In industries like printing, packaging, and self-adhesive label production, precision and consistency are critical to both product quality and operational efficiency. Applications such as photopolymer coating demand exact fluid control, minimal material waste, and the capacity to support high-volume, continuous processes without interruption.

‍

This is where the Ovell diaphragm pump provides a valuable solution.

Used across various sectors, this type of air operated diaphragm pump has proven especially effective in the printing industry and packaging industry, offering a safe, efficient, and highly adaptable pumping system. Key advantages include:

• Precise fluid feed control to prevent over- or under-coating

• Material recovery and waste reduction

• Low maintenance and flexible installation

‍

A standout example of this technology in action is its adoption by Avery Dennison — a Fortune 500 enterprise and one of the global leaders in printing and adhesive materials. Their use of the Ovell diaphragm pump underscores its reliability in fast-paced, high-demand manufacturing environments.

Why Pneumatic Diaphragm Pumps Are Ideal for the Printing Industry

In any coating or printing process, consistent material flow is key to product quality. Pneumatic diaphragm pumps offer several features that make them a top choice for these applications:

• Self-priming capability: Enables quick start-up without complex priming steps.

• Dry-run tolerance: Can operate safely even if fluid supply is temporarily interrupted.

• Non-electric operation: Reduces risk in flammable or moisture-rich environments.

• Gentle, pulse-free flow: Protects delicate coating materials like photopolymer solutions.

‍

Thanks to these features, diaphragm pumps have become a preferred choice for coating lines, glue systems, ink transfer, and chemical supply in printing and label production facilities.

Their flexible design makes them suitable for materials ranging from low-viscosity liquids to thicker resins and adhesives, making them a go-to pump type for demanding manufacturing settings.

Application Example: Used at Avery Dennison’s Facility

Avery Dennison, a Fortune 500 company and global leader in labelling, adhesives, and digital identification technologies, operates advanced manufacturing facilities worldwide. At its facility in China, the company employs the 1-inch aluminium alloy diaphragm pump to optimise its photopolymer coating process on printing machines.

This pump plays a key role in ensuring coating consistency and material efficiency, which are vital in high-volume industrial printing. Here’s how it contributes to the operation:

‍

1. Precise Photopolymer Coating Transfer

The pump delivers a steady, controlled flow of photopolymer coating fluid onto the printing line. In a process where coating thickness and uniformity are essential, maintaining a stable feed prevents defects and ensures product consistency.

‍

2. Dual Inlet/Outlet Efficiency

One inlet is equipped with a control valve to accurately manage flow rate, helping to prevent issues like overcoating or under-application.

The second inlet functions as an overflow return system — transferring excess material from the overflow trough back to the storage tank. This not only prevents fluid waste and contamination but also supports immediate material reuse, reducing cost and supporting sustainable production.

‍

3. Seamless Integration into High-Speed Production

In Avery Dennison’s fast-paced production line, equipment reliability is critical. The pump’s consistent performance and low-maintenance design help minimise downtime, making it a dependable part of their automated coating system.

This same diaphragm pump model is also widely applied across the printing industry and packaging industry, thanks to its ability to handle coatings, adhesives, and other complex fluids with minimal waste and high efficiency.

Key Features That Make This Pump Industry-Ready

1. Dual Inlet and Outlet Design

What it is: A configuration with two inlets and two outlets.

Why it matters: Allows for simultaneous material control and return, or multi-directional fluid distribution.

Benefit: Reduces system complexity and cost by eliminating the need for additional pumps in multi-step or dual-line processes.

‍

2. Aluminium Alloy Construction

What it is: A lightweight yet durable pump body material.

Why it matters: Aluminium resists corrosion and wear in most industrial environments while reducing the weight burden on mounting systems.

Benefit: Extended service life with fewer replacement cycles, ideal for non-stop operations.

‍

3. Pneumatic (Air-Operated) Drive

What it is: A system powered entirely by compressed air.

Why it matters: No risk of electrical sparks or failures in fluid transfer zones.

Benefit: Safe, energy-efficient operation even in humid or chemically active areas.

‍

4. Self-Priming and Dry-Run Capability

What it is: The ability to draw fluid without manual priming and tolerate dry operation.

Why it matters: Avoids delays during start-up and reduces risk of pump damage when fluid flow is inconsistent.

Benefit: Reliable performance under variable load and supply conditions.

‍

Benefits in the Printing and Label Industry

Here are the key benefits realised by industrial users, including printing and adhesive product manufacturers:

‍

1. Consistent Coating Quality

Precise feed control ensures stable application of photopolymer coatings, adhesives, and glues.

Result: Improved product finish and reduced rework.

‍

2. Reduced Waste

Overflow recovery enables the reuse of excess material, avoiding contamination.

Result: Lower material costs and greener operations.

‍

3. Lower Equipment Investment

Dual-function design eliminates the need for multiple pumps in split-line or dual-feed systems.

Result: Reduced fixed asset spending.

‍

4. Safe for Sensitive Materials

Gentle pumping action and air operation mean no risk of damaging delicate fluids or additives.

Result: Protected fluid integrity and longer equipment life.

‍

5. Adaptability Across Applications

From chemical dosing to adhesive transfer, this pump suits many fluid types and industries.

Result: One solution for multiple needs.
