<p>A cooling arrangement is provided for the sealing members of a plastic bodied pump. The cooling arrangement comprises a metal cup-shaped member which is mounted to the pump housing to hold a stationary member of the seal. The metal member is exposed to the dry side of the seal and surrounds the drive shaft. A flinger, which may take the form of a disk, is carried on the shaft on the dry side of the seal closely adjacent to the exposed portion of the metal member to provide a localized air flow to assist in the cooling of the metal member, and thus, the seal members.</p> |
