Product Description
Pulsafeeder GreenLine (GLM) Diaphragm Metering Pump
For applications demanding reliability, chemical resistance, and low maintenance, the GreenLine (GLM) metering pump delivers. This mechanically actuated diaphragm pump is built for rugged industrial performance and offers compact efficiency across a broad range of flow rates and chemical types.
Ideal for chemical dosing and transfer, the GLM series is engineered to minimize cost of ownership while maximizing uptime and process integrity.
Key Operating Features
GreenLine pumps utilize a flat, multi-layer PTFE-faced diaphragm to provide long service life and exceptional chemical compatibility. The double-sided diaphragm is backed by a secure sealing system with multiple sealing beads, a secondary O-ring, and a retention plate to ensure leak-free operation and pressure containment.
The pump’s check valve assemblies incorporate auto-flushing, spherically contoured internals for uniform velocity and reduced turbulence—ideal for handling solids and slurries. Soft-seated O-ring valve designs improve priming, reduce noise, and enhance slurry handling (316L stainless configurations excluded).
Mechanical & Design Benefits
-
Rugged Diaphragm Construction: PTFE-faced, multi-layer diaphragm offers reliable performance and high chemical resistance.
-
Sealed Diaphragm Assembly: Dual sealing design with O-ring and retention plate eliminates leaks and pressure creep.
-
Advanced Check Valve Design: Auto-flushing, turbulence-minimizing check valves reduce cavitation and improve solids handling.
-
Compact Gearbox: Lightweight, sealed gearbox with oversized shielded bearings extends life, minimizes maintenance, and operates quietly.
-
Auto-Locking Stroke Adjustment: Set it and forget it—adjust stroke once and rely on built-in locking to maintain accuracy.
-
Motor Protection: Flange design redirects fluid away from shaft seals and prevents fluid pooling.
-
Non-Metallic Motor Coupling: Prevents shaft galling or seizing, making motor installation and removal hassle-free.
-
Stable Mounting: Flat, solid mounting feet ensure secure, tip-resistant placement before and after installation.
Optional Upgrades
-
Leak Detection System: Available with double diaphragm, pressure gauge, and alarm switch for real-time diaphragm monitoring.
-
Variable Frequency Drive (VFD): Enables remote speed and flow control with greater flexibility and efficiency.
