KNF, a leader in diaphragm pumps, has introduced four new intelligent pumps for flow, pressure, and vacuum control as well as versatile dosing

For liquid metering applications, KNF has developed the FMS-FC 1.400 diaphragm pump with integrated flow control , which uses a precise flow sensor and ensures precise, accurate, and stable liquid delivery. It achieves a maximum flow rate of 3.4 l/min, a maximum pressure of 6 bar (rel.) and offers a maximum suction height of 3 mH2O.

The FD 1.200 with Versatile Dosing delivers precise and repeatable volumes for demanding applications, using advanced stepper motor technology and actively actuated valves. It offers a maximum flow rate of 40 ml/min, a maximum pressure of 6 bar (rel.), and a suction height of at least 4.5 mH₂O. Compact, chemically resistant, and customisable, it sets a new standard for accurate dosing.

The new MGP 75 diaphragm gas pump with intelligent pressure control maintains precise and consistent gas pressure even under changing conditions. Using the latest KNF motor technology, it achieves a maximum flow rate of 78 l/min, a maximum pressure of 1 bar (rel.), and a maximum vacuum down to 25 mbar (abs.).

The new micro vacuum pump NVC 830 maintains exact vacuum levels in demanding environmentsusing intelligent vacuum control This compact pump delivers a maximum flow rate of 4.7 l/min and a maximum vacuum down to 55 mbar (abs.).

Special features

Each pump integrates modern sensor technology and proprietary motor control to maintain exact setpoints, even under dynamic conditions like changing pressure or media temperature. The pumps can operate autonomously or can be controlled via analog signals such as control voltage. For use in complex systems, the pumps also support modern communication protocols like UART, enabling seamless integration into smart environments.

Based on a modular design, the pumps can be customised quickly and cost-effectively. Options include material selection, electrical and line connections, and digital settings such as output setpoint, ramp-up speed or maximum motor speed limits, depending on the pump. This flexibility makes the pumps an ideal choice for critical applications in industrial processes.

Turkish Petroleum Offshore Technology Center AS has secured extension contract with Subsea7 on the Sakarya field development in the Black Sea offshore Turkiye

Building on the original contract announced on 27 August 2025 for the third phase of Sakarya, the extension will ensure connecting the recently discovered Goktepe field to the Phase 3 floating production unit.

The scope of work comprises engineering, procurement, construction and installation (EPCI) of approximately 20 kilometres of flexibles, 120 kilometres of umbilicals, a rigid production riser and associated subsea equipment in water depths of 2,200 metres.

Project management and engineering will be coordinated through the Subsea7 office in Istanbul, Turkiye, before offshore activities begin in 2027 and 2028.

David Bertin, Senior Vice President of Subsea7’s Global Project Centre – East, said: “We are proud to continue to support TP-OTC in their ambitions in the Black Sea with the development of the Goktepe field, which will enable increased production through the Sakarya Phase 3 facilities and support Türkiye’s gas needs.”

Hulya Ozgur, Business Unit Director Subsea7 Türkiye, said, “We look forward to continuing our long-term relationship with TP-OTC, which is making a significant contribution to the development and growth of the Turkish energy industry.”

Technological advancements in geoscience are often incremental—small steps that help refine our ability to understand the subsurface. But occasionally, we witness a genuine leap. DUG Technology’s Chief Geophysicist, Tom Rayment, considers the impact of elastic MP-FWI imaging and asks, "Is traditional seismic processing finally a thing of the past?"

For the past century, seismic data has been an invaluable tool for detecting hydrocarbons. Although methods have become more sophisticated, the fundamental workflow for turning acquired data into interpretable products largely remains the same. The advent of elastic multi-parameter full waveform inversion (MP-FWI) imaging represents a significant shift away from the traditional approach.

The acoustic MP-FWI imaging implementation has demonstrated significant uplifts without needing conventional time-processing, model-building, or depth-migration techniques. Elastic MP-FWI imaging is a further step-change, also deriving rock properties and effectively rendering the amplitude variation with angle (AVA) inversion workflow redundant. The approach will soon make conventional workflows obsolete, if it hasn't already.

Despite this monumental leap, the technology is still young, with ample room for more progress. Most FWI implementations use a single component of the acquired data (hydrophone for marine, vertical geophone/accelerometer for land). However, additional components offer complementary information that can further constrain results. Recent developments show that two-component towed streamer and ocean-bottom seismic MP-FWI imaging can further improve results and accelerate convergence.

The logical next step is to include horizontal components. Shear waves provide valuable subsurface information, especially in areas of strong P-wave absorption like gas bodies. Recent DUG projects are already demonstrating that the benefits of converted-wave processing can be realised with elastic MP-FWI imaging. Furthermore, on land, exploiting shear waves in the form of ground roll is now viable. What was once noise is now a useful signal, inverted via elastic FWI to provide high-resolution shear-wave-velocity models. Capturing near-surface complexity is crucial for successfully illuminating deeper targets.

Another benefit is the seamless integration of expertise. Processing, imaging, and quantitative interpretation geophysicists can now work simultaneously on a project, abandoning the siloed conventional workflows. Closer collaboration fosters better understanding, which translates to optimal results. This will soon extend beyond AVA inversion into reservoir characterisation and modelling. Elastic MP-FWI imaging will produce a suite of outputs, providing a rich model space for reservoir engineers to make probabilistic predictions that honour both seismic and well data.

This technological leap was first conceived by the FWI pioneers in the 1980s. Its reality today is thanks to the skills of research and development teams and modern high performance computing. This essential work continues in earnest at DUG; as the technology evolves, it will continue to extend what is possible with seismic data, ultimately allowing the industry to make better, faster decisions.

Manufacturing company, WEG, has introduced a digital tool called Gear ProSelect, that will simplify and standardise the selection, configuration and documentation of gearboxes and gearmotors

Developed as a single global solution, the tool ensures consistency for sizing across regions while reducing the time typically required for manual calculations or engineering support. 

As the gearbox market expands alongside industrial automation, it can shoot up to US$33.4bn this year. To match the market dynamism, clients require standardised and digitally-driven selection methods.

With this thought, WEG has developed Gear ProSelect (GPS) which lets users size and configure gearboxes directly through a web-based platform using application-specific data. By entering parameters such as mass, speed and inertia, users receive product recommendations supported by integrated mechanical and thermal validation.

The thermal validation feature represents a unique differentiator in the market. Thermal validation analyses heat generation and dissipation under defined operating conditions, ensuring the selected gearbox can operate within acceptable temperature limits and reducing the risk of overheating or premature wear.

“Gear ProSelect represents a major step forward in WEG’s digital transformation strategy,” said Marcio Yoshikazu Ematsu, European marketing manager at WEG. “By combining intelligent validation, real-time visualisation and global standardisation, we are providing customers with greater autonomy while strengthening operational efficiency across our worldwide network.”
