Ultrachem ANSI dimensional magnetically driven pumps are designed to withstand the toughest process applications, and are constructed on the basis that "extreme situations call for extreme measures".
Ultrachem ANSI dimensional magnetically driven pumps are designed to withstand the toughest process applications, and are constructed on the basis that "extreme situations call for extreme measures".
Available through liquids handling specialists Michael Smith Engineers, Ultrachem pumps use a ductile iron casting and incorporate a Tefzel (ETFE) lining for high corrosion resistance.
These pumps deliver flows up to 75m3/h and heads to 100m, and incorporate a modified concentric volute to equalise 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, resulting in decreased pressure on the impeller.
Straightening vanes in the suction prevent the possibility of prerotation 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 minimising 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 glass fibre.
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 4-20mA output for use with a PLC.
The UC1516 model has a 1.5in ANSI suction, 1in ANSI discharge and a 162mm diameter impeller.
Maximum flow for this model is 30m3/h at 2900rev/min and the maximum differential head is 37m.
The UC326 offers a 3in ANSI suction, 2in ANSI discharge, 162mm diameter impeller and a maximum flow of 58m3/h.
The maximum differential head for this model is 35m.
The UC1518 has a 1.5in ANSI suction, 1in ANSI discharge, 206mm-diameter impeller and offers a maximum flow of 29m3/h and a maximum differential head of 67m.
All models are suitable for use with frequency inverters to offer a maximum flow and maximum differential head of 75m3/h and 100m.
