The following sections will help you understand how our pumps can meet the demands of inkjet printing systems, ensuring stable ink circulation, precise pressure control, and long-term reliability
BODENFLO’s diaphragm liquid pumps and diaphragm air pumps are specifically designed to meet the demands of inkjet printing systems, ensuring precise ink circulation, stable pressure control, and long-lasting performance. Our pumps are engineered for industrial, commercial, and specialty printing applications, offering unparalleled reliability and efficiency.
Understanding the technical specifications is crucial for selecting the right diaphragm ink pump for your inkjet printing system. Below are the key technical aspects of BODENFLO’s diaphragm liquid pumps and diaphragm air pumps, designed to ensure precise ink circulation and pressure control.
Inkjet printing systems, including coding and marking printers, rely on precise ink flow management to maintain consistent print quality, prevent nozzle clogging, and ensure efficient ink utilization. Two critical types of pumps support these functions:
These pumps are essential in Continuous Inkjet (CIJ), Drop-on-Demand (DOD), UV-curable inkjet printing, and industrial coding and marking systems, providing stable ink movement and precise pressure regulation for high-speed, industrial, and commercial printing applications.
Ink circulation pumps, also known as diaphragm liquid pumps, ensure a continuous and stable flow of ink throughout the printing system. They prevent ink sedimentation, viscosity changes, and air bubble formation, which could otherwise impact print quality.
Key Benefits of Ink Circulation Pumps:
✅ Maintains a controlled and consistent ink flow, ensuring smooth operation.
✅ Low pulsation output, reducing pressure fluctuations for precise ink delivery.
✅ Chemical-resistant materials for compatibility with water-based, solvent-based, and UV inks.
✅ Maintenance-free design, eliminating the risk of oil contamination.
Recommended Applications:
To maintain a stable and controlled ink supply, inkjet printing systems require precise pressure management. Pressure regulation pumps play a crucial role in preventing ink overflow, ensuring proper ink droplet formation, and maintaining supply consistency.
Key Benefits of Ink Circulation Pumps:
✅ Regulates ink system pressure, preventing supply fluctuations and ensuring consistent output.
✅ Prevents ink foaming and air bubble formation, improving printhead performance.
✅ Compatible with high-viscosity and UV-curable inks, making them ideal for industrial applications.
✅ Compact, low-noise design, suitable for high-speed printing environments.
Recommended Applications:
Inkjet printing systems demand precision, reliability, and consistency in ink supply to maintain high-quality print output and reduce downtime. However, common challenges such as ink sedimentation, air bubbles, pressure fluctuations, and ink leakage can affect performance.
BODENFLO’s diaphragm liquid pumps and pressure control pumps are designed to solve these problems, ensuring stable ink circulation, precise pressure regulation, and extended pump lifespan. Below, we explore the common ink supply issues and how our pumps overcome them, with key technical specifications to ensure the best performance.

At BODENFLO, we prioritize the quality and longevity of our diaphragm ink pumps, ensuring they meet the rigorous demands of industrial inkjet printing. From high-speed production lines to UV and solvent-based printing, our pumps are designed to provide stable ink circulation, precise pressure control, and extended operational life.
The materials used in our pumps play a crucial role in their durability. We incorporate PTFE, FKM, FFKM, and EPDM diaphragms, all of which offer high resistance to aggressive ink formulations. The PP and PPS pump bodies ensure structural integrity and chemical compatibility, preventing corrosion and degradation over time. Combined with brushless and brush DC motors, our pumps maintain low noise, low heat generation, and high efficiency, making them ideal for continuous operation.
Inkjet printing systems require consistent ink flow and precise pressure regulation to ensure uniform print quality and prevent disruptions. BODENFLO’s diaphragm ink pumps are designed with low-pulsation technology, minimizing flow fluctuations that could affect ink droplet formation. The combination of high-torque diaphragm mechanisms and advanced motor control allows for smooth, uninterrupted ink circulation, even in high-speed and high-viscosity printing environments.

We simulate real-world industrial conditions, including high-speed ink circulation, temperature fluctuations, and pressure variations, to guarantee consistent performance in demanding printing environments. Our pumps are CE and ROHS certified, meeting international quality and safety standards.
Designed for 24/7 continuous operation, our pumps eliminate frequent maintenance concerns with an oil-free, self-priming, and low-pulsation design. With a lifespan of up to 8000 hours, they provide a cost-effective, long-term solution for industrial ink supply. Their compact and lightweight structure ensures easy integration into both small and large-scale printing systems.
Selecting the right ink pump for your printing system is essential to ensure consistent ink flow, optimal pressure control, and long-term reliability. The right choice depends on factors such as ink type, printing speed, pressure requirements, and system integration.
Determine the viscosity, chemical composition (solvent-based, UV-curable, water-based), and particle size of the ink. Pumps must be compatible with these properties to avoid degradation or clogging.
Calculate the required flow rate (e.g., liters per hour) and pressure to ensure consistent ink delivery. High-speed printing may demand pumps with precise flow control.
Select pump materials (e.g., stainless steel, PTFE, ceramics) that resist corrosion, abrasion, or chemical reactions with the ink to ensure longevity.
Opt for pumps with precise metering capabilities (e.g., gear pumps, diaphragm pumps) for applications requiring exact ink volumes, such as digital or gravure printing.
Choose designs that allow quick disassembly, cleaning, and replacement of parts to minimize downtime during ink changes or maintenance.
Evaluate pump types: Gear pumps: Ideal for high-viscosity inks. Peristaltic pumps: Suitable for shear-sensitive inks. Diaphragm pumps: Good for abrasive inks. Centrifugal pumps: Best for low-viscosity, high-flow needs.
Prioritize energy-efficient motors and quiet operation, especially for large-scale or indoor printing environments.
Ensure compatibility with your printer’s control systems (e.g., PLCs, IoT-enabled devices) for seamless automation and monitoring.
