• Mining slurry and solids-handling setups
• Heavy-duty manufacturing fluid distribution units

Product Overview

The Graco 652161 is part of the Husky 3300 series, engineered for demanding industrial environments requiring high flow rates and dependable performance. This 3-inch air-operated double diaphragm (AODD) pump delivers efficient fluid transfer without electric motors, making it suitable for hazardous or explosive atmospheres when properly installed.

Built with an aluminium center section and fluid covers, along with neoprene diaphragms, this configuration offers durability, chemical compatibility, and long service life in tough applications.

Key Specifications

Performance & Application Benefits

• Handles high-volume fluid transfer with consistent output
• Capable of pumping fluids containing suspended solids
• Safe for hazardous environments (air-driven operation)
• Self-priming and dry-run capable
• Reduced downtime with durable diaphragm design
• Energy-efficient air valve system

How It Works

This diaphragm pump operates using compressed air to alternately move two diaphragms back and forth. As one chamber fills with fluid, the other discharges it. This continuous reciprocating motion ensures smooth, steady transfer of liquids without the need for mechanical seals, reducing maintenance requirements.

Installation Requirements

• Compressed air supply sized for 3" pump operation
• Proper BSP piping connections
• Mounting base or skid support
• Compatible fluid based on aluminium and neoprene materials
