Sanitary specification Invol (Inner Vortex) pump
A solid material transfer pump that can gently transport large solid objects without breaking them.
The Invol (Inner Vortex) pump is a pump that can transport liquids along with solids without breaking them. It is also ideal for transferring high-viscosity liquids and liquids containing bubbles! There is no risk of solids getting caught. It is a pump that transfers solids without breaking or damaging them. [Examples of Use] ◆ Transfer of relatively soft solids Nata de coco, quail eggs, cherry tomatoes, small plums, tea leaves ◆ Transfer of relatively hard solids Rice, soybeans, pickled garlic, garlic, potatoes, ginger, cucumbers ◆ Transfer of high-viscosity liquids Mayonnaise, ketchup, yogurt, butter ◆ Others Raw materials for construction putty, liquids containing catalysts

Characteristics of the Inner Volute Pump (Invol) for transporting solids and high-viscosity liquids in IVD There is no risk of solids getting jammed like in rotary pumps. "It can transport solids without breaking or damaging them" - that is the Inner Volute Pump from Nikuni.
-
■Transport of pickled cucumbers and radishes ■Transport of pickled cucumbers and radishes With conventional rotary pumps, there were frequent incidents of pump locks due to solid materials jamming the rotor and residual accidents where products could not enter the pump. The ultra-simple structure of the involute completely resolved these incidents with a smooth flow of liquid.
-
■Transport of pickled shallots ■Transport of pickled shallots In conventional centrifugal pumps and vortex pumps, the "intense flow" and "impact from the impeller" caused the skin to peel off and the product to break apart. The gentle flow of the involute, which does not make contact with the product, prevents damage and significantly improves quality.
-
■Reduction of labor costs and safe operations (Stew factory) The previously dangerous and strenuous high-altitude work of using a ladder to transfer materials to the cooking pot via a bucket relay has been automated with the introduction of Invol. This has achieved significant cost reductions along with the promotion of safe operations and improved work efficiency.

Nikuni Co., Ltd. is a company (manufacturer) engaged in the development, production, and sales of pumps. In particular, we focus on the development, production, and sales of products centered around vortex turbine pumps, as well as the development, production, and sales of devices that improve the environment within factories by incorporating pumps (such as coolant systems and filtration systems). Pumps are the heart of devices and equipment. As a precision machinery manufacturer, Nikuni has been producing high-precision, high-quality components for many years. Utilizing our machining technology, Nikuni produces pumps with precision that exceeds the norms of general pumps (such as perpendicularity, parallelism, concentricity, and runout), resulting in pumps that pursue high precision and high quality. To prevent issues, we conduct a full inspection of all pumps before shipment, ensuring that only those that meet Nikuni's quality standards are shipped. Nikuni manufactures and sells products so that everyone involved with pumps can use them with confidence.
