🔍 Key Concepts

• Identify the type of pump shown (note the rotating vanes and liquid ring). • Trace the flow path of gas versus the sealing liquid through this style of pump. • Relate where shaft support and packing would normally be located in any rotary pump.

💭 Think About

• Look closely at where label C is pointing: is it on the shaft, on the casing, or on an opening/port in the port plate? • Ask yourself which part of this pump would reasonably serve as a path for gas flow, and which parts would more likely deal with shaft support or sealing. • Compare the shapes and positions of all openings: which look like inlets/outlets, and which look like simple clearances or supports?

✅ Before You Answer

• Confirm whether C points to a port/opening** or to a solid bearing/shaft area. • Check if a bearing surface would normally be located on the rotating shaft or in the end housing, not in the vane chamber itself. • Verify that packing or mechanical seals are placed where the shaft exits the casing, not out in the middle of the pumping chamber.
