Features
Dual-motor driven gear pump ensures smooth operation, low noise, strong self-priming, and stable performance.
High-pressure piping is equipped with overflow protection to prevent overpressure operation.
Thermal relay protection prevents motor overload and damage.
Suction inlet equipped with a coarse filter protects the pump and extends the life of precision filters.
Two-stage precision filtration rapidly improves oil cleanliness.
Filter precision is selectable to meet different operating conditions.
Integrated panel pressure gauges allow real-time monitoring of system status and filter contamination.
