Main advantages and scope of application of Nachi PHV series hydraulic motors

Nachi PHV series hydraulic travel motors (side gearboxes) are one of the most popular solutions for mobile equipment, in particular for mini excavators. Their advantages are due to advanced engineering solutions and high production quality.

Main advantages of Nachi PVD series hydraulic motors:

1. Integrated "All-in-one" design:
   • This is the key advantage of the series. All the necessary components are combined in one compact housing:
     • Axial piston hydraulic motor.
     • Planetary gearbox to increase torque.
     • Automatic disc parking brake.
     • Valve block (safety, anti-cavitation, etc.).
     • This simplifies installation, reduces the number of external hydraulic lines, and increases overall system reliability.
2. High power in a compact size:
   • Thanks to their integrated design, PHV motors have a high power density. They produce significant torque while taking up minimal space, which is critical for today's compact special equipment.
3. 2-Speed Function:
   • The PHV series is standard equipped with the ability to switch between two operating modes. This allows the operator to choose:
     • Low speed: for maximum traction during operation.
     • High speed: for quickly moving the machine around the work site.
4. High efficiency and reliability:
   • The axial piston design ensures high efficiency even when operating under high pressure. This reduces energy loss and engine load. Japanese Nachi quality guarantees long service life and trouble-free operation in difficult conditions.
5. Smooth operation and safety:
   • The motors are equipped with special valves that ensure smooth start and stop, preventing jerks and hydraulic shocks. The built-in automatic parking brake reliably fixes the machine when stopped, which is an important safety element.
6. OEM quality and compatibility:
   • Nachi is an Original Equipment Manufacturer (OEM) supplier to many leading excavator manufacturers (e.g. Bobcat, Komatsu, Kubota). This means that the PHV motors are designed to be perfectly compatible with the hydraulic systems of these machines and meet the highest factory standards.
