Progressing Cavity Pumps HSB series

With modul B for heavy industry and envitonmental sector

Series with hopper an auger feed screw to convey directly the product to hydraulic part, are the ideal machines for pumping viscous and non-flowing, with a very high solids content.
The HS series are the hopper rectangular version with increased auger feed screw to the hydraulics.

The module B with a Brdige braker wheel.
It performs the function of avoiding the bridge on the auger, going to improve the power efficiency the same hydraulics. At the ends of the shafts are installed soft packing seals on sturdy supports.
This construction avoid stagnation and dead zones.

Suitable to pumping non flowing product up to 40% of dry that tend to create bridge or blocks that shut out, is particularly useful in the pumping product that tent to deform under load (pseudo plastic behavior).
The auger feed screw integrates a special device for joint protection.

Variants

DHSB 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.

JHSB 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 DHSB series. Represents the state of the art in this type of installation.
