Description
The Bedford 20-1178 is a direct-fit replacement for the pump repair kit designed for 5:1 Monark (Teflon) airless spray equipment. This kit equips pump rebuild specialists and spray equipment technicians with the seals, packings, and internal components needed to restore full operational capacity to Monark pump units after wear or seal failure. Professional painting contractors and rental equipment service staff depend on kits like this to minimize downtime and extend the service life of their spray rigs without sourcing multiple individual replacement parts.
Common reasons for replacement:
- Worn or degraded packing material causing fluid leakage around the pump shaft or rod
- Loss of pressure buildup due to compromised internal seals or O-ring sets
- Teflon components showing signs of cracking, deformation, or chemical breakdown
- Pressure recovery issues or inconsistent spraying performance after extended use cycles
Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
