Verderflex Peristaltic Pumps - Not Just for Slurry

By design, the peristaltic pump is ideal for the dependable handling of abrasive, corrosive, viscous, high density and high solid content fluids. It thrives in those applications where other types of pump fail. Water and waste water industries, mining and chemical processing are all prime markets for this workhorse. But being equal to the tough demands of these applications is far from its only strength. The peristaltic pump can also be extremely versatile.

Different hose and tube options allow this pump to handle an exceptionally wide range of fluids, there’s also a huge choice of flow rates and pressures to suit almost every application. And perhaps somewhat overshadowed by its dominance in heavy-duty slurry and sludge handling, is the peristaltic pump’s eminent suitability for handling shear sensitive products. It has a smooth, squeezing action that makes it ideal for use with flocculants, sensitive polymers and fragile cell cultures.

The growing awareness of the peristaltic pump’s wider potential is leading to its increased use in less arduous fields of application. It is regularly specified by the printing and packaging industries in place of air diaphragm pumps as it is gentle on the product but still able, for example, to handle viscous metallic inks. The food, drink and pharmaceutical industries are also regularly installing this type of pump. This is because the pumped product is isolated from the workings, there’s no danger of contamination and it’s easy to sterilise.

Another key factor in the rising popularity of the peristaltic pump is its fit-and-forget quality. Its lack of valves, seals and glands makes it inexpensive to maintain. Indeed the only replacement part on a peristaltic pump is the hose or tube, a relatively low cost item that is easily exchanged. These are important qualities as companies strive to optimise production processes and minimise costly downtime.

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.
