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.

Blackmer: Screw Pumps for Bitumen Transfer Applications

Tuesday, April 18th, 2017 von admin

Traditionally used as a cement binder for hot-slab paving, liquid bitumen must be handled at very high temperatures in order to keep it at a workable viscosity. However, even at high temperatures liquid bitumen can be an extremely viscous and shear-sensitive product. Therefore, shipyard operators and tanker owners demand a pumping technology that has been specifically designed to transfer highly viscous liquids over great distances. Realizing the importance for pumping equipment that feature the design and performance characteristics required for transferring highly viscous liquids, Blackmer offers its S Series Twin Screw models for these marine applications.

Fristam adds double-screw technology to its pump portfolio

Thursday, May 12th, 2016 von admin

FDS_mit_FoerderschraubenThe pump casing of Fristam FDS pumps comes in three parts, consisting of an intermediate flange, the screw casing and the pump cover. This enables individual adaptation of the connections to any conceivable production system requirement. Thanks to central positioning of the gearwheels inside the bearing support area, the entire pump comes in a very compact design. Moreover, its massive shaft has reinforcements in the area of critical diameters to ensure maximum rigidity. Further stability is achieved through a combination of particular large bearings and an increased bearing distance. The result is smooth running with minimal wear.
