Plunger pump 4000

waterwith electric motorstationary

Overview
Experience the next generation of waterjet power with the stand-alone Direct Servo Drive 4000 Pump engineered for OEM waterjet systems. Delivers the same cutting speed and thrust as a hydraulic intensifier while reducing electrical consumption up to 50%. Runs continuous, pulsation-free up to 4000 bar (58,000 psi) with whisper-quiet operation, low maintenance and extended service intervals.

Key benefits

• Up to 50% lower electrical energy consumption compared to hydraulic intensifiers.
• Whisper-quiet operation with near-silent servo motor design (no hydraulic shock or high-decibel clatter).
• Continuous duty at 4000 bar for 24/7 operation without heat-soak or duty-cycle limits.
• Precision flow control with ±0.5% repeatability for consistent kerf and edge quality.
• Small footprint and OEM-ready electronics for easy machine integration.
• Built-in diagnostics including real-time pressure, temperature and vibration monitoring; supports remote firmware updates.

Operational highlights

• Adaptive flow tuning: intelligent servo control continuously adjusts pressure and water flow in real time to maximize abrasive efficiency and surface finish across a wide range of materials.
• Pulsation-free flow delivers smoother, more consistent cuts and optimized abrasive usage.
• Designed for OEM integration with embedded control interfaces (EtherCAT, Modbus TCP/IP and analog/digital I/O) for plug-and-play connection to existing controllers or PLCs.

Key Features

• Up to 50% lower energy draw while maintaining equivalent cutting performance to intensifiers.
• Ultra-quiet operation due to direct-servo architecture.
• Continuous-duty capability at 4000 bar (58,000 psi).
• Precision flow control: ±0.5% repeatability.
• Industrial-grade construction: martensitic stainless steel components, ceramic plungers and PEEK seals designed for abrasive waterjet environments.
• OEM-ready electronics and communications: EtherCAT, Modbus TCP/IP, analog/digital I/O.
• Built-in diagnostics for proactive maintenance and uptime maximization.
