The GRACO D44331 is an air-operated double diaphragm pump designed for reliable fluid transfer. It features a polypropylene center section, stainless steel (S/S) seats and balls, and a PTFE diaphragm. This pump is intended for use in demanding industrial environments where leak-free, robust, and easy-to-service fluid handling is required.

Key Features:

• Air-operated double diaphragm pump
• Husky 716 S/S (3/4" NPT)
• Polypropylene center section, stainless steel seats and balls, PTFE diaphragm
• Maximum free flow delivery: 16 gpm (61 lpm)
• Maximum fluid working pressure: 100 psi (7 bar, 0.7 MPa)
• Center- and end-porting for flexible installation
• No mechanical seals, reducing risk of fluid leaks or failures
• Runs quietly at less than 85 dBa with remote muffler capability for even lower noise levels
• Easy-to-service air valve and ball checks
• External controller for remote control capabilities

Applications:
Suitable for transferring a wide range of fluids in industrial settings, including those requiring robust, leak-free, and easy-to-maintain pumps. Commonly used in manufacturing, chemical processing, and other environments where reliability and ease of service are critical.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the pump
• Connect air supply within the specified pressure range (30 to 100 psi, 2.1 to 7 bar)
• Use appropriate fittings and hoses for fluid and air connections
• Regularly inspect and service air valve and ball checks for continued reliability
