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 portable water jet cutting gun can be handheld for special needs. Handheld waterjet cutting requires some operator experience and also sufficient safty protection. Portable water jet cuter price is less than a full CNC waterjet cutting machine. 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 where water jet cutting head are mounted on. A portable water tank and a water pressure boost 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 water jet cutter is commonly used to cut pipes in the filed where the pipes are installed and another popular application is to cut openings for demolishing large tanks or containers.

Portable straight rails can be mounted on the roof or vertical wall of a tank for cutting holes or straight lines. With staight lines, it can form triangle, rectangle or other polygon shapes of openings.

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 various thickness. However, in some special cases, the cutting head on the rail can not reach the location where we want to cut. So it is desiable to use handheld porable waterjet cutting. Due to high pressure, it is not recommended to hold the portable waterjet cutting gun just by bear hands. The handheld cutting gun is better to be supported with some kind of stand or rack.

The above two pictures demonstrates handheld mobile waterjet cutting machine cuts off a rusted bolt held. The cutting gun is hand held and supported by a simple stand.

Other than just cut around the pipe, we often need to open holes on the wall of pipes or tanks for repair jobs or add branches. There are two types of portable waterjet machine we can choose from, with or without CNC control. If we just want to cut circular holes, we can use the non-CNC type of the machine shown as blow. portable waterjet cuts hole on pipe

CNC controlled portable waterjet is also available from IWM. This type of portable waterjet is specialized in 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 shoots through a nozzle to make cuts. The water pump and vessel remain above water. The cutting rail and car go underwater and driven by hydraulic power. There is specially designed hose that connects the pump to vessel and vessel to the cutting nozzle on the car. The portable underwater water jet cutting machine can cut metal, concrete and other types of materials. Please contact us for more details.
