SF Series (High Flow)
When your industrial process involves handling aggressive chemicals, standard pumping solutions often fail prematurely. The SF Series high flow barrel pumps are specifically engineered to tackle the most demanding environments, providing a reliable mechanism for transferring acid, base, and highly corrosive fluids. These pumps excel in medium viscosity applications, ensuring that your production line remains uninterrupted even when dealing with complex chemical compositions.
We designed this series with a focus on durability and high-volume throughput. Whether you are managing IBCs, large tanks, or standard 200-liter drums, the SF Series adapts to your specific storage configuration. By integrating a double fan design, these pumps achieve a significant increase in discharge capacity, making them the preferred choice for facilities requiring rapid fluid movement without compromising the integrity of the pump components.
Advanced Engineering for Corros-ive Fluid Management
Handling corrosive fluids promising strong performance requires more than just a sturdy casing; it requires precise material science. The SF Series utilizes high-grade Polypropylene and PVDF body options to resist chemical degradation. If your application involves slightly less aggressive but still thermally demanding liquids, our 316SS options provide the necessary thermal stability up to 100°C. This versatility allows engineers to select a pump that matches the specific pH and temperature profile of their medium.
The packingless design is a critical feature for safety and maintenance. By eliminating traditional seals that are prone to leakage, we reduce the risk of environmental contamination and hazardous exposure. This design philosophy ensures that the internal pressure remains contained, significantly extending the service life of the pump even under continuous operation in harsh chemical plants or laboratory settings.
High Flow Performance and Technical Specifications
Efficiency in fluid transfer is measured by flow rate and head pressure. The SF Series is a powerhouse in its class, capable of reaching a maximum flow rate of 140 l/min. This high-flow capability is achieved through specialized fan configurations. Depending on your specific needs, you can choose between different fan options—some optimized for maximum volume (high flow) and others designed to overcome resistance in longer piping networks (high outlet pressure).
Below are the core technical parameters that define the SF Series capabilities:
- Viscosity Limit: Capable of handling fluids up to a maximum of 1,200 cps.
- Density Range: Optimized for fluids with a maximum density of 1.83 g/cm³.
- Pressure Head: Delivers a maximum head of 15 meters for effective vertical lifting.
- Physical Footprint: Compact 51 mm body diameter, ideal for tight spaces in drums or containers.
Versatile Motor and Power Configurations
Every industrial setup has unique electrical and safety requirements. We understand that a standard electric motor might not be suitable for every zone, especially in volatile environments. Therefore, the SF Series offers a wide range of motor options, including air-driven, standard electric, and ex-proofer electric motors. This flexibility ensures that the pump can be safely integrated into ATEX-rated zones or simple workshop environments alike.
Choosing the right motor is not just about power; it is about compatibility with your existing infrastructure. An air-driven motor is excellent for preventing sparks in highly flammable atmospheres, while the electric options provide a cost-effective solution for standard chemical transfers. Our team can help you calculate the required torque and power based on your specific fluid viscosity and discharge height.
Material Selection: Polypropylene vs. PVDF vs. 316SS
Selecting the wrong material can lead to catastrophic pump failure within hours. The SF Series provides three distinct paths based on your chemical compatibility needs. Polypropylene is our go-to for many standard acids and bases, offering excellent cost-to-performance ratios and temperature resistance up to 66°C. It is the most economical choice for many routine industrial cleaning and transfer tasks.
For more aggressive chemical profiles, the PVDF option extends your temperature resistance to 71°C. PVDF is renowned for its superior resistance to strong oxidizing agents. If your process involves high-temperature fluids, our 316SS (Stainless Steel) variant is the ultimate solution, maintaining structural integrity and chemical resistance up to 100°C. We recommend a thorough chemical compatibility check before finalizing your order.
Optimizing Your Transfer Process
To get the most out of your SF Series pump, consider the entire fluid path. The pump does not operate in isolation; the diameter of your suction and discharge hoses, the length of the pipe run, and the presence of bends all affect the 140 l/min potential. Using appropriately sized hoses prevents cavitation and ensures the double fan design can operate at its peak efficiency.
We often see users attempting to pump fluids exceeding the 1,200 cps limit, which puts unnecessary strain on the motor. If your fluid is thicker, we can discuss alternative pumping technologies. Proper maintenance of the pump—specifically checking for any debris in the suction line—will ensure that the high-flow performance remains consistent over years of service.
Comparison of SF Series Configurations

|---|---|---|---|
| Max Temperature | 66°C | 71°C | 100°C |
| Chemical Resistance | High (Acids/Bases) | Very High (Oxidizers) | Extreme (Thermal/Corrosive) |
| Primary Use Case | General Industrial | Aggressive Chemical | High-Temp Processing |
Frequently Asked Questions
Can the SF Series handle fluids with high solids content?
The SF Series is optimized for medium viscosity fluids and clean liquids. While it is incredibly robust for corrosive fluids, high concentrations of abrasive solids can wear down the internal components and reduce the flow rate. We suggest checking the particle size of your medium before implementation.
What is the difference between the high flow and high pressure fan options?
The high flow fan is designed to move the maximum volume of liquid per minute, ideal for rapid emptying of tanks. The high pressure fan is engineered to provide more “push,” which is necessary if you are pumping through long, narrow, or vertically ascending pipe networks.
Is the pump suitable for use in ATEX zones?
Yes, by selecting our ex-proof electric motor options, the SF Series can be safely utilized in environments where explosive atmospheres may be present. Always specify your zone requirements during the quotation process.
