Double Stage Rotary Vane Vacuum Pump

Introduction

A double stage rotary vane vacuum pump provides higher vacuum levels than single-stage systems. It is widely used in advanced laboratory applications requiring deep vacuum conditions. The system ensures stable performance for freeze drying and analytical instruments.

Standards

ISO 21360-1:2020-Vacuum technology-Standard methods for measuring vacuum-pump performance-Part 1: General description

GB/T 40344.1-2021-Vacuum technology-Standard methods for measuring vacuum-pump performance-Part 1: General description

Complies with the above standards, but is not limited to them.

Features

1. Quick-release fittings speed tubing changes.

2. Gauge and regulator allow clear control of output.

3. Gas-ballast or purge options help handle condensable vapours.

4. Oil-free or sealed designs reduce contamination and maintenance.

5. Chemical-resistant wetted parts handle a range of media.

FAQ

What is the Double Stage Rotary Vane Vacuum Pump mainly used for?

The Double Stage Rotary Vane Vacuum Pump is used to move, evacuate or transfer fluids and gases in laboratory and process work. It supports filtration, vacuum drying, aspiration, chromatography and sample handling.

Which standards and regulations apply to the Double Stage Rotary Vane Vacuum Pump?

The pump is designed with reference to IEC 61010 electrical safety and relevant GB/T standards for laboratory pumps. Vacuum and pressure ratings should match the application. Compliance documentation can be provided on request.

What warranty comes with the Double Stage Rotary Vane Vacuum Pump?

The system is covered for 12 months after shipment, including the main mechanism and electrical controls. Replaceable consumables and routine service items are not part of the warranty. Faults caused by improper installation outside the manual or unauthorised modification are not covered.

Will staff need special training?

Day-to-day use is simple, with clear prompts and pre-set functions reducing manual steps. New operators should review the manual and complete a short familiarisation. Our technical team offers remote support during the first runs.

What is the typical lead time for order delivery?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Does the Double Stage Rotary Vane Vacuum Pump need calibration or verification?

To protect result reliability, periodic verification should be performed, typically once or twice a year. The instrument arrives factory-calibrated, and self-check routines help spot drift. We offer traceable calibration service if the site needs it.

Are the consumables universal or proprietary?

Common consumables and standard spare parts are available through our service channel and are not locked to proprietary formats. Quote the model and serial number when ordering so the correct items are supplied. Lead time for standard parts is usually short.

Are options or configurations available?

A range of options is available to match the application, such as alternative settings, fittings, data outputs or power supply. We confirm each option and its effect on price and schedule up front. Larger custom builds can be discussed.

How is the Double Stage Rotary Vane Vacuum Pump commissioned?

Standard installation is straightforward and supported by the manual and start-up documentation. Our technical team can guide staff remotely through checks and validation. On-site commissioning is available as a quoted service.

What should be avoided when using the Double Stage Rotary Vane Vacuum Pump?

Do not pump incompatible, corrosive or particulate media without protection, run dry or block exhaust. Use traps and inlet filtration. Follow laboratory safety rules.
