Sinusoidal pumps
The SOMA SINUSOIDAL Positive Displacement Pump works according the Sinusoidal PUMP principle, which was developed by Manfred Sommer in 1982. 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. SOMA offers an unlimited guarantee for the cover and the housing. Various seal system can be offered such as – triple lip seal system or mechanical seal systems are available.

With the SCN-D series of the SOMA SINUS SODIAL® PUMP, SOMA PUMPS GmbH was the first to launch a new development on the market. The further development of the SOMA SINUS SODIAL® PUMP as a monobloc version is a SOMA PUMP, which does not require a bearing block, coupling and a complex base plate. In this version, the SOMA SINUS SODIAL® PUMP is therefore flanged directly to the drive.
This version is available in various sizes up to 40,000 l/h with a maximum counterpressure of 10 bar. A big advantage is that all wear parts of the pump are identical to the 15 bar version with bearing block. This means – no separate storage for the wear parts – 100% interchangeability between the variant with separate coupling and the directly flanged variant
Close Coupled 30% shorter overall Size 20% cost savings lower maintenance costs
