The Bedford 20-751 is a direct-fit replacement pump repair kit for 5:1 Monark, 10:1 Pres, and Viscount 1000 airless spray equipment. This comprehensive kit supplies the internal packings, seals, and wear components that pump rebuild specialists and spray equipment technicians need to restore these three popular pump models to full operational capacity.

Professional painting contractors and rental equipment service crews rely on this kit to minimize downtime by completing pump overhauls in-house rather than waiting for factory rebuilds. The standardized components in this kit address the common wear patterns found across all three pump configurations, making it a practical choice for shops that service multiple equipment lines.

Common reasons for replacement:

• Internal packings deteriorate after prolonged exposure to paint, coatings, or solvents, causing fluid leakage around the pump rod
• Seals harden or crack under thermal stress and pressure cycling, reducing pump efficiency and output volume
• Worn check balls and seats result in pressure loss, reduced spray pattern consistency, or inability to reach target PSI
• Elastomer components swell or shrink due to incompatible fluid chemistry, compromising the pressure-tight seal

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