Vertical Spindle Pump
A notable feature of the BW-VS85, as with all Black Widow technology, is its availability as a High-Performance Kit. These kits are specifically developed to upgrade an old and inefficient pump with state-of-the-art technology. IT’S NEW TECH FOR YOUR OLD TECH. Although most vertical spindle pumps are used in non-severe wear applications, this doesn’t mean that their performance is acceptable. By redesigning the BW-VS85 for improved efficiency, even when compared to the VS100, less energy is wasted. When operating near or at a pump’s natural frequency, high vibration levels can occur. This can be detrimental to a pump’s operation and lifespan. Therefore, this fully assembled pump has been designed with an increased critical frequency to combat the issue.
