Product Description
FTI SF Series
The FTI SF Series consists of sealless drum and barrel pumps designed for transferring chemicals from drums, barrels, totes and other containers. Therefore, the range provides a practical solution for applications where chemical compatibility, contamination control and dependable operation are important.
Available models include polypropylene, pure PVDF, combined PP/PVDF and 316 stainless-steel constructions. Moreover, users can select high-flow or high-head impellers according to the required transfer rate and discharge pressure.
SF Series Sealless Drum Pump Design
The sealless construction removes the mechanical shaft seal found in many conventional pumps. Consequently, there is no seal face requiring routine replacement during normal service.
This design is particularly useful for Diesel Exhaust Fluid because DEF can crystallise when exposed to air. Finish Thompson explains that crystallisation around a mechanical seal can damage the seal and create leakage or additional maintenance.
Therefore, the pump range supports cleaner and more dependable transfer of suitable chemicals when correctly selected for the liquid.
High-Flow and High-Head Impellers
The range provides two principal hydraulic options:
- High-flow models: Up to 37 gpm or 140 lpm
- High-head models: Up to 24 gpm or 91 lpm
- Maximum high-flow head: Up to 50 ft or 15 m
- Maximum high-head performance: Up to 83 ft or 25 m
Therefore, high-flow pumps suit faster container emptying. In contrast, high-head configurations support longer hoses, greater elevation or higher system resistance.
However, actual performance varies according to the selected motor, liquid viscosity, specific gravity and installation conditions.
Key Features
The FTI SF Series provides several practical features:
- Sealless chemical-transfer construction
- High-flow and high-head impeller options
- Slim 41 mm tube for smaller bung openings
- Maximum viscosity up to 1,200 cP
- Maximum specific gravity up to 2.0
- Interchangeable electric and air motors
- Integral strainer on high-flow versions
- Built-in hose and electrical-cord clips
- Several available tube lengths
- Multiple chemical-resistant materials
- SFM-DEF model for DEF and AdBlue
- FDA-compliant material options on the SFS model
Together, these features allow the pump range to serve varied container-to-container fluid-transfer applications.
SFM-DEF Diesel Exhaust Fluid Pump
The SFM-DEF is specifically configured for transferring DEF or AdBlue from drums and barrels.
It includes a polypropylene tube, 316 stainless-steel shaft, EPDM O-rings and a polypropylene impeller. In addition, its 19 mm discharge and hose connection suit common DEF transfer arrangements.
With an electric motor, the high-flow version delivers up to 140 lpm. Alternatively, the high-head electric configuration provides up to 91 lpm and 25 metres of head.
Consequently, users can select either rapid filling or greater delivery pressure according to the installation.
Chemical-Resistant Tube Materials
The available pump-tube constructions include:
- Polypropylene
- Polypropylene and PVDF combinations
- Pure PVDF
- 316 stainless steel
Therefore, the range can support many acids, bases, cleaners, plating solutions and water-treatment chemicals.
However, users must verify material compatibility against the precise liquid concentration, temperature and operating conditions before selecting a model.
Operating Temperature and Tube Lengths
Maximum liquid temperature depends on the selected construction:
- Polypropylene: Up to 79°C
- Selected PP/PVDF models: Up to 79°C
- PVDF: Generally up to 60°C
- 316 stainless steel: Up to 100°C
Available tube lengths include 69, 102, 122, 137, 152 and 183 cm. Consequently, users can match the pump with different drum, barrel, tote and container depths.
Interchangeable Electric and Air Motors
The FTI SF Series is compatible with selected ODP, TEFC, explosion-proof and pneumatic motor options.
For example, variable-speed motors allow operators to regulate flow during container filling. Meanwhile, air motors provide a non-electrical drive option where a suitable compressed-air supply is available.
However, the selected motor affects flow, head, viscosity capability and hazardous-area suitability. Therefore, the motor and pump tube should be specified as one complete assembly.
FTI SF Series Applications in India
The drum and barrel pump range may support applications across India such as:
- Diesel Exhaust Fluid and AdBlue transfer
- Acid and base transfer
- Water-treatment chemicals
- Cleaning chemicals
- Plating solutions
- Kidney dialysis solutions
- Corrosive chemical handling
- Drum and barrel emptying
- Container-to-container transfer
- General industrial chemical handling
For example, the SFM-DEF can transfer DEF into vehicle storage tanks. Similarly, a chemically compatible PVDF model can support suitable corrosive-fluid duties in chemical-processing or water-treatment facilities.
Selecting the Correct SF Series Pump
Correct selection depends on:
- Liquid name and concentration
- Required flow and discharge head
- Fluid viscosity
- Specific gravity
- Operating temperature
- Container depth
- Pump-tube material
- Motor type and electrical supply
- Hazardous-area requirements
- Hose and nozzle configuration
Therefore, users should select the FTI SF Series according to the complete transfer duty. Otherwise, incompatible materials or insufficient motor power may reduce performance, reliability and service life.
