Description
The Bedford 20-3551 is a direct-fit replacement repair kit for the 63:1 King airless pump, a high-ratio hydraulic sprayer used in demanding industrial coating and professional painting applications.
Pump rebuild specialists and spray equipment technicians rely on this kit to restore King pump performance when internal components begin to degrade. The kit contains the packings, seals, and O-rings necessary to return the pump to OEM specification without requiring full component replacement.
Common reasons for replacement:
- Seal degradation causing pressure loss or fluid leakage around the piston rod
- Packing wear resulting in reduced spray pressure or inconsistent atomization
- O-ring failure leading to internal fluid bypass and reduced pump efficiency
- Routine preventive maintenance during scheduled pump overhauls or equipment servicing
Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
