Wangen Pumps enhances design of TWIN NG pump

The enhanced Twin NG pump has machine feet rather than a solid base plate, enabling precise alignment with pipework, improving access for servicing, and reducing contamination risk by making washdown easier.
The dependable TWIN NG pump from Wangen Pumps has been improved in design, greatly increasing its performance and lowering maintenance needs.
For clients in food manufacturing industries, Wangen Pump said the outcome is a tested sanitary pumping solution that works better for longer periods of time, increasing uptime and lowering lifecycle costs.
Martin Stümpfle, product management Wangen Pumps, noted the constant improvement to pump performance and the benefit to customers’ operations.
“The technical improvements we have made to our popular Twin NG pump deliver advantages ranging from contamination risk reduction to longer service life,” he explained.
Twin NG screw pumps are designed to reliably handle low to highly viscous, volatile, or gaseous products in applications that demand maximum hygiene and efficiency. Available in several sizes, the TWIN pumps offer a maximum flow rate of 200 m³/h and a maximum differential pressure of 25 bar.
The first design enhancement involves replacing the Twin NG’s motor coupling with a lantern coupling. This innovative feature prevents pump shaft misalignment, which reduces stress and vibration, thereby enhancing the lifespan of the pump and motor. With less wear on pump shafts and bearings, maintenance requirements are minimised, and service intervals are extended.
When maintenance is necessary, it is easier to perform since no shaft alignment is required. This lantern design thus lowers the total cost of ownership (TCO) and optimises uptime. Another benefit of the new lantern design is smoother operation in demanding conditions, particularly where the Twin NG is used to pump viscous and abrasive fluids under high pressure. The lantern coupling also enables better sealing arrangements, minimising leaks and the risk of product contamination.
The second design improvement to the Twin NG pump is the option to install the pump using hygienic machine feet instead of a base plate. These feet are much easier to clean than traditional base plates because they minimise surfaces where dirt and bacteria can accumulate, greatly reducing the risk of hidden contamination associated with solid baseplates. The individual feet also facilitate more effective wash-down and drainage, without the need for elaborate drainage slopes and holes.
Like the pump’s lantern coupling, the machine feet help to dampen noise and vibration, reducing wear on the pump and associated equipment. Individually adjustable, machine feet enable precise levelling, making it easier to align the pump with existing piping and reducing the risk of errors during installation.
The feet also provide better access to the pump during routine maintenance, whereas base plates may require disassembly before vital components can be reached. Machine feet therefore improve pump availability by reducing servicing time.
Additional benefits of machine feet include a better ability to compensate for thermal expansion, preventing damage to the pump and piping, as well as better stability during maintenance at the pump’s fluid end.
“The improved Twin NG exemplifies our commitment to listening to our customers, understanding their business needs, and refining our pump designs to deliver improvements in performance, cost and serviceability that contribute to greater overall efficiency and productivity,” concludes Martin Stümpfle.
