Product Description
Pulsatron Series HV Metering Pump
The Pulsatron Series HV metering pump provides precise chemical dosing for high-viscosity liquids. Moreover, its positive-displacement diaphragm design supports reliable operation in demanding industrial applications.
Operators can manually adjust the stroke rate and stroke length. Alternatively, they can select optional 4–20 mA control or external pacing for automatic operation.
In addition, the pump can handle viscosities up to 20,000 cPs with suitable flooded-suction conditions. Therefore, it is ideal for thick chemicals that standard dosing pumps may struggle to handle.
High-Viscosity Chemical Dosing
Viscous chemicals do not flow as easily as water-like liquids. Consequently, they require suitable suction conditions and reliable valve operation.
The Pulsatron Series HV uses a liquid end designed for thick products. In addition, guided ball check valves help reduce backflow and improve priming.
Typical Chemicals
- Polymers
- Concentrated treatment chemicals
- Dyes and colourants
- Cleaning agents
- Process additives
- Selected oils and viscous liquids
However, users should always confirm the chemical viscosity, concentration and compatibility before selecting the pump. As a result, they can avoid material damage and poor dosing performance.
Key Benefits of the Pulsatron Series HV
The Pulsatron HV diaphragm metering pump offers several practical advantages:
- Handles viscosities up to 20,000 cPs
- Provides metering reproducibility within ±2%
- Delivers flow rates up to 37.9 litres per hour
- Provides pressure capabilities up to 10 bar
- Offers a wide 100:1 turndown ratio
- Includes manual stroke-rate control
- Includes manual stroke-length control
- Supports optional 4–20 mA automatic control
- Supports optional external pacing
- Includes an external stop function
- Uses guided ball check valves
- Supports continuous-duty operation
- Offers water-resistant construction
- Includes thermal overload protection
- Uses a sealless diaphragm liquid end
Moreover, these features support flexible pump operation. As a result, the Series HV provides accurate dosing with fewer manual adjustments.
Flow and Pressure Performance
Pulsafeeder offers five Series HV models. Therefore, users can select a pump according to the required flow and pressure.
The overall performance range includes:
- Flow capacity: 1.9 to 37.9 litres per hour
- Daily capacity: 12 to 240 gallons per day
- Maximum pressure: Up to 10 bar
- Maximum pressure in PSI: Up to 150 PSI
- Turndown ratio: 100:1
- Metering reproducibility: Within ±2% of maximum capacity
However, higher-flow models operate at lower maximum pressures. Therefore, users must consider both flow and discharge pressure during pump selection.
In addition, chemical viscosity may affect actual pump performance. Consequently, users should confirm operating conditions before choosing the final model.
Manual Stroke Control
The Series HV includes manual control as standard.
Stroke-rate adjustment changes the number of pumping strokes per minute. Meanwhile, stroke-length adjustment changes the volume delivered during each stroke.
Together, these adjustments provide an overall turndown ratio of 100:1. Consequently, operators can fine-tune the chemical feed rate according to process demand.
Moreover, manual adjustment provides flexibility during commissioning. However, users should calibrate the pump under actual operating conditions for accurate results.
Optional Automatic Control
The Pulsatron Series HV can accept a direct 4–20 mA input. Therefore, it can automatically adjust its output according to an external process signal.
Compatible Control Devices
The pump can connect to:
- Flow meters
- Process controllers
- PLC systems
- pH controllers
- Conductivity controllers
- Water-treatment control panels
As the input signal changes, the pump changes its stroke rate. As a result, chemical dosing can follow changing process conditions.
In addition, external pacing is available. For example, a water meter can send pulses according to the volume passing through the system.
Consequently, the pump can dose chemicals in proportion to process flow.
Reliable High-Viscosity Operation
A flooded-suction arrangement is recommended for very thick liquids. This setup places the chemical supply above the pump inlet.
Therefore, gravity helps move the liquid into the pump head. Moreover, it reduces the risk of poor priming and insufficient chemical flow.
Installation Factors to Consider
- Chemical viscosity at operating temperature
- Suction-line length
- Suction pipe diameter
- Chemical tank location
- Required flow rate
- Discharge pressure
In addition, users should keep suction lines as short as possible. Consequently, the pump can draw viscous liquids more effectively.
Temperature can significantly affect viscosity. Therefore, UAE outdoor installations should consider seasonal and daytime temperature changes.
Chemical-Resistant Material Options
The Series HV offers several wetted-material configurations.
Available options may include:
- Glass-filled polypropylene
- PVC
- PTFE valve components
- 316 stainless-steel valve balls
- Alloy C valve balls
- CSPE or Viton seals
- PTFE-faced diaphragm construction
Therefore, the pump can handle many industrial chemicals. However, users must confirm material compatibility before ordering.
Moreover, both chemical concentration and temperature can affect compatibility. Consequently, these details should form part of the pump-selection process.
Pulsatron Series HV Applications in the UAE
The Pulsatron Series HV metering pump suits many UAE industries.
Common applications include:
- Polymer dosing in wastewater treatment
- Sludge dewatering systems
- Industrial water treatment
- Chemical processing plants
- Manufacturing facilities
- Paint, ink and coating processes
- Cooling-water treatment
- Non-hazardous oil and gas utility systems
For example, wastewater plants can use the pump for controlled polymer dosing. In addition, manufacturing facilities can use it for dyes, cleaning agents and process additives.
However, hazardous locations require the correct hazardous-area certification. Therefore, users should select a suitable certified pump for classified installations.
