What type of mechanical seals are used?

The standard seals are John Crane mechanical seals, with optional materials including FPM or PTFE.

What is the motor protection grade?

The motor protection class is typically IP54 or IP55, with normal being IP44.

Can this pump replace reciprocating vacuum pumps?

Yes, oil ring vacuum pumps can completely replace reciprocated vacuum pumps due to their ability to reach lower suction pressures.

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 suction pressure achievable?

The suction pressure can reach 33mbar (abs) when using water as the operating liquid, or 6.7mbar (abs) when using transformer oil.

Q:How does the pump handle cavitation?

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

Q:Are stainless steel materials available?

Yes, parts where liquid flows such as pump casing, cover, port plate, and impeller can be made of SUS304, SUS316, or SUS316L stainless steel for corrosive conditions.

Q:What is the warranty period for this pump?

The warranty period is 1 year.

Q:Is the pump suitable for explosive environments?

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