Description
The Bedford 20-1526 is a direct-fit replacement pump repair kit for Graco Ultra 400/500 and EM380/390/490 airless sprayers, engineered to restore worn or damaged internal components during scheduled maintenance or emergency field repairs.
Pump rebuild specialists and spray equipment technicians rely on this kit to bring aging or underperforming units back to full operational capacity without requiring a complete pump assembly replacement. Professional painting contractors managing fleet equipment also use this kit to extend equipment life and minimize downtime between jobs.
Common reasons for replacement:
- Internal seals or packings degraded, causing pressure loss or fluid leakage around the pump rod
- Check balls or seats worn or stuck, resulting in incomplete pressure cycling or loss of prime
- O-rings hardened or compressed from extended use, leading to bypass or inconsistent spray patterns
- Piston or valve components worn smooth, reducing pump efficiency and delivery consistency
Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
