In this Shop Talk Blog post, were are going to take a look at the Eaton JPVB back-to-back axial piston hydraulic pumps. These pumps are very well adapted for use in excavators, and can serve as quality aftermarket replacements for OEM hydraulic pumps (depending on the make and model of the machine). Keep reading to learn about what the Eaton JPVB hydraulic pump has to offer, including technical specifications and key benefits.
Eaton Pumps
Being a leader in power technology, it should come as no surprise that Eaton has an vast range of hydraulic power equipment, including pumps, hydraulic drive motors, valves, fittings, filters, and hydraulic lines. Along these lines, Eaton offers one of the widest portfolios of hydraulic pumps that includes external gear pumps, open circuit piston pumps, closed circuit piston pumps, and vane pumps. Their line of pumps includes both industrial and mobile pumps.
The Eaton JPVB Pump
The Eaton JPVB is a open circuit axial piston main pump with a back to back design. The term "back to back" means their rotating kits are facing each other and share the same center manifold. They work as a single unit and cannot be separated. Part of the key design goals for the JPVB pump were to provide low noise, high efficiency, and very accurate control. Also mote that the JPVB pump works well on 20- to 25-ton hydraulic excavators as well as crawler cranes.
Technical Details for the Eaton JPVB Pump
Here are some of its more specific hydraulic specifications:
- Displacement: 112cc/r X2
- Continuous pressure: 345 bar
- Peak pressure: 390 bar
- Rated pressure: 350 bar
- Rated speed: 2360 rpm
- Maximum speed: 2460 rpm
- Minimum speed: 600 rpm
- Power: 125 kw (168 hp)
Total horsepower (hp) is maintained by adjusting the horsepower of one pump based on the delivery pressure of another pump, made possible by the back to back design. Variable horsepower control is also possible. It also has negative flow control and cross power control while including power summation controlled by an electro-hydraulic proportional valve. Due to its design, this axial piston hydraulic pump has the flexibility to be configured in a positive flow control arrangement for other applications or alternative excavator models.
Benefits of the Eaton JPVB Hydraulic Pump
Some of the most prominent benefits of this pump include:
- High efficiency
- Fast response and recovery
- Low fluctuations
- Low noise
- Low hysteresis
- Accurate horsepower control
Finally, this Eaton hydraulic pump provides excellent overall performance and reliability at a competitive price.
Hydraulic Pumps
The Eaton JPVB back to back open circuit axial piston pump is an excellent option to consider if you need a replacement pump for a 20 to 25 ton excavator. It offers excellent efficiency, accurate control, outstanding performance, and proven reliability. Don't forget to consider Eaton hydraulic motors and pumps as an option when you need a quality aftermarket replacement.
