Progressive cavity pumps are used in a wide variety of applications and industries. These pumps are designed for tough working conditions and to resist high temperatures.
Unfortunately, due to the constant strain these pumps tolerate and the overall wear they suffer, progressive cavity pumps require frequent maintenance, repair, and replacement parts. Lack of maintenance or misapplication can result in expensive repairs or replacement.
Running dry will quickly destroy expensive stators and rotors. The interference fit between the rotor and stator requires the fluid being pumped to lubricate the contacting surfaces. Running the pump dry is the most common cause of failure in cavity pumps.
Additional progressive cavity pump issues include:
ARO air operated diaphragm pumps can easily handle processes where fluids contain abrasives or could run dry.
Additionally, all ARO EXP Series pumps are Process Ready. As a standard feature, each EXP Series pump comes with connection points that provide a communication portal from your pump for process monitoring and control. Whether you have the need today or are planning to expand your capabilities in the future, ARO has the right solution to improve your connection to your process and maintenance system.
Maintenance for an ARO air operated diaphragm pump is simple, fast, and inexpensive when compared to progressive cavity pumps.
AODD pump advantages also include:
