How It Works

• Triplex plunger design uses three ceramic plungers to deliver a smooth, pulsation-free
  flow, improving cleaning consistency and operator comfort.
• The F24 flange and 1-inch hollow keyway shaft permit direct mounting to gas or
  diesel engines, ensuring efficient power transfer and secure torque transmission.
• Operating at 3400 RPM, the pump is tuned for high-output cleaning where speed
  and productivity are priorities.
• Ceramic plungers reduce friction and heat, extending seal life, while stainless valves maintain
  accurate flow control at working pressure.
• The nickel-plated head and robust internal components allow the pump to withstand frequent,
  heavy-duty use in challenging environments.

• Direct engine mounting: F24 flange and hollow shaft simplify installation on
  most gas and diesel power units.
• Long service life: Ceramic plungers, stainless valves, and nickel-plated head
  are engineered for durability.
• Fast cleaning cycles: 3400 RPM operation supports rapid job completion on large
  surfaces and heavy equipment.
• Easy maintenance: Vented dipstick and oil sight glass make routine servicing
  quick and straightforward.
• Reliable investment: 5-year warranty provides peace of mind in continuous-duty
  applications.

Typical Applications
