rtshfd Posted June 16, 2015 Share Posted June 16, 2015 What style pump is everyone using for low wines? Link to comment Share on other sites More sharing options...
John McKee Posted June 17, 2015 Share Posted June 17, 2015 Air Operated Diaphragm pump Centrifugal pump with TEFC or XP motor and starter Moyno Progressive cavity pump with TEFC or XP motor and starter Used them all. AOD is the safest, easiest (self priming), pump to use...I highly recommend going that route. Link to comment Share on other sites More sharing options...
captnKB Posted June 17, 2015 Share Posted June 17, 2015 We use a flex impeller pump similar to this https://store.tcwequipment.com/products/jabsco-sqn-50-flexible-impeller-pump Link to comment Share on other sites More sharing options...
Michaelangelo Posted June 22, 2015 Share Posted June 22, 2015 captnKB....you are using this for low wines? Link to comment Share on other sites More sharing options...
Glowe8 Posted June 25, 2015 Share Posted June 25, 2015 We use an AOD as well. Stainless body and ethanol capable diaphragm material. I would also suggest that route. Link to comment Share on other sites More sharing options...
captnKB Posted June 27, 2015 Share Posted June 27, 2015 yes we are using our flex impeller but only if the low wines are under 100 proof. if over 100 proof we use air diaphram pump Link to comment Share on other sites More sharing options...
MichaelAtTCW Posted July 7, 2015 Share Posted July 7, 2015 The SQN 50 flex impeller pump that captnKB linked can definitely pump low wines, and as folks have said, for higher-proof spirits the best two options are to go with an air diaphragm pump or a flex impeller pump with XP motor and starter or VFD. We've done a few XP flex impeller pumps for high-end distilleries, but the price makes them prohibitive for startups, particularly if you add a VFD for speed control: Jabsco SQN 50 XP Those XP-rated components can get pricey. The constantly-purged stainless steel enclosure looks pretty damn cool, though Link to comment Share on other sites More sharing options...
John McKee Posted July 7, 2015 Share Posted July 7, 2015 Michael, You can also get the Flex Impeller pumps with air operated motors correct? In which case, XP wouldn't be a concern. Nice option for some. Cheers, McKee Link to comment Share on other sites More sharing options...

Nice option for some. Cheers, McKee Hi McKee, Yep, you could use a pneumatic motor to power a flexible impeller pump. Generally speaking air diaphragm pumps are able to run more efficiently given the same PSI/CFM of air input. Flexible impeller pumps need a lot of torque to start rotating the impellers, particularly when they're priming, and a lot of torque to reverse the direction of the impellers. Pneumatic motors have a harder time providing the necessary torque without a big compressor backing them up. Electric motors and VFDs, on the other hand, can provide high torque and RPMs relatively easily. The cost of an electric motor that provides the necessary torque to turn a large impeller is hundreds of dollars. The cost of a compressor to provide the same torque to a pneumatic motor is thousands of dollars. I'm sure there's a sweet spot, and we're looking for it.

david_october Posted July 9, 2015 Share Posted July 9, 2015 We do a pump cart like enclosed file for our clients for their winery. The pump are of stainless steel, explosion-proof and sanitary grade. Link to comment Share on other sites More sharing options...
