ULTRAChem Features
ULTRAChem Capabilities
Maximum Allowable Horsepower
Do not exceed the maximum horsepower rating for the pump coupling. Refer to the chart below. Use the first six or seven charac-
ters from the model number listed on the label found on the motor adapter.
Maximum Working Pressure: 175 psi (12 bar)
Maximum Temperature:
250°F (121°C) (application dependent)
Minimum Temperature:
-20°F (-29°C)
Maximum Flow:
325 USgpm (74 m
3
/hr)
Maximum Head:
320 ft (98 m)
Maximum Viscosity:
200 cP
Solids:
Maximum particle size is 50 microns for slurries and 1/64” (.4 mm) for
infrequent particles. Maximum hardness is 80 HS. Maximum concentration
is 5% by weight. If solids are being pumped, it is recommended the pump
have the silicon carbide bushings and thrust washer.
The Finish Thompson ULTRAChem is a sealless, magnetically driven, ANSI dimensional, ETFE lined, chemical pump.
It has been specifically designed for corrosive chemical applications in a wide range of industrial services.
The ULTRAChem features a closed impeller, suction straightening vanes, balanced axial thrust with a rear sealing ring, balance holes
and balanced radial thrust due to the modified concentric volute shape.
The ULTRAChem uses standard silicon carbide shaft, thrust bearings and bushings (optional carbon bushings allow limited run dry
capabilities). All metallic components are steel or cast ductile iron.
High strength, rare earth neodymium boron iron magnets are used for maximum power and reliability. Finish Thompson’s patented
magnetic technology ensures an extraordinarily strong, secure coupling between the motor and pump.
The barrier consists of a precision molded carbon filled ETFE liner with an external woven-glass-filled vinyl ester for superior me-
chanical strength and elimination of eddy currents in the magnetic coupling. The sealless design virtually eliminates maintenance
and environmental emissions.
The Easy Set drive feature makes installation of the outer drive quick and easy. It eliminates the need for measuring and ensures that
the inner and outer magnets are perfectly aligned to transmit maximum power.
The ULTRAChem has drive hubs and motor adapters for a complete range of NEMA and IEC motor frames. The suction and dis-
charge flanges are drilled for both ANSI and ISO.
These features combine to provide our customers with a pump that offers a broad operating range with outstanding reliability due to
minimum hydraulic loads and premium materials of construction.
FTI’s ATEX compliant pumps meet Directive 94/9/EC for use in potentially explosive atmospheres.
