For high‑temperature medium working conditions, we adopt the 21‑type flush plan, combining metal bellows mechanical seals with heat exchangers.
This solution upgrades on the basis of Plan 11 by adding coolers to enhance heat dissipation effectively, stabilizing the seal performance and extending service life for high‑temperature pumps.
Our finished pumps with this optimized sealing system are ready for delivery, offering reliable solutions for high‑temperature industrial fluid transfer scenarios.
