Variants

DX Series

The motor is directly coupled to the pump by means of a flange. This solution is extremely cost-effective and compact, significantly reducing installation costs and simplifying maintenance. The forces generated by the hydraulic part are supported by the motor. Each motor used has been suitably selected according to strict technical parameters and has been subjected to numerous durability tests under heavy loads. 

DX Series

JX Series

The motor is connected to the pump input shaft via 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 support. These bearings have a very high load resistance. They are mounted with extreme precision on components of the highest quality. ' It is the best solution when you want to ensure maximum durability and reliability, while requiring larger installation spaces. The bearing holder designed by us, is modular and can be installed later in a pump with monoblock holder of the JX series. Represents the state of the art in this type of installation. 

JX Series

Serie FX

The motor is directly coupled to the pump via the flange of the bearing support module. This solution is the most versatile as it allows the use of standard flanged gearboxes and output shaft, coupling with hydraulic or pneumatic motors, maintaining the simplicity and compactness of the classic monobloc solution while guaranteeing total reversibility and superior bearing support performance. 
This bearing support module can be applied to the entire Diamond series and allows for quick maintenance of the motor drive. FX is therefore synonymous with modularity and reliability with any type of motor.

Serie FX

DXC series

The DXC series is the standard joint sanitary pump of the DN series. It is the solution that combines excellent sanitizability characteristics thanks to the casing design completely free of dead zones and stagnation, together with the performance of the patented pin joint of the Diamond series. The lubrication of the joint is independent of the pumped product, so it is also suitable for abrasive fluids.

DXC series

Series DXO

The DXO series is the open-ended sanitary pump. ' It is the solution with the best characteristics of sanificabilità thanks to the design of casing and rotators completely free of dead zones and stagnation. The joint, of type with pin has been appropriately dimensioned to guarantee a long life. The lubrication of the joint is guaranteed by the product itself thanks to the open type design, therefore it is suitable for non-abrasive fluids. Performance greatly improved in the pumping of lubricating products

Series DXO

DXO series EHEDG design

The DXO series made with a EHEDG (European Hygienic Equipment Design Group) design casing represents the open-ended sanitary pump with the highest concept of sanitization in the washing cycle phase.  It guarantees internal cleaning with a washing cycle like the standard DXO pump but reduces up to 35% of the flows and quantities of products used during cleaning, obtaining an economic saving. In addition, a lower flow rate during the washing phase corresponds to a lower amount of chemicals used and therefore less stress on the hydraulic components, such as the stator, and thus longer component life. 

DXO series EHEDG design

DXF series

The DXF series represents the sanitary pump with a plug without sleeves. ' It is the solution with the best characteristics of sanificabilità thanks to the design of casing and rotators completely free of dead zones and stagnation. The joint is designed to be perfectly hygienic and free of dead zones, suitable for any type of fluid.
