We have worked with and or installed over 45 pumice machines throughout the world with the majority of those being I.S. units . To add further credence to the argument the units are well constructed. The rinse is marginal at best and at the least a low pressure alarm is needed to prevent the carry over of pumice into subsequent processes. The addition of an auxiliary rinse is an excellent suggestion and the High pressure system from IS is quite frankly not as robust as the rest of the unit. There are some major wear items if proper shutdown and maintenance procedures are not followed, regular cleaning and lubrication of the drive chain and bearings is a must . Also the wash down of the bearings internally is extremely important . Lastly You will be far ahead of the game to set up and follow religiously a P.M. schedule ---------- From: Nelson, John To: [log in to unmask] Subject: Re: [TN] PUMICE SCRUBBER Date: Tuesday, January 12, 1999 7:56AM Priority: High In my 24 years I have worked with four IS pumice machines. They are durable as claimed. I recommend them as best in class. I would caution the buyer to not rely on their rinsing. The high pressure rinse system uses a noisy pump with seals that can blow out and soak the entire machine with oil. Don't buy that option. The remaining rinse systems are minimally effective. I recommend you install a triple sump, rinse and dry system after, maybe something from ASI or Chemcut or equivalent. ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
