The SOMA SINUS SODIAL Positive Displacement Pump works according the SOMA SINUS SODIAL® PUMP principle, which was developed by Manfred Sommer in 1982. This Sinus pump, available in long-coupled (CRN) and close-coupled versions (CRN-D), is distinguished by its extremely gentle pump action, powerful suction with low-shear and low pulsation. This pump can overcome the limitations of conventional rotary lobe pumps in many applications.
The Sinusoidal curve shaped rotor is fitted on a pump shaft. Due to the design, four chambers are created in which the product will be transferred very gently - without any shear or damage to the product. A scraper divides the suction and the pressure side. The rotor does not run against the housing or the cover. That means, that the housing and the cover will never wear out.
Perfect for low and high viscosity products
Uniform and almost pulsation-free delivery
Lifetime guarantee on housing and cover
