Motor Technology to supply TPM pumps

Fuji Techno Industries has appointed Motor Technology of Stockport as its sole European agents to provide sales and servicing of its specialist triplex plunger metering (TPM) pumps. TPM pumps are used in metering applications where a predetermined volume of liquid is pumped into a process or system with a very high degree of accuracy - better than 0.1 per cent in the case of water - even under variable pumping conditions like discharge pressure, temperature or viscosity of fluid.

The pumps have three cams that discharge the required volume of fluid from three cylinders at a continually constant rate. The design of each plunger incorporates six phases of movement at increments of 60deg within one revolution of its respective cam. The flow rate at the suction side is kept constant to minimise the possibility of cavitations and pulsation. The pump's cams are designed to enable the plungers to deliver a constant volume of fluid from the three cylinders.

Fuji Techno's TPM pumps can handle all fluid viscosities from 0.01 to 1,000-p and from 0 to 30,000psi. They cover a range of pumping requirements from 0.002 to 1,300gph. The pumps can be specified with solvent- and corrosion-resistant pump heads and cooling or heating jackets can be supplied to enable liquids of low and high temperature to be processed (-30 to 200C). Typical applications include chemical, pharmaceutical, polymer, aerospace, water-treatment and paper industries.

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.
