Description：
GMP-compliant sanitary centrifugal pump featuring a patented integrally forged impeller and shaft sleeve design that ensures perfect concentricity and vibration-free operation. The open-type impeller with deepened inlet cavity prevents cavitation while allowing easy CIP/SIP cleaning. Constructed with 316L/304 stainless steel (Ra≤0.4µm mirror finish), it includes dual mechanical seals for high-temperature applications (95°C+) and a drainage valve for zero liquid retention. Ideal for pharmaceutical, dairy, and beverage industries requiring aseptic processing.
Structure Characteristics and advantages of model series sanitary pump:
1. Open-Type Impeller Design
* Features a deepened inlet cavity to enhance pump intake performance and prevent cavitation
* Sanitary mirror-polished surface (Ra < 0.4 µm)
2. Taper-Fit Impeller & Shaft Assembly
* Impeller and shaft utilize a tapered matching design
* Sealed locking nut prevents liquid ingress into the shaft sleeve/threads, eliminating stagnant zones
3. Hygienic Mechanical Seal
* Bolt-free and spring-free construction ensures zero product contact areas
* Fully cleanable design without contamination risks
4. Self-Draining Pump Body
* Equipped with a drain valve to evacuate residual liquid, guaranteeing no dead legs
5. Material Specifications
* Wetted parts: 316L or 304 stainless steel
* Post-polish surface roughness: Ra < 0.4 µm
6. Sanitary Compliance
* All fluid-contact surfaces and connections are designed for CIP/SIP
* No residual retention after cleaning/sterilization, achieving true aseptic performance
