Advanced Performance with Pulsafeeder Green Line Metering Pumps
Pulsafeeder Green Line mechanically actuated diaphragm metering pumps deliver accurate and consistent chemical dosing for industrial water treatment systems. Designed for demanding environments, these pumps combine durability, leak protection, and smooth flow control for reliable operation.
In addition, the multi-layer PTFE-faced diaphragm resists aggressive chemicals and extends service life. Multiple sealing beads help reduce leak risk. The advanced double-seal diaphragm system with a secondary O-ring and retention plate improves hydrostatic protection and prevents chemical spray. As a result, operators gain safer and more secure performance.
Moreover, the double-barrier check valve assembly enhances leak resistance, while spherically balanced check valves reduce turbulence and improve solids handling. The soft-seated O-ring valve design also improves priming and lowers operating noise.
The compact, fully sealed gearbox protects internal components from contamination and reduces maintenance. Oversized shielded bearings increase durability and extend motor and gear life. The auto-locking stroke adjustment keeps settings firmly in place during operation.
Additional features such as the motor flange drain path and non-metallic motor coupling simplify maintenance and protect key components. Stable mounting feet ensure secure installation.
Optional upgrades include a leak detection system for diaphragm monitoring and a VFD-compatible motor for expanded control flexibility.
Because of their rugged construction and steady output, Pulsafeeder Green Line metering pumps perform reliably in cooling towers, boiler systems, chemical injection skids, and industrial process dosing applications. Available from Water Treatment Supply, they provide dependable chemical feed control for demanding environments.
