Product Description
PulsaPro 7120 Metering Pump
The PulsaPro 7120 Metering Pump is a positive-displacement hydraulic diaphragm pump designed for precise chemical dosing. Moreover, its leak-free wet end separates the process liquid from the drive mechanism.
The pump delivers flow rates up to 243 GPH or 920 LPH. In addition, selected configurations operate at pressures up to 3,100 PSI or 213.7 bar.
Therefore, the PulsaPro 7120 suits critical dosing duties in oil and gas, petrochemical, chemical-processing, power-generation and water-treatment facilities.
Accurate Chemical Metering
The PulsaPro 7120 provides steady-state accuracy of ±0.5% of the selected set point. Moreover, it maintains linear performance across a 10:1 turndown range.
Manual stroke adjustment provides 0.1% setting resolution. Alternatively, users can select an electronic stroke-length controller with substantially finer adjustment.
As a result, operators can match chemical output closely with changing process demand. Furthermore, the full-motion stroke mechanism supports linear flow adjustment from 0% to 100%.
Key Benefits of the PulsaPro 7120
The PulsaPro 7120 provides several operational advantages:
- Flow capacity up to 920 LPH
- Pressure capability up to 213.7 bar
- Steady-state accuracy of ±0.5%
- Repeatability of ±0.5%
- Linear performance over a 10:1 turndown
- Manual or electronic stroke-length control
- Hydraulic diagnostic viewing window
- Externally adjustable bypass valve
- Push-to-purge hydraulic air removal
- Low NPIP requirement of 5 PSI or 0.31 bar
- Four-bolt tie-bar construction
- Three-component check valves
- HYDRAtube or flat diaphragm wet ends
- Multiple chemically resistant materials
- API 675, CE, ATEX and IECEx options
- Certified drinking-water configurations
- Five-year gear-train warranty
Together, these features support accurate chemical injection and long-term dependability. Moreover, they simplify troubleshooting and protection during unexpected process changes.
Immediate Hydraulic Performance Visibility
The hydraulic diagnostic window allows operators to observe oil condition and hydraulic operation.
Therefore, maintenance teams can identify abnormal oil appearance, air accumulation or operational changes more quickly. As a result, they may spend less time dismantling equipment during initial troubleshooting.
Moreover, immediate visual information supports preventive maintenance. Consequently, users can respond before a small hydraulic issue causes extended downtime.
Push-to-Purge Hydraulic System
Air trapped within a hydraulic system can reduce pumping efficiency. Therefore, the PulsaPro 7120 includes a push-to-purge button for on-demand air removal.
The operator can purge unwanted air without completing a complicated service procedure. As a result, the pump can restore effective hydraulic performance more quickly.
In addition, efficient hydraulic operation reduces wasted motor energy. Consequently, the pump maintains more consistent diaphragm displacement.
Overpressure Protection
Unexpected valve closures or process restrictions can raise discharge pressure rapidly. Therefore, the pump includes an externally adjustable hydraulic bypass valve.
The valve protects the pump against system overpressure. Moreover, users can adjust the setting externally when process conditions change.
Consequently, operators can adapt the pump without extensive internal dismantling. However, the complete dosing system should still include correctly designed pressure protection.
Hydraulic Performance Valve
The hydraulic performance valve maintains the correct diaphragm position throughout operation. Therefore, it supports controlled diaphragm movement and consistent liquid displacement.
In addition, the design allows a low required net positive inlet pressure of 5 PSI or 0.31 bar. As a result, the pump can suit applications with challenging inlet conditions.
However, users must still confirm suction lift, liquid vapour pressure, acceleration losses and pipe restrictions during selection.
Durable Wet-End Designs
The PulsaPro 7120 offers HYDRAtube, flat and other diaphragm configurations. Moreover, available pump-head materials include:
- 316L stainless steel
- Glass-filled PTFE
- PVC
- Other application-specific materials
Ball check valves are standard for many applications. Alternatively, disc valves suit slurry solutions or higher flow requirements.
Therefore, users can configure the wet end according to chemical compatibility, temperature and solids content.
Temperature and Viscosity Capabilities
Suitable configurations handle fluid temperatures from approximately -23°C to 121°C. Meanwhile, ATEX configurations have model-specific temperature limits.
The pump can also handle viscosities up to 1,000 cP under suitable conditions. However, viscous liquids increase suction losses.
Therefore, users should confirm pipe diameter, inlet pressure, check-valve design and pump speed before ordering.
