The GRACO SP3B.0042 is a 3-inch sanitary air-operated double diaphragm (AODD) pump designed for hygienic fluid transfer in food, beverage, pharmaceutical, and chemical processing. It features a sanitary stainless steel fluid section and is engineered for high sanitation standards.

Key Features:

• Air-Operated Double Diaphragm (AODD) Pump
• SaniForce 2.0 HS-Series, 3"
• Sanitary stainless steel fluid section, stainless steel center section, EPDM overmolded diaphragms (3A approved), FKM (Fluoroelastomer) balls, EPDM manifold O-rings
• Up to 150 gpm (567 lpm) or higher depending on configuration (some sources list up to 230 gpm/870 lpm for similar models; for SP3B.0042, flow rate is not explicitly specified in available listings, but likely similar to SP3B.0024 at up to 150 gpm/567 lpm or higher)
• Up to 125 psi (some sources list up to 100 psi for similar models; for SP3B.0042, pressure handling is not explicitly specified in available listings, but likely similar to SP3B.0024 at up to 100–125 psi)
• Designed for use with GRACO SaniForce 2.0 HS-Series equipment and compatible with hygienic process lines
• High Sanitation (32 Ra), 3A approved diaphragms
• Seal-less diaphragm pump design eliminates leaking
• Single piece manifolds reduce tri-clamps and gaskets
• Handles solids up to 3.8" (96.5 mm) in diameter
• Reliable, easy to maintain, and suitable for continuous duty cycles

Applications:
Ideal for transferring sensitive fluids in food, beverage, pharmaceutical, and chemical industries where high sanitation and reliability are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compliance with industry standards.
• Ensure all connections are properly tightened and leak-free
• Follow GRACO’s recommended installation procedures for sanitary pumps
• Regularly inspect diaphragms and seals for wear and replace as needed
• Use only compatible fluids and cleaning agents to maintain pump integrity
• Perform routine inspections and maintenance as per GRACO guidelines
• Replace diaphragms and seals at recommended intervals
• Clean pump thoroughly after use, especially in food and pharmaceutical applications
