Fortis MC Plungers

Fortis MC Ceramic and Metal-Coated Plungers

Triangle Pump Components, Inc. (TPCI) offers a variety of reciprocating pump plungers for a wide range of applications. Both the Fortis MC ceramic and metal-coated plungers have specific properties that lend themselves to different situations. It is therefore essential that the right plunger material is selected to ensure that pumps operate safely and efficiently in a given environment. Next, we will describe each plungers’ benefits and look at the situations in which each is most suitable.

Our Fortis MC Ceramic Plunger

These ceramic plungers inherit the hard and wearable nature of their ceramic parent material, making them more durable than metal coated plungers when used in ideal conditions. The relatively low density of this material also makes it lighter and easier to manage, repair, and maintain than metal-coated plungers.

Fortis MC ceramic plungers also tend to be more efficient due to their seemingly self-lubricating nature. Ceramics have a lower coefficient of friction than metal, resulting in less sliding resistance of the plunger and reduced wear during prolonged operation.

Our Fortis MC Metal-Coated Plunger

In terms of mechanical properties, the Fortis MC metal coated plungers possess higher strengths than ceramic plungers, allowing them to resist significant amounts of thermal shock, abrasion, vibration, and impact forces. Common alloys used in the construction of metal-coated plungers include Colmonoy, Tungsten Carbide, and Wallex. TPCI can custom manufacture plungers from other metal alloys for unique applications upon customer request.
