What are the motor specifications?

Motors are Y2 series with protection class IP54 or IP55 (normal is IP44) and insulation grade F.

Is the pump oil-free?

The standard 2BV series is an oil-free water ring vacuum pump. It can be converted to an oil ring vacuum pump by using transformer oil as the operating liquid.

What is the lead time for orders?

Peak season lead time is one month, while off-season lead time is within 15 workdays.

AI-Powered supplier vetting

SummaryThe supplier is a professional technical manufacturer and exporter involved in mechanical parts, general and special equipment, electrical instruments, auto parts, mining machinery, CNC equipment, and related products. It reports R&D capability, SDK availability, 3D design services, ODM services, OEM experience for well-known brands, and broad customization options. Production information lists annual outputs of 100,000 ring blowers, 5,000 roots blowers, and 3,000 water ring vacuum pumps, supported by 11–20 quality-control staff and three R&D engineers. Written procedures and records are reported for supplier assessment, corrective and preventive actions, and customer complaints. However, no new products were launched in the past year, raw-material traceability status is unknown, and no overseas warehouses, showrooms, agents, branches, or offline trade-show participation are reported. Certification holdings and specific customer cases are not provided.

Supplier typeThe supplier identifies as a professional technical supplier and operates across equipment manufacturing, mechanical parts, mining machinery, CNC equipment, electrical instruments, and auto parts. Its stated business scope also includes import and export of goods and technology, indicating both manufacturing and trading/export activity.

After-Sales capabilityThe supplier reports written procedures and followed records for corrective and preventive actions and for handling customer complaints, and emphasizes customer service and satisfaction. These records provide explicit evidence of service-management processes, although overseas service infrastructure is absent according to the provided data.

R&D capabilityThe supplier reports professional R&D capability, 3D software design services, SDK availability, ODM services, OEM services for well-known brands, and multiple customization modes. Nevertheless, it also states that no new products were launched during the past year, and its product-information R&D response is negative, so recent innovation output is limited.

Production capacityReported annual output includes 100,000 ring blowers, 5,000 roots blowers, and 3,000 water ring vacuum pumps. The supplier also reports 11–20 quality-control staff, exports to South America, Southeast Asia/Mideast, and Europe, and an off-peak lead time of one month, providing explicit evidence of established production and export operations.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, supported by professional R&D and 3D software design services. This indicates broad capability to adapt products to customer specifications.

Product Q&A

Q:What is the maximum vacuum degree achievable?

With water as the operating liquid, suction pressure reaches 33mbar (97% vacuum). With transformer oil, it reaches 6.7mbar (99% vacuum).

Q:Can this pump handle explosive gases?

Yes, the 2BV2-Ex and 2BV6 series are specifically designed for pumping explosive gases and working in flammable and explosive environments.

Q:What materials are used for the pump parts?

Parts where liquid flows can be made of various stainless steels (SUS304, SUS316, SUS316L) or aluminum bronze. The shaft is 2Cr13 or 0Cr18Ni12Mo2Ti.

Q:How does the pump prevent cavitation damage?

It features a cavitation protection port that opens or connects with a separator when working near limited vacuum to eliminate screaming and protect the pump.

Q:What is the maximum discharge pressure?

The maximum pressure is 0.26MPa (ABS). The motor must be selected based on the specific discharge pressure data.
