Issues with selecting high-temperature heavy oil pumps? ?
Thread Content
Our facility has several heavy oil pumps that use dual-sealing systems with white oil for lubrication and flushing of the seals. However, the lubrication lines for heavy fluids tend to get clogged, preventing effective lubrication; moreover, the mechanical seals often leak. Do any of you have experience with this issue? Are there any other types of pumps that would be more suitable for handling high-temperature heavy oil fluids? A pump that is easy to use and maintain.
There are no better pump types. It is recommended to use light diesel externally for flushing the seal.
Use 32+52A or 32+53B. For 32, it’s best to use paraffin oil so that the pump doesn’t get clogged; for 52 and 53B, use white oil. If choosing a pump type, a centrifugal pump is still the best option; imported pumps can also be used.
