Built for dependable performance, the CRT100 series pairs a cast‑iron construction with an open impeller design to handle slightly contaminated liquids while maintaining high throughput. The ceramic‑graphite mechanical seal and stainless steel shaft provide corrosion resistance and lower maintenance intervals, making this pump a cost‑effective choice for farmers, contractors, and light industrial users.
