Product Overview

The Graco 652850 3300S FK/FK/FK/A Diaphragm Pump is a powerful air-operated double diaphragm (AODD) pump from the Husky 3300 series, engineered for demanding industrial fluid transfer applications. It uses compressed air to move fluids, allowing safe operation in environments where electric pumps may not be suitable.

Built with a durable stainless-steel fluid section and aluminium centre housing, this pump offers high flow capacity, reliable performance, and excellent chemical resistance. The configuration with FKM (fluoroelastomer) components provides strong resistance to oils, solvents, fuels, and aggressive industrial chemicals.

Key Features

Material Configuration (FK/FK/FK/A)

The material configuration code in the Graco 652850 model identifies the internal sealing and structural materials used within the pump:

• FK Seats – Fluoroelastomer seats designed for chemical resistance
• FK Balls – Durable FKM check balls for reliable sealing
• FK Diaphragms – Long-lasting diaphragms built to handle aggressive fluids
• A – Aluminium centre section for lightweight durability

Typical Applications

The Graco Husky 3300 diaphragm pump is widely used in industrial environments where large volumes of fluid must be transferred safely and efficiently. Its air-powered operation allows it to handle viscous fluids, abrasive materials, and hazardous chemicals without requiring electrical power.

• Industrial chemical transfer
• Bulk fluid handling operations
• Paint, coatings, and resin circulation systems
• Oil and lubricant transfer
• Wastewater and slurry pumping
• Manufacturing process fluid movement
