Service Details

Our engineers have designed the new 515 pump/motor module to be a direct replacement of your old 505 module. We handle everything. An MTS field service engineer will visit your site and perform the exchange, usually within 1 business day. We can even take care of the recycling/disposal of your old 505 module.

Optimize Replacement Schedule


The SilentFlo 515 Enhanced Module Replacement was engineered to work seamlessly with multi-bay HPUs that have both legacy 505 modules and new 515 modules, so you have the option of replacing each of the modules within the HPU on a regular rotating schedule to prevent excessive wear on any of the individual modules.


With a service contract, you can build your budget with this planned expense in mind, and have MTS replace one, some or all of the modules during a convenient window in the test schedule.
