Some process chemicals are corrosive and would attack a metal pump. A polypropylene process pump is built from a plastic that resists them.
Because its wetted parts are made of polypropylene, the pump is not eaten away by the aggressive liquids it carries.
This guide explains what a polypropylene process pump does, where it fits, and how to keep it reliable.
What This Pump Does
The pump has its wetted parts made of polypropylene, a plastic that resists many corrosive chemicals.
So it moves aggressive liquids that would corrode a metal pump, without being attacked itself.
The pump handles these liquids at a steady flow while resisting the chemical it carries.
Where It Fits in the Plant
The plant and its distillery use corrosive process chemicals for treatment and cleaning, and these need a resistant pump.
A polypropylene pump moves these aggressive liquids where a metal pump would corrode quickly.
By resisting the chemical, it handles the corrosive duties reliably.
Signs the Pump Needs Attention
A polypropylene pump in trouble shows up in flow and the plastic.
- Flow falling as the pump wears
- Signs of the plastic being attacked or softened
- Cracking or damage to the plastic parts
- Leaks at the seal
- Vibration or noise while running
What Makes a Good Polypropylene Pump?
This pump is judged by chemical resistance and sound plastic parts.
Resistance to the Chemical
The polypropylene must resist the chemical the pump carries. Resistance is the whole reason for the plastic pump.
Sound Plastic Build
The plastic parts must be sound and free of cracks to hold the liquid. A sound build keeps the pump working without leaks.
Keeping the Pump Running
Routine attention keeps a polypropylene pump resisting the chemical.
- Match the pump to the chemical it carries
- Watch the plastic for attack or softening
- Check the plastic parts for cracks
- Keep the seal and drive maintained
Common Questions About Polypropylene Process Pumps
Polypropylene is a plastic that resists many corrosive chemicals, so the pump can carry aggressive liquids that would attack and corrode a metal pump.
On corrosive process chemicals used for treatment and cleaning in the plant and its distillery, where a metal pump would corrode quickly.
No. Polypropylene resists many chemicals but not all, so the pump must be matched to the liquid it will carry to be sure it resists it.
Matching the pump to the chemical, watching the plastic for attack, checking for cracks, and maintaining the seal keep it resisting the liquid.
Resist the Corrosive Liquid
A polypropylene process pump carries corrosive chemicals that would attack a metal pump, because its wetted parts resist them. Chemical resistance and a sound plastic build are what make it last.
