From what I've been told the pressure at -5000' will be about 15% higher than it would above sea level. I also found out from another source that the depth below sea level (not under water) will be the inverse of above sea level. Also that the temperature below will increase (if not cooled)...

I'm used to pumping above sea level but I was called and asked a question what are some of the affects that would come into play at 5000' below sea level. In a mine. Do you have to do anything special. Special pressure gauges? Motor problems to contend with or what? Thanks

MARC, Thanks I've contacted them - They are in England and I'm here in the Mid-West so I shall see if they have a representative and supplier here stateside. Appreciate your help. Wayne wlovison@toyopumps.com

Poppeye, I'm impressed and very well said. I agree with you 100% packing has always been a nitemare but compared to mechanical seals the cost savings is tremendous. Split seals are OK but have speed restrictions and when the pump is being overhauled don't install the split faces buy the...

I need a list of supplier's of pump pontoon manufacturers I need to get some quotes for some applications and its been difficult to get anyone to quote a job without being paid first? Can any of you help? Normally all I need is to send the weight of the pump and a dimensional data sheet and...

I read a note where a guy said his motor was waxed over? What does this term mean? Thanks wlovison@toyopumps.com

Corypad, Years ago I mean at least 35 years ago - I once worked for a nut and bolt company that made hardware from powder. I think the material was a brass or bronze nut/bolt. I was surprised too when I got there. I loved that job so much I quit after two weeks. wlovison@toyopumps.com

jbartos, Clarification: As stated the motor would never really run much into the service factor other than maybe a short start up event. The basic amp draw on the system is only 38 amps. The service is there only to protect a slightly higher fluid temperature. We buy many motors with 1.35...

We have a customer who has a 50HP motor installed already. We have an application that calls for a 75HP motor will this require new starters? Thought! What about motor's that are purchased 50HP with a 1.35 SF will the original motor starter be acceptable? Thought! If you install 75HP motor...

Last person who called me said he picked heaters by taking the FLA of the motor and adding in the service factor. Now that sounds find - but what about Starting Amps how does the heater compensate for that in rush and not blow? Simple I know but a simple answer will make me more informed in...

Sorry I ment Denver Wayne wlovison@toyopumps.com

Looking for a copy of File No. D-100 on Desity Data, Slury Water and Solids Pulp. Last Issue I have in very poor shape and is a 60th generation (very blurry) 8-1-72. Any help on where I can download a new fresh copy would be appreciated. Thanks Wayne wlovison@toyopumps.com...

Let's assume I have three identical pumps but all operating at three different speeds. 1620 RPM, 1080 RPM and a low one at 360 RPM. I'm sure I could belt drive the upper two but the lowest one the drive would be odd looking and expensive. Should I consider going to a 1200 RPM on the lowest...

We have some E310-15 rod is it ok to use? What does the 15 represent? Thanks Wayne E. Lovison service-parts@naglepumps.com

It's a 10" centrifugal pump single suction with an enclosed impeller design. It's rated 5000 USGPM @ 180' TDH. The product is waster water with a 1.05 gravity and 100 Deg. F pumping temperature. The motor is an inline 400HP @ 1200 RPM. The suction is flooded and the liquid is in a tank...

We have a customer who did not follow Hydraulic Institute Standards for having a suitable length of horizontal straight run pipe prior to the suction inlet of the pump. Therefore we are getting vortexing or a non-streamlined entry into the pump which sounds like cavitation or a crackling sound...

According to MG 1-1998 part 31 section 31.3.7 the service factor on the nameplate will be 1.0. The motor mfg. (Baldor) say's they don't nameplate the motor inverter duty. They got the spec and it called for a 1.15 service factor plus the abilty to operate with a VFD. They came back quoted a...

I have a 50HP 1775 RPM horizontal motor with Class H insulation. The motor nameplate is marked with a 1.0 S.F. No where on the motor does it say its inverter duty designed. But according to MG-1 Section 31 no inverter duty motor will have anything but a 1.0 service factor on the nameplate...

The question is pretty cut a dry but I've always wondered why enclosed motor's such as these would not require a space heater to prevent possible condensation from forming within the motor core and stator areas? Wayne E. Lovison service-parts@naglepumps.com
