Over the past 2 decades, the main technological advances in the engineering of Warman pumps have been primarily in the areas of wear resistance, serviceability, and the development of more durable pumps. According to the company, a pump’s efficiency and hydraulics don’t count much if the pump cannot pump or if there isn’t water coming out at the other end of the pipe. Nonetheless, by ensuring that a pump has the highest wear resistance and is easy to maintain and service, optimum uptime and efficiency are easily ensured.

Easy To Service Designs

To ensure that the pumps are easier to maintain and service, external oil plugs as well as inspection chambers have been incorporated in the design of Warman pumps to eliminate the need to open and dismantle them during servicing. Additionally, it is now much simpler to adjust the impeller. Generally, when the impeller wears out, the pump’s performance drops significantly. By adjusting the impeller, however, full performance is regained and the pump operates at its best efficiency.

More Robust and Tough Pumps

Dewatering pumps, especially those used in mines need to be tough and robust to withstand the challenging environment. Over the past few years, the increasingly demanding site conditions and business climate characterized by dwindling resources have necessitated even more durable and reliable engineering technologies. More durable pumps can operate at their optimum levels over a longer duration of time, which in turn lower energy consumption.

High performing materials

Another significant advancement in the engineering of Warman pumps over the past 2 decades involves the integration of high performing materials. For instance, instead of using packing materials which was the original sealing method of choice, today’s pump packing come in a wide range of choices , customized nearly for every application. There has also been a shift from conventional physical properties to more modern viscoelastic properties in the design of rubber formulations. Additionally, there are better ways of understanding wear mechanisms in every component of the pumps. This has resulted into the development of new compound formulations for every form of wear mechanism and possibility of using “dual” compounds in design of the modern Warman pumps.

Conclusion

The changes in the engineering and design of Warman pumps in the past 2 decades have majorly been a result of technological developments than the use of new raw materials. For instance, hard iron and stainless steel which are widely used in the pump manufacture industry are still used in these pumps. Going forward, improvements in these pumps will still probably result from good hydraulic designs and smart technologies that boost the pumps’ wear resistance, performance, and efficiency.
