Oil free pressure vacuum pump (positive pressure optional) is a kind of oil free lubrication compressor, compressed air purity, large displacement.

TOPTION KP-I handheld oil free diaphragm vacuum pump is widely equipped with experimental instruments,teaching equipment and scientific instruments, especially used with stainless steel multigang filters.

Your benefits of TOPTION handheld lab oil free diaphragm vacuum pump:

1.Pressure digital display, easy operation, stable performance, high precision measurement, quickly response speed.




2. Small volume, light weight, portable structure.




3. Oil-free piston pump, imported movement seals, low noise, long service life.




4. Continuous negative pressure regulation.




5. Electromagnetic motor, piston straight reciprocating movement produce compressed gas, large gas displacement.




6. Oil-free lubrication design, compressed air is more pure.




7. Cylinder and piston use SF-1 new wear-resisting material, long service life.




8. Pump shell is made of high quality ZL102 aluminum alloy material, cooperate with streamline design, heat dissipation effect is better.




9. Surface phosphating treatment, electrostatic spraying, colour and lustre is uniform, stronger adhesion.




10. Strong corrosion resistance, high-end laboratory pump.




11. Teflon material, can be used for pumping strong acid & alkali gas.




12. Single pump head, vacuum degree can reach 8 mbar, positive & negative pressure double use (positive pressure optional).




13. Support 24 hours long time running.

Note: Strickly forbidden charging oil and organic solvent.
