Pump Technology
Pumps have been widely in use since the beginning of the industrial revolution, over 200 years ago. They are the second most common industrial device in the world today, the number 1, being the electric motor. Many experienced engineers are familiar with these traditional pumping technologies such as vane pumps, rotor /gear pumps, piston pumps and centrifugal pumps . SwashPump by contrast is an emerging transformational technology that supports the re engineering of many applications due to its superior performance characteristics.
SwashPump Operating Principles
 |
The Swash Plate nutates / wobbles / oscillates on a rotating slant shaft in the pumping chamber
NB; it does not rotate in the pumping chamber. It is stopped from rotating by a part we call the divider
|
 |
The Nutating motion is sinusoidal in nature. Given the Swashplate has two sides, there are two pumping chambers, each operating based on a sinusoidal rate of volumetric change, but 180 degrees out of phase |

It takes a full 720 degree rotation of the slant shaft for a complete intake and discharge of fluid. Watch the video and follow the red dash to study the unique swash pumping motion, in particular , follow where the red strip is throughout the process as this marks the sealing point between the high pressure and low pressure sides of the swash plate and pump body throughout a 360 degree shaft rotation |
