WITH ITS SELF-PRIMING CAPABILITY, NAKAKIN MAINTAINS ITS LEADERSHIP IN THE INDUSTRY WITH JAPANESE TECHNOLOGY, STANDING OUT AS THE ONLY ONE IN ROTARY PISTON LOBE PUMPS!

What is the working principle of the Nakakin rotary piston lobe pump?

Nakakin Rotary Piston Lobe Pumps operate on the positive displacement principle. Two rotors on parallel axes are driven by a synchronized gear and rotate in opposite directions. They do not come into contact with each other or the pump housing. The seal of the pump chambers carrying the product is achieved by keeping the clearance between the housing and the rotor as small as possible. This design allows Nakakin Rotary Piston Pumps to create a vacuum and self-prime. The transfer occurs slowly, with low vibration, and is carried out delicately. Even particles can be transported without damage using a rotary piston pump.

What are the purposes of using Nakakin rotary piston lobe pumps?

Nakakin Rotary Piston Lobe Pumps, with their built-in safety mechanism, offer excellent suction and discharge capacity. Unlike contact-free pumps, they provide a constant flow. Their self-priming capability makes them unique among lobe pumps, and their superior suction feature allows them to function as vacuum pumps.

Nakakin Rotary Piston Lobe Pumps are certified with 3A and EHEDG, ensuring reliability through performance testing.

These pumps can transfer products with high viscosities of up to 300,000 cPs while maintaining the integrity of the material and ensuring a steady flow.

Thanks to their advanced technological design, Nakakin Rotary Piston Lobe Pumps can handle both high- and low-viscosity products with the same pump. Additionally, there is no need for a separate CIP pump.

What are the advantages of Nakakin rotary piston lobe pumps?

Nakakin Rotary Piston Lobe Pumps can self-prime from a negative suction head of up to 9 meters, allowing the transfer of high-viscosity products without requiring external pressurization. The pump’s rotor material, Nakamura Metal No. 3, is patented and resistant to thermal expansion, eliminating issues such as rotor-body friction and seizing. The patented rotor material provides a longer lifespan compared to rubber rotors. With Clean-In-Place (CIP) technology, the pump can be thoroughly cleaned without disassembly, saving time and eliminating the need for manual Cleaning-Out-of-Place (COP). All components in contact with the fluid can be easily removed, ensuring a longer lifespan for seals and simplifying maintenance. The pump’s patented seal, from the John Crane brand, features a sharpened movable surface and a reduced fixed surface area to minimize friction, ensuring a longer seal lifespan. Accessing the seal is simple—remove the pump cover and rotor, making disassembly and reassembly efficient. Since cleaning and maintenance do not require pump disassembly, operational downtime is minimized.

In Nakakin Rotary Piston Pumps, due to our stock-based working principle, spare parts are delivered from stock whenever you need them!

What are the material properties of Nakakin rotary piston lobe pumps?

The JM/JO model features an internal seal. The JM series uses a mechanical seal, while the JO series employs an O-ring seal. Its simple structure facilitates assembly and disassembly, ensuring long and efficient pump life at high performance. The SC series is designed for easy cleaning, with rounded edges and the elimination of pin carriers to prevent contamination buildup. Its simple structure also simplifies assembly and disassembly.

The JMU model features an external mechanical seal. Its straightforward design simplifies assembly and disassembly. Customers can choose between single, flushed, and tandem seals. This model is designed for the transfer of various fluids, particularly corrosive and fibrous ones.

The AMXN model is designed for the transmission of aseptic fluids and completely isolates the transferred fluids from the atmosphere to maintain sterile conditions. By distributing sterilized water and steam, these models are suitable for aseptic production lines requiring long-term preservation, such as dairy and pharmaceutical products.

Nakakin Rotary Piston Pumps use rotors made from “Nakamura Metal No. 3,” a patented material manufactured from stainless steel with reduced thermal expansion properties.

Additionally, Nakakin has set an industry milestone by reducing the clearance between the rotor and the housing to 70 microns. This minimal clearance enhances suction and discharge capacity, delivering consistent performance that outperforms competitors.

Nakakin Rotary Piston Pumps offer various mechanical seal options (internal, external, and flushed), providing customized solutions for every user and process. The internal mechanical seal design ensures easy assembly and disassembly.

Each series of Nakakin Rotary Piston Pumps supports particle tolerance, allowing fluid transfer without damaging the particles.

What are the capacity and other operating values of Nakakin rotary piston lobe pumps?

Nakakin Rotary Piston Lobe Pumps have a maximum capacity of 90 m³/h. The maximum discharge pressure is 15 bar, which can reach up to 30 bar in the high-pressure series. With a suction capability of 9 meters, they are unique worldwide. The maximum operating temperature is 150 °C, and the maximum viscosity is 300,000 cPs. Connection fittings are available in DIN11851, SMS, Clamp, and Aseptic Flange (custom options upon request). Nakakin Rotary Piston Lobe Pumps can operate in both directions.

They are available in horizontal and vertical mounting types. Mechanical seal options include materials like carbon ceramic, tungsten carbide, and silicon carbide, with additional material options available upon request.

What are the processes in which Nakakin rotary piston lobe pumps are used?

Nakakin Rotary Piston Lobe Pumps serve customers in the dairy, beverage, cosmetics, paint, chemical, and food industries. They provide wear-free usage for a minimum of three seasons in tomato paste transfer without the need for spare parts. They are ideal for transferring both viscous and non-viscous glucose without seal issues. They ensure smooth operation in processes such as the transfer of crystallized caramel and chocolate. For cream transfer, they offer precise transfer without altering the product’s structure. In ketchup and mayonnaise transfer, they deliver the desired capacity and pressure.
