Nova Rotors DHS-T - JHS-T Progressive Cavity Pump with hopper and liquid injection port - Solid Handling Apllication

Nova Rotors DHS-T/JHS-T Progressive Cavity Pump with Hopper and Liquid Injection port Flow RateUp to 600m³/hrHead (Pressure)Up to 48 barSizes AvailableFrom 025 to 300Operating Temperature-40°C to 150°CViscosityUp to 1,000,000cpDrive OptionsElectric Motor, Hydraulic Motor The Nova Rotors DHS-T/JHS-T progressive cavity pump is specifically designed for the biogas sector and pumping silage. It is fitted with a rectangular hopper that feeds high viscosity and dry products into the pump. The hopper length is customisable depending on the application requirements. The DHS-T/JHS-T range is fitted with an enlarged auger screw within the hopper that is driven by the motor, it rotates and helps the product flow into the pump to ease the pumping process. In addition to this, a liquid injection port is fitted after the hopper and before the pump to ease high viscosity dry matter into the pump. There is a rectangular bottom that collects any stones to stop these from entering and damaging the pump. There is a large inspection port with quick couplings that allow the easy removal of unwanted solids from the inlet. There are two main versions of this progressive cavity pump series, each distinguished by how the motor is coupled to the pump. For the DHS-T type, the motor is directly coupled to the pump to ensure a compact and easy maintenance design. The JHS-T type is long coupled where a flexible coupling is installed between the pump and motor. The JHS-T type is more robust as all the forces during pumping are absorbed by the bearing housing rather than the motor. The casing of this positive displacement pump can be constructed from various materials including cast iron, stainless steel 304, stainless steel 316 and duplex stainless steel. The rotor is available in stainless steel 420, 304, 316 and duplex, while the stator can be supplied in NBR, EPDM, FPM, HNBR, Hypalon and PTFE. Such a wide range of material choices makes this pump series extremely versatile and capable of pumping a vast range of fluids. Sealing options for this helical rotor pump include gland packing, gland packing with flushing, single mechanical seal, single mechanical seal with quench, double mechanical seal, single or double cartridge seals and API rated sealing systems. This progressive cavity pump is Atex certified for handling flammable fluids and installation in non-safe areas. API 676 certification is also available if required. This progressive cavity pump is ideal for many applications in the industrial and marine markets, including; sewage sludge, dehydrated sludge, fish waste, paste, water treatment, industrial sludge, detergents, paper pulp, bio-waste, marine and agriculture.
