Professional Triplex Pump Design
At the heart of the TS2021 is its triplex plunger design, which provides smooth, efficient, and reliable operation. The use of three ceramic plungers enhances durability by resisting heat and wear, helping to extend seal life and reduce maintenance costs over time.
With a flow capacity of 5.6 gallons per minute, the TS2021 excels at jobs that require covering large areas quickly without sacrificing cleaning pressure. Its maximum 3,500 PSI rating ensures that it has the muscle to cut through dirt, grease, and debris, making it suitable for everything from industrial machinery washdowns to large-scale surface preparation.
Built to Last
Durability and longevity are central to the TS2021’s design:
Nickel-plated brass manifold offers superior corrosion resistance and excellent heat dissipation, making it ideal for professional use.
Ceramic plungers withstand high temperatures and abrasion for extended service life.
Belt-drive system reduces pump speed to just 1,450 RPM, lowering wear and extending the lifespan of internal components.
Stainless steel quick-connect discharge (85.300.108S) ensures strong, leak-free connections under high pressure.
At 32 lbs, this pump offers a solid, durable build that can withstand tough daily use in demanding applications.
Operator-Friendly Features
The TS2021 includes features that make operation safer and more efficient:
External unloader (AL607): Provides precise control of output pressure and simplifies servicing.
Adjustable soap injector (optional, 85.400.000): Allows controlled detergent application for better cleaning results.
Thermal relief valve (85.300.023): Protects the pump from overheating during bypass conditions.
Stainless steel discharge connection: Provides secure, rust-resistant durability for high-pressure hose attachment.
These details make the TS2021 easier to use and maintain, reducing downtime and improving reliability on the job.
Low-RPM Advantage
Unlike direct-drive pumps, the belt-drive design of the TS2021 allows it to ope
