2VHL Continuum® Pumps are transfer pumps designed to handle a wide variety of fluids, with no operating noise. In few words transport and silence. The rotors of 2VHL Continuum® pump have been designed using the well known Continuum helical rotors, which are a byword for silence, energy consumption reduction and high performance.

The Continuum® concept, heart of 2VHL Continuum® pump, is based on three patented technological innovations:

• The rotors profile• The screw step• The inner force balancing

Three innovations that applied to the most advanced design and manufacturing capability of Settima, drive to a final results of a sustainable fluid power:

• Smooth changes in pressure growth• High efficiency• No noise• Energy consumption reduction

The standard housing sections of 2VHL Continuum® pump are made of grey cast iron, the helical rotors are manufactured with high strength hardened steel, located in a multi compound plain bearing bushes. Drive shaft is sealed by rotary shaft lip-type sealing.

2VHL Continuum® pumps are suitable for fluids with medium to high viscosity. 2VHL Continuum® Pump dimensions and flanges are similar to the standard gear pumps.

The specific configuration of 2VHL Continuum® pump, the high level of technology and the material used are the perfect combination for the last generation wind mills industry. 2VHL Continuum® pump means a long life as the wind mills industry requires.
