The Story
The Bedford 20-2774 is a direct-fit replacement pump repair kit for the Mark IV airless sprayer, engineered for technicians and contractors who service high-volume coating equipment in the field or shop.

Common reasons for replacement:
- Pressure loss or inconsistent spray patterns indicating worn internal seals and packings
- Fluid leakage from pump housing or rod seal areas during operation
- Sluggish pump priming or delayed pressure buildup on startup
- Scheduled preventive maintenance after extended operating hours or seasonal storage
