Description

Built for the Toughest Jobs

The TSP1621 Triplex Plunger Pump is the real deal - designed from the ground up for the most extreme-duty industrial cleaning jobs out there. This pump is a beast among high pressure pumps , capable of producing an astonishing 6,525 PSI of pressure combined with an impressive 4.3 GPM flow rate. That makes it a perfect fit for jobs that demand maximum force, such as roughing up concrete for demolition prep, blasting away thick paint and rust, or doing brutal washdowns in marine, mining, and heavy manufacturing environments.

This thing is built to last, running on a robust, slow-speed design that operates at a mere 1,450 RPM. That slower speed is a game-changer, because it cuts down on wear and tear on the internal components, allowing it to handle continuous 24/7 operation with ease. And with its ability to adapt based on drive type, whether belt-driven or gearbox-driven, it's super versatile - you can hook it up to just about any high-horsepower electric motor or gas/diesel engine. Its 41lb weight is a testament to its heavy-duty construction and the reinforced parts needed to handle that kind of extreme pressure.

What You Get and Why It Rocks

So what sets the TSP1621 apart? For starters, it can handle pressures that most commercial pumps can only dream of. That's due to some serious Italian engineering and top-of-the-line materials, including a beefy manifold that can take the cyclical stress of over 6,500 PSI.

  • Efficiency and Power: This thing packs some serious punch, with a brake horsepower (BHP) requirement of 19.5 and a hydraulic power factor (GHP) of 25. That means it can handle some of the toughest hydro-blasting and surface prep jobs out there.\

  • Slow-Speed Longevity: Unlike those high-speed direct-drive pumps that burn out in no time, the 1,450 RPM operation of the TSP1621 means it lasts you a long, long time. Fewer cycles per minute, less heat generation, reduced friction - all of that adds up to less maintenance and lower overall costs in the long run.

Getting It Installed and Up and Running

The TSP1621 is a bit of a beast, so it's not a DIY job. Installation requires expert knowledge and a bit of finesse - proper alignment and secure mounting via the pump's solid base, typically using a belt-and-pulley system or reduction gearbox driven by a high-horsepower power source. The solid 24mm shaft provides a robust coupling point, capable of handling the high torque required to drive the pump.

Reliability is key at these extreme pressure levels, and the TSP1621 delivers on that. Its slow-speed operation is the secret to its longevity, ensuring continuous, dependable performance in the harshest environments. For applications where a pressure washer pump failure is costly and time-consuming, the heavy-duty construction, robust bearings, and high-quality seals of the TSP1621 give you a level of confidence and operational uptime you just can't find anywhere else.
