IWM's Portable Waterjet Cutter Machine

Portable waterjet cutting machine is also known as mobile waterjet. It can be loaded on a truck or a trailer so that the cutting can be performed at the location where the object to be cut is located. The machine mainly consists of a high pressure water jet pump, a cutting gun, and an abrasive feeder. The cutting gun is often mounted on a carrier which can move along special designed rails. In some cases, the waterjet cutting gun can be handheld for special needs. Handheld waterjet cutting requires some operator experience and also sufficient safty protection. In some cases, portable waterjet is submerged underwater to cut metal or concrete structures, such as underwater waterjet cutting of pipes or other types of applications.

The mobile waterjet machine mainly consists of a high pressure pump, abrasive feeding system and portable rails that water jet cutting head can be mounted. The portable water tank and water pump are optional.

  1. High pressure waterjet cutter pump, 250-380Mpa (40-55kpsi).
  2. Abrasive feeding sub system
  3. Rails for cutting circular shapes and straight lines. There are three types of      basic rails and handheld support rack.

Model 1 Pipe cutting rail

Model 2 Straight cutting rail

Model 3 circular cutting rail.

Model 4 handheld support rack.

Portable waterjet is commonly used to cut pipes in the filed and to cut openings for demolishing large tanks or containers.

Due to high pressure, portable water jet is not recommended to cut with bear hand held torch. The handheld cutting gun is better to be supported with a stand rack. In most cases, the cutting head is mounted on a motor driven carrier moving along the rails for constant speed and steady move. The speed is adjustable in order to fit the need of cutting different types of materials and different thickness.

CNC controlled portable waterjet is also available. This type of portable waterjet is specialized cutting holes that can be use to connect branches to the main pipe.

Underwater cutting with portable waterjet machine

In the case of underwater portable waterjet cutting, the small car that carries cutting head is driven by a hydraulic motor. A hydraulic prower station is needed. Abrasive and water is pre-mixed in a pressure vessel, and a high pressure jet of water brings in the mixture and shoot through the nozzle to make cuts. The water pump and vessel remain above water. The cutting rail and car go underwater and driven by hydraulic power. The portable underwater waterjet cutting machine can cut metal, concrete and other types of materials.
