Preston Variable Flow Pump, 2-5000ml/Minute. Manostat
The Preston produces variable flow rate from 2 ml/min to 5000 ml/min. All models have a separate precision digital speed and lighted on/off switch. The on/off switch lets you maintain your flow rate setting when pump is turned off. Each model is reversible for purging of transfer lines. The 1/10 hp reversible motor has soft start and back EMF for 3% speed control. All drives come complete with pump head and tubing link. The chemically-resistant pump head (molded of glass filled Noryl®)[…] Barnant
E Series Peristaltic Pumps. Manostat
Economical and compact peristaltic pumps provide a constant flow of liquids or gases at a fixed rate. Four factory-pre-set RPM pumps are available and four different silicone tubing I.D.'s can be used in each pump to obtain different flow rates. The self-priming pump head is made of molded polypropylene and has two rollers. Unit will work against back pressure up to 25 PSI continuous and 40 PSI intermittent, making it ideal for filtration applications and for work with viscous fluids.[…] Barnant
Vacuum-Pressure Pump, 20" Hg/18 Psig. Barnant
For use in either high-flow or low-flow applications, these corrosion-resistant pumps offer vacuum to 20" Hg, pressure to 18 psig, free-air capacity of 1100 cu in./min, a small compact size and no oil to contaminate flow. Non-contaminating engineered plastic construction-gas contacts only the Noryl or Valox body, nitrile and Fluorel diaphragm and PTFE valves. All-plastic head; no metal in contact with gas flow. Service-free motor-brushless motor with sealed ball bearings and thermal[…] Barnant
Dual Head Vacuum-Pressure Pump
Air Cadet Dual-head Vacuum-Pressure Pump offers you increased capacity over the single-head Air Cadet pump. Creates 20" Hg of vacuum and 18 psi. Use the two pump heads independently or connect them in series with 3⁄8" ID Tygon® vacuum tubing for up to 23" Hg vacuum. Compact size makes pump ideal for portable applications. All-plastic, convoluted diaphragm design handles many vacuum/pressure applications and reduces stress, wear, and heat build-up. Caution: Do not use metal[…] Barnant
Vacuum-Pressure Station
Vacuum/Pressure Station features a built-in bronze and brass vacuum/pressure gauge and stainless steel (SS) regulator. Creates 20" Hg of vacuum and 18 psi. Compact size makes pump ideal for portable applications. All-plastic, convoluted diaphragm design handles many vacuum/pressure applications and reduces stress, wear, and heat build-up. Caution: Do not use metal fittings with any Air Cadet pump. Use the auxiliary port to evacuate or pressurize two systems simultaneously. Station includes[…] Barnant

This solid-state controller provides exact speed setting within its 20:1 speed adjustment range. Potentiometer controls both on/off and variable speed[…] Barnant
General Purpose Dual-Shaft Mixer. Barnant
This versatile, dual-shaft allows both high-speed and high-torque mixing in either small or large volumes. Use the direct-drive shaft for your high-speed, low-viscosity mixing, or just switch to the gear-reduction shaft for your high-viscosity mixing needs. Direct-drive shaft offers high speeds from 50 to 5000 rpm with 7in-oz torque. Gear-reduction shaft provides high 140 in-oz torque from 3 to 250 rpm. 1/25 hp motor. Solid-state controller offers precise speed control with a 100:1[…] Barnant
Heavy-Duty Modular Mixing Systems. Barnant
Barnant's modular heavy-duty mixer system allows you the flexibility to create the best system for your mixing applications. System components are sold separately so you can tailor your system to meet your mixing needs. Simply start with a solid-state speed controller, add one of the four mixing heads depending on your speed and torque requirements, and select a shaft and propeller depending on your vessel and fluid. For the full line of Barnant shafts and propellers, see S5470-S5473.[…] Barnant

Simply start with the new mixer controller, add one of the four mixing heads depending on your speed[…] Barnant
Barnant Stainless Steel Paddle Assemblies.
Use these 316 stainless steel paddle assemblies for appropriate applications with regard to chemical resistance and shaft diameter. Barnant
Barnant Coated Paddle Assemblies
Use these plastic paddle assemblies for mixing most acids and corrosive solutions. Plastic-coated steel assemblies provide better chemical resistance than stainless steel alone. Choose from three plastics according to the chemical compatibility of your solutions; polypropylene, polyethylene or Teflon PTFE. All shafts are 5/16" in diameter. Barnant
Barnant Stainless Steel Propellers
These propellers are made of 316 stainless steel. Barnant
Barnant Stainless Steel Stirring Shafts
These shafts are constructed of 316 stainless steel. The 3/8" diameter shafts are machined on one end to also accept 5/16" bore diameter propellers. Barnant
Barnant Mixer Accessories
Mount your mixing system directly onto an open top tank or container. Clamp secures a mixer head and the S5473-3 pivot mount controller support sold below. Mounts to containers with wall thicknesses up to 1-1/2. Controller supports let you mount your controller adjacent to the mixer head. Use the dual rod clamp (included in the S5474-2) to secure your controller to the S5473-4 (support stand). Or mount our S5473-3 mount support directly to the S5473-1 tank clamp. Barnant
Manosil™ Silicone Tubing
