Which of the listed parts is used in a lobe-type rotary pump to allow for wear on the lobe edges?

ASpur gear adjusters
BReplaceable liner plates
CCasing gear thrust bearings
DReplaceable gib inserts
AI Explanation

The correct answer is D) Replaceable gib inserts. In a lobe-type rotary pump, the replaceable gib inserts allow for wear on the lobe edges over time. As the lobes wear down, the gib inserts can be replaced to maintain the proper clearance and seal between the lobes, ensuring efficient pump operation. The other options, such as spur gear adjusters, liner plates, and casing gear thrust bearings, are not specifically designed to accommodate wear on the lobe edges in a lobe-type rotary pump.
