The pumps offer the quality and durability the Waukesha Cherry-Burrell brand is known for while optimizing cost and suitability for the industrial market. 

The U2 ND series significantly expands the WCB pump range, aimed at enhancing reliability and performance across industrial applications while outperforming other pump styles, such as industrial lobe, gear or progressive cavity pumps. 

The design features improvements uniquely suited for industrial applications, including: 

  • Total cost of ownership: The pump ensures a long running life, given its robust construction materials and designs tailored for each application. Because of its high volumetric efficiency, the pump can be used to dose fluids, eliminating the need for an additional metering pump. 
  • Efficiency: The U2 ND pump reduces slip, which occurs when fluids move backward from the liquid flow due to internal clearances. Lower slip means more efficiency, reducing the need for higher horsepower motors. Also, the series can process fluids over longer spans due to its high-pressure capability, which reduces the need for multiple pumps in these applications. 
  • Reliability: WCB is a proven and trusted global brand dating back to the 1880s. The pumps are made with durable, corrosive-resistant materials compatible with industrial environments. A robust design, equipped with industrial flanges or sanitary fittings, ensures manufacturers can choose the configuration to meet their needs.

Built upon Yokogawa’s second generation of TDLS analyzers with improved reliability, quick response time and reduced maintenance, the TDLS8220 is a direct replacement for the first-generation TDLS220. 

The original platform of the TDLS200 was developed due to the U.S. Department of Energy (DOE) program, “In-situ sensors for the chemical industry.” The product was released in 2005 and achieved success in many different process applications and in a variety of industries, with > 1,500 units sold worldwide. 

The TDLS8220 is being introduced to complement Yokogawa’s existing TDLS product lineup to satisfy the need for extractive oxygen measurements where in-situ or probe-type installations are not applicable and where traditional technologies fall short. 

The TDLS8220 laser module and detector module are now encompassed in one board set, but still retain a reference cell for improved reliability of absorption peak detection. In addition, the auto gain function automatically optimizes detection sensitivity during dynamic process events. Due to the non-contact measurement, sample handling system upsets or failures will not damage the analyzer sensor. The TDLS8220 plays a key role in ensuring accurate and reliable oxygen measurements for safe continuous operation. 

The unique flow cell design features a tube-in-shell construction that allows tight temperature control of extractive samples at the desired set point. The analyzer does not require consumables, and solid-state technology eliminates the need for routine calibration. The TDLS8220 supports field serviceability with onboard diagnostics and 50 d of data and spectral storage to identify and correct minor issues before they turn into serious problems. 

Major target markets include the oil and gas, petrochemicals and specialty chemicals segments, with applications ranging from marine vapor recovery and oxygen monitoring in ethylene oxide production, to safety related limiting oxygen concentration (LOC) measurement and other process oxygen measurements.

Complete high-pressure marine pump unit for LNG fuel 

High-pressure liquefied natural gas (LNG) engines offer lower fuel consumption and significantly reduced methane slips. This is driving a surge in demand for crucial components for LNG high-pressure fuel supply systems, which Svanehøj is now ready to meet. 

Drawing from extensive expertise in cryogenic solutions, the Danish marine pump specialist has developed a high-pressure fuel pump unit with a drive system and three combined cold ends designed for optimal flow and longer service intervals. The new solution is called HPP Triplex Unit.  

It is evident that more integrators of fuel gas supply systems are taking on a progressively substantial role in designing fuel supply systems, especially for LNG-powered vessels. Therefore, they increasingly require critical components specially designed to operate under extremely low temperatures and high pressures. Based on decades of experience in low-pressure fuel and cargo pumps for LNG, Svanehøj made a strategic decision to extend its scope and include a larger part of the LNG fuel supply system by developing a high-pressure pump unit, exclusively designed for maritime purposes. 

Svanehøj has designed the HPP Triplex Unit (FIG. 3) to meet the maritime industry's demands for leak-free critical components with a long service life. The cold end includes an innovative low-pressure sealing arrangement that reduces friction, ensuring longer service intervals. To further reduce maintenance costs, Svanehøj has developed a cartridge solution for swift sealing replacement. To ensure high efficiency and low-pressure drop, Svanehøj has also incorporated a new inlet valve design. 

FIG. 3. The Svanehøj HPP Triplex unit is a triplex type high-pressure piston pump for LNG, with a belt drive system, installed on a skid for easy transportation and installation. 

As part of its ESG strategy, Svanehøj is committed to directing 95% of its R&D investments at solutions and products that support the energy transition in hard-to-abate sectors. This includes pumps and equipment for carbon capture, Power-to-X and LNG. In recent years, Svanehøj has invested significantly in new products and services for the LNG segment, including a new submerged fuel pump, launched in 2022, and the 2023 acquisition of the U.S.-based specialist in service and overhaul of LNG pumps, Complete Cryogenic Services (CCS). 

In an ideal scenario, all ships would immediately begin operating on carbon-free fuels. However, it will take several years to establish an infrastructure to meet the need for liquid renewable energy. Transition fuels are essential for a successful energy transition, and natural gas is by far the best option, offering significant environmental benefits. 

The uptake of LNG has been high in recent years, especially among new builds. According to the DNV database for alternative fuels, there are now 431 LNG-powered ships in operation and another 539 ships on order, bringing the total count close to 1,000 vessels. In 2021 and 2022 alone, 462 LNG-fueled ships were ordered, and in the first 9 mos of 2023, a further 104 ships were added to the global order book. 

The HPP Triplex unit is a triplex type high-pressure piston pump for LNG, with a belt drive system, installed on a skid for easy transportation and installation. Features include: 

  • 3 pcs. of cold ends 
  • ATEX motor downrated for VFD operation
