The GRACO D3A335 Husky 307 is a 3/8" BSP air-operated double diaphragm pump with an acetal fluid section, polypropylene center section, stainless steel seats and balls, and a TPE (Hytrel) diaphragm. It is designed for reliable, low-pulsation transfer of a wide range of fluids, including those requiring grounding for static dissipation, and is commonly used in chemical, paint, and process applications.

Key Features:

• Air-operated double diaphragm pump
• Husky 307, 3/8" BSP
• Acetal fluid section, polypropylene center section, stainless steel seats and balls, TPE (Hytrel) diaphragm
• Up to 7 gpm (26.5 lpm)
• Maximum fluid discharge pressure: 100 psi (7 bar, 0.7 MPa)
• Compatible with a wide range of fluids, including chemicals and paints; suitable for applications requiring grounding
• Stall-free low pulsation air valve for smooth and rapid changeover
• Easy-to-service air valve and ball checks
• Quick and easy assembly/disassembly
• Operates on as little as 20 psi (1.4 bar, 0.14 MPa) air pressure
• Split manifold option for pumping multiple fluids without mixing
• Every pump tested prior to shipping
• Groundable acetal model for static dissipation

Applications:
Chemical transfer, paint/solvent transfer, wastewater/pH control, batching/dosing, and other process applications requiring reliable, low-pulsation fluid handling.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump, as well as compatibility with GRACO equipment.
• Ensure proper grounding of the acetal fluid section for static dissipation by attaching the ground wire to the grounding strip.
• Follow manufacturer guidelines for air supply and pressure settings.
• Regularly inspect and service air valve and ball checks for reliable operation.
• Use appropriate fittings and hoses rated for the intended fluid and pressure.
• Perform routine maintenance as recommended by GRACO.
• Check for leaks and wear during operation.
• Use only compatible fluids and avoid exceeding maximum pressure ratings.
• Consult the manual for detailed installation and maintenance procedures.
