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.

Lewa: Hermetically tight 170 °C high-temperature pumps for production

Wednesday, December 17th, 2014 von admin

Wacker_freiIn the existing chemical installation in a Wacker Chemie plant, the safety-related design of the relevant pump systems had to be thoroughly renovated. One of the basic requirements for the redesign was that diaphragm pumps themselves had to remain absolutely hermetically tight, even at high working temperatures of +170 °C during normal operations and brief peaks as high as +200 °C. As a result, Lewa developed an individual solution to meet the specific customer requirements.

“As an additional security measure, the pressure-free hydraulic reservoir behind the diaphragm is blanketed with nitrogen as a protective gas”, explains Lewa project lead Rainer Sonnenfroh.

HNPM: Hermetic micro annular gear pumps

Wednesday, January 15th, 2014 von admin

mzr-4661-tech-zeichnungThe magnetic driven, hermetic series of micro annular gear pumps has been extended with regard to size and drive options. These pumps are suitable for handling

  • crystallizing,
  • air or moisture-sensitive liquids

because the pump has no shaft seal. This feature is made possible thanks to a liquid-separating cup surrounding the magnetic drive. Long service life, leak-free operation, low energy consumption and an integrated speed controller characterize this pump series of the German HNP Mikrosysteme GmbH just like the compact measurements of the pump with a minimum diameter of 22 mm and a minimum length of 69 mm.
