Single Screw Pumps | DIAMOND

Progressing Cavity Pumps H series

hopper pumps for industrial and environmental sectors

The Diamond Series with hopper an auger feed screw to directly convey the product to hydraulic part, are the ideal machines for pumping viscous and non-flowing, with a very high solids content.
DH ,JH and FH Series is the basic version with rectangular hopper and auger feed the hydraulics. The length is customizable depending on application. Suitable for pumping substances poorly flowing up to 18% of dry substance which does not tend to form a bridge. The DH, JN and FH series are distinguished for the type of fitting of the pump to the drive.

Variants

DH 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.

DH Series

FH Series

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. Therefore FH is synonymous with modularity and reliability with any type of motor.

FH Series

JH Series

The solution represents 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 DH series. Represents the state of the art in this type of installation. 

JH Series
