Defoam Centrifugal Pump

Technical Features: Open Impeller Design – Self-Venting Capability – Gas-Liquid Two-Phase Flow Handling

Product Overview

The SF Series is engineered specifically to tackle the challenge of conveying "gas-liquid mixtures" in industrial processes. Distinct from traditional closed impeller pumps, this equipment features a semi-open or fully open wide-channel impeller, combined with a specialized inducer or venting structure. It effectively breaks down foam structures and separates entrapped gas, making it the ideal choice for handling unstable fluid flows.

Technical Highlights

Specialized Inducer Structure

The pump inlet undergoes rigorous hydrodynamic optimization. Even under conditions of extremely low inlet pressure or high foam generation, it smoothly draws in material, demonstrating superior anti-cavitation performance.

Shear De-foaming Capability

The high-speed rotating open impeller exerts a mechanical shearing effect on incoming foam. This assists in breaking down large air bubbles during transport, thereby increasing fluid density and ensuring stable output pressure.

High Passability (Non-Clogging)

The wide flow channel design not only facilitates gas venting but also tolerates fluids containing minor solid particles (such as fibers or starch residues), significantly reducing the risk of clogging.

Reliable Sealing System

Equipped with a double mechanical seal and a flush/cooling system. This prevents dry running and overheating of the seal caused by gas accumulation, ensuring leak-free operation.
