The Story
The Bedford 20-1920 is a direct-fit replacement pump repair kit for the 23:1 Monark pressure pump and compatible EH333 and EH300 (SD) spray systems. This comprehensive rebuild kit is engineered for spray equipment technicians, pump rebuild specialists, and professional painting contractors who service high-ratio hydraulic airless equipment in the field or workshop.
The 23:1 Monark platform demands precision components to maintain consistent spray pressure and fluid delivery on commercial and industrial job sites. This kit supplies the internal packings, seals, check balls, and valve components necessary to restore pump performance after wear, downtime, or full teardown maintenance.
Common reasons for replacement:
- Pressure loss or inconsistent spray patterns from worn internal seals and packings compromising pump chamber integrity
- Fluid leakage around rod seals or manifold connections after extended runtime or storage
- Check valve failure preventing proper one-way fluid flow and causing pressure bleed-off or reverse flow
- Complete pump rebuild cycles for rental fleet maintenance or after extended idle periods
Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
Replacement for: Graco 223-674, Graco 223674.
