Genuine Koshin Volute Casing — Part No. 0121444
Product Overview
The Genuine Koshin Volute Casing (Part No. 0121444) is an Original Equipment Manufacturer (OEM) heavy-duty internal pump housing engineered specifically for Koshin 4-inch (100 mm) industrial trash pumps, including the KTH-100S and KTZ-100S series.
Cast from high-grade, abrasion-resistant iron alloy, this internal volute casing houses the main impeller and forms the core hydraulic compression chamber. It directs high-velocity fluid, mud, sand, and large solid particles efficiently into the upper discharge chamber while protecting the outer pump case from severe internal wear and cavitation damage.
