GreenLine Chemical Transfer Pumps
Best for: Demanding industrial environments requiring reliable diaphragm metering pumps with continuous-duty operation
An industrial-grade chemical transfer pump engineered for precision, longevity, hands-off operation
Pulsafeeder’s GreenLine, an integral part of our extensive positive displacement pump and diaphragm pump families, is a mechanically actuated diaphragm pump specifically engineered for water treatment plants, chemical processing facilities, mining operations, and manufacturing environments where reliability is non-negotiable.
GreenLine chemical transfer pumps deliver three critical advantages that heavy industry demands:
- Operational simplicity and control precision
- Proven industrial durability and extended service life
- Leak-resistant safety and compliance
With auto-locking stroke adjustment that eliminates flow drift, contamination-proof gearbox design that withstands harsh conditions, and multi-million cycle diaphragm technology that extends service life, GreenLine chemical transfer pumps deliver consistent chemical dosing performance with minimal maintenance intervention.
When pump downtime isn’t an option, choose the transfer pump for chemicals designed for worry-free industrial reliability.
Auto-locking precision eliminates flow drift and constant readjustment
The GreenLine diaphragm metering pump’s auto-locking stroke adjustment mechanism maintains precise flow settings without secondary locking mechanisms or gradual drift from vibration and operational stresses. Set your exact flow rate once using the 1% resolution adjustment knob, and the self-locking design ensures consistent chemical dosing without periodic readjustment—eliminating a common maintenance task with standard adjustment mechanisms.
Contamination-proof gearbox withstands the harshest industrial environments
The GreenLine chemical transfer pump’s fully sealed, non-vented gearbox design prevents dust, moisture, chemicals, and other contaminants from degrading internal components. Oversized shielded bearings and oil bath lubrication ensure long service life even in demanding conditions, delivering reliable operation regardless of environmental conditions—from dusty mining operations to humid chemical processing plants.
Service-friendly design minimizes maintenance time and complexity
Never-seize motor coupling prevents sticking, toolless valve removal enables quick service, and accessible oil fill locations simplify routine maintenance. The spherically uniform velocity check valves limit turbulence, decrease noise, and provide superior solids handling with auto-flushing ability. The non-metallic motor coupling allows easy motor installation without specialized tools.
Multi-million cycle PTFE diaphragm pump technology for extended service life
GreenLine’s double-sided PTFE faced, multi-layer composite diaphragm is engineered for over one million cycles of reliable operation. Multiple sealing beads prevent leakage under demanding conditions, while the PTFE coating provides superior chemical resistance and lubrication that extends diaphragm life and reduces total cost of ownership.
Multiple containment barriers ensure safe chemical handling
The GreenLine diaphragm metering pump’s leak-resistant design incorporates secondary O-ring seals, self-contained double barrier check valve assembly, and secure diaphragm sealing technology. These multiple protection layers prevent chemical exposure even if primary seals fail, protecting personnel and the environment while helping facilities meet safety standards.
Versatile suction lift pump attributes offer precise turndown control
Configure your GreenLine chemical transfer pump as a variable frequency drive pump to maximize operating range and enable remote control capabilities. VFD compatibility allows precise speed control, energy savings, and seamless integration with automated systems. This variable frequency drive pump option expands your control possibilities while maintaining the GreenLine’s reliable mechanical design and chemical handling capabilities.
Advanced GreenLine options for specialized applications
Double diaphragm pump protection with leak detection
The GreenLine leak detection pump option provides double diaphragm pump protection with continuous monitoring of diaphragm integrity. This dual-diaphragm system includes a pressure gauge and switch that alerts operators to potential diaphragm failure before costly product loss or equipment damage occurs. The pump’s leak detection feature gives you superior protection and peace of mind in critical applications where chemical containment is essential.
