The Bedford 20-1328 is a direct-fit replacement pump repair kit for Graco 30:1 Bulldog, GH533, and 63:1 King airless sprayers. This comprehensive kit is engineered to restore critical sealing and internal components across this family of high-performance displacement pumps, making it an essential service item for spray equipment technicians and pump rebuild specialists managing fleet maintenance or customer equipment repairs.

Repair kits for these pump models typically bundle packings, seals, O-rings, check balls, and other internal wear components that degrade under pressure cycling and fluid exposure. Professional painting contractors operating rental equipment or their own fleets rely on kits like this to extend pump service life and avoid downtime during peak season spray jobs.

Common reasons for replacement:

• Pressure loss or spray inconsistency caused by worn packing assemblies and compromised primary seals
• Fluid leakage around rod packing areas or manifold block sealing surfaces
• Loss of prime or reduced displacement after extended run hours
• Internal component degradation from abrasive fluid residue or environmental corrosion

Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
