Ultrachem ANSI dimensional magnetically-driven pumps have been designed with extreme reliability in mind and are now part of the extensive range of pumps available through Michael Smith Engineers.
Designed on the basis that "extreme situations call for extreme measures", these Ultrachem pumps are based on a ductile iron casting and incorporate a Tefzel (ETFE) lining for high corrosion resistance.
The casing meets ANSI/ASME B73.1M nozzle loads.
These chemical pumps, which deliver flows up to 75 M3 per hour and heads to 100 metres, incorporate a modified concentric volute to equalize pressure across the entire flow range.
The resultant minimal hydraulic radial thrust loads produced, lead to reduced wear on the pump's components.
This, combined with a rear sealing ring and holes in the impeller, balance the hydraulic axial thrust and thus decrease pressure on the impeller.
The straightening vanes in the suction prevent the possibility of pre-rotation under low flow conditions and also reduce turbulence on the impeller which enhances operation at low flow rates.
Sintered silicon carbide dual bushings ride evenly on the shaft to provide optimum alignment while the spiral bores on the bushings help to flush and lubricate the shaft during operation.
The impeller is driven by powerful neodymium magnets to provide leak-free operation and eliminate the possibility of environmental emissions, whilst also minimizing maintenance.
A casing drain is standard for all these pumps and maintenance is simplified by the back- pull-out design.
Baseplates can be provided in steel or fibre glass.
The option of a digital power monitor is also available to detect over and under load conditions.
This protects against dry running and includes a current transducer and a 4-20 mA output for use with a PLC.
The UC1516 model has a 11/2 " ANSI suction, 1" ANSI discharge and a 162 mm diameter impeller.
Maximum flow for this model is 30m3 /hour at 2900 RPM and the maximum differential head is 37 metres.
The UC326 offers a 3" ANSI suction, 2" ANSI discharge, 162 mm diameter impeller and a maximum flow of 58m3 / hour.
The maximum differential head for this model is 35 metres while the UC1518 has a 11/2" ANSI suction, 1" ANSI discharge, 206 mm diameter impeller and offers a maximum flow of 29m3 /hour at a maximum differential head of 67 metres.
All models are suitable for use with frequency inverters to offer a maximum flow and maximum differential head of 75m3 /hour and 100 metres.
