Structure Description
Pump Head: Made of 304/316L stainless steel with a mirror-polished finish, ensuring a hygienic and thorough pump body. The three-layer impeller design features a negative pressure self-priming structure and a quick-connect interface with top inlet and bottom outlet clamps for easy installation and maintenance. The pump body can also undergo CIP online cleaning and sterilization, meeting stringent hygiene standards.
Exhaust Negative Pressure Chamber: A dedicated negative pressure exhaust port is provided at the top, which can quickly create a vacuum and form a self-priming effect, eliminating the need for a bottom valve and simplifying the system design.
Motor Protection: Fully enclosed stainless steel square motor protective cover, waterproof and splashproof, suitable for cleanroom use, effectively prevents dust and rust, and extends motor life.
Base: The integrated stainless steel frame, combined with shock-absorbing rubber feet, ensures low noise and stability during pump operation, making it suitable for long-term continuous work.
Motor: Equipped with a standard three-phase stainless steel housing motor. Users can choose between frequency conversion or explosion-proof motor versions according to their needs. It is compatible with 380V industrial voltage to meet the needs of different working environments.
Product Advantages
Negative Pressure Strong Self-Aspiration: The unique negative pressure exhaust structure can completely suck up residual liquid at the bottom of the tank and low-level liquid, making it particularly suitable for return pumping in CIP cleaning systems and improving material utilization.
Complete Hygiene and Cleanliness Standards: The pump chamber undergoes mirror polishing, meeting the cleanliness standards of the food and pharmaceutical industries such as 3A and GMP, ensuring product safety and hygiene. The entire machine can be cleaned and sterilized online, reducing cleaning costs.
Full Stainless Steel Protection: The external stainless steel cover of the motor effectively isolates cleaning water and food residue, reduces dirt accumulation, facilitates cleaning and maintenance, and ensures that the equipment remains in good condition for a long time.
Simple disassembly and maintenance: The quick-release clamp design allows for tool-free disassembly and assembly of the pump head, and the replacement of seals and impellers is also very convenient, greatly reducing maintenance costs and time.
Low noise and stable operation: The combination of the shock-absorbing base and the stainless steel enclosed motor ensures that the pump will not overheat when working continuously for a long time in the workshop, maintaining a stable operating state.
Multi-functional and versatile: This pump can be used not only as a material conveying pump for production lines, but also as a return recovery pump when matched with a CIP cleaning system, achieving dual-purpose functionality and meeting various process requirements.
