COMPANY OVERVIEW

WearCheck

THEN…

Our story began about 40 years ago, when founding directors Lesley and Wally Crawford, and Gary Brown set up oil analysis operations in 1976 in a home laboratory. Their initial test portfolio comprised six elements - viscosity, water, fuel, sludge and debris analysis, with no automation. The company employed 10 people and processed less than 500 samples per month.

…AND NOW

From those humble beginnings, the company has flourished and grown, and today WearCheck is one of the leading condition monitoring specialists on the African continent, processing in excess of 600 000 samples per annum. We have evolved into a one-stop-shop for a vast range of reliability solutions services across many industries, and we are proud to be a member of the prestigious International WearCheck Group (IWG).

The IWG is an association of independent laboratories around the globe, dedicated to oil and wear particle analysis. WearCheck’s relationship with the IWG allows for the ongoing exchange of advanced technical information, and the ability to offer a worldwide service.

 

WHY USE WEARCHECK?

One of WearCheck’s fundamental goals is to save money and time for customers by improving the availability, reliability and efficiency of their machinery through regular maintenance and tailored condition monitoring programmes. 

The development of WearCheck’s reliability solutions division embraces the latest approach to proactive maintenance - the search for ways to extend the life of components to prevent premature failure, thereby boosting general plant health.  The underlying philosophy is that any good proactive maintenance programme boosts both plant availability as well as plant reliability.

WHO USES CONDITION MONITORING?

Using results from the scientific analysis of used oil, fuels, coolants and greases from components for plant maintenance decisions, many industries benefit from WearCheck’s services, among them mining, earthmoving, industrial, transport, shipping, aviation and electrical operations.

WHERE CAN I FIND WEARCHECK?

WearCheck’s expansive network of 13 laboratories spans the African continent and beyond, including Isando in Gauteng, Pinetown in KwaZulu-Natal, Middelburg, Lumwana mine and Kitwe in Zambia, as well as Ghana, Mozambique, DRC, Zimbabwe, Namibia, India and Dubai (in partnership with Precision Machinery), with additional offices in Cape Town, Rustenburg, Steelpoort and Port Elizabeth

WearCheck has a unique achievement – we are the only oil analysis company in Africa with ISO 9001 quality certification and ISO 14001 certification for our environmental management programme, as well as being accredited with the ISO 17025 laboratory centric quality management programme.

 

OIL ANALYSIS SERVICES

Oil analysis is as important for maintenance engineering as blood testing is for medicine. It is the scientific analysis of all types of lubricants and transformer oils, coolants, greases and filters and is an established method for predictive and preventive maintenance. Preventive maintenance programmes are essential for optimising operational efficiency, reliability and performance of mechanical and electrical systems. WearCheck offers many services for predictive and preventive maintenance, including competitive pricing and short turnaround time. Analyses are carried out at state-of-the-art, custom built, automated laboratories with interpretation and reports being completed by our highly-qualified diagnosticians.

The company's services include:

  • Viscosity
  • Density
  • Distillation
  • Flashpoint
  • Water (by Karl Fischer) 
  • Appearance / colour
