These pressure batch mixers withstand up to 25 psi at ambient temperatures for closed-top tank applications. Once threaded or bolted to the drum or tank, the mixer prevents vapor loss, seals out dust and debris, protects motor from corrosive vapors, and eliminates contamination of batch solution from outside sources. Dry running, single lip seal is made of fluorocarbon polymer. All wetted parts are 316 stainless steel (SS). Radial deflection wear at seal is reduced by additional ball bearings located just above flange. Mixer flange (blind drilled and tapped) measures 6" OD and bolts to a mating 2", 150-lb ANSI nozzle-type tank flange with 4-3/4" diameter bolt circles. Requires four, 5/8" dia bolts and a 2" ID x 3-3/8" OD gasket (not included). New bung adapter mounting (on select models) allows mixer to be threaded into a 2" NPT bung.
Air-powered mixers feature needle valve for precise speed control and built-in muffler for quiet operation. We recommend using an air filter/regulator and an air lubricator with all air-powered mixers—order from 'Accessories'.
Air-powered mixers operate with air input into the 3⁄8" (10 mm) NPT(F) inlet port on the needle valve. All air motors require 60 to 75 max psig of air pressure. One-quarter and 1⁄3-hp air motors require an air flow rate of 15 scfm. One-half and 3⁄4-hp air motors require an air flow rate of 30 scfm.
