Advantages of Choosing a Polypropylene Pump

Posted: 4/15/2015


Polypropylene, or PP, is a thermoplastic polymer that pump manufacturers use on a variety of products. The polymer is known for its unique combination of lightweight construction, high strength against deformation and high chemical resistance. The material is also a cost-friendly alternative to metallic elements. If you are in the market for a new magnetic drive pump, here are the main reasons why you should consider installing polypropylene-made mag drive pumps.

Polypropylene was first created by chemists J. Paul Hogan and Robert L. Banks at Phillips Petroleum in 1951. Commercial production of the material began in 1957, and has been used in the fabric, injection molding, chemical processing, food, pharmaceutical, petrochemical and oil industries.

Pump manufacturers have adopted polypropylene into their product line because of its unique characteristics:

• Excellent resistance to stress and high resistant to cracking
• High operational temperatures with a melting point of 160°C
• Excellent strength-to-weight ratio
• Highly resistant to most alkalis and acid, organic solvents, degreasing agents and electrolytic attack

There are several additional advantages to using polypropylene pumps. Pumps built with polypropylene are corrosion resistant, and can withstand many acids, solvents and alkalis. The heavy duty construction and molding prevents leakage and extends the life of the pump. Most importantly, PP pumps are easy to produce and assemble upon construction, and lowers overall costs.

March pumps made with polypropylene include:

BC-3CP-MD Magnetic Drive Pump

This American made centrifugal pump is ideal for chemical recirculation and chemical transfer. The BC-3CP-MD has pumped Acetic Acid, Citric Acid, Ethylene Glycol, Formaldehyde, Hydrochloric Acid (Muriatic), Nitric Acid, Phosphoric Acid, Potassium Chloride, Potassium Hydroxide, Sodium Hydroxide (Caustic Soda), Sodium Chloride, Sulfuric Acid, Fresh Water, Salt Water, DI Water, and many more chemicals.

BC-2CP-MD Magnetic Drive Pump

This magnetic drive pump is built with a polypropylene impeller and front and rear housing. Applications include ice makers, laboratory and medical equipment, vapor degreasers, and marine air conditioning systems. This pump is also able to handle the chemicals above that the BC-3CP-MD withstands.

BC-4C-MD-AM Magnetic Drive Pump

This pump also contains a polypropylene impeller and housing. It is capable of handling mild to highly corrosive chemicals and solvents. It is ideal for use in chemical recirculation and transfer applications.


Polypropylene is highly adaptable and economical option for magnetic drive pumps. The polymer stands up to aggressive chemicals, requires low maintenance and is less expensive to produce. Consider a polypropylene pump for your next centrifugal pump. For more information, contact us today.
