Abstract:
The present invention relates to positive displacement pumps, and particularly to diaphragm positive displacement pumps. An inventive diaphragm positive displacement pump is provided comprising at least one pumping chamber containing a deformable hose diaphragm, a working fluid cylinder fluidly connected to the deformable hose diaphragm, and at least one linear motor to displace the working fluid within the working fluid cylinder and thereby increase and decrease the volume of the pumping chamber. An inventive method of controlling an inventive diaphragm positive displacement pump comprising at least one pumping chamber and powered by at least one linear motor is also provided.
