1. Optimized Sand Management: Our elastic seal pump has a unique feature of 45° spiral guide groove design between sealing stages. This led to a 60% increase in sand discharge efficiency, cutting down the problem of pump clogging in high-sand environments by a great margin. 2. Elastic seal sucker oil well pump incorporates all-metal structural parts that have undergone special heat treatment (QT800-10 material). These pumps can keep their sealing performance even when used for steam drive (350°C). 3. Elastic seal sucker oil well pump contains a built-in tungsten carbide guide sleeve (hardness HRA92) that makes it compatible with horizontal wells having well inclination angle ≤90°.
