Product Description
FTI SP Series Self-Priming Pumps
The FTI SP Series consists of horizontal, sealless magnetic-drive centrifugal pumps designed for self-priming chemical-transfer applications. Therefore, the pumps can draw liquid from tanks, sumps and containers positioned below the pump without requiring a conventional mechanical shaft seal.
Finish Thompson offers SP10, SP11, SP15 and SP22 models in polypropylene or PVDF construction. Across the complete range, published performance extends to approximately 57.5 m³/h of flow and 50 metres of head.
SP Series Sealless Magnetic-Drive Design
A magnetic-drive arrangement transfers motor torque through a sealed containment barrier. Consequently, no rotating shaft passes through the pump casing.
This sealless design removes the conventional mechanical seal and its associated leakage point. Moreover, it can reduce seal replacement and routine maintenance when handling compatible corrosive chemicals.
Key Features of FTI SP Series Pumps
- Self-priming centrifugal operation
- Sealless magnetic-drive construction
- Flow range up to 57.5 m³/h
- Maximum head up to 50 m
- Suction lift up to 7.6 m
- Priming from 5.5 m in approximately 90 seconds
- Working pressure up to 6.2 bar
- Polypropylene or PVDF construction
- Maximum specific gravity above 1.8
- Viscosity capability above 50 cP
- NPT, BSP, flange and union connections
- NEMA and IEC motor compatibility
- Back pull-out maintenance design
- Five-year warranty
- CE, UKCA and EAC certification
Together, these features allow the FTI SP Series to support demanding chemical-transfer systems while simplifying operation and maintenance.
Fast-Priming Chemical Pump Performance
The pump casing retains liquid after shutdown, allowing the unit to re-prime without an external check valve. Therefore, repeated starting can be simpler in installations where the liquid level remains below the pump.
Finish Thompson states that suitable configurations can prime from a depth of 5.5 metres in approximately 90 seconds. In addition, the complete range can lift fresh, cold water from depths up to 7.6 metres under suitable conditions.
Polypropylene and PVDF Pump Construction
Polypropylene models handle compatible liquids at temperatures up to approximately 82°C. Alternatively, PVDF versions support temperatures up to approximately 104°C and provide different chemical-resistance characteristics.
Available shaft materials include ceramic, Hastelloy C and silicon carbide. Meanwhile, bushing options include carbon, PTFE, alumina ceramic and silicon carbide, depending on the pump model. Therefore, users can configure the pump around the liquid chemistry and operating conditions.
SP10, SP11, SP15 and SP22 Models
The range includes:
- SP10: 1-inch connections and up to 12.2 m³/h at 2,900 RPM
- SP11: 1.5-inch connections and up to 24 m³/h at 2,900 RPM
- SP15: 1.5-inch connections and up to 25.8 m³/h at 2,900 RPM
- SP22: 2-inch connections and up to 47.9 m³/h at 2,900 RPM
Higher series maximums may apply at 3,450 RPM. Therefore, engineers should select the exact model from its performance curve at the required motor frequency and speed.
Self-Priming Pump Connections and Motors
Depending on the model, connection options include NPT, BSP, adjustable flanges and union connections. Moreover, the pumps mount to compatible NEMA and IEC motor frames.
The close-coupled design reduces installation space, while the back pull-out arrangement improves access to internal components. Consequently, technicians can service the hydraulic assembly without unnecessarily disturbing the connected piping.
UAE Applications for SP Series Pumps
The FTI SP Series may support:
- Rail-car unloading
- Chemical tanker unloading
- Bulk-storage tank transfer
- Sump and reservoir pumping
- Below-grade storage tanks
- Over-the-wall pumping
- Rinse-water transfer
- Electroplating and anodising
- Chemical-processing systems
- Corrosive wastewater transfer
For example, an SP pump can draw chemicals from a below-grade tank. Similarly, it can transfer rinse water or process chemicals from a sump into a treatment or storage system.
Selecting an FTI Self-Priming Pump
Correct selection depends on:
- Required flow and total head
- Vertical suction lift
- Chemical concentration
- Liquid temperature
- Viscosity and specific gravity
- Available NPSH
- Construction material
- Shaft and bushing materials
- Connection standard
- Motor voltage, frequency and speed
Therefore, users should configure the FTI SP Series around the complete hydraulic and chemical duty. Otherwise, excessive suction lift, incorrect materials or unsuitable piping may prevent reliable priming or reduce component life.
