The Bedford 20-3330 is a direct-fit replacement for the packing repair kit used in Merkur LW075A 75cc pump units, essential maintenance inventory for pump rebuild specialists and professional spray equipment service technicians performing mid-life overhauls or emergency repairs on this compact displacement model.

Packing deterioration in the Merkur LW075A reduces seal integrity and increases fluid leakage around the rod, forcing technicians to repack the pump during routine service intervals or after extended seasonal operation. This kit supplies the necessary packing components to restore proper rod sealing without requiring full pump replacement, making it a cost-effective solution for shops maintaining fleets of rental or contractor-owned equipment.

Common reasons for replacement:

• Visible fluid weeping or dripping around the pump rod after seasonal storage or high-hour operation
• Increased pressure loss or reduced spray consistency indicating compromised packing integrity
• Routine preventive maintenance during pump rebuild cycles or equipment refurbishment
• Replacement of hardened or compressed packings that no longer maintain adequate load

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