Product Description
Pulsafeeder GreenLine Chemical Transfer Pump
The Pulsafeeder GreenLine Chemical Transfer Pump is a mechanically actuated diaphragm metering pump for demanding chemical-transfer and dosing duties. Moreover, its rugged, compact construction supports continuous operation in harsh industrial environments.
The GreenLine range delivers flows from 3.2 to 824 GPH, or 12 to 3,120 LPH. In addition, selected models provide pressures up to 174 PSI or 12 bar.
Therefore, the pump suits water treatment, chemical processing, mining and manufacturing applications that require dependable chemical dosing.
Precise and Drift-Free Flow Control
Chemical processes require consistent dosing to maintain product quality and treatment performance. Consequently, gradual changes in the stroke setting can create process problems.
The GreenLine uses an auto-locking stroke-adjustment mechanism. Therefore, vibration and operating stresses do not gradually move the selected setting.
Operators can adjust the stroke from 0 to 100% in one complete revolution. Moreover, the adjustment provides 1% resolution for precise manual control.
As a result, users can set the required output and operate the pump without repeatedly locking or readjusting the mechanism.
Key Benefits of the GreenLine Pump
The GreenLine chemical pump offers several practical advantages:
- Flow capacities from 12 to 3,120 LPH
- Maximum pressure up to 12 bar
- Accuracy of ±2% of the set point
- 10:1 turndown ratio
- Auto-locking stroke adjustment
- One-percent stroke-setting resolution
- Suction lift up to 3 metres
- Viscosity handling up to 1,000 cPs
- Compact and lightweight gearbox
- Fully sealed, non-vented drive design
- Oil-bath lubrication
- Double-sided PTFE diaphragm
- Ceramic or stainless-steel check valves
- PVDF and 316L stainless-steel wet ends
- Optional diaphragm leak detection
- Optional variable-frequency drive
- NSF/ANSI/CAN 61 and NSF/ANSI 372 certification
Together, these features support consistent chemical dosing. Moreover, they can reduce maintenance intervention and long-term operating costs.
Flow and Operating Performance
The Pulsafeeder GreenLine provides the following operating capabilities:
- Flow range: 3.2–824 GPH
- Metric flow range: 12–3,120 LPH
- Maximum pressure: 174 PSI or 12 bar
- Stroke adjustment: 0–100%
- Adjustment resolution: 1%
- Accuracy: ±2% of the set point
- Turndown: 10:1
- Maximum suction lift: 10 feet or 3 metres
- Maximum viscosity: 1,000 cPs
- Process temperature: 0–45°C
- Ambient temperature: 0–45°C
However, maximum flow and pressure vary between GreenLine models. Therefore, users should select the pump according to the complete duty point rather than maximum capacity alone.
Durable PTFE Diaphragm Technology
The GreenLine uses a double-sided PTFE-faced, multi-layer composite diaphragm. Moreover, the DM7 model offers a solid PTFE diaphragm.
The PTFE surfaces provide strong chemical resistance. In addition, multiple sealing beads help prevent leakage around the diaphragm.
Pulsafeeder designs the composite diaphragm for more than one million operating cycles. Consequently, the pump can provide extended service life in continuous chemical-feed applications.
Contamination-Proof Gearbox
Dust, moisture and chemical vapours can damage conventional pump drives. Therefore, GreenLine uses a fully sealed and non-vented gearbox.
Oversized shielded bearings support the internal drive components. Meanwhile, oil-bath lubrication protects the moving parts and supports reliable torque transmission.
As a result, the pump suits humid treatment plants, dusty mining sites and demanding manufacturing environments.
Leak-Resistant Chemical Containment
The GreenLine uses several containment barriers. For example, selected PVDF configurations include secondary O-ring seals and a double-barrier check-valve assembly.
In addition, secure diaphragm-sealing technology helps prevent chemical spray and pressure leakage.
Consequently, the design protects personnel, surrounding equipment and the environment. However, users must still select materials that suit the exact chemical and operating temperature.
Wet-End Material Options
Available wet-end configurations include:
- PVDF with ceramic check balls
- 316L stainless steel with stainless-steel check balls
- PTFE or FKM O-ring options, depending on the model
- Composite PTFE diaphragms
- Solid PTFE diaphragm for the DM7
Therefore, users can configure the GreenLine for many acids, alkalis, disinfectants and industrial chemicals.
Moreover, standard connections include FNPT and ANSI flanged arrangements. Connection sizes range from ½ inch to 1½ inches, depending on the selected model.
Optional Process-Control Features
Variable-Frequency Drive
A VFD allows users to adjust motor speed. Consequently, it expands the operating range and supports remote flow control.
Double-Diaphragm Leak Detection
The leak-detection option uses two diaphragms, a pressure gauge and a pressure switch. Therefore, it alerts operators to diaphragm damage before significant chemical loss occurs.
Degas Bleed Valve
Models DM1 to DM6 can include a degas bleed valve for chemicals that release gas. As a result, the pump can maintain prime and avoid reduced output when dosing products such as sodium hypochlorite.
