【Exhibiting at FOOMA JAPAN】For beverages and food! Simplifying daily decomposition/cleaning! Air-driven diaphragm pump.

The sanitary pump "One Nut Pump" handled by Chuo Rika is an air-driven diaphragm pump suitable for food, beverages, cosmetics, pharmaceuticals, and more. It reduces the time required for daily disassembly, cleaning, and reassembly! It is CIP-cleanable and can withstand high-temperature steam! It has a pressure resistance of up to 0.7 MPa! Each part has no dead angles, allowing for thorough cleaning without missing any residues or dirt. We have received feedback that the residual bacteria after cleaning is zero, and since there are no sliding parts made of metal, very little iron powder is generated. You can experience easy disassembly and reassembly at the Interphex exhibition! We also offer free demo units for loan, so please feel free to contact us. 【Product Features】 - Zero residual bacteria inside the pump after CIP cleaning - Easily disassembled with just one nut, providing excellent cleanability - Can be cleaned with hot water and steam - Suitable for transporting high-viscosity liquids such as creams and jams - Stainless steel is standard in SUS316L - Ideal as a replacement for rotary pumps and screw pumps (superior in cost and maintenance workload) - No sliding metal parts, so no iron powder is produced
