Re: [biofuel] mixing pumps
wouldn't, totally enclosed, fan cooled be an oxymoron? Paul, I don't think so. An external fan can either pull in cooling air or displace radiant heat. It's the actual electric works of the motor (rotor, windings, brushes) that are encapsulated (totally enclosed) isolating any spark source from the external atmosphere.

Re: [biofuel] mixing pumps
I stand corrected there Todd, got to thinking after I made that post. As you say a motor in a finned encapsulated case wth a fan on the dead end of the output shaft flowing air through the fins would qualify. - Original Message - From: Appal Energy [EMAIL PROTECTED] To: biofuel@yahoogroups.com Sent: Tuesday, September 02, 2003 2:20 AM Subject: Re: [biofuel] mixing pumps wouldn't, totally enclosed, fan cooled be an oxymoron?

[biofuel] mixing pumps
Wondering if anyone can help me with this one. I am trying to source a pump that can handle the whole mixing job for the methoxide. Presently I have to switch the portable mixer between the methoxide tank and the reaction tank and I also have to keep the lid to the methoxide tank open when mixing. I am mixing roughly 35 gallons of methanol with almost 4 kg of lye. Naturally, sonce the lye is at the bottom, the pump would have to be able to mix/grind/move that solid material along with the methanol until it dissolves completely (my pump draws out of the very bottom of the tank). I appreciate any recommendations.

Re: [biofuel] mixing pumps
Jack, The cheapest best method would be a magnetic drive pump, where you wouldn't need to be concerned about any loss of seals. The pump is magnetically driven, not mechanically. At minimum you would also want the drive motor enclosure to be TEFC, fan cooled, continuous duty and preferable thermal overload protected. March Manufacturing makes such pumps, with TEFC option starting with their Series 5. I'm none too sure whether Little Giant includes the totally enclosed option. You'll have to calculate the number of change overs you want in the tank per hour in order to size the pump. Both company's products should be readily available world wide. www.marchpump.com http://www.marchpump.com/pump.htm and www.littlegiant.com Todd Swearingen - Original Message - From: Jack Kenworthy [EMAIL PROTECTED] To: biofuel@yahoogroups.com Sent: Sunday, August 31, 2003 6:22 PM Subject: [biofuel] mixing pumps Wondering if anyone can help me with this one.
