1. Features and performance
■ Similar structure as common pumps
■ AOC~160M powder was sprayed on plunger surface; Coating materials of plunger and pump barrel are optimized and helpful to reduce wear..
■ Bidirectional protection is considered for coating materials, friction reducer contents will lubricate the solid surface and protect the pump chamber
■ Valves can be customized.
2. Applications
■ Applicable to all normal wells, low-efficiency wells and deep wells. It is an ideal alternative to current conventional pumps.
■ Plunger size 32mm~83mm，stroke ≤7.5m
3. Cases history
AOF bidirectional protection pump is widely used in the onshore oilfields in China, with pump efficiency increased by 10% and pump inspection period prolonged 100%.
