Why Choose Graco SaniForce Sanitary Piston Pump

The Graco SaniForce sanitary pneumatic piston pump features FDA-compliant food-grade materials and a hygienic design. When other pumps struggle with high-viscosity materials, SaniForce delivers up to 102 kgf/cm² (1450 psi) of working pressure—ideal for concentrated sauces, syrups, and other viscous fluids. Its unique pneumatic motor with back-pressure shutoff allows self-priming and dry-run operation, reducing downtime, maintenance, and overall operating costs.

Ultra-Clean Performance: SaniForce Merkur Sanitary Motor

The SaniForce Merkur sanitary motor features polished fluid-contact surfaces to prevent residue buildup. Its fully enclosed design isolates all moving parts from the external environment, eliminating contamination risks and ensuring compatibility with CIP (Clean-In-Place) and SIP (Steam-In-Place) processes. With low lubrication requirements and optional oil-free operation, it prevents lubricant contamination and guarantees product purity and safety.

Unmatched Safety and Reliability: Dry-Run, Self-Priming, Back-Pressure Shutoff

The SaniForce sanitary piston pump features self-priming for easier startup and faster fluid transfer. It can safely run dry without causing damage if fluid supply is interrupted. Its unique back-pressure shutoff automatically stops the pump when the outlet valve closes, preventing over-speed and mechanical damage while ensuring operator and process safety.

Maintenance-Friendly Design: Quick-Disassembly and FDA-Grade Guard

The SaniForce piston pump is designed for efficient maintenance in sanitary production lines. Its lower components are quick-disassembly and made of corrosion-resistant stainless steel, allowing frequent and easy hygienic cleaning. The pump also features a removable, FDA-compliant, washdown-ready guard, giving users easy access to inspect and clean the air and pilot valves.

Dual Design Options: Handling Different Viscosities and Materials

The SaniForce piston pump series offers two designs to suit various fluid viscosities and properties:
• Double Ball Design：Ideal for low to medium-viscosity fluids, ensuring one-way control during intake and discharge.
• Priming Piston Design：Enhances priming for high-viscosity or difficult-to-flow fluids, actively pushing material into the pump to prevent cavitation and startup issues when handling thick materials.
