Pump Service & Maintenance

Pumps are increasingly becoming components of integrated systems in order to provide better control and efficiency of system processes, and conserve manpower. Goulds Pumps, for example, has developed “Pump Smart™” an integrated pump control system based on predetermined pump operating characteristics and VFD drives in lieu of control valves. As a result, and in an effort to help lead the way, we have also become systems and controls specialists.

Many of our sales and service personnel have been trained to specialize in this area to ensure that we properly serve our customers needs and to promote new and better ideas. Combining these skills with our traditional skills required to properly apply and keep pumps up and running has created a very unique industry where diversified experience counts. R.F. MacDonald Co. has that experience.
