Frequently Asked Questions

How long does it take to reverse engineer a part?

Repair time varies depending on the part which needs to be reverse engineered. Contact us directly to get a time estimate.


How does Reverse Engineering work?

Our team will start by replicating your component using a FARO arm and Solidworks CAD. Next, our engineers will modify the model to ensure accurate fit and perform as a brand new OEM component. We will then fabricate the patterns in-house and procure castings from local foundries. Once the castings are inspected for quality, they enter our machine shop for machining and final QC inspection before shipping.


What information is needed to get a quote?

If possible, part numbers for the pump and seal, and the pump size. If you’re missing information, don’t worry. Send us what you know and a digital picture of the seal next to a tape measure and we’ll do the rest.

How long does it take to make a seal?

Repair or production time varies depending on your requirements. For an accurate time estimate, contact us directly.


Do you repair or replace seals?

We have the in-house capability for repairing most sizes and types of mechanical seals with surface grinding, lapping, and carbon face manufacturing. We stock over 1,000 new mechanical seals of both component and cartridge type with replacements for John Crane, Burgmann, Flowserve, and more.


What information do you need to get a quote?

If possible, provide us with the pump size, and model number and the OEM part number. If you don’t have that information, no problem. Send us some digital pictures of the pump and any area of concern with a tape measure held next to it. We’ll do the rest.


How do you Reverse Engineer new parts?

Our team will start by replicating your component using a FARO arm and Solidworks CAD. Next, our engineers will modify the model to ensure accurate fit and perform as a brand new OEM component. We will then fabricate the patterns in-house and procure castings from local foundries. Once the castings are inspected for quality, they enter our machine shop for machining and final QC inspection before shipping.


Do you carry discontinued parts?

We don’t carry discontinued parts but may be able to reverse engineer them. Contact us to find out how we take old, worn down parts and make new replacements.


Is there a warranty?

We bring the pumps that we repair to like-new specifications, and provide a one year warranty on all industrial pump repairs.


How long does it take to repair a pump?

The time it takes to repair a pump depends on the type of repair required and the condition of the pump. Contact us directly to get a time estimate on your repairs.


What kind of pumps do you repair?

We repair gear pumps, diaphragm pumps, positive displacement pumps and specialize in the repair of centrifugal pumps including electric submersibles.


What is the pump repair process?

Tell us what you need repaired.

We’ll come pick up your pump, take it apart, assess it and generate a quote and a report with pictures. This document details the condition of the equipment, and the scope of work required to repair it. Once you’re satisfied with our statement of work, we will complete the repairs and ship your equipment back to you.
