Abstract
A modular platen assembly comprises an annular hub, a wiper ring assembly and a coupling ring. The annular hub is for connecting to a ram of an inductor pump. The wiper ring assembly includes an annular wiper for sealing with a container. The coupling ring is independently joined to the hub and the wiper ring assembly at first and second connections, respectively.
Claims21
A modular platen assembly for use with a variety of containers, the modular platen assembly comprising:
- a hub comprising:
- an axial collar for connecting to a ram of an inductor pump;
- and
- a radial flange extending from the axial collar;
- a coupling ring connected to the radial flange on a surface facing axially away from the axial collar at a first connection and extending radially outward beyond the radial flange;
- a wiper ring assembly connected to the coupling ring on a surface facing axially toward the axial collar at a second connection independent of the first connection, the wiper ring assembly comprising:
- a wiper connected to the coupling ring at the second connection;
- and
- a cover coupled to the hub and the wiper ring assembly to cover the first connection and the second connection.
