SG group of pumps Model: SG/300G (14/12G-G)
Unlined Horizontal Pumps for Gravel SG/300G is featured by a metal casing with no separate liners and no elastomer wear parts. The design features a hard metal casing and wear components and is capable of passing extremely large particles. They are typically used for pumping gravel, dredging, or pumping solids that are too large to be handled by type SH pumps. SG gravel pumps adopt larger impellers and heavier casing construction. Sizes range from 100mm to 400mm.

Optimizing Slurry Pump Impeller Design for Efficiency and Reliability
Slurry pump impeller design is a crucial element in the efficient and reliable transport of abrasive and erosive fluids across numerous industries. These specialized pumps are vital in mining, wastewater treatment, chemical processing, and even food production, where handling mixtures of liquids and solids is commonplace. Optimizing the impeller's design directly impacts the pump’s performance – its efficiency, longevity, and ability to withstand the harsh conditions inherent in slurry handling. Understanding the nuances of slurry pump impeller design is therefore paramount for engineers and operators striving for cost-effectiveness and operational excellence. Globally, the demand for efficient slurry handling solutions is constantly increasing, driven by factors such as expanding infrastructure projects, stricter environmental regulations regarding waste management, and the growing need for resource extraction. The United Nations estimates that global wastewater generation will increase by 54% by 2050, necessitating advanced wastewater treatment facilities – many relying heavily on robust slurry pumping systems.
