Product Name: Food Grade Lubricant / NSF H1 Grease (Part No. 400034-2)

Description:
This component is a specialized food-grade lubricant, specifically formulated for high-pressure waterjet cutting systems . It is an NSF H1 registered, non-petroleum-based grease designed for use in environments where incidental food contact may occur . It serves as a critical maintenance consumable for the assembly, lubrication, and protection of O-rings, dynamic seals, bearings, and sliding components .

The lubricant is engineered to withstand the extreme conditions of waterjet operation, including high pressure loading (up to 60,000–90,000 PSI), water washout, and temperature fluctuations . It provides excellent adhesion to metal surfaces, reduces friction during assembly, and enhances the sealing performance of critical components . Unlike standard greases, this food-grade formulation is safe for incidental food contact, making it ideal for cutting applications in the food, beverage, pharmaceutical, and hygienic industries . It is compatible with H2O Jet systems and major waterjet brands including KMT, AccuStream, FLOW, OMAX, and WSI.

Applications:

• Lubricating O-rings and dynamic seals during installation into high-pressure cylinders, intensifier pumps, and on/off valve assemblies 

• Coating bearings, bushings, slides, and guides in the waterjet motion system 

• Protecting plungers, pistons, and valve components from corrosion and wear during assembly and storage 

• Used as a seal installation aid to prevent rolling, pinching, or tearing of delicate elastomer seals 

• Applicable in food processing, pharmaceutical manufacturing, and other hygienic cutting environments where lubrication must be safe for incidental food contact 

Features:

• NSF H1 Certified: Registered for use in food processing areas where incidental food contact may occur 

• Ultra-High Pressure Stability: Formulated to withstand continuous operation at 60,000–90,000 PSI without breaking down 

• Water Washout Resistance: Maintains lubricity and protection even in high-moisture waterjet environments 

• Corrosion Protection: Provides a durable barrier against rust and chemical degradation on metal components 

• Non-Staining Formula: Clear, tasteless, odorless, and non-irritating; will not stain materials or products 

• Wide Temperature Range: Effective from -30°C to +160°C, suitable for diverse operating conditions 

• High Shear Stability: Resists thinning under mechanical load, maintaining viscosity in bearings and seals 

• Consumable Classification: A maintenance consumable that must be replenished during every seal or component service 

Maintenance:

When to Use:

• Every Seal Replacement: Apply a thin, even layer to all new O-rings and dynamic seals during installation or pump rebuild 

• Valve Assembly: Use during the assembly of on/off valves, check valves, and hydraulic cartridges to ensure smooth component fitment 

• Bearing and Guide Lubrication: Apply to linear guides, bearings, and sliding components as part of routine machine lubrication 

• Component Protection: Coat spare parts with a thin layer to prevent corrosion during storage 

Application Guidelines:

• Thin, Even Application: Apply only a thin, uniform film to the seal surface and bore. Excess grease can attract abrasive dust or particulate contamination during pump operation 

• Surface Preparation: Ensure all sealing surfaces, O-ring grooves, and bores are completely clean and dry before application to allow the lubricant to adhere correctly

• Full Depressurization (Critical): Always fully depressurize the waterjet system and follow lockout/tagout procedures before applying lubricant during maintenance 

• Food Safety Compliance: For food-grade applications, use only NSF H1 certified lubricants like this product. Standard greases are not permissible in food processing environments 

Storage:

• Sealed Container: Keep the lubricant container tightly sealed when not in use to prevent contamination by abrasive dust or drying out 

• Environment: Store in a clean, cool, dry environment away from direct sunlight, ozone sources, and chemicals to prevent degradation

• Clean Application: Use a clean applicator or dispensing method to avoid introducing contaminants into the lubricant container
