Product Overview

The ChemFlo® 1 Pedestal pump is built around a robust 316 stainless steel investment‑cast construction, ensuring long‑term integrity when exposed to harsh and corrosive environments. The internal wetted components – including the 6" enclosed impeller – are designed to optimize hydraulic efficiency while supporting high flow rates of up to 110 GPM (25 m³/h) at 3500 RPM. The enclosed impeller geometry improves fluid handling efficiency and supports higher heads, with the unit capable of delivering up to 140 feet (43 meters) of total dynamic head.

To enhance operational longevity, the pump is equipped with a Type 2100 mechanical seal featuring carbon, ceramic, and Viton components. This sealing system ensures reliable performance under varying thermal and chemical conditions, while additional optional seal configurations allow further customization for specialized environments.

The pump’s semi‑open/fully enclosed impeller architecture allows for the passage of solids up to 0.15" in diameter, providing operational flexibility in fluid streams with particulate presence. Its Pedestal (PumPak®) design offers interchangeability with both 56C and 145TC motor frames. When paired with a 145TC motor, the design requires a base‑mounted configuration to ensure optimal alignment and stability.

A variety of mounting options – including close‑coupled, pedestal, high‑speed hydraulic, and PumPak® formats – makes the ChemFlo® 1 suitable for both retrofits and new system integrations. The pump's broad performance range is further supported by multiple impeller trims, offering tailored hydraulic performance for specific duty points across commercial, industrial, and marine installations.
