New Maplenoll Ariadne owner needing advice

Threaders: Quite Pump Care (QP)

If you own a Maplenoll Quite Pump like is understandable you want to extend the life of the QP as long as possible.

Scott Leventhal includes some upgrade hose and fittings recommendations on his Tweak Sheet. Fotunately, the hoses and fittings on my QP are in excellent condition; The work been apparently done at the factory long ago.

However, besides implementing the QP recommendations mentioned earlier , I did a homework regarding the pump lubericant. The factory recommendated MOBIL 1 (5-30 SAE). Another synthetic alternative to Mobil 1 is AMSOIL 5W-30 SAE. The product has been extensively tested in racing circles and reportly outperforms all other syn. oils. I have used the product in my car for years so I decided to use the AMSOIL in the pump. After, the VERY messy job of clearing the pump of who's knows what via 17 years of faithful service;I replaced the oil, cleaned the pump, and replaced the filter. I then rechecked the pump for air leaks and gently retightened the clamps. The result ? A consistent air flow of not less than 45 PSI, a cooler and less noisey pump in operation. As always my results may not be your own , so you take your chances but for me no problems.

Air Supply Control:
Threaders; Using "hit an miss" , I have setteled upon a professional-type Air Control Unit I use to deliver a clean, oil free air supply from the Maplenoll Quiet Pump. The product , manufactured by Central Pneumatic, available at Harbor Freight , on-line or in their stores, # SKU 1118, consists of a air regulator, air control and filter unit. The specifications are ; operating pressure 160 PSI (Max.), Inlet size 1/2"NPT , Oultet size 1/4"NPT ( adapters/barbs required) , re-useable/ replaceable filter , Dimensions 11-3/4" Tall x 3-7/8" Dia. x 8-3/4" Deep , Weight 5-1/2 lbs., Filter up to 40 microns and Max.Capacity 21 C.F.M. @ 90 PSI. Sale Price $29.99. The Unit enters the air supply chain a few feet from the air output of the QT.

After the Air Control Unit, I follow-up with a secondary oil/water separator, a replaceable air filter , a charcole filter, a plenum (6"x41") that sends pressurized air to room where the 'Noll sits. At the 'Noll, all Walker Recommendations were implemented exactly as written with additional plenums/charcole filtering followed by 100' of tubing dedicated to the tone-arm . With the exception of a tweak here and there, the air supply chain is complete. More to come later.

Threaders: Air Supply Chain(ASC):
A odd thing happened following my last thread, the ASC started to spring leaks in places that already had been checked were ok. This is more challenging than I initially expected. Everthing in the air chain is going to be re-tested. I will keep you informed.

Threaders : Problems with Air Supply Chain (ASC) :

Specialists @ GE ( thread & PVC sealants ) report that for a variety of reasons the sealants I previously applied were not designed to work with PVC & metals . GE is forwarding industrial samples to apply. GE said that their products should seal the entire chain boosting the PSI . More to come soon.

Can anyone advise the air flow needed for the 70 pound platter model, I understand it should be 40-45psi pressure, but to size the compressor I need to know the flow/displacement in cfm.
Thanks.
James.
