All the advantages of the modular and low life cycle costs of the Diamond series design, in vertical configuration for demanding tank and well emptying applications
The short version is compact, robust and easy to install. This version allows installation with only anchor plate.
DV Long Series
The long version is designed for deep wells or tanks and includes additional features such as removable inlet for easy maintenance of the rotor, stator and coupling.
