Wangen Pumps redesigns products
Wangen Pumps has redesigned its TWIN NG pump, improving its performance and reducing maintenance requirements, the company says. The result is a hygienic pumping solution that performs better for longer, boosting uptime and reducing lifecycle costs for customers in the food manufacturing sectors, according to the firm.
Twin NG screw pumps are designed to 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 cubic metres per hour 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 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, minimizing 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 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 base plates. 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.
