Calibration & Preventive Maintenance



Are you having inaccuracies with your batch weights?  Are batch temperatures drifting during the process?  The issues in your process may not always be mechanical.  It could be a calibration issue.

The importance of calibration, maintenance and repair programs cannot be overlooked in sanitary processing operations.  The cost of regular maintenance and repair is very small when compared to the cost of major equipment breakdowns and lost production.


Calibration is defined as the activity of checking, by comparison with a standard, the accuracy of an instrument.  It may also include adjustment of that instrument to bring it into alignment with the standard.

Instruments need to be calibrated on a regular schedule to:

  • Insure readings are consistent with other measurements
  • Determine the accuracy of the instrument
  • Establish the reliability of the instrument

Because M.G. Newell helps make it work better, we offer a variety of calibration services that keep your operations consistent and cost-effective. Hidden costs may be the extra gallons of fructose or glycerin through your meter or the down time added due to incorrect level sensors in your filler.

Calibration services are available at your location or in our Greensboro or Louisville shops.

  • Calibration Services For:
    • LEVEL
    • pH
    • FLOW including
      • Magnetic
      • Turbine

“The pumps rebuilt by M.G. Newell’s Pump Rebuild program give us better reliability than we get with new pumps.”Steve Semans, Sr. Procurement Specialist, ConAgra Foods
The Certified Repair Center program is designed to ensure that all repair work completed on-site meets the same standards that are in place at the SPX manufacturing facilities. Distributors are required to complete rigorous program requirements, including:

  • Passage of in-depth, hands-on product training
  • Purchase of specialty tools required for maintenance
  • Maintain inventory levels of spare parts
  • Pass an annual audit to verify all the items above
Our Certified Repair Centers in Greensboro, NC, Louisville, KY and Nashville, TN provide significant benefits to our customer base:

  • Reduced cost of product ownership
  • Minimized shipping expenses
  • Increased product uptime
  • Expedited warranty process
  • Reduced lead time for repairs and parts
Pump rebuilds can be performed by M.G. Newell in our Greensboro, Louisville or Nashville office.

In a rebuild, we pull the shafts, replace the bearings and all wear items. Depending on the amount of wear, we also replace the rotors. Our shop will perform an evaluation of the pump and provide you with an estimate to rebuild your pump. The cost of a rebuild is approximately 50% of the cost of a new pump. The only drawback to a pump rebuild is a slight loss in its original efficiency.

Our qualified technicians disassemble and evaluate pumps ranging in size from model 6 Universal to model 520 Universal.

Pump remanufacture is performed by SPX Flow at their factory. In this program, they only reuse four parts: the SS cover, body, gear case and gear cover. The remaining components are completely replaced with new, original equipment parts manufactured to factory specifications.
They bore the existing body and make new oversized rotors. This machining is the main difference between a rebuild and remanufacture. When complete, the pump is back to its original performance specifications and has a new 1-year warranty from SPX Flow.
Due to the new oversized body, standard rotors should not be used due to potential damage or failure of the pump. A pump can be remanufactured two times in its lifetime. The cost of a remanufactured pump is approximately 75% of the cost of a new pump.
