Triplex Design for Efficiency and Longevity
The triplex plunger design of the TT2035EBF ensures smoother operation, reduced vibration, and longer service life compared to axial pumps. With three high-strength ceramic plungers, the pump is engineered to withstand abrasion, heat, and extended use.
Producing 2,000 PSI at 3.5 GPM, this pump offers an excellent balance of moderate pressure and high flow. The higher gallon-per-minute rating makes it ideal for cleaning large areas quickly, rinsing debris efficiently, and tackling applications where water volume is just as important as pressure.
The brass manifold ensures durability against corrosion and pressure fatigue, while the precision design of General Pump components ensures dependable performance year after year.
User-Friendly Features
The TT2035EBF is equipped with features that enhance convenience and versatility:
External unloader (85.300.003): Provides precise control over system pressure and makes servicing or replacing the unloader simple.
Adjustable soap injector (85.400.000): Allows operators to fine-tune detergent application. Just switch to a low-pressure nozzle to draw soap into the water stream.
Brass quick-connect discharge (3/8”): Ensures fast, secure hose connections that resist leaks and simplify setup.
These features make the pump versatile enough for residential and professional operators who need reliability and ease of use.
Protection and Maintenance
The pump includes a thermal relief valve (85.300.023), which automatically releases overheated water during extended bypass, protecting seals and internal components from heat damage.
It requires 11.2 oz of 30W non-detergent oil for proper lubrication. Regular oil checks and scheduled oil changes are easy, low-cost maintenance tasks that extend pump life.
With a maximum inlet water temperature of 165°F (74°C), this pump offers more tolerance than most models, making it ideal for applications where warmer water may be used.
At 11.5 lbs, the pump combines rugged durability with manageable weight, ensuring easy installation and dependable operation.
