Hermetic: 12-stage canned motor pumps for ethane cracker plant

Monday, June 6th, 2016 von admin

IMG_1941The actually supplied two canned motor pumps, with “tandem” design, convey the medium [C3 fraction with propylene as main constituent] at a temperature of 22 °C. The differential head [H] is 379 m at a flow rate [Q] of 7.8 m³/h. The pump units are designed for a nominal pressure of 40 bar and have temperature- and level-monitoring features. For online monitoring of the hydraulic axial bearing, a rotor-position monitoring feature is also provided.

The special tandem design of the multistage pumps results in minimal shaft deflection and load relief at the slide bearings. The “ZART” (Zero Axial and Radial Thrust) technology ensures a contact- and wear-free running of the rotor unit.

Hermetic: Straight from production on board the aircraft

Monday, August 19th, 2013 von admin

Hermetic canned motor pumps are known for their high Mean Time Between Failure (MTBF). However, should a pump fail, the urgency of spare part delivery is particularly high. At worst, loss of production or downtime of entire plant sections is impending. To respond as quickly as possible, Hermetic optimised not only production, processing and packaging of urgent orders, but also their dispatch: Due to classification as “Known Consignor” by the Federal Aviation Office (Luftfahrt-Bundesamt), spare parts or complete pumps may be packed ready for airfreight and dispatched at the production site in Germany. Afterwards, a freight forwarder, who is also qualified, transports the goods from the factory directly to the aircraft.
