THBC tubing pump is the bottom cup seating, barrel assembly is connection on the tubing string.
Fixed type tubing pumps standing valve assembly is attached below the pump barrel as part of the tubing string. A larger valve can be installed than with a retrievable type but the tubing must be pulled in order to repair it.
