Air-Over-Oil Hydraulic Power Unit Retrofit

Performance was so poor that the client was actually needing to replace the pump every 90 days or 4x/year. Not only did they incur $6000 per year in replacement part costs but, the leaking of the press resulted in poor cake quality. This drove longer cycle times and greatly increased the time needed to clean the press between cycles. Plus, the poorer quality cake increased the company’s waste disposal costs.

Micronics has considerable expertise in optimizing filter press parts performance to maximize press efficiency and up-time so we knew we could provide a robust, cost-effective solution.

The Micronics Solution

It isn’t always a complex, expensive solution! It is often deep expertise based on years of field experience that allows the Micronics team to troubleshoot, both physically on-site and often over the phone. This is definitely worthy of consideration in these times of COVID lingering, new strains, and minimizing travel.

Via the telephone, Micronics personnel – working with onsite customer personnel – conducted several troubleshooting tests. Based on this troubleshooting & problem identification, we were able to determine that the seals in the customer’s hydraulic ram were allowing fluid to “bleed” by, and this was ultimately the cause for the lack of pressure and the continuation of the intensifying pump cycling.

Since this was an 800mm, 15 chamber filter press, we were able to evaluate that the return on investment associated with replacing the ram would in fact be greater than the return associated with rebuilding the existing older unit.

The customer elected to replace his existing Air-Over-Oil HPU with a Micronics unit. In fact, Micronics personnel designed a replacement HPU and assisted with the installation including the installation of a new ram.

Results Achieved

With the implementation of the Micronics-designed Air-over-Oil HPU, the customer could now achieve proper clamping pressure, thus allowing the intensifying pump to work as designed and not continually. With the Micronics Air-Over-Oil HPU Retrofit, proper cake formation could now take place and waste disposal costs could be decreased. The customer is very happy with Micronics’ Air-Over-Oil HPU Retrofit Solution.
