Series 800/900

Jensen Series 800/900 Belt & Gear Driven Side-Entry Mixers

Jensen Mixers. Simple. Logical. Fast.

These characteristics are commonly associated with Jensen Mixers' designs. Jensen Mixers has a reputation for providing the FASTEST mechanical seal repair process in the petrochemical industry. The new 800 & 900 Series mixers uphold the same design concepts that have been respected by technicians for decades, but Jensen made the process even simpler with the introduction of the Draw-Lock. With the turn of an Allen wrench, the Draw-Lock mechanism makes the lock-off procedure safer and more convenient. And now that Jensen Mixers has incorporated a DOUBLE MECHANICAL SEAL into the designs, the Jensen 800 & 900 Series mixers are the most advanced side-entry mixers available today!

Jensen is changing the industry. Again.
Over 70 years ago, Jensen Mixers built the first side-entry mixer, creating an entirely new industry. Other companies have tried to mimic these products, but Jensen's mixers are consistently built the toughest and are the simplest and quickest to repair. The 800 & 900 Series mixers stay true to those values in bigger and better ways, with new added safety standards and improved performance.
