Questions & Answers

Have a Question?

Ask a Question

  • What is your pumps explosive-proof function? Is it suitable for explosive atmospheres?

    Dear Customer,

    The "R32 Explosion-Proof" refers to the pump’s ability to operate with air that has a flammability level not exceeding that of R32 refrigerant, rather than indicating suitability for use in explosive atmospheres.

    Thanks,

    Dear Customer,

    The pump is intended for operation in a room temperature environment.

Our previous vacuum pumps either did not have enough pressure or unstable control, which caused some experiments to fail. Since the introduction of this two-stage rotary vane vacuum pump, the problem has been solved.

Darian
New equipment

In the past, when doing freeze-drying experiments, the lack of vacuum always prolonged the experimental time, but this pump can quickly reach the ultimate vacuum, so that the experiment was shortened by almost half. Its automatic oil reflux prevention design also allows us to avoid a lot of unnecessary equipment cleaning work, it is really a customized equipment for the laboratory. We cannot live without it now.

G
Gabriel
Easy to operate

Vacuum pump is very well designed and easy to operate.

J
Jada
Vacuum Experiments

Daily work in our lab includes a lot of vacuum experiments, and the previous vacuum pump was either slow or not stable enough, often affecting the progress of the experiments. Then we changed to this two-stage rotary vane vacuum pump, and its efficiency and convenience made the experiments go more smoothly.

S
Serena
Fast vacuuming, high efficiency

Vacuuming speed is very fast and can reach the required vacuum degree in a short time, which greatly improves the working efficiency.
