Product Description
PulsaPro 680 Metering Pump
The PulsaPro 680 Metering Pump is a positive-displacement, hydraulically balanced diaphragm pump for accurate chemical dosing. Moreover, its leak-free design separates the process liquid from the drive mechanism, which supports safe and dependable operation.
The pump delivers flow rates up to 38.2 GPH or 144.6 LPH. In addition, selected configurations operate at pressures up to 3,100 PSI or 213.7 bar. Therefore, the PulsaPro 680 suits demanding chemical-injection duties where precision, containment and long service life are essential.
Precise and Repeatable Chemical Dosing
The PulsaPro 680 provides steady-state accuracy of ±0.5% of the selected set point. Moreover, it offers repeatability of ±0.5% and linearity of ±0.5% across a 10:1 turndown range.
Manual stroke adjustment provides 0.1% setting resolution. Alternatively, users can select electronic stroke-length control with five times finer resolution. As a result, operators can adapt chemical output closely to changing process demand.
Key Benefits of the PulsaPro 680
- Maximum flow up to 144.6 LPH
- Maximum pressure up to 213.7 bar
- Accuracy and repeatability of ±0.5%
- Linear performance over a 10:1 turndown
- Hydraulic diagnostic performance window
- Externally adjustable hydraulic bypass valve
- Push-button hydraulic priming and air removal
- Low NPIP requirement of 5 PSI or 0.31 bar
- Four-bolt tie-bar construction
- Three-component check valves
- HYDRAtube, HYDRAcone and flat diaphragm options
- Manual or electronic stroke control
- PULSAlarm leak-detection options
- HypoValve automatic degassing option
- API 675, CE, ATEX and IECEx options
- Drinking-water-compliant configurations
- Five-year gear-train warranty
Together, these features support precise dosing and reliable hydraulic operation. Moreover, they help maintenance teams identify developing issues before they cause prolonged downtime.
Diagnostic Performance Window
The diagnostic window provides immediate visual information about hydraulic operation. For example, operators can observe oil condition, piston position and possible blockage conditions.
Therefore, technicians can begin troubleshooting without immediately dismantling the pump. As a result, the feature can shorten service time and support preventive maintenance.
Hydraulic Protection and Air Management
Unexpected restrictions can raise discharge pressure quickly. Consequently, the PulsaPro 680 includes an externally adjustable hydraulic bypass valve that protects the pump against over-pressurisation.
In addition, a push-button hydraulic priming and air-bleeding feature helps remove trapped air from the hydraulic system. Therefore, the pump can restore effective diaphragm movement more quickly after commissioning or service.
Meanwhile, the hydraulic performance valve maintains the correct diaphragm position. As a result, the pump requires only 5 PSI or 0.31 bar NPIP, although users must still check the complete suction system carefully.
Durable Wet-End Options
The PulsaPro 680 supports HYDRAtube, HYDRAcone and flat diaphragm designs. Therefore, users can select a wet end for standard chemicals, viscous products, shear-sensitive liquids or selected slurries.
Standard pump-head materials include:
- 316L stainless steel
- PVC
- Glass-filled PTFE
Additionally, application-specific materials include Alloy C, Alloy 20, Monel, duplex stainless steel, titanium and PVDF. Consequently, the pump can support a broad range of chemical-compatibility requirements.
Ball valves suit many standard applications. Alternatively, disc or slurry-valve arrangements can support higher flows or liquids containing suspended solids.
Temperature and Viscosity Capabilities
Suitable configurations handle fluid temperatures from approximately -23°C to 121°C. Moreover, the pump can handle viscosities up to 1,000 cP under appropriate inlet conditions.
However, viscous liquids increase suction losses. Therefore, users should confirm pipe diameter, liquid vapour pressure, acceleration losses and available inlet pressure before final selection.
Standards and Drinking-Water Compliance
The PulsaPro 680 complies with API 675 for controlled-volume metering pumps. In addition, CE, ATEX and IECEx configurations are available for applicable installations.
Moreover, WQA-certified NSF/ANSI/CAN 61 configurations support suitable drinking-water treatment processes. Consequently, the pump can serve both heavy industrial and municipal water applications.
PulsaPro 680 Applications in the UAE
The PulsaPro 680 suits:
- Oil and gas chemical injection
