Vanton Introduces Thermoplastic Centrifugal Pump

Vanton Pump has introduced a Sump-Gard thermoplastic centrifugal pump for use in effluent collection and evacuation and the transfer and circulation of chemicals or waste. The SGK-2700 pump, which handles flows to 4,500 litres per minute (1,200 gallons per minute) at heads to 60m (200ft), minimises maintenance costs and maximises the meantime between repairs.

All wetted components are moulded of solid polypropylene, PVDF or CPVC to eliminate chemical attack associated with the pumping of process fluids, plant effluents and industrial/municipal water and waste streams, while minimising abrasion. Since all wetted surfaces are chemically inert, the pumps are also rated for handling reagent-grade chemicals, high-purity water and other fluids that must remain contamination free. The alloy shaft, which is isolated from fluid contact by a thick-sectioned thermoplastic sleeve, transfers torque from a 93kW (125hp) motor and can employ a balanced 356mm (14in)-diameter impeller.

The pump's large-diameter cantilevered shaft eliminates the necessity for any immersed bearings and permits dependable operation for short or extended periods of dry-run operation, with no damage to the pump. SGK series pumps weigh less than pumps of equivalent capacity constructed of stainless steel, Hastelloy, Monel or other metal alloys, facilitating installation and maintenance, according to the company. Vanton also offers other vertical pump configurations, a line of horizontal centrifugal thermoplastic pumps (including seal-less magnetically driven pumps), seal-less peristaltic pumps and integrated non-metallic tank/pump systems.

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.
