The Century solves a range of hydro-jetting and blasting challenges. With the variable pressure and flow capabilities of the Harben Century pump, operators can adjust the machine's output from 10,000 psi at 14 gpm to 2,000 psi at 23.5 gpm. Other pressure and flow combinations are available to provide flow rates up to 32 gpm.

The advanced radial piston diaphragm design of the Century pump achieves several distinguishing capabilities:

  • Operate with fresh, reclaimed and salt water as well as well as many chemical and petro-chemical solvents.
  • No moving parts to corrode, wear or fatigue.
  • Run dry indefinitely without water
  • Achieve constant pressure and flow without the need for accumulators to dampen pulsation
  • Long term reliability. Run the Century pump for thousands of hours without a major overhaul

Power the Century pump with an electric motor or industrial class diesel engine. Configure the Century as a skid, trailer or truck mounted machine.

The Century pump has proven its value in a diverse range of applications:

  • Tube and tank cleaning for refining, beverage processing and distilling operations
  • Removal of tuberculation, lime and calcium deposits from underground sewer, water and drain pipes
  • Hydro-excavation through bedrock
  • Steel billet descaling and deburring of cast ceramic and metal parts
  • Concrete and steel surface cleaning: rubber removal from airport runways; road surface texturing; paint and rust removal; hull reconditioning in shipyard repair facilities
