PRO Shaft Seal 1-3/4" Shaft & 3" Tube

The PSS PRO Shaft Seal is a mechanical face seal utilizing our proven stainless steel and carbon sealing components but adds reinforced silicone bellows, a secondary shaft retention collar, 316 Stainless Steel hose clamps (rolled edges and non-perforated), and an optional Nitronic 50 rotor upgrade (for highly corrosive environments). Designed specifically for applications that will require increased durability and resistance to harsh, corrosive, high pressure, and otherwise demanding environments. The PSS PRO Shaft Seal is a specialized mechanical seal suitable for various applications, with unmatched performance.

As with PSS Type A & B Seals, The PRO Shaft Seal is a mechanical face seal. The sealing surface is created between the flat surfaces of the rotating stainless-steel rotor and the stationary carbon flange. The stationary carbon flange is attached to a heavy-duty silicone bellows attached to the vessel’s stern tube (shaft log), with 316SS hose clamps. The stainless-steel rotor is fitted on the shaft in front of the carbon flange and is used to compress the bellows, the rotor is then secured to the shaft with set screws, and the shaft retention collar is installed. This compression (pre-load) maintains constant contact between the two mating faces of the stainless-steel rotor and carbon flange, allowing the PSS to compensate for the variable axial movement due to propeller thrust. In addition, the carbon flange is over-bored to the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration from the drive-line. The stainless-steel rotor is sealed to the shaft by two O-rings recessed into the rotor's bore. These O-rings rotate with the shaft and the stainless-steel rotor and therefore do not experience wear during operation.

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love. I can’t wait to read the next one and to complete the series.

Unexpectedly emotional and packed with action!
Format: Kindle
Why do I suddenly want nothing more than a tiny wyvern to snuggle with?! It’s adorable and I absolutely love all of those moments! Wings of Stars was everything I’ve come expect from this powerful author duo. The fact that it’s written by two different people is completely transparent to the reader and they’ve brought us another world and characters that we’re all emotionally connected to and fully invested in! The injustice that we see from Alfemir in the many forms in which it comes is infuriating and makes me desperate for the conclusion of the story so they can all get what’s coming to them! I love all the guys right now, with one exception, and if you’re read it, you know exactly who I’m talking about. Bastian is hilarious - he was the comedic relief through an otherwise quite serious story. My heart bleeds for him and I can’t wait to see how he progresses through the series. Parts of Wings of Stars were unexpectedly emotional and of course I was left with my jaw on the floor at that cliffhanger! Next, please!

Niz !!!
Format: Kindle
First, let me say that I love both of these authors. I have been hooked by both ever since I discovered their writings, and I follow their social media groups closely. This book did not disappoint. Sure, there are several questions that I have, a couple of times I went huh (which I won't get into because I do not want to offer any spoilers) and I hated the cliff hanger lol, but I cannot lie and say I didn't love the book, because I did. The twist on angels was new and fresh, even though that is part of my questions. The beginning and ending were the better parts, the middle was needed but sorta bogged a little. Kieran was confusing but relatable. Niz is BY FAR the best character of the book, love NIZ. For me, Bastian is a close second, always loved the crazy ones. The other men were good, but Steele gets on my nerves and as of right now, IMO, he doesn't belong, but we will see how that goes. I have lots of questions, but this was an excellent start to a new series and I cannot wait for the next book. Highly recommend

fallen destiny? more like destined to fall in love
Format: Kindle
Kieran is an angel, but she doesn't have an affinity. Nothing angers her father more. If she doesn't find an affinity soon she will be cast to earth & have her wings removed. But she has the choice to become a fallen angel, wings turn black, & live her life on edge. Towards the end of the book things start to make sense. Gabe’s nickname for Kieran, Steele’a hatred, Bastian’s belief that Kieran is powerful. This book ended literally during a war? As one of her friends was injured, and admitted a bit secret? Talk about cliff hanger. The next book comes out August 5th.

Well holy moly!
Format: Kindle
Holy moly that story definitely had me hooked! Kieran was definitely a character that I immediately adored. She has obviously had to deal with a butt load of too high expectations from her father (who is 🤬).. She has been helpless when it came to finding out her affinity with so many years of no answers & perceived failure. When Ronan, gives her a small inkling of hope that she be a Beast Tamer, she jumps into it. But again she doesn’t seem to fit. But when she runs into Gabe again, she ends up helping him & rethinking her life in Alfemir. And when the opportunity comes she decides leaving is the best option. But when Ronan demands he comes with her & then the random appearance of Bastian, she is feeling very overwhelmed. After she chooses to fall with them, they land on earth exactly where Gabe is located only to run into Steele who is a person that I was finding hard to like. After training, she eventually finds out she does have an affinity & it’s one that no longer exist & is incredibly powerful but also has a prophecy attached to it. I feel incredibly bad for her on she learns about the prophecy & Steele’s connection with it too. But that ending, with the battle scene & Niz….yeah definitely was not expecting that but hello I am all here for it too! Absolutely amazing start of a series & I for sure will be waiting for the next one to come out. Amazing job!
