High Precision Lobe pump with waterproof cover with 3A/ FDA for
High hygiene standard industryLobe pump with waterproof cover is
one of the products specially developed by Durrex pumps company.
The pump is equipped with a detachable protective cover for the
whole machine, and the material is S.S., it can protect the motor,
coupling and other parts from corrosion during on-site cleaning.
Mainly used for working conditions with health requirements, such
as food, medicine and other industries.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. Structure drawing and main

PUMPTwin-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. Technical
