SOMA Sinusoidal Pumps

SOMA Sinusoidal Pumps

A positive displacement pump is able to discharge constant amounts of fluids with each revolution under almost all conditions, providing continuous flow. The Soma Pump is a positive displacement pump developed by Manfred Sommer in 1982, and incorporates a sinusoidal curve shaped rotor, mounted on one pump shaft with one seal system. Due to the design of this rotor, four chambers are created in which the product is transferred very gently – limiting shear while maintaining product integrity. It specializes in shear-sensitive and viscous applications with its powerful suction capabilities, spanning the food and beverage sanitary market across the globe.

A scraper gate surrounding the rotor provides the divide between the suction and the pressure side, the inlet and the outlet. The rotor does not run against the housing or the cover, as it sits in between liners that are replaced over time, meaning the housing has decades of staying power. In fact, SOMA Pumps GmbH offers a lifetime guarantee for the cover and the housing.

The stainless steel housing pump of SOMA is also very cost effective upfront, with lower costs initially than most pumps offering painted power frames. These stainless steel power frames come in a variety of sizes, orientations, and mating connections.

The SOMA pump parts are interchangeable with all sinusoidal positive displacement pumps, with a lower overall cost of ownership.

Frequently asked questions about pumps

What is a peristaltic pump?

A peristaltic pump is a type of positive displacement pump used for pumping a variety of fluids. Peristaltic pumps are also commonly known as roller pumps. The fluid is contained within a flexible tube fitted inside a circular pump casing.

What is a metering (or dosing) pump?

A metering pump, or dosing pump, moves a precise volume of liquid in a specified time period providing an accurate volumetric flow rate. Delivery of fluids in precise adjustable flow rates is sometimes called metering.

What is a positive displacement pump?

A positive displacement pump moves fluid by repeatedly enclosing a fixed volume and moving it mechanically through the system. The pumping action is cyclic and can be driven by pistons, screws, gears, rollers, diaphragms or vanes.

What is a sinusoidal pump?

A sinusoidal pump is a type of pump featuring a sine wave-shaped rotor that creates four moving chambers, which gently convey the duty fluid from the inlet port to the higher pressure discharge port.

What is a tube or hose pump?

Peristaltic pumps are usually connected with tubes and/or hose (depending on size.) Sometimes we refer to these as tube pumps or hose pumps.
