Dry Screw Vacuum Pump
Dry Screw Vacuum Pump
The range of dry screw pumps is ideal for your low and medium vacuum applications. It can not only be used for industrial applications, but also for coating. Our dry screw pumps are ideal solution for all areas requiring oil-free vacuum. Pumping speeds in this series range from 100 to 2,500 m3/h.
The one-piece variable-pitch rotors are a special advantage. We provide the necessary internal compression to save energy costs. The innovative design and low speed of the pumps result in low stressing of the bearings and seals.
Features :-
New Design
- The compact design that emphasized curved line of casing and plate(REP2) was removed.
- Improving the part connected with motor by IEC flange type.
Removed Air Filter
- The strong anti corrosion by blocking the inflow of air into pump/it is safe in even explosive circumstances.
- Minimized contamination in application circumstance due to no process material back-flowed.
Mechanical Seal
- Protection from water or oil contamination by using the seal which has outstanding sealing effect.
- Enlarged sealing effect as compared to lip seal of other companies.
Simple internal structure
- Increasing life time of pump by non contacting between casing and screw.
- Easy overhaul/maintenance and minimized minor faults by simplifying the internal structure.
Line-UP
- Consisted of various lines from low to high capacity.
Dry variable pitch screw
- Eco-friendly pump which is no need oil or water that is to form oil film inside pump also no additional cost come from waste water.
- Keeping constant vacuum degree even for long time operation without influence of internal/external circumstances.
- Reducing utility cost as applying variable pitch screw that helps reduce power consumption and discharge temperature. Coating
Coating
- Applying special TEFLON coating which is the most superior for the corrosion.
- Easy to treat toxic, corrosive gas and condensable gases.
The Range of using pressure of pump
- It is possible of continuous operation in the all pressure range by forming vacuum with mechanical rotation of screw.
- No change of using power in accordance with vacuum degree (low to high).
IEC Flange
- Increasing customer convenience by applying IEC flange.
- Simple installation due to no need to adjust shaft alignment when pump is to moved.
