This pump has a dry-running, frictionless sealing system
The TCC DryRun submerged pump has a bearing and sealing unit that has no contact with the pumping medium. The axial bearing preload ensures sufficient minimum load without any hydraulic force when the impeller is not immersed in liquid, says the company. The pump’s modular design provides operating flexibility; for instance, the basic version ensures an immersion depth of up to 2.40 m; by installing intermediate bearings, immersion depths of up to 5.50 m can be achieved. The pump has relatively low installation and maintenance costs and a maintenance interval of 3–5 years. — Paul Bungartz GmbH & Co. KG, Düsseldorf, Germany
