The North Ridge DHSB/JHSB progressive cavity pump is installed with a customisable rectangular hopper that assists in feeding high viscosity fluids and dry products into the pump. This particular variation is installed with a separate motorised wheel and enlarged auger screw that enables it to handle fluids with up to 40% dry solids content. This series is excellent at pumping pseudo-plastic fluids and fluids that tend t plasticize.

There are two main versions of this progressive cavity pump series, each distinguished by how the motor is coupled to the pump. For the DHSB type, the motor is directly coupled to the pump to ensure a compact and easy maintenance design. The JHSB type is long coupled where a flexible coupling is installed between the pump and motor. The JHSB 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, minced meats, fruits and vegetables, paste, water treatment, industrial sludge, detergents, paper pulp, bio-waste, marine and agriculture.
