705-40-01020 Hydraulic Variable Vane Pump FAQ

1. What are 705-40-01020 gear pumps

The 705-40-01020 is a high-performance external gear pump specifically designed for Komatsu equipment. It is widely recognized as the standard hydraulic pump for small-to-medium excavators (such as the PC60 and PC70 series), serving as a reliable source of power for the machine’s working attachments and control systems.

2. Is the 705-40-01020 compatible with my Komatsu machine?

3. What is the working pressure range of 705-40-01020 pumps

As a heavy-duty construction grade pump, it is designed to operate at a rated pressure of approximately 20.6 MPa (210 bar). It is built to withstand the high-pressure pulsations common in excavation and earthmoving tasks, ensuring consistent performance under heavy loads.

4. Can 705-40-01020 pumps replace other brands

5. What hydraulic oil is suitable for 705-40-01020 gear pumps

• High-quality mineral-based hydraulic oil (ISO VG32, VG46, or VG68 depending on ambient temperature).

• Anti-wear (AW) hydraulic fluids (ISO HM / DIN HLP).
  Maintaining oil cleanliness (ISO 18/15 or better) is critical for preventing gear wear.

6. What is the typical speed range of 705-40-01020 pumps

To maximize the service life of the gears and bearings, we recommend:

• High-quality mineral-based hydraulic oil: ISO VG46 or VG68 are standard for construction environments.

• Anti-wear (AW) additives: Essential for protecting the precision-engineered gear teeth.

• Filtration: Keeping the oil clean (ISO 18/15 or better) is the most effective way to prevent premature wear and pump failure.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
