In the world of chemical manufacturing, the challenge of efficiently moving thick, sticky, or paste-like materials can be a major headache. Whether you're dealing with adhesives, heavy oils, or high-solids content slurries, traditional pumping methods often fall short—resulting in wasteful material loss, frustrating flow inconsistencies, or even complete system failures. That's where Graco's Check-Mate pumps come in, offering a game-changing approach to handling high-viscosity chemicals with remarkable efficiency.

The Viscosity Challenge in Chemical Manufacturing

Moving highly viscous materials presents several unique obstacles that standard pumps simply weren't designed to handle:

• Flow resistance increases exponentially with viscosity
• Cavitation occurs when standard pumps create vacuum pockets
• Material shearing can alter critical chemical properties
• Pump stalling happens when motors can't overcome material resistance
• Incomplete container evacuation leads to costly material waste

The consequences? Production delays, compromised product quality, excessive material waste, and inflated operational costs that directly impact your bottom line.

Traditional Transfer Methods: Why They Fall Short

Conventional pumping technologies often struggle with high-viscosity materials for several reasons:

Centrifugal Pumps

These velocity-dependent pumps create fast-moving fluid streams that work well for water-like substances but lose efficiency dramatically as viscosity increases. When handling thick materials, they:

• Consume excessive energy
• Generate unwanted heat that can affect chemical properties
• Deliver inconsistent flow rates
• Often fail to self-prime with viscous materials

Gear Pumps

While better suited for thickness than centrifugal options, gear pumps have their own limitations:

• Metal-on-metal contact creates wear points
• Tight tolerances make them susceptible to abrasive particles
• Limited ability to handle entrained air
• Difficulty managing varying viscosities

Pneumatic Diaphragm Pumps

Though versatile, standard diaphragm pumps often lack:

• Sufficient pressure capability for truly thick materials
• Efficient air consumption at higher pressures
• Steady, pulse-free flow needed for precise applications
• Effective self-priming ability with extremely viscous materials

Introducing Graco's Check-Mate Pumps: Engineered for Extreme Viscosity

Graco's Check-Mate pumps represent a purpose-built solution for the toughest material transfer challenges. These high-pressure, high-volume displacement pumps operate on a fundamentally different principle than conventional technologies—one that excels specifically with high-viscosity materials.

Key Features That Make the Difference

1. Powerful Displacement Design

The Check-Mate's reciprocating piston design creates positive displacement that literally "pushes" material through the system rather than trying to "pull" it like many traditional pumps. This fundamental difference allows it to:

• Generate pressures up to 6,000 PSI (414 bar)
• Move materials with viscosities exceeding 1,000,000 cPs
• Maintain consistent output regardless of back pressure

2. Advanced Priming Capability

Check-Mate pumps feature:

• Large intake valves that facilitate material flow into the pump chamber
• Long stroke design that creates sufficient vacuum for self-priming
• Priming piston configurations for especially challenging materials

3. Superior Sealing Technology

Handling high-viscosity chemicals demands exceptional sealing, which Check-Mate delivers through:

• Long-lasting throat packings designed for abrasive materials
• Adjustable packing tension for optimal sealing and longevity
• Quick-replacement cartridge designs that minimize maintenance downtime

4. Versatile Material Compatibility

Chemical compatibility concerns are addressed through multiple construction options:

• Stainless steel fluid sections for corrosive environments
• Carbon steel versions for non-corrosive applications
• Various seal material options including PTFE, UHMWPE, and specialty elastomers

The Benefits: Measurable Advantages Over Traditional Methods

Implementing Graco Check-Mate pumps in your chemical manufacturing process delivers several quantifiable benefits:

1. Near-Complete Material Evacuation

Check-Mate pumps can recover up to 99% of material from containers, compared to the 85-90% typical with traditional methods. For expensive specialty chemicals or adhesives, this difference translates directly to thousands in saved material costs annually.

2. Reduced Labor and Maintenance Costs

The robust design requires less frequent maintenance than gear pumps or progressive cavity pumps, with:

• Easily serviceable wet cups that extend seal life
• Quick-disconnect lower pumps for fast service
• Fewer moving parts than complex alternative systems

3. Consistent Material Properties

Unlike high-shear pump designs that can alter material characteristics, Check-Mate pumps maintain chemical integrity through:

• Low-shear material transfer
• Minimal heat generation
• Gentle handling of shear-sensitive formulations

4. Improved Production Efficiency

Manufacturing operations benefit from:

• Faster material transfer rates
• Reduced downtime for drum or tote changes
• Consistent supply pressure for downstream processes
• Ability to pump directly from original shipping containers

Applications in Chemical Manufacturing

Check-Mate pumps excel in numerous chemical manufacturing scenarios:

• Adhesive Production: Transferring base polymers and finished adhesives with viscosities exceeding 500,000 cPs
• Sealant Manufacturing: Moving high-solids silicones and polyurethanes without separation
• Resin Systems: Handling epoxies and other reactive components with consistent proportions
• Lubricant Production: Transferring heavy greases and specialty lubricants
• Specialized Coatings: Moving high-solids content protective coatings while maintaining formulation integrity

Integration With Complete Material Handling Systems

Graco's Check-Mate pumps don't operate in isolation—they form the heart of comprehensive material handling systems that can include:

• Ram packages for following plates to prevent material cavitation
• Heated pressure plates for temperature-sensitive materials
• Automated controls for precise pressure and flow management
• Level sensors for seamless container changeover
• Multiple-pump configurations for large-volume applications
