· Belt transmission: Power is transmitted by a long life heavy-duty belt, whose elastic cushion effect absorbs impact in reverse action and results in uniform reciprocal movement of the rod string
· Long, slow strokes: Long stroke leads to high pump fill and less fluid impact; Low stoke means less wear on downhole equipment
· Fairly complete production supporting system ensures the unit to be used with big pumps for more fluid lift and small pumps for deep well applications
