Pulsafeeder GreenLine: The Industrial Standard for Precision Chemical Metering

Engineered for Resilience. Defined by Precision.

In demanding industrial environments, a pump is more than just hardware—it is the heartbeat of your chemical processing or water treatment system. The Pulsafeeder GreenLine (GLM) Series is a mechanically actuated diaphragm pump engineered for those who cannot afford downtime. By combining a robust industrial gearbox with a high-performance, leak-free wet end, the GreenLine delivers precise dosing and unmatched longevity in the toughest conditions.

The most common failure in chemical metering is "flow drift" caused by operational vibrations. The GreenLine eliminates this through its Auto-Locking Stroke Adjustment mechanism.

• 1% Resolution: Dial in your exact flow rate with an intuitive, high-resolution adjustment knob.

• Zero Drift: Once set, the self-locking design ensures your chemical dosing remains consistent without the need for secondary locking tools or frequent manual readjustment.

Five-Layer Diaphragm Technology: Built for Millions of Cycles

At the core of the GreenLine’s reliability is the advanced Multi-Layer Composite Diaphragm.

• Double-Sided PTFE Coating: Provides maximum chemical resistance and internal lubrication.

• High-Strength Nylon Fiber: Adds structural integrity for a service life exceeding millions of cycles.

• Natural Rubber Core: Enhances shock absorption and vibration resistance.

Total Containment: A Leak-Free Guarantee

Safety and compliance are non-negotiable when handling acids, caustics, and polymers. The GreenLine series utilizes a Secure Diaphragm Sealing design and a Double-Barrier Check Valve assembly.

• Secondary O-Ring Seals: Provide a fail-safe against chemical spray and leaks.

• Retention Plate: Eliminates "creep" and distortion at high pressures, ensuring the head bolts maintain constant torque.

• Optional Leak Detection: For critical applications, available double-diaphragm systems with integrated pressure gauges alert operators before a failure becomes an environmental hazard.

Optimized for the Modern Plant

Whether you are upgrading a facility or designing a new process, the GreenLine is built for seamless integration:

• VFD Compatibility: Maximize your operating range and enable remote control with optional Variable Frequency Drive motor configurations.

• Contamination-Proof Gearbox: A fully sealed, non-vented design protects internal oversized bearings from dust, moisture, and corrosive fumes.

• Toolless Maintenance: Spherically uniform velocity check valves and "never-seize" motor couplings allow for rapid servicing without specialized tools.
