The iP55-280DS intensifier features Jet Edge's reliable tie-rod design and an attenuator to smooth pressure fluctuations.

The iP55-280DS is powered by a dependable 280hp Cummins diesel engine.

The iP55-280DS features an in-line quad water filter.

55,000 psi (4100 bar) Continuous Operating Pressure
280 hp, 4.3 gpm (16 lpm) Maximum Flow Rate

Experienced waterjet contractors prefer Jet Edge hydraulic waterjet intensifier pumps.

Here’s why:

  • Reliable Tie-Rod Design eliminates threads on the high pressure cylinders, end caps, and hydraulic cylinders. This reduces the likelihood of cracking and increases component life.

  • Matched metal components prevent galling of hydraulic components. Intensifier designs allow for the usage of common tools instead of specialized jacking system tools. Hydraulic accumulators are standard on all pumps. This provides smoother hydraulic pressure, reduces spikes and prolongs hydraulic pump life.

  • Hydraulic fluid is cooled and filtered.

  • Rugged hydraulic center section incorporates high duty cycle-rated piston seal and wear rings.

  • Easy Maintenance - Intensifier components can be accessed without having to get into the hydraulic center section and hydraulic rod seal.

  • Leak detection block indicates seals needing replacement. (optional on some pumps).

  • No special tools required.

  • CE-marked attenuator smoothes pressure fluctuations and delivers constant and steady stream of UHP water.

  • On-board water filtration protects pump components, maximizing machine run time.
