Factory Repair Service
Our Training and Repair Facility offers
Factory Repair Services for XX Herringbone Gear Pumps.
Factory repairs save you money compared to a service call and allow us to perform additional services that
are difficult or impossible to do in the field.
XX Herringbone Gear Pumps are very robust and will last many more years with routine maintenance. In addition to basic
pump overhaul services, we offer advanced repair services and have been able to repair some severely damaged pumps
that customers thought were beyond saving.

- Replacement of pump (4) and motor (1) bearings
- Inspection and dressing of herringbone gears
- Installation of new gaskets, seals and O-rings
- Reassembly and adjustment of end clearance to OEM specs
Advanced repair services include:
- Side grinding the drive and idler gears to maintain proper centering of the gears when meshed
- Magnaflux inspection of drive and idler gear journals for cracks
