concentration.
Other mining applications: In addition to gold mining, sluice pumps can also be used in various mining scenarios that involve pumping slurry containing solid particles—for example, during the extraction of copper and iron ores, where they are employed to transport the slurry.
Wear Resistance: Since the medium being conveyed contains a large number of solid particles such as sand and gravel, which cause significant wear to the pump’s flow components, the impeller, pump casing, and other parts of gold mining pumps are typically made from wear-resistant materials like high-chromium alloys to extend their service life.
