An improved drive seal arrangement for a dry good material feeder includes an auger member which is provided with a helical flight that extends into the space proximate the drive shaft seal so as to create an underpressure proximate the seal and keep the dry material which is to be conveyed away from the seal. A novel shaft connecting linkage is further provided to isolate the seal from vibration or shock which is imparted to the drive auger during operation. A novel modular construction is also provided whereby the hopper and auger member may be dismounted from a power unit, which slides into the hopper as a single module so as not to affect the drive shaft seal.
