The area on the figure that says front chamfer should be facing the sea water so that a higher external pressure causes the area around the garter spring to compress. When oil in the motor expands due to temperature, it is vented to the flexible bladder and not out past the lips seal. If bladder is soft, then the pressure inside the motor should be approximately the same as the ambient water pressure regardless of depth.</div><div id="yui_3_16_0_1_1432163484657_2709" dir="ltr"><br></div><div id="yui_3_16_0_1_1432163484657_2719" dir="ltr">For air compensation in which your regulator is set say 4 psi above ambient water pressure, then you would want to reverse the orientation of the lip seals so the higher internal pressure tends to tighten the seal.</div><div id="yui_3_16_0_1_1432163484657_2710" dir="ltr"><br></div><div id="yui_3_16_0_1_1432163484657_2727" dir="ltr">The lip seals on the MK101 come with the front chamfer faces the sea water.</div><div dir="ltr"><br></div><div id="yui_3_16_0_1_1432163484657_2744" dir="ltr">Got to run. </div><div id="yui_3_16_0_1_1432163484657_2728" dir="ltr"><br></div><div id="yui_3_16_0_1_1432163484657_2729" dir="ltr">Cliff<br><br></div><br> <div id="yui_3_16_0_1_1432163484657_2626" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px;"> <div id="yui_3_16_0_1_1432163484657_2625" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_1_1432163484657_2624" dir="ltr"> <hr size="1" id="yui_3_16_0_1_1432163484657_2702"> <font id="yui_3_16_0_1_1432163484657_2623" face="Arial" size="2"> <b><span style="font-weight: bold;">From:</span></b> Alan James via Personal_Submersibles <personal_submersibles@psubs.org><br> <b><span style="font-weight: bold;">To:</span></b> Personal Submersibles General Discussion <personal_submersibles@psubs.org> <br> <b><span style="font-weight: bold;">Sent:</span></b> Wednesday, May 20, 2015 4:49 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [PSUBS-MAILIST] Lip seal<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_1_1432163484657_2630"><br><div id="yiv0731404844"><div id="yui_3_16_0_1_1432163484657_2629"><div id="yui_3_16_0_1_1432163484657_2628" style="color: rgb(0, 0, 0); font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);"><div id="yiv0731404844yui_3_16_0_1_1432157578190_4700"><span id="yiv0731404844yui_3_16_0_1_1432157578190_4745">While on the motor subject; a simple low pressure lip seal as below (substitute air side with water side)</span></div><div id="yiv0731404844yui_3_16_0_1_1432157578190_4700"><span id="yiv0731404844yui_3_16_0_1_1432157578190_5089">will be pressure compensated in a compensated motor!
