Advantages
1. No lubricating oil in the pump chamber to get high purity vacuum.
2. Rotors processing with imported advanced equipment have the characteristic of good geometric symmetry, low noise and long service life.
3. The whole pump is made of aluminum alloy for corrosion resistance and lose heat quickly, so as to prolong the life of the pump.
4.  Quick start, to reach a vacuum in a short time.
5. Compact-sized, light weight and small footprint.

Application 
Roots Vacuum Pump are widely used in lighting, solar energy, electronics, semiconductors, vacuum drying, leak detection equipment, vacuum casting, vacuum ,elting, vacuum degassing, vacuum coating industry and vacuum distillation of the chemical pharmaceutical industry, etc.

Rto. 300 Roots Pumps for Vacuum Coating Machine
 

Plastic & Rubber Processing Machinery refers to general machinery, which manufacture and processing of rubber and plastic products.

The manchinery is used for EVA, PVC PE fpaming sole, rubber sole, TPR sole, rubber robber, rubber sponge, tyre, ball, rubber ring, rubber pipe, rubber belt, bottl stopper,oil seal, shock-resistant rubber, viscous adhesive tape, elastic tape, masterbatch, ink, electric rubber part, auto rubber product and chemical industrial blending materials.

18 inch refining mill

Advantage

1. The roller is made of chilled casting vanadium & titanium alloy iron which is hard    and wear-resisting, the surface hardness is above 70degree, the surface coating is about 15mm.

2. Hard tooth gear reducer with well-design structure, low noise, high efficiency and long    service life.

3. Self-aligning bearing is well matching with the bearing inside leakage-proof device.  The sealers are made of high temperature,wear, oil resistance material,which have very good sealing effect.

4. All main electrics are imported, the alternating current contactor is Shilin brand. The switch and button are Taiwan Tend brand.

5. Circulating lubrication system solves the oil leakage problem. The feature of this system is easy to maintain,easy to replace.

6. This machine is installed with overload protection device which protect the machine will not broken if the machine is overload.

The machine will reverse 1/3 round when press the emergency stop button,which sure the production safety.

7. The [U" shape frame is whole set casting, but other factory welded together.

8. The machine base is welded by national standard I steel.
