 Kynar Made March Pump

If you are looking for a competitive price option for your next mag drive pump for a highly corrosive chemical, a pump built with Kynar, or polyvinylidene fluoride (PVDF), is your answer. 

Kynar, the trademark name for PVDF, is a thermoplastic fluoropolymer that is used in applications that require the highest level of strength and resistance to chemicals, solvents, acids and heat. Commonly used in the chemical industries, it is known for its low weight, high flexibility and high corrosion resistance.

First developed in France in 1960 by Arkema, it was used initially for chemical handling applications. It has since been used in several industries, from biotechnology and electronics to food production.

Kynar pumps offer a higher corrosion resistance and permeation resistance then metallic pumps, and can complete the everyday tasks needed in your facility. As you explore your options, there are several factors to consider when choosing the pump that fulfills your needs.

Pumps can be made wholly from plastic or lined with plastic. There are advantages and disadvantages to each type of pump. Pumps made entirely from Kynar PVDF have one main difference: they are less expensive.

Plastic lined pumps are coated with costly EFTE or PFA plastics, which can increase your expenses. Plastic lined pumps are heavier to move, which also increases freight costs. Plastic lined pumps are known for their chemical handling ability, but their level of design is not necessary for every pumping application.

A March Kynar plastic pump can be a less expensive, more suitable option for certain applications under 200GPM. Plastic lined pumps with ETFE are superior to Kynar pumps in their ability to handle a variety of chemicals, but most chemical applications do not require a superior level of resistance and consequently the higher price. Kynar pumps can do the job needed.

March Kynar pumps have a max internal pressure that can range from 60PSI to 75PSI. These pumps can tolerate a max temperature (with water) of 200F. While some chemicals may be compatible with Polypropylene and Ryton at room temperature, in many cases Kynar is better at higher temperatures. PVDF pumps are chemically resistant to chemicals including, but not limited to, Sodium Hypochlorite, Chrome Alum, Chlorine, Dichloroethylene, Ethylene Dichloride, Hydrofluoric Acid, Kerosene and Phosphorus Trichloride.
