Required Minimum Distribution (RMD) The IRS requires that you withdraw at least a minimum amount - known as a Required Minimum Distribution - from some types of retirement accounts annually, starting the year you turn age 70-1/2. Determining how much you are required to withdraw is an important issue in retirement planning.
There are two types of seals: the earless, or true, seals (family Phocidae); and the eared seals (family Otariidae), which comprise the sea lions and fur seals. In addition to the presence of external ears, eared seals have longer flippers than do earless seals.
Before I go on, Iâd like to explain two things. First, there are different types of dripless shaft seals â lip seals and face seals. The PSS one Iâm recommending is considered a face seal, which mechanically mates two smooth surfaces together by compression.y second point is that I donât want you to think that by installing a dripless shaft seal it means that it is completely maintenance-free. Itâs a boat, so nothing is maintenance free, but these seals do require less maintenance than stuffing boxes, and they reduce shaft wear.
