Kit - Mark V, GM5000HD

The Bedford 20-3018 is a direct-fit replacement pump repair kit for Mark V and GM5000HD airless spray systems, engineered to restore critical sealing and fluid-handling functions during scheduled maintenance or field rebuilds.

Spray equipment technicians and pump rebuild specialists rely on this kit to address wear in high-cycle pumping operations where fluid pressure and pulsing loads gradually degrade internal components. Professional painting contractors also stock this kit to minimize downtime during equipment service calls, ensuring Mark V and GM5000HD units return to jobsite-ready condition quickly.

Common reasons for replacement:

• Fluid leakage from pump housing or packing gland areas indicating seal degradation
• Pressure fluctuations or loss of spray consistency pointing to internal packing or check valve wear
• Difficulty maintaining prime or slow reprime cycles after extended use
• Preventive maintenance on rental equipment or fleet units to extend pump service intervals

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