Specifications

Triplex Pump Performance You Can Rely On

The TS2021’s triplex plunger design provides smooth, efficient water delivery with reduced pulsation compared to axial pumps. Its ceramic plungers resist heat and wear, extending seal life and minimizing downtime under continuous operation.

With 5.6 GPM, this pump is ideal for applications that require efficient rinsing and broad surface coverage, while 3,500 PSI ensures enough pressure to remove grease, grime, and stubborn buildup.

Built for Long-Term Professional Use

• Nickel-plated brass manifold for superior corrosion resistance

• Ceramic plungers to withstand high temperatures and heavy use

• 1,450 RPM belt-drive operation to reduce internal stress

• Stainless steel QC discharge for rust-free, leak-free hose connections

At 32 lbs, the TS2021 delivers a solid, durable build without unnecessary bulk—ideal for commercial belt-drive systems.

Operator-Focused Design

• External AL607 unloader for precise pressure control and easy servicing

• Optional adjustable soap injector for controlled detergent application

• Thermal relief valve (85.300.023) protects the pump during bypass operation

• Stainless steel discharge fitting for long-term durability in wet environments

Low-RPM Advantage

Operating at 1,450 RPM, the TS2021 runs cooler and quieter than direct-drive pumps. This significantly extends seal, bearing, and plunger life—making it an excellent choice for systems that run longer cycles or daily workloads.

The pump is also rated for inlet water temperatures up to 165°F (74°C), supporting hot-water applications for enhanced cleaning performance.
