FAQ Section

How does the Hydraulic Gear Pump K3V112 handle 320 Bar peak pressure in mining?

Answer: The dual-stage helical gears distribute load across 4 contact points, while the nitrided surface (0.15mm layer, HV 1100) reduces micropitting. Each pump undergoes 1,000 pressure cycles (0-320 Bar) to validate structural integrity.

Can the Hydraulic Gear Pump K3V112 be configured for simultaneous boom/swing operations?

Answer: Yes. Select dual-circuit mode (A/B ports) with priority flow control. Custom logic valves can allocate 70% flow to boom and 30% to swing via CAN bus programming.

How to diagnose cavitation in the Hydraulic Gear Pump K3V112 system?

Answer: Use DOOSAN’s D-ECU diagnostic tool to monitor suction pressure (>-0.2 Bar) and fluid temperature (<75°C). High-frequency vibration analysis (>5kHz) pinpoints early cavitation zones.

How to optimize the Hydraulic Gear Pump K3V112 for fuel efficiency?

Answer: Enable ECO mode via DOOSAN’s DPLS software, reducing idle flow to 5 L/min. Pair with variable displacement motors for up to 30% fuel savings in grading operations.
