Case at a glance · Canada
A Canadian metal fabrication shop upgraded from a continuously running induction-motor pump to Yuanhong's H2O servo intensifier pump to reduce wasted energy, heat and operating noise.
01 · The Challenge
The High Cost of Wasted Energy
The customer operated a traditional waterjet cutting machine driven by a standard induction motor. As local electricity rates rose, operating costs increased sharply.
The pump continued running at full speed during material loading and cutting-head repositioning. Unused pressure became waste heat, increasing both electricity consumption and cooling demand.
02 · The Science
Servo Motor vs. Standard Motor in Waterjet Systems
A conventional AC motor operates at a fixed maximum speed whenever it is switched on. When the cutting head closes, the pump still produces pressure and bypasses the unused energy through a relief circuit.
Standard Induction Motor
Runs continuously at fixed speed, including pauses. Bypassed hydraulic energy becomes excess heat and adds load to the cooling system.
Responsive Servo Motor
Adjusts motor speed to real-time pressure demand. It accelerates as the nozzle opens and slows to near-stop when cutting pauses.
03 · The Solution
The Yuanhong H2O Servo Motor Intensifier Pump
Yuanhong upgraded the customer's pressure system with an intelligent servo-driven intensifier pump engineered to deliver pressure only when the cutting process requires it.
Up to 60% Energy Savings
Demand-based motor control reduces power consumption during loading, repositioning and other non-cutting periods.
Lower Cooling Demand
Less bypassed hydraulic energy means lower oil temperature, reduced heat-exchanger load and lower cooling-water use.
Quieter Operation
The pump slows during idle periods, reducing workshop noise and creating a more comfortable environment for operators.
Precise Pressure Control
Responsive servo regulation minimizes pressure spikes and supports consistent cutting performance and edge quality.

05 · The Impact
Lower Utility Demand and a Quieter Workshop
The upgrade reduced electricity and cooling demand while improving the acoustic environment around the production line. Responsive pressure control also gave the customer a more efficient foundation for ongoing waterjet operation.
