Finish Thompson SP Self-Priming Magnetic Drive Pump
SELF-PRIMING, MAG-DRIVE PUMP RANGE EXTENDED
Available from MICHAEL SMITH ENGINEERS FTI SP pumps provide a fast, powerful, yet economical performance with optimum versatility and because of their innovative design and corrosion-resistant materials are able to withstand the rigours of the most challenging applications. SP pumps combine deep lift capabilities (up to 7.6 metres) and fast priming (5.5 metres in 90 seconds) with the important advantages of magnetic drive technology, such as no seals to replace, no leaks and the capability to run-dry without damage.
Features
* Polypropylene or PVDF construction
* Sealless mag drive
* Powerful neodymium magnets
* Close coupled with back pullout design
* Mounts to NEMA and IEC motor frames
* Replaceable shaft
* ISO 1940 G2.5 balancing
* CE certified
Capabilities
- Retains fluid for re-priming when shut off without a check valve
- Runs without damage in absence of continuous flow
- Provides up to 7.6 metres of lift
- Primes 4.6 metres in 90 seconds
- High working pressure up to 90 psi
- High specific gravity handling – over 1.8
- Maximum temperature:
Polypropylene – 82 deg C
PVDF – 104 deg C
Applications
- Sumps
- Underground storage tanks
- Rail cars
- Tanker trucks
- Over-the-wall applications
- Tanks with an opening on top
- Piping systems that tend to have trapped or entrained air
- When run dry protection is need
Thermoplastic Priming Chamber
Functions as a fluid reservoir and features molded-in “gooseneck” suction passage eliminating the need for internal check valves, integral fill and drain ports are standard. Available in GF-PP or CF-PVDF for optimal corrosion resistance
O Ring
Creates airtight seal between the inner volute and the “gooseneck” suction passage. Helps the pump maintain the vacuum required for proper priming
Multiple Connections
NPT or BSP threads, raised face adjustable flanges or union
Separator Plate
Acts as a barrier between the low velocity fluid reservoir and the high velocity area in the rear of the priming chamber. Openings allow liquid to flow to the impeller and discharge the air/liquid mixture created during priming back into the fluid reservoir
Inner Volute
Houses the rotating impeller. Special design allows air to be efficiently removed from the suction passages for fast priming
Multiple Impeller Diameters
Allows hydraulic requirements to be precisely met. Two piece impeller design allows impeller to be changed without having to replace inner drive
Run Dry System
The SP can run dry without damage when equipped with a chemical grade carbon busing in optimum operating conditions. This helps protect the pump from operator errors and system upsets
Easy Set Outer Drive
Measurement-free outer drive ensures optimum magnet alignment and easy motor installation
