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.

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.

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.

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.

S Series are self-priming double-ended positive displacement pumps available with or without external timing gears and bearings. Twin and triple screw designs provide complete axial balancing of the rotating screws and their timing technologies eliminate metal-to-metal contact with the pump.

S Series pumps are Atex-certified for use in explosive or dangerous environments, and have been specifically designed to address the difficult pumping challenges found in the oil & gas, process and marine industries. S Series pumps provide solutions that can meet the toughest application challenges regardless of temperature, viscosity or pressure.

Maag presents a new S Series of screw pumps that offer the process industries a variety of options for conveying challenging fluids. These rotary positive-displacement pumps provide numerous advantages over conventional technologies including

• Atex-certified for use in explosive or dangerous environments.
• Self priming capability, good suction performance
• Excellent speed/output linearity
• Low pulsation
• Constant flow even at considerably different pressures and volumes
• Compact footprint and ease of maintenance.

Single-flow hygienic Twin-Screw-Pumps, type SLH from ITT Bornemann, have been successfully installed in many applications in the food-, beverage and pharmaceutical industry for many years. It is one of the main functions to pump high viscous fluids. Because of the high rotational speed range (up to 3600 rpm) it is also possible for the pump to handle low viscous products with a high flow velocity. So it is possible to use the SLH Twin-Screw-Pumps also for the CIP-Process.

To reach the high criteria of hygienic design ITT Bornemann designs the pump inside and outside in best way without loss of functionality. As a result the pump is EHEDG EL class 1 certified and also 3-A registered. Now the SLH-4G Twin-Screw-Pump reaches the next level: EHEDG EL Aseptic Certificate. The certificate underlines the hygienic design of SLH-4G Twin-Screw-Pump and confirms the possibility to operate in aseptic applications.
