An ink pen pump, commonly known as an ink converter, is a device used in fountain pens that allows them to be filled with ink directly from a bottle, rather than relying solely on disposable ink cartridges. It essentially gives a cartridge-only fountain pen the functionality of a piston-filler pen.
Understanding the Ink Converter
The term "ink pen pump" often refers to a specific type of mechanism within the fountain pen. As stated in the reference: "Internation standard size ink converter is also known as an ink pump." This highlights that the two terms are often used interchangeably, particularly for the standard size converters designed to fit many fountain pens.
How Does an Ink Pen Pump Work?
The primary mechanism of an ink pump or converter is typically a piston system. According to the provided reference: "This is a piston converter/pump, which means you twist the grip to move the piston up and down the pump cylinder which draws the ink from the ink bottle through the fountain pen nib into it."
Here's a breakdown of the process:
- Connecting: The converter (ink pump) is inserted into the section of the fountain pen, replacing an ink cartridge.
- Submerging: The nib and part of the pen's section are submerged into an ink bottle.
- Twisting Action: You twist a knob or the end of the converter. This rotation causes a piston inside the converter's cylinder to move.
- Creating Suction: As the piston moves upwards within the cylinder, it creates a vacuum.
- Drawing Ink: The pressure difference (higher atmospheric pressure on the ink in the bottle vs. lower pressure inside the converter) forces ink up through the pen's feed and nib and into the converter's reservoir.
- Filling: The twisting continues until the converter is filled with ink.
This mechanism allows users to access the vast array of bottled fountain pen inks available, offering more color choices and often a more economical and environmentally friendly option compared to disposable cartridges.
Key Features of an Ink Pen Pump (Converter)
- Reusable: Designed to be filled repeatedly from an ink bottle.
- Piston Mechanism: Uses a twisting action to operate a piston for drawing ink.
- Compatibility: Available in various sizes (e.g., international standard) to fit different pen models.
- Alternative to Cartridges: Provides the flexibility to use bottled inks.
Using an ink pump is a fundamental aspect of enjoying the wider world of fountain pen inks, transforming a simple cartridge pen into a versatile tool for writing and creative expression.
