Ink Pump & Filter Selection for Industrial Printers | Grisprint

Select the right ink pump and filter for Ricoh MH5420 (10–12 mPa·s) and Epson I3200 (3–4 mPa·s). Match components to viscosity and ink type. Compatible 5μm, 10μm, 15μm filters in stock. Global shippin

Selecting compatible ink pumps and filters based on printhead specifications ensures stable operation and protects critical components. Matching system design to ink viscosity and printhead requirements is essential for reliable performance in industrial inkjet applications.

This guide references official specifications from Ricoh MH5420/MH5440 and Epson I3200 series print heads to support informed component selection.

1. Printhead Specifications: Viscosity & Ink Compatibility

The ink delivery system must align with the printhead’s defined viscosity range and chemical compatibility. Below are verified parameters from manufacturer datasheets.

Note: Operating outside the specified viscosity range may affect droplet formation, jetting stability, and printhead longevity. Always confirm compatibility with your ink supplier.

2. Filter Selection by Ink Type and Viscosity

Filtration prevents particulate contamination that can lead to nozzle blockages. While exact micron ratings are not specified in the datasheets, industry best practices recommend pore size based on ink type and viscosity.

Use chemically resistant materials to avoid filter degradation and downstream contamination.

3. Common System Configurations

Based on standard integration practices and printhead specifications, the following combinations are widely adopted in industrial printing systems.

These setups support stable ink circulation and are compatible with common diaphragm pump systems.

4. Maintenance Considerations

Neither Ricoh nor Epson specifies pump or filter replacement intervals in their public datasheets. However, consistent maintenance supports long-term printhead health.

Recommended practices:

Filter: Perform visual inspection weekly; replace when pressure drop is observed or after extended use.

Pump: Monitor flow consistency and check for air ingress or seal wear.

For optimal results, follow your equipment integrator’s maintenance guidelines.
