When the submerged pump fluid depth is longer, we call the long axis submerged pump. Jinan Warwick pump with a reliable way to connect the shaft and a unique structural design to solve the long axis of liquid pump shaft lubrication and rigidity problems, the pump shaft coupling coupling, external coupling sleeve, casing wall open Hole, so that the media into the sliding bearing. At the pump outlet there is a take over to each of the lubricated bearings and when the fluid level is below the plain bearings, lubricate the plain bearings. Long axis liquid under the pump can guarantee all the medium inside the media pumping light. When the long axis liquid pump delivers easily vaporized liquids, there is a seal at the pump outlet tube and submerged pump bracket to prevent leakage of the media gas.
