INKOMA SSP series stainless steel worm gear screw jacks are entirely new and manufactured specifically for the harsh requirements of modern paper machines and similar corrosive environments. The SSP is based on a standard kit, which can be mechanically coupled to create an array to achieve required overall system capacity. The SSP is also very suitable for food processing industries, explosion proof areas, chemical and petroleum refining plants.
