Two-Stage Flexibility with High Performance
Combines compact size and light weight with 2-stage high performance. Designed for operating pressures up to 10,000 PSI. Vanguard Jr. gives you just what you need: 2-stage flexibility with high performance and a selection of units and options that lets you tailor the pump to your needs. Refer to the performance and speed tables below and you’ll see how these pumps cut down on the time needed for almost any job.
The 2-stage operation automatically matches pump performance to the job requirements. The low-pressure, high-volume stage provides fast ram approach and return. Then at approximately 200 PSI, the high-pressure, low-volume stage takes over to handle high force requirements.
This pump is ideal for hundreds of hydraulic applications such as clamping, bending, straightening, pressing, forming, testing, pushing, and pulling. Equipped with a relief valve factory-set at 10,000 PSI (the maximum operating pressure of the pump).
Vanguard Jr. starts easily under load and has been thoroughly field-tested for high cycle reliability.
