Merkur ES spray packages
Ready-to-spray Merkur ES pump packages for air-assisted and airless finishing, designed to use less material than comparable pumps.
- 15:1 and 30:1 pump ratios
- Wall, stand and hopper configurations
Pumps · tanks · circulation · reels
Pressure fluctuations, pigment settling and worn pumps show up as finish defects. We specify and support the pumps, pressure tanks, agitators, regulators, hose and fittings that keep material moving consistently — from a single pressure pot to circulation systems feeding multiple booths.
Pumps & Fluid Handling
If you're seeing any of these, we can help — usually starting with a conversation and a visit to your floor.
- Pulsing spray patterns or pressure that drops mid-pass
- Metallics or heavy pigments settling between uses
- Pumps that need rebuilding more often than they should
- Moving material by hand from mix room to booth
- Leaking fittings, tired hose and tangled lines on the floor
Our approach
Diagnose first. Recommend second. Then make sure your team can run it.
01
Map the flow
From container to gun: pressures, distances, viscosity and how many guns you feed.
02
Size the pump
Diaphragm for gentle, low-pressure supply; piston for airless and heavy materials; circulation where colors are shared.
03
Fix the small things
Regulators, filters, hose, stainless fittings and reels that remove recurring headaches.
04
Stock the rebuild kits
Packings, seals, balls and seats quoted fast so pumps come back online quickly.
Right-sized, not upsold

Questions we hear
Do you stock pump repair parts?
Our parts catalog includes thousands of pump, hose and fitting parts. Search by part number and add them to your RFQ list.
When does a circulation system make sense?
When several guns or booths share colors, when pigments settle, or when moving material by hand is costing time and consistency.
