Specifications

Triplex Advantage

Unlike axial-cam pumps, the triplex plunger design uses three ceramic plungers to deliver smoother pressure output, reduced vibration, and significantly longer service life. This makes the TT2035EBF ideal for applications that require extended run times and consistent performance.

With 2,000 PSI, the pump provides safe, effective cleaning pressure for surfaces and equipment, while 3.5 GPM ensures fast rinsing and efficient debris removal—perfect for users who prioritize flow over extreme pressure.

Built for Durability

The TT2035EBF is engineered for longevity in electric pressure washer systems:

• Ceramic plungers resist heat, wear, and abrasion

• Brass manifold protects internal components from corrosion

• 3/4" shaft ensures compatibility with many electric motor setups

• Compact 11.5-lb design balances strength with easy handling

These features make it a dependable replacement pump for professional electric units.

Operator Convenience & Protection

Designed with serviceability and safety in mind:

• External unloader (85.300.003) for easy pressure tuning and replacement

• Adjustable soap injector (85.400.000) for controlled detergent application

• Brass quick-connect discharge for secure, leak-free hose attachment

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

This configuration reduces downtime and protects internal components from heat damage.

Maintenance & Service

Routine maintenance is simple and cost-effective:

• Requires 11.2 oz of 30W non-detergent oil

• Easy oil checks and changes extend pump life

• Rated for inlet water temperatures up to 165°F (74°C)

With proper maintenance, the TT2035EBF delivers consistent, long-term performance.
