Service & Repair – Sun Pumps

If we built it, we'll fix it.

Sun Pumps offers both in-house and field service on all of its parts. Whether it’s troubleshooting, refurbishment, or a full rebuild send it to the people who built it.

In-House & Field Services

Two ways we'll get you running.

Track 01

For In-House Repairs

When something goes wrong, you shouldn’t have to hunt for answers. Sun Pumps offers full in-house repair services to get your system back up and running quickly and correctly. Our technicians know these pumps inside and out. We only use genuine replacement parts to ensure long-term performance.

Whether it’s troubleshooting, refurbishment, or a full rebuild, send it to the people who built it.

For all repairs, please call 928-348-9652 and ask for an RA (Return Authorization) number. Write this number on your shipping label and send it to:

Sun Pumps, Inc.

325 E Main Street
Safford, AZ 85546

Track 02

For Field Service

Sometimes, the best solutions happen on-site. We offer in-the-field service local to southeastern Arizona, where our team can come to you to troubleshoot, diagnose, and get your system performing the way it should. Outside our local area, we’ll route you to a certified Sun Pumps dealer with a field-service truck closer to your property.

If you’d like to repair an SDS pump yourself, check out our Pump Service Kits for genuine replacement parts, or give us a call on our toll-free number for assistance. You can also watch the Do-It-Yourself SDS Pump Series Rebuild videos in the Media Library for step-by-step guidance.
