Features & Innovations

Innovations that set Jensen apart — built to keep plants and workers safe since 1950

When A.C. Jensen designed the first side-entry mixer, he addressed specific application challenges he had experienced working in the petroleum industry — most importantly, worker safety. He pioneered the vari-angle (swivel) design and pitch-adjusted propellers that have set Jensen apart from the competition for over 70 years.

As Jensen's mixers have evolved, key features like Petro-Block, the Phoenix Propeller, Sentry Notification System, and First-Watch have been incorporated — not only built to last and easy to maintain, but the most advanced mixers on the market today.

Jensen Innovations

Petro-Block

See a leak. Pull the handle. Plan the repair.

Standard — 800 & 900 Series

Requiring only seconds to activate, the Petro-Block is 99% effective in keeping product where it belongs — in the tank. A simple pull of the handle stops the flow of tank fluid immediately. The system resets during the standard lock-off procedure, converting emergency repairs into minor inconveniences.

  • Activates in seconds — no tools required
  • 99% effective at containing tank fluid
  • Resets during standard lock-off procedure
  • Creates new levels of safety and convenience for field crews
Jensen Phoenix Propeller — investment cast, dynamically balanced

Phoenix Propeller

Improved efficiency. Optimized thrust. Focused petrochemical performance.

Standard — All Series

Developed with 15 years of research and real-world testing, the Phoenix Propeller is designed specifically for petrochemical applications. Each propeller is size and pitch-adjusted to match the specific application's pitch-to-diameter ratio, maximizing performance and power utilization.

  • Size and pitch-adjusted per application
  • Dynamically balanced to ISO 1940-G6.3 scale
  • Cutting-edge manufacturing techniques
  • 15 years of research and real-world testing

Sentry Notification System

Contain the leak. Alert the team. Protect the site.

Standard — 400 & 800/900 Series

The Sentry Notification System buys you time before leaks spill on the ground. It allows for early and temporary tank product containment in the event of a mechanical seal breach, preventing tank contents from reaching the ground and giving your team time to respond.

  • Early and temporary tank product containment
  • Prevents tank contents from leaking onto the ground
  • Fitted with inspection ports
  • Optional electronic sensors available

First-Watch Notification System

Warns you of a leak before it becomes a problem.

Standard — 600 Series

The First-Watch system gives you time to react when a mixer seal needs attention. Three inspection ports allow technicians and drones to visually monitor levels easily. The bottom port displays seal lubrication fluid and any invading tank contents. The middle port is designed with a 1" NPT for mounting electronic sensors.

  • Three inspection ports for visual monitoring
  • Bottom port shows seal lubrication and tank intrusion
  • Middle port: 1" NPT for electronic sensors
  • Compatible with drone inspection

Draw-Lock

Simple, logical, and fast.

Standard — 800 & 900 Series

The Draw-Lock was introduced to make Jensen's already-fast lock-off procedures even easier. A simple turn of an Allen wrench completes the lock-off, furthering Jensen's reputation for user-friendly maintenance procedures.

  • Single Allen wrench operation
  • Faster and safer than previous designs
  • Reduces time spent on lock-off procedures
  • Consistent with Jensen's ease-of-maintenance philosophy

Variable Angle (Swivel) Design

Pioneered by Jensen — still unmatched.

Available — All Series

A.C. Jensen pioneered the vari-angle (swivel) design over 70 years ago to address specific application challenges in the petroleum industry. The ability to adjust the mixer angle allows operators to optimize mixing patterns for different tank geometries and fluid conditions. A mechanical actuator is available as an option on swivel angle designs.

  • Adjustable angle for optimized mixing patterns
  • Fixed and swivel designs available on all series
  • Mechanical actuator option on swivel designs
  • Pioneered by Jensen over 70 years ago
