The Brenner Base Tunnel through the Alps, destined to become the longest underground railway connection in the world at a planned length of 64 kilometers, is being excavated using tunnel boring machines, or TBMs made by Herrenknecht. The TBMs contain nearly every type of pump manufactured by Allweiler, a Circor brand;

  • Filter oil and cooling system pumps
  • Grout pumps for ring-gap mortar injection
  • Proportioning pumps with quench`
  • Water pumps

Hermetically sealed Twin-Screw Pump for chemical and petrochemical sectors

Monday, June 18th, 2018 von admin

ITT Bornemann launched a new hermetically-sealed pump, named SLW, at Achema 2018 in Frankfurt, Germany. This pump serie uses a magnetic coupling for a hermetic pump drive. With the sealed fluid chamber, critical media with harmful substances are confined to the pump and not released into the environment.

  • The design allows the two screws to convey the product and transmit the torque.
  • The single-volute design is also compact and requires a small footprint for installation.
  • The product is lubricated with inboard bearings.
  • The less-wear parts design leads to low-maintenance, resulting in high MTBF.

Twin screw pumps for food applications

Wednesday, March 21st, 2018 von admin

Hyghspin twin screw pumps have a compact design and many versatile and flexible uses. The design of these pumps do follow hygienic design criteria. Their block construction saves space and always ensures a correctly aligned coupling.

Mobile units including frequency converter and service switch are another feature of this pump range. These units stand out, among other things, on account of their self-priming qualities and ease of service. Safe-to-run dry seals, for example, require no flushing.

Multiphase pump installation allowing wells to come back to production

Wednesday, November 15th, 2017 von admin

Crosbys Creek Oil & Gas  LLC, based in Ridgeland, MS,  is an independent American producer producing in Choctow County in Northern Alabama, USA. These fields are older and have produced oil and gas for many years.  Over time the natural reservoir pressure has dropped off to a point where some wells are not able anymore to overcome the back pressure generated by the surface flow lines and the first stage separator of the process facility. The company had heard about multiphase pumping. This economic alternative caught the interest of the management as the production was expected to remain interesting for years to come.

Wangen: New hygienic twin screw pump

Thursday, October 19th, 2017 von admin

This new pump generation offers a spindle change without re-synchronisation of the spindle shafts. All you have to do is remove the housing and loosen the screws and the spindles can then be removed in order to replace the seal in a fast and straightforward manner, for example. Thanks to a self-centring flange casing, which is available as an option, the coupling is optimally aligned automatically. As a result, renewed alignment of the coupling with the pump, e.g. after service activities, is not required. In addition, the Twin guarantees a long service life, among other things, as a result of the further-developed, high-quality components and materials, such as the further-developed shafts.

Klaus Union: New twin magnetically coupled screw pump acc. API 676

Thursday, September 21st, 2017 von admin

With the proven Klaus Union magnetic drive and a modular design, the pump manufacturer offers a highly flexible and robust seal-less magnetically coupled twin screw pump: the SLM DSP-2C. Due to its seal-less design and leakage-free operation, it is especially suitable for applications in the chemical and petrochemical industry.

Due to its robust design and leakage-free operation, the new Klaus Union twin screw pump series SLM DSP-2C meets precisely these requirements. For this purpose, the pump manufacturer takes advantage of the established in-house modular pump system, which has proven itself for many years in the complete magnet drive pump range consisting of the pump hydraulic, magnet coupling and bearing bracket. High interchangeability and availability of spare parts as well as customisable suction and discharge flanges guarantee maximum flexibility to meet project requirements.
