Review on πͺ Enhanced Performance: OTC 4020 Air Hydraulic Pump - Next-Level Efficiency and Power by Brett Morrison
Worked in hydraulics, pneumatics and plumbing for a while
We used this as a pump replacement for a 30 ton press. It worked well initially, reaching 10,000 psi. After a few hundred cycles at 8000psi, problems began to reach full pressure. Now you can only get 7500 psi which is not enough for use. According to our observations, it probably needs to be rebuilt. We think this is an excellent device for applications that don't require medium to high performance.
- Handy item
- So far so good
