Main Pump (Denison T6DMY Series)
Flex Side Plate Operation
The flex side plates for both inlet and outlet are symmetrical. Pressure is fed behind each side plate into
two kidney shaped cavities which are sealed by special seal packs. The two flex side plates and their
associated kidney shaped cavities function in the following manner. As pressure builds up in the outlet,
pressure also builds up in the cavities. The pressure in the cavities hold the flex side plates in hydrostatic
balance against the rotor and provide optimum running clearances for minimum internal leakage and
minimum friction (See Figure 5).
The flex side plates also provide passages for feeding under vane pressure to the space between the vane
and insert.
The bronze faces of the flex side plates ride next to the rotor and provide excellent wear and cold start
characteristics.
The inlet and outlet support plates hold the flex side plates in position and contain passages which allow
fluid to pass from the inlet to the pumping cartridge and from the cartridge to the outlet port.
