Traveling-barrel ,pumps, are widely used when ,sand, production is a problem; their main advantages are listed below. • The traveling barrel keeps the fluid in motion around the hold-down, preventing ,sand, or other solids from settling between the seating nipple and the hold-down. Therefore, pulling of the pump assembly is usually trouble-free. •
