For high viscosity and solid-containing liquids! Claw rotary pump.

For high viscosity and solid-containing liquids! Claw rotary pump.

Outstanding performance for the transfer of all liquids! Completely sanitary high wear-resistant rotary pump.

The "Croid Rotary Pump" is a rotary pump designed to withstand the pumping of high-viscosity liquids containing solid materials. It has two lobes inside that rotate in sync via a timing gear, with no metal contact, resulting in minimal changes to the liquid quality. Additionally, it can be easily disassembled and assembled, making cleaning straightforward. 【Features】 ■ The bearing and timing gear section are completely separated and independent from the pump flow path. ■ High wear resistance. ■ Fully sanitary design that allows for easy disassembly, assembly, and cleaning. ■ Low-speed, fan-shaped rotors that do not destroy or alter the liquid quality. ■ The shaft seal uses a gland packing method (V-seal or mechanical seal methods are also possible depending on usage conditions). *For more details, please refer to the PDF document or feel free to contact us.

W-type cryo rotary pump

W-type cryo rotary pump

Sturdy and simple structure, standard type W shape.

Outstanding performance for transporting all types of liquids! This is a highly versatile rotary pump that can be used for high polymer polymers, chocolate, asphalt, and more. There is also a stainless steel SW type for the wetted parts. Inside the casing of the rotary pump, there are two fan-shaped blades that rotate in sync via a pinion gear, with no contact between the blades themselves. Additionally, there is no contact with the casing or cover. As the blades rotate, the chamber pressure on the suction side (the pressure in the space between the two blades and the casing) decreases, allowing liquid to enter. As the blades continue to rotate, the liquid moves along the inside of the casing toward the discharge side. Furthermore, the blades interlock, and the liquid is expelled from the pump.

[Basics and Trivia of Pumps] The Role of the Entire Pump

[Basics and Trivia of Pumps] The Role of the Entire Pump

What kind of machine is a pump? A detailed explanation! Introducing the overall role of pumps!

A pump is a machine invented with the idea of conveniently obtaining water, which is absolutely essential for human life, and has gradually evolved. It has developed to be commonly used for transporting liquids from low places to high places, or from a certain location to a desired location. In other words, it mechanically works on liquids to provide them with energy in the form of position, velocity, and pressure. Pumps can be classified into two types based on their principles and structures: "non-positive displacement pumps" and "positive displacement pumps." Our company manufactures positive displacement pumps, specifically "rotary pumps" and "gear pumps." 【Overview of Pumps】 ■ A machine for transporting liquids from a certain location to a desired location ■ Provides energy in the form of position, velocity, and pressure to liquids ■ Has two important capabilities: "suction capacity" and "discharge capacity" ■ Can be classified into non-positive displacement pumps and positive displacement pumps based on principles and structures *For more details, please refer to the PDF document or feel free to contact us.

[Example] Transport of doping solution in a chemical plant

[Example] Transport of doping solution in a chemical plant

Due to the mechanical seal, there is no need to re-tighten the shaft seal section! This is a case that has increased confidence against foreign matter contamination and dry running.

The pump that the customer was using had a shaft seal with a gland packing, which required regular tightening and could not operate dry, leading to certain issues. Therefore, we proposed the Nakakin Rotary Pump "JM Series." This product uses a mechanical seal, eliminating the need for tightening at the shaft seal, thus reducing labor costs and time spent on maintenance. 【Case Overview】 ■Issues - Cannot operate dry - Requires regular overhaul by swapping with a backup unit ■Proposed Product: Nakakin Rotary Pump "JM Series" - Capable of transporting low to high viscosity liquids - Low risk of foreign substances entering due to non-contact operation *For more details, please refer to the related link page or feel free to contact us.
