Durable ointments transfer rotary lobe pumps

As high standard of pharmacy industry, surface roughness of pump wetted part can get 0.2um--0.8um. Pump also have certification of 3A, FDA, can be widely used for ointments, extractum, medicine latex, pill paste, medical syrup, vitamin, fermentation broth etc.

We are specialized in the production of rotor pumps and homogeneous pumps. The production capacity reaches 18,000 units/year. Our pumps can transfer medium with viscosity up to 1,000,000cps, with a maximum flow rate of 400m3/h (Capacity of 30L/r).
Our products manufacturing standard are divide to consumer chemical, refined chemical, food and beverage, paper making, chemical fiber, pharmaceuticals and coating. The core parts and sealing device of the products are made of different materials according to different properties of material, to meet variety medium and working procedures' requirement.

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. 

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.

We are a world-leading technology-based enterprise focus on R&D and manufactures non-Newtonian fluid conveying equipment. We specialize in rotary pumps, rubber rotary pump, roller pump, homogeneous pumps and grinding pumps. We have obtained 11 invention Patents and 46 practical patents, and won many national honorary titles, such as national champion of rotary pumps.

In the past 30 years, we dedicate to provide the scientific and professional solutions in fluid field. In the field of complex fluid transportation, our company's R & D technology, manufacturing technology, application technology is at the leading position in the world.

Durrex pumps can be widely used in food, consumer chemical, refined chemical, paper making, chemical fiber, pharmaceuticals, coating, etc. There are more than 100,000 units pump are running day and night, for more than 100,000 customers, which over 60 countries and area around the world. Such as Nestle, Mondelēz, MARS, P&G, Unilever, Colgate, Solvay, BASF, DUPONT, UPM, ECOLAB, GAW, LENZING, Sateri and so on.
