# Pumps, valves and compressors

Graphite and carbon for pumps, valves, and compressors: ESGRAF advises on material selection and application support across Mexico and the Americas.

Carbon-graphite vanes, rings, seals, and bushings for rotating equipment.

Pumps, valves, and compressors depend on seals, vanes, and bushings that run with little external lubrication and in difficult media. Carbon-graphite provides self-lubrication and dimensional stability in those conditions.

ESGRAF machines components and recommends the grade based on fluid, speed, and operating pressure.

## Processes
- Mechanical sealing
- Vanes and pumping elements
- Self-lubricating bushings and bearings
- Compression and fluid control

## Challenges
- Wear in sliding contact
- Leakage from seal failure
- Dry running or marginal lubrication
- Abrasive or corrosive media

## Advantages
- Self-lubrication of carbon-graphite
- Good wear resistance
- Compatibility with many fluids
- Parts machined to tolerance
