Mounting Bases Pump units should be mounted on either a concrete or metal foundation of sufficient weight and strength to properly support the entire pump unit. It should be located as close to the liquid source as is practical, while allowing for accessibility for normal pump maintenance. The foundation should be made flat and smooth to ensure correct alignment of the pump. Provisions should be made to bolt the unit securely in place. Do not locate the pump unit in a pit unless provisions have been made for proper drainage and ventilation.
Correct alignment is absolutely essential for satisfactory pump life.
Complete pump units are set and aligned at the factory on a flat surface plate and shims are inserted where necessary to provide perfect alignment. However, all baseplates are somewhat elastic and as a result we cannot assume responsibility for mechanical operation unless the shop alignment is reproduced when the unit is secured to its foundation. Since no foundation is perfectly flat or level, it is therefore necessary to shim the baseplate until the pump and motor shafts are level and parallel. Recommended drive arrangement for pump only is direct motor drive. For belt or pulley drive application, pillow block bearing must be used to achieve acceptable pump life.
