Pumps DN-JN Diamond Series


 

Flanged Industrial Series

The DN and JN Diamond series is the best solution for the industrial sector in pumping a vast range of fluids. They are synonymous with strength, reliability, performance and application flexibility.

Designed according to the most demanding standards, they comply with the requirements of standard API 676.

Suitable for pumping viscous and non-viscous products, with or without solids of any nature, they are an ideal solution for those seeking a standard product with advanced technology with unbeatable cost benefits in the current single screw pumps market.

The DN and JN series are distinguished for the type of fitting of the pump to the drive

 

DN series

  • DN Series: the drive is coupled directly to the pump via a flange. This solution is extremely cost effective and compact, considerably reducing installation costs and simplifying maintenance. The forces generated by the hydraulic part are supported by the drive itself. Each drive used is adequately selected based on their specific technical parameters and are subject to numerous duration tests with heavy loads.
    The DN series is the reference point for almost all pumps installed in the industry.

  • JN Series: the drive is connected to the free bare shaft inlet via a flexible coupling. This configuration is the best solution in terms of performance and durability. All the forces generated by the pump are absorbed by the bearings in the housing. These bearings have very high resistance against loads. They are assembled with extreme precision on the highest quality manufactured parts. It is the best solution when you want to guarantee duration and reliability, yet with greater installation space requirements. The bearing unit designed by us is modular and can be adapted to a DN series pump with lantern after a pump with the JX series block housing. It is state of the art for this type of installation.
