Sourcing & Buy FAQs

Everything you need to know about specs, custom options, and lead times.

Q1: What is your delivery time?

For small parts and small orders, delivery usually takes from a few days to around ten days, and sometimes one to two months or even half a year. For large project orders, it generally takes several months to half a year.

Q2: What is the lowest suction pressure (ultimate vacuum)?

Single-stage pumps reach about 33 mbar(A), the two-stage CBE2 series reaches 25 mbar(A), and the 2BW9 compound unit can achieve an ultimate vacuum of 0.5 kPa(A).

Q3: Can it handle corrosive, flammable or toxic gases?

Yes. Wetted parts can be made of SS304/304L/316L, duplex stainless steel, titanium alloy or Hastelloy, and ATEX-certified versions are available for explosive atmospheres.

Q4: What working liquid is used?

Water is standard. Closed circulation with a heat exchanger is available to reduce water consumption and operating cost.

Q5: What are the typical applications?

Oil refining vacuum distillation, flare gas recovery, adipic acid off-gas, chemical and pharmaceutical processes, power plant condenser exhauster and special gas transfer.

Q6: How do I select the right model?

Please provide suction pressure, capacity, gas composition, temperature and site conditions; our engineers will recommend the optimal model and package.
