Filter Drive
Permitting the latest drive technology to be designed or retrofitted into the system, the top mounted drive assembly can be easily removed from the vessel.
options include

hydraulic drive directly coupled to the filter shaft.
Electric Drive with reducer or belt-and-pulley arrangement
Variable speed drive systems

Upper Seal & Bearing Assembly
Designed to eliminate causes of failure, the seal rides on a bearing sleeve instead of the shaft, preventing shaft wear and the potential for costly repair. Since the main bearing which supports the filter nest is separated from the seal, the potential for the main bearing to fail due to a leak is eliminated, unlike bottom drive systems. Seal options include

lip seals
stuffing box with or without flushing
mechanical seal
hydraulic bellows seals.

Filter Plates
Dished filter plates with spacer rings and sealing gaskets are mounted on a hollow shaft, and secured by a tightening devise. The filter media is held in place by a clamp ring and can be quickly and easily changed. Various types of filter media are available.
Lower Bearing and Seal Assembly
Unlike bottom drive systems with proprietary seals, all seals are standard components, proven reliable in years of operation.

Rotating bearing and seal connected to the filter shaft, with spigot mounted on a bearing support inside the filter vessel. Available on type R filters
Choice of materials for bearing bushing-such as filled teflon or other machined plastics-with lip seals on both sides. On Type R filters a Teflon sleeve Below the bearing bushing assures highest filtrate purity
