Three-Phase Electronic Contactors are designed for applications demanding fast and precise switching. It utilizes power chips with new low thermal expansion technology. This unique power chip design ensures high switching capacity and long life. These are burst fired for reduced emission, have status indicators and accept universal control voltages. The units are rail mountable, complete with heat sink and require no additional components. These are used in heaters, solenoids, transformers and motors. They have varistor protections and are quick and easy to install.
Three-Phase Transducers are equipped with three voltage inputs with common L terminal, three floating current inputs and with 20 mA current. Three phase transducers provide a true indication of power factor only when balanced load conditions prevail.
Three-Screw Pumps are suitable for group 1 liquid types. Three-screw pumps have only one bearing, internal or external, adjacent to the coupling. Three-screw pumps are available in either single or double end construction. Three-screw pumps are generally lined construction. Three-screw pumps are widely used in pumping fuel oil of various viscosities. Three-screw pumps generate some axial loads. Three-screw pumps are designed to give pulsation-free delivery. Three-screw pumps are commonly used for machinery lubrication, powering hydraulic machinery and conveying high temperature viscous products in refineries.
