Focus On High Quality Rotary Lobe Pump

We focus on R&D rotary lobe pumps for more than 30 years, we product high tech rotary lobe pumps are particularly suitable to pumped viscosity medium (viscosity up to 1,000,000cps). Our production capacity reaches 20,000units/year, maximum flow rate reaches 400m³/h (Capacity 30L/r). The manufacturing engineering and precision of the pumps approach the advanced level of the world.

These products 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 a 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.

These products consist of two series: hygienic rotary lobe pump, stainless steel rotary lobe pump. The products can be widely used in petrochemical industry, fine chemistry, consumer industry, pharmaceutical industry, foodstuff industry, environmental protection, paper-making, chemical fiber, painting, metallurgy, oil field and so on.

Advantages Of Rotary Lobe Pump

No Friction,Long Using-life

The Gap of high performance rotary lobe pump is kept between the rotors and rotors & pump body.

Simple Structure

Simple assembling and disassembling; easy to maintenance and clean; less easily-damaged parts and low maintenance cost.

High Efficiency And Energy-saving

High efficiency and energy-saving, low failure, reliable sealing and low noise.

Higher Hygienic Grade

Hygienic rotary lobe pumps support CIP, SIP. The surface roughness Ra 0.2-0.8μm, got 3A, FDA certification.

Customizable

Equipped with inverter, the flow can be adjusted as requirement of end-user.In the same type pump, different type rotor can be interchanged. Flange, screw or clamp connection can be selected as required.

Corrosion Resisting

Chemical-resistant rotary lobe pumps be applied to various complex working conditions, such as high temperature, high viscosity, high corrosion, etc.
