Product Description

Nachi Type VUP & VDN Series High-Performance Variable Vane Pumps

Product Overview: The VUP and VDN Series variable displacement vane pumps are the precision core of advanced hydraulic power systems. Engineered as premium Pressure Compensated units, these pumps instantaneously adjust displacement to meet load demands. This featured range includes the compact VUP-16, high-flow VUP-23, and versatile combinations such as VDN-1B-0A4/UVN-1A and VDN-1B-1A3-U-6179B. Renowned for their ultra-quiet operation and rapid dynamic response, these pumps significantly lower energy consumption and inhibit hydraulic oil temperature rise, making them the ideal choice for modern industrial automation.

Key Technical Advantages:

  • Precision Variable Energy Saving: Equipped with high-sensitivity pressure regulators. When preset pressure is reached, displacement drops to minimum, eliminating overflow heat and drastically reducing electrical costs.

  • Ultimate Silent Operation: Utilizing a specialized silencing design for the stator and vane structure, ensuring noise levels remain at industry-leading low decibels even under full pressure-holding states.

  • High Reliability & Long Life: Core components undergo precision heat treatment and grinding, offering exceptional wear resistance for long-term stability in high-frequency CNC machine cycles.

  • Flexible Combination Solutions: The VDN-1B series easily integrates with UVN pumps, providing multiple independent flows from a single drive shaft.

  • Target Applications: CNC cutting machines, specialized grinders, small injection molding auxiliary circuits, spindle lubrication systems, and energy-saving industrial Hydraulic Power Units (HPU).

Detailed Models & Parameters:

  • Core Series: Nachi Type VUP, VDN, UVN Series (Variable Displacement).

  • Model Keywords: VUP-16, VUP-23, VDN-1B-0A4/UVN-1A, VDN-1B-0A2-6231B, VDN-1B-1A3-U-6179B.
