Import Air Cooled Dry Screw Vacuum Pump — Buy in wholesale FOB from Supplier in China

Taizhou Shouzhen Machineryco., Ltd offers dry compound screw vacuum pumps in three model sizes, SZS020, SZS050 and SZS080, with respective pumping capacities of 20, 50 and 80 cubic metres per hour. The ultimate pressure is rated at 3 Pa with a dry screw design that eliminates oil contamination, a critical requirement for sensitive industrial and laboratory environments. These units are air cooled, removing the need for water cooling infrastructure and simplifying installation in varied facility layouts.

The dry screw architecture uses precision-machined rotors with tight clearances to achieve vacuum without sealing oil, making the pump suitable for corrosive gas handling and applications where backstreaming would ruin processes. Materials of construction for the screw pair and chamber are typically hardened cast iron or stainless steel in standard industry practice, though buyers should confirm the exact rotor coating and casing material with Taizhou Shouzhen directly. The compound screw stage configuration allows these pumps to reach lower ultimate pressure than single-stage dry designs of equivalent throughput.

Primary applications span medical instruments, analytical equipment, pharmaceutical preparation and packaging, semiconductor fabrication, solar energy processing, and materials research laboratories. The absence of oil vapour makes the pump compatible with mass spectrometry, electron microscopy, and thin-film deposition systems. Buyers should confirm motor power, noise level, and port flange specifications with the supplier, as these are not stated in the listing. Standard operating ambient temperature range and recommended maintenance intervals are also points to clarify before purchase.

Taizhou Shouzhen Machineryco., Ltd is located at 118 Xinlu Road, Taiping Town, Wenling, Zhejiang Province, Taizhou, postal code 317500, China. The supplier holds a harbor trust tier, which indicates a baseline level of platform verification. The response rate is recorded at 0.00 percent with zero average response hours, meaning prospective buyers should expect delays or may need to follow up through alternative contact channels to receive quotations or technical clarifications.

The company profile visible in the listing does not disclose year of establishment, factory floor area, registered capital, employee count, or annual revenue. No certifications, patent holdings, or named client references appear in the source data. Buyers should request ISO 9001 or CE certification status directly, along with evidence of in-house rotor machining capability and quality control procedures such as helium leak testing or vibration analysis reports. The supplier's product range appears focused on vacuum equipment, though the listing does not confirm whether design or assembly is performed at the Wenling address.
