High-Efficiency Impellers to Match Your Process Needs

A510: General Purpose

New laser-designed impeller delivers true axial flow, high flow-per-horsepower, and can be custom-fit to your application.

A315: Gas-Liquids-Solids

Improves yield by up to 50% in shear-sensitive processes such as fermentation. The A315 is the optimum impeller for applications involving mass transfer and solids suspension.

A320: High-Viscosity

Fluid foil design reduces blend time by half and delivers better axial motion for 50% power saving compared to conventional pitch-blade turbines.

A6000: Low Viscosity

For flow-controlled applications in hostile environments. Maintains flow and reduces power to 45% of conventional pitched-blade impellers. Structural composite is lightweight and-extremely resistant to corrosion.

LightninLube™

As part of our commitment to our Customers and their operations, SPX FLOW has introduced LightninLube™, a range of gear oil for our Lightnin Mixers. It is available to order withyour new equipment or as a maintenance item throughout the life of your equipment. LightninLube is manufactured to AGMA Standard 8005-D94. Our synthetic oils are designed to give you a wide operating range and are available in ISO 100, ISO 150, ISO220 and ISO 320 grades. Contact our Service department or your Sales Representative to discuss your needs.

The Biggest, Heaviest Duty Standard Drives Made Specifically for Mixing

The 700/800 series has the capacity to drive long overhung mixer shafts without steady bearings. It has the stamina to withstand severe bending and high-torque loads imposed by fluid forces in the tank. Shafts for 700/800 mixers are larger and stronger. The bearings are sized far in excess of AGMA requirements. Extensive research is conducted to document the limits of shaft and impeller performance under all service conditions.

As a result, you get longer service life with less maintenance. You get our performance guarantee.

You get a mixer with an enviable track record, written by the thousands of 700/800 mixers produced in our state-of the-art plant. You’ll find our 700/800 mixers atop huge fermentation tanks in pharmaceutical production and in all manners of large scale chemical processing. You’ll also find them in the dust and rock of minerals processing,as well as in the heavy sludge of waste treatment.
