Multiple types of seals are offered. The Jensen Series 500 Mixer is the only side entry mixer designed for use in chemical service requiring 316SS corrosion resistant wetted metal parts. Every design feature is tailored to meet the rugged requirements of chemical plant and pipeline applications.
  • Jensen Mixers Series 600 Mixers are heavy-duty, gear driven mixers specifically designed for Petroleum Services. Maximum horsepower offered is 75. The Jensen Series 600 Mixer is the only side entry mixer designed exclusively for use in petroleum service. Every design feature is tailored to meet the rugged requirements of refinery and pipeline applications. In every horsepower range it offers superior life and load figures, unmatched ease of maintenance and outstanding mixing efficiency. ATEX certified.
  • Jensen Model 401 lease tank mixers offer bearings that are sealed and self-lubricating – this means no lubrication or maintenance for over 250,000 hours. The mixer is driven by a single adjustable V-belt.
  • General Notes on Series: All series focus on long bearing spans to prevent shaft whip, protective enclosures, and compatibility with accessories like vibration monitors. Vari-Angle models allow 60° angular adjustment for targeted cleaning. Fixed-Angle models are angled 7-10° for optimal swirl and turnover in blending.

Safety and Notification Systems

Jensen emphasizes environmental compliance and leak prevention through innovative systems:

  • First-Watch Notification System (for 600 Series):
  • Field-installable on older units; Monitors vibration and seal health.
  • Vibration: Murphy Mechanical Switch (customer-set levels); Electronic option with feedback/remote reset. Part Nos.: 620=95FY, 650=95FX, 680=95FW.
  • Seal Health: Thomas Products “Green/Red Light” float switch for visual alert; 1″ sight glass; Optional float/non-contact sensors for electronic monitoring.
  • Benefits: Customizable to operating needs; Simple, robust for changing environments.
  • Sentry Notification System (standard on new 450/480/800/900; retrofittable on existing 450/480 at factory):
  • Detects mechanical seal breaches; Externally-mounted lube pod holds tank pressure via gravity lubrication.
  • Visual float ball and leak detection glass; Compatible with third-party sensors/remote alerts.
  • Advantages: Environmentally safe, no power required, low maintenance, 12-month warranty; Prevents ground spills.
  • Petro-Block (standard on 800/900 Series):
  • Quick-activation handle pull stops leaks in seconds (99% effective); Contains product in tank.
  • Buys time for repairs, reduces manpower, enhances safety; Resets during lock-off.
  • Converts emergencies to minor issues.

Propellers and Accessories

  • Phoenix Propeller:
  • New design after 15 years of research, CFD modeling, and real-world testing.
  • Investment cast, dynamically balanced (ISO 1940-G6.3); Petrochemical-focused with variable pitch for efficiency.
  • Benefits: Optimized thrust/flow, improved efficiency/power utilization; Tailored pitch-to-diameter ratios per application.
  • Compatible across series; Made in USA.
  • Other Accessories:
  • Mechanical Seals: Cartridge design for quick change (under 5 steps); Backup O-ring minimizes loss.
  • Actuators: Mechanical (standard) or optional for Vari-Angle adjustment.
  • Couplings: Non-lubricated, flexible for misalignment; Easy removal without disturbing shafts.
  • Ferrule Seal: Teflon-impregnated, non-asbestos packing for Vari-Angle; Chemically inert, perfect fit.

Additional Key Points

  • Maintenance and Reliability: Fastest seal repairs in industry; All parts manufactured in-house (no discontinuations); Repairable with basic tools; Process recommendations guaranteed.
  • Applications: Primarily blending miscible fluids, sediment control, heat transfer; Operating procedures impact HP needs.
  • Warranties/Guarantees: 12 months on mixers/processes; Excludes certain wear items and third-party components like motors.
