OSD-810A 20:1 High-Pressure Piston Pump Hot Melt Glue Machine

1. Product Overview

The OSD-810A is a high-pressure piston pump hot melt glue machine featuring a 20:1 compression ratio, designed for applications that require higher adhesive output pressure, high-viscosity hot melt adhesives, or long-distance glue delivery. It features a 10L melting tank, 3,500W heating power, a melting capacity of 10kg/h, and supports 1–4 hot melt hoses.

The key difference between the OSD-810A and other piston pump models is its 20:1 pneumatic-to-hydraulic pressure amplification ratio. With a compressed air supply of 0.5–0.8MPa, the piston pump can theoretically generate a hydraulic output pressure of approximately 10–16MPa under ideal conditions. Actual working pressure depends on operating conditions and system losses.

This high-pressure capability makes the OSD-810A suitable for demanding applications where standard piston pumps may struggle to deliver adhesive consistently, including thick-layer coating, high-viscosity adhesive dispensing, and long-distance adhesive supply.

2. Why Choose the OSD-810A 20:1 Piston Pump?

The OSD-810A is designed for production lines that need higher adhesive delivery pressure rather than simply a larger melting tank or higher heating power.

When working with adhesives approaching 15,000–20,000 CPS, resistance to flow increases. Long hot melt hoses, small dispensing openings, and coating heads with narrow gaps can further increase pressure requirements. Under these conditions, a standard 10:1 piston pump may experience reduced output, unstable adhesive flow, or intermittent glue delivery if the available pressure is insufficient.

The OSD-810A’s 20:1 compression ratio provides greater pressure amplification to help overcome these challenges. It is particularly suitable for applications involving high-viscosity adhesive coating, long-distance centralized glue supply, and thick adhesive layers.

4. Applications of the OSD-810A

The OSD-810A high-pressure piston pump hot melt glue machine is suitable for industrial applications requiring reliable adhesive delivery under demanding operating conditions.

Typical applications include:

• High-Viscosity Adhesive Coating: Applying high-viscosity hot melt adhesives in industrial manufacturing processes.
• Long-Distance Centralized Glue Supply: Delivering molten adhesive through extended hoses to remote production stations.
• Thick-Layer Scraping and Coating: Supplying adhesive to coating heads that require higher pressure to maintain consistent material flow.
• Woodworking and Furniture Manufacturing: Supporting adhesive application for furniture wrapping, panel lamination, and surface bonding.
• Automated Production Lines: Supplying hot melt adhesive to 1–4 workstations, depending on production requirements.

The OSD-810A is particularly suitable for production lines requiring approximately 10kg/h of melting capacity, higher adhesive delivery pressure, and stable feeding of high-viscosity materials.

5. How to Choose the Right Piston Pump Hot Melt Glue Machine

Selecting the correct pump depends on adhesive viscosity, required output pressure, hose length, coating method, and the number of production stations.

• Choose the OSD-810A if your adhesive viscosity approaches 20,000 CPS, your hot melt hoses are longer than approximately 8 meters, or your application requires high-pressure thick-layer coating.
• Consider the OSD-806A if your adhesive has a moderate viscosity and your process does not require the higher pressure amplification of a 20:1 pump.
• Consider the OSD-108A gear pump hot melt glue machine if your process is better suited to a gear pump configuration and does not require the OSD-810A’s specific high-pressure piston pump design.
• Consider the OSD-815A if your production line requires up to six hot melt hose connections or a dual-piston configuration.

Before selecting a machine, confirm the adhesive’s operating viscosity, required application temperature, hose dimensions, dispensing head specifications, and actual pressure requirements with our technical team.
