SMVector Drives for Pumping Applications

No challenge is too great or single application too small. From industrial plants to OEMs to municipal water and wastewater treatment facilities, Lenze pump solutions are hard at work. Versatile and robust, our industrial drives and controls are cost-effective and low-maintenance. Our focus is on variable speed flow and pressure control so whatever your specific application requires, Lenze has the drives and controls to match form, fit and function.

Centrifugal pumps
Centrifugal, or Variable Torque pumps, are used in a wide range of commercial, industrial and municipal applications. Throttling valves are a common flow control method. Compared to a throttling valve, the lower power requirements of the SMVector VFD provide a greater energy savings. Operating at 75% flow reduces power demand by over 50% with an SMVector Drive, while a throttling valve requires about 90%.

Typical applications
•Chilled and Hot Water Pumps
•Condenser Water Pumps
•Booster Pumps
•Potable Water Pumps
•Chemical Pumps

Constant Torque pumps
Most Constant Torque pumps are also referred to as Positive Displacement (PD) Pumps. Using a VFD in these applications eliminates waste as the VFD tightly controls the volume pumped. While most VFDs are close to 100% starting torque, the SMVector Series offers 200% starting torque, allowing you to overcome the initial load. As a result, you can decrease the size of motor you are using, thus reducing the cost of the application.

Typical applications
•Metering Pumps
•Dosing Pumps
•Pumping highly viscous fluids or highly frictional loads
•Gentle fluid handling

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
