On-Site Assistance & Training

Jensen Mixers are designed to be serviced with basic mechanic tools — no special gauges, no proprietary equipment. Our on-site training programs ensure your maintenance team can perform every procedure correctly, safely, and efficiently.

Field Support from People Who Know Jensen Mixers

Northeast Controls Inc. has represented Jensen Mixers since 1973. Our team has supported Jensen mixer installations at refineries, pipeline terminals, petrochemical facilities, and bulk liquid storage operations throughout the northeastern United States for over 50 years.

We offer on-site training and field assistance for every aspect of Jensen mixer operation and maintenance — from initial installation through routine seal replacement, Petro-Block operation, Sentry System monitoring, and long-term preventive maintenance planning.

Jensen mixers are built to be maintained in the field by your own technicians. Our training programs give your team the knowledge and confidence to do exactly that.

Training Topics

Mechanical Seal Replacement

Hands-on training for the fastest seal replacement procedure in the petrochemical industry. Technicians learn the Jensen cartridge seal system, proper torque sequences, and how to verify correct installation — using only standard mechanic tools.

  • Cartridge seal removal and installation
  • Shaft lock-off procedure using Draw-Lock
  • Seal face inspection and cleaning
  • O-ring and spring replacement
  • Post-installation leak check

Petro-Block Operation & Reset

Training on the Petro-Block safety handle — how to activate it in an emergency, how to reset it during the standard lock-off procedure, and how to verify it is functioning correctly before returning the mixer to service.

  • Emergency activation procedure
  • Reset during lock-off
  • Functional verification
  • Integration with facility emergency response plans
  • OSHA LOTO coordination

Sentry System Inspection & Monitoring

Training on the Sentry Notification System — how to read the inspection ports, how to interpret fluid levels in the lube pod, and how to connect third-party electronic sensors for remote monitoring.

  • Lube pod fluid level inspection
  • Float ball and leak detection glass reading
  • Electronic sensor installation (1" NPT port)
  • Remote alert system integration
  • Drone inspection compatibility

Installation & Commissioning

On-site support for new mixer installations — from nozzle preparation and mixer mounting through initial startup, belt tensioning (Series 400/800), and operational verification.

  • Nozzle preparation and flange alignment
  • Mixer mounting and torque sequence
  • Belt tensioning and alignment (belt-drive models)
  • Motor coupling alignment (gear-drive models)
  • Initial startup and vibration check
  • Propeller roll-through via manway

Vari-Angle Adjustment & Maintenance

Training specific to Vari-Angle mixer models — how to safely adjust the entry angle while the tank is in service, how to inspect and maintain the ferrule seal and flex boot, and how to perform lock-off on a VA unit.

  • Safe angle adjustment procedure
  • Ferrule seal inspection and replacement
  • Flex boot inspection
  • VA ball stuffing box packing adjustment

  • Spare parts inventory guidance
  • Maintenance log documentation
  • Failure mode recognition

Training Formats

On-Site Classroom Training

Half-day or full-day

Instructor-led classroom sessions at your facility covering Jensen mixer theory, design features, safety systems, and maintenance procedures. Ideal for onboarding new maintenance technicians or refreshing existing crews.
