A Beginner’s Guide to Progressive Cavity Pumps
Progressive cavity pumps (PC) are a type of positive displacement pump designed for handling high-viscous fluids and tough pumping applications. They consist of a helical rotor and a twin helix stator, creating small cavities for fluid transfer. PC pumps are versatile and widely used in various industries due to their ability to handle abrasive fluids effectively. Considerations for selection include fluid viscosity, temperature, and abrasiveness.
How Progressive Cavity Pumps Work
Progressive cavity pumps, also known as screw pumps, operate by moving fluid through a series of small cavities formed by a rotating helical rotor inside a stator. These pumps are ideal for high-viscosity fluids and applications with solids. The rotor and stator assembly is the core of the pump, providing steady fluid transfer from intake to discharge. Proper maintenance and selection based on fluid properties are crucial for efficient operation.
Tips for Reliable Operation & Reduced Maintenance
- Stators typically wear out first, replace rotor for every two stators
- Check rotor wear at proper intervals to save on replacement costs
- Use non-petroleum based lubricant when installing rotors into stators
- Protect stators from heat, humidity, UV light, and ozone for storage
- Purchase spare and replacement parts from the same manufacturer for compatibility
