Product Description

Modern Design Abrasion Resistant Rotary Lobe Pump With Sanitary Grade
 

Product Description

Lobe pump with adjustable type is one of the products specially developed by Durrex pumps company to meet the customers the pipe height has changed condition. The base plate can be adjusted according to the working condition requirements. In order to facilitate the connection with the pipeline. Suitable for higher pipeline in working site.

Product features:

1. Gap is kept between the rotors and rotors & pump body, no friction, long using-life.  
2. Simple assembling and disassembling, easy to maintenance and clean, less easily-damaged parts.  
3. High efficiency and energy-saving, low failure, reliable sealing and low noise.   
4. In the same type pump, different type rotor can be interchanged. 
5. Capable to pmp the viscous medium from 1cp to 2million cps.  
6. Capable of pumping mixture of gas, fluid and solid medium.  
7. Equipped with inverter, the flow can be adjusted as requirement of end-user.   
8. Flange, screw or clamp connection can be selected as required.  
9. Higher hygienic grade, support CIP, SIP. The surface roughness is 0.2--0.8um, got 3A, FDA certification.  
10. Hygienic safety valve is built-in structure.

WORKING PRINCIPLE OF LOBE PUMP

Twin-Rotary pumps are multi-functional and bi-directional positive displacement pumps, produced with fine technology. The manufacturing engineering and precision of the pumps approach the advanced level of the world. Rotary pumps use synchronic rotors, driven by a pair of synchronic gears in the gear box. Transmitted by the main shaft and the sub-shaft. The rotors move synchronically in counter-clockwise directions, which, consequently, varies the pump capacity and builds up high vacuum capacity and emission pressure. It is particularly suitable to pump sanitary medium, high-corrosive and high-viscous medium.
