Instead of the impeller being directly keyed to the motor shaft, there are separate motor and pump shafts joined together by a rigid vertically split coupling. This feature combines the major benefits of VICC and Base Mounted End Suction (BMES) pumps into one smart unit. The VISC pump style hasn’t been around as long as the VICC and BMES styles. So, how does it compare?   - The VISC shares the following benefits with the [VICC](https://blogs.heattransfersales.com/blog/vertical-inline-close-coupled-pumps) Pump: - Same wet end (volute) and performance curves - Also, nearly vibration free due to perpendicular shaft orientation - No shaft alignment required – the split coupling cannot be installed without the motor and pump shafts being perfectly aligned - No base to grout - The VISC also shares these benefits with the [BMES](https://blogs.heattransfersales.com/blog/base-mounted-end-suction-pumps) Pump: - Available in most of the same capacity ranges (up to 14” pipe connections) - Separately coupled motor may be serviced without disturbing the wet end (volute)   ![Screen Shot 2016-11-15 at 10.40.10 AM.png](https://blogs.heattransfersales.com/hs-fs/hubfs/Blog_images/Screen%20Shot%202016-11-15%20at%2010.40.10%20AM.png?width=192&name=Screen%20Shot%202016-11-15%20at%2010.40.10%20AM.png)But here is how the VISC pump outshines both the [VICC](https://blogs.heattransfersales.com/blog/vertical-inline-close-coupled-pumps) & [BMES](https://blogs.heattransfersales.com/blog/base-mounted-end-suction-pumps) pump: *the rigid vertically split aluminum coupling allows you to service the mechanical seal without removing the motor or disturbing impeller.* Once the coupling is removed, just two bolts and a cap over the mechanical seal make for a quick and easy repair.   Some may argue that the VISC pump is the easiest to install, maintain and service of the four styles we have discussed in this blog series. Do you agree? If the Vertical Inline Split-Coupled Pump is the best of both worlds (inline vs. BMES), then why not use them more?  Let us know what you think!  If you need help in selecting pumps for your application, please contact your local manufacturer's rep!   ###### About The Author [More from this author](https://blogs.heattransfersales.com/blog/author/kelly-patterson) ![](https://blogs.heattransfersales.com/hs-fs/hubfs/Blog_images/10801587_10152577444568382_8583161712827376882_n.jpg?height=100&name=10801587_10152577444568382_8583161712827376882_n.jpg) ###### Kelly Patterson Kelly Patterson is an avid fan of marketing HVAC and plumbing equipment and does it on a daily basis for all the Hoffman family of companies. #### Recommended Articles [![Taco Comfort Solutions: The Ideal Pressure Boosting Solution](https://blogs.heattransfersales.com/hubfs/Taco%20Comfort%20Solutions%20The%20Ideal%20Pressure%20Boosting%20Solution%20.png)](https://blogs.heattransfersales.com/blog/taco-comfort-solutions-the-ideal-pressure-boosting-solution) ###### [Taco Comfort Solutions: The Ideal Pressure Boosting Solution](https://blogs.heattransfersales.com/blog/taco-comfort-solutions-the-ideal-pressure-boosting-solution) -
