The NOVA ROTORS DHS-T and JHS-T Series screw pumps with hopper and feed screw for direct feeding of the product to the hydraulic part are the ideal solution for pumping viscous and non-flowing liquids with a high content of solid particles.
DHS-T and JHS-T Series with a rectangular version of the hopper with an enlarged hydraulic feed screw. A model specifically designed for the biogas silo pumping sector with liquid phase injection at the suction to improve solid particle pumping. A separate entrance provides a connection for injecting the liquid phase, and a rectangular bottom collects stones that can get inside the hopper and be transported by an auger. This avoids damage to the hydraulic part.
In addition, an additional wide and fast viewing hole is provided, which makes it easy to clean at the suction stage.
DHS-T Series: the drive connects directly to the pump via a flange. This solution is extremely cheap and compact, which significantly reduces installation costs and simplifies maintenance. The voltage generated by the hydraulic part is maintained by the drive itself.
Each drive used is selected accordingly, based on specific technical parameters and is subjected to numerous tests with heavy loads.
Applications: sewage sludge, water treatment, industrial sludge, detergents and Chemical Products, Paper Products, agriculture, petrochemical products, marine industry.
