    Impellers

    The OK Electrical Industry patented POWER MIXER can be mounted on the volute of all
    OK electrical Industry “ZSP” pumps. Prior to the start of each pumping cycle, it transforms the pump into a powerful mixer, providing automatic debris sludge. Hereby it prevents the buildup of sludge banks and debris on the sump floor, as well as the formation of floating crusts. Offering a considerably cleaner station environment, it also provides a high degree of oxygenation, leading to a virtually odor-free pump station.

    Automatic Level Control

    For dewatering and drainage, the Pumps can be automatically regulated with the level control system. This system, and ok electrical industry exclusive, senses the power consumption of the pump and stops the pump at dry running. This system of level regulators is simple and reliable, when the liquid level rises to the Regulator, the position of the regulator changes. A switch will then start or Stop the pump. The regulator can also be wired to an alarm. The self-cleansing, maintenance free level regulator patented 0LC uses a micro switch to start and stop pumping whenever the liquid reaches the predetermined heights. The micro switch is protected with smooth polypropylene, resistant to most aggressive liquids. Rather than floating on the surface, the 0LC hangs immersed in the liquid, where is self-cleansing. This ensures that grease and solids that might otherwise stick to its surface do not affect operation. No toxic materials (such as lead or mercury) are used in its manufacture so it is suitable for use even under the most stringent conditions.

    Lift / Transportation

    FOR WASTE WATER CONTAINING LARGE SOLID PARTICLES :
    The pumps are equipped with a covered single and double side impeller running in a volute. The shape and the size of the side minimize clogging, and therefore make the pump ideal for wastewater containing large solid particles.

    The pumps are equipped with a covered single and double side impeller running in a volute. The shape and the size of the side minimize clogging, and therefore make the pump ideal for wastewater containing large solid particles.

    “Oz” is single side impeller with extremely good flow passing properties. This has been achieved by eliminating all parts in the impeller side where water flow at low speed might cause clogging.

    It is the unique design of “Oz”, combined with the design of the pump’s volute, which provide the clog free flow of sewage, Containing paper, textile and other critical materials. The “Oz” is designed for the smaller Z-pumps where the pump through let is small.

    The standard versions of these pumps are made of cast iron. As protection, all parts that come into contact with the pumped liquids are treated with a water-based basic coverage and a high-solid paint.

    Special finishes and zinc anodes for catholic protection can be supplied on request. For applications in explosive environments, most models can be supplied in explosion-proof versions. For corrosive applications, there are specific models in stainless steel. The maximum pumped-liquid temperature for the standard and explosion-proof versions is 40 degrees Celsius.

    All these pumps come equipped with stator winding over temperature monitoring. On request, oil-condition and stator housing leakage sensors can be built in. OK electrical industry can also provide a number of additional products aimed at ensuring trouble-free pumping; they include level regulators, alarm and monitoring systems, and lifting aids.
