Graco XT Mark VII Standard Hi-Boy Pump Breakdown (2001556) Parts Guide
XT Mark VII is the heavyweight of Graco’s electric texture line, packing a brushless MaxPower DC motor that drives a full-stroke Endurance Chromex pump to 3300 psi while moving up to 6.4 L / min (1.7 gpm). That’s roughly 40 % more output than a Mark V, enabling crews to finish block-fill and elastomeric roof coatings in fewer passes. A Hi-Boy cart keeps the 126-lb frame nimble, and SmartControl 4.0 holds fan pattern even when voltage or viscosity drifts on site.
Graco’s 3-in-1 architecture adds job-site flexibility swap the fluid section for a mortar pump, or hook to a remote hopper for low-pressure texture without buying a second rig. The WatchDog system shuts down the pump if material runs dry, saving the rod from a heat-stroke.
The Heart of the System: Pump Breakdown 2001556
Part 2001556 is Graco’s factory-built displacement pump for every XT Mark VII Standard Hi-Boy shipped worldwide. It arrives pre-packed with V-Max Blue seals, carbide seats and a stainless steel ball set ready to bolt on with ProConnect ½-turn fasteners three minutes from box to spraying. The same pump cross-fits older Mark V XT rigs and even 695 XT models, so stocking two lowers covers most of a mixed electric fleet.

Maintenance Blueprint—Hit 2× Pump Life
Before Each Shift – Lubricate throat with TSL, check for ½-inch belt deflection, and confirm WatchDog float action.
Every 250 hours – Replace inlet strainer, scrape piston rod, and torque pump fasteners to 55 in-lb.
Every 500 hours – Install a new seal kit, purge SmartControl memory, and pull motor brushes for wear check.
Annually – Drop in a fresh 2001556 pump, pressure-test to 3000 psi, update BlueLink hours, and archive flow data.
Pro Tips
- Color-code parts bins—blue for electronics, red for wet-end, yellow for filters to cut pick errors 50 %.
- Keep an “A-bin” of graco spray pump parts, plus one spare gun per crew; lightning surges fry guns more than pumps.
- Use the larger 60-mesh inlet filter when spraying elastomeric roof coat to prevent cavitation at 120-ft hose runs.
- Log every gallon via BlueLink; contractors report 20 % faster warranty claims with digital usage proof.
