Industrial compressors compress gas (most commonly air) to higher pressure for power tools, pneumatic actuation, process control, and industrial processes: rotary screw compressors — twin-screw positive-displacement design providing continuous, pulsation-free compressed air; available from 2.2 kW to 1,000+ kW; most common format for industrial compressed air generation; oil-injected (standard) or oil-free (required for food, pharma, and electronics); VSD (Variable Speed Drive) control reduces energy consumption in variable demand applications by 30–50%; reciprocating piston compressors — single or multi-stage piston design; suitable for lower continuous flow but very high pressure applications (up to 300+ bar for PET bottle blowing or diving cylinder filling); centrifugal (turbine) compressors — very large flow rates for process gas and air separation applications; scroll compressors — quiet, oil-free, suitable for medical and laboratory clean air; and vacuum pumps — dry screw, liquid ring, or rotary vane designs for industrial vacuum applications. Industrial pumps transfer liquid through piping systems: centrifugal pumps — kinetic energy design; most common for water, wastewater, and general liquid transfer; horizontal and vertical configurations; positive displacement pumps — gear, screw, lobe, or progressive cavity designs for viscous liquids, slurries, and metering applications; diaphragm pumps (AODD — Air Operated Double Diaphragm) — versatile, handles solids-laden liquids, self-priming, explosion-proof capable, no mechanical seal; widely used in chemical and mining applications; peristaltic (hose) pumps — minimal contact with pumped liquid, ideal for abrasive or hygienic applications; and cryogenic pumps — for liquid nitrogen, oxygen, LNG, and other cryogenic fluid transfer. Key certifications: ATEX (for explosive atmospheres), CE (machinery and pressure equipment), ASME (pressure vessels, USA), and IE3/IE4 motor efficiency ratings for energy-efficient designs.
Frequently asked questions
What is ATEX certification and when is it required for compressors and pumps?
ATEX (from French "ATmosphères EXplosibles") refers to EU Directive 2014/34/EU covering equipment intended for use in potentially explosive atmospheres — environments where flammable gases, vapours, mists, or dusts may be present. Examples: oil and gas facilities, chemical plants, paint booths, grain handling, flour mills, wastewater treatment (H2S), and battery charging areas (hydrogen). ATEX certification requires: equipment category (1G/2G/3G for gas zones, 1D/2D/3D for dust zones) matching the hazardous zone classification (Zone 0/1/2 for gas, Zone 20/21/22 for dust); certification by an EU Notified Body for Category 1 and 2 equipment; ATEX marking including Ex marking, equipment group, category, gas/dust classification, temperature class (T1–T6), and Notified Body number. For compressors and pumps in ATEX areas: motor ATEX certification (Ex eb, Ex ec, Ex nA motor winding protection); shaft seals compatible with ATEX requirements; and ATEX-rated control panels. IECEx is the international equivalent standard for global markets outside the EU.
What is a typical MOQ and price range for wholesale industrial compressors from China?
Chinese rotary screw compressors are available from many manufacturers including Kaishan (Shengzhou), Denair, Sollant, and FS-Curtis China: 7.5 kW oil-injected screw compressor (8 bar): USD 1,500–3,000. 22 kW oil-injected screw compressor (8 bar): USD 4,000–8,000. 75 kW VSD oil-injected screw compressor: USD 12,000–22,000. 75 kW oil-free screw compressor (Class 0): USD 30,000–60,000. Comparable Atlas Copco or Kaeser compressors are typically 2–4× these prices. MOQ: 1 unit (capital equipment). Lead times: ex-stock for standard models, 30–60 days for configured models. For centrifugal pumps from Chinese manufacturers (Grundfos China, KSB China, or domestic brands like CNP, LEO): 10–20% of equivalent European brand pricing for general water/HVAC applications.
