An intensifier pump uses hydraulic force to pressurize water for the cutting head. Understanding the pressure path helps distinguish a pump specification from the conditions of a particular cut, and a visible symptom from its underlying cause.
How hydraulic force becomes water pressure
An electric motor drives the hydraulic pump. Pressurized oil acts on a hydraulic piston connected to a smaller water ceramic plunger. The difference in effective area allows the ceramic plunger to generate water pressure above the hydraulic pressure acting on the hydraulic piston. Check valves control the direction of water flow through the high-pressure section.
The cutting head then converts that pressurized water into a jet at the orifice. In an abrasive cutting head, abrasive joins the stream and passes through the mixing tube. The pump generates pressure; the head forms the cutting stream. Both belong in the system assessment.
Read continuous pressure alongside maximum operating pressure
Continuous pressure describes sustained operating pressure. Maximum operating pressure is a separate rating and should remain separately labeled when comparing pump specifications.
VICHOR's current product specification lists these figures:
| Pump | Continuous operating pressure | Maximum operating pressure |
|---|---|---|
| WCM-P60IV | 380–400 MPa | 430 MPa |
| WCM-P90III | 540–560 MPa | 600 MPa |
These are pump specifications, not cutting-speed or finished-part guarantees. Head configuration, material and the required edge condition must be specified for the job.
What to compare when choosing a configuration
Start with the material, thickness and planned workload. Ask which operating pressure and cutting-head arrangement the proposed configuration uses. Keep the pressure rating, the expected cutting result and the maintenance plan as distinct parts of the discussion.
Service access and consumable parts planning also matter. VICHOR's WCM-P60IVB uses an active intensifier and a standby intensifier with independent hydraulic circuits. Its arrangement allows scheduled seal and hydraulic piston maintenance on the idle unit while the other maintains cutting.
Treat a symptom as a starting point
When pressure or cutting performance changes, record the displayed readings, alarms, operating state and when the change occurs. Keep the pump configuration and recent maintenance history with that record. A rough cut alone does not establish a pump fault: cutting-head condition, abrasive delivery and the selected cutting settings are also relevant to the stream and finished edge.
Follow the equipment's maintenance instructions and use qualified service support for high-pressure components.
