Jinteng GM-1.0A Dual-Mode Diaphragm Vacuum Pump

Overview

The Jinteng GM-1.0A Dual-Mode Diaphragm Vacuum Pump is an oil-free, maintenance-free laboratory pump engineered for precision control of both vacuum and positive pressure in analytical and preparative workflows. Based on proven diaphragm displacement technology, it operates via reciprocating elastomeric diaphragms driven by an eccentric cam mechanism—eliminating sliding friction, lubrication requirements, and hydrocarbon contamination. Unlike rotary vane or piston pumps, the GM-1.0A delivers clean, dry gas transfer with zero risk of oil backstreaming or particulate shedding—critical for applications involving sensitive detectors, sterile environments, or volatile organic compounds. Its dual-head architecture enables independent or synchronized operation of two isolated pumping chambers, supporting concurrent vacuum aspiration (e.g., filtration, degassing, solvent evaporation) and regulated positive-pressure delivery (e.g., sample purging, membrane pressurization, inert gas blanketing). Designed to ISO 8573-1 Class 0 air purity standards for oil-free operation, the GM-1.0A meets core functional requirements for GLP-compliant laboratories performing routine QC testing under ASTM D1796, USP , and ISO/IEC 17025 frameworks.

Key Features

• Oil-free diaphragm operation ensures contaminant-free vacuum and pressure generation—no lubricants, no exhaust oil mist, no scheduled oil changes.
• Dual-head configuration supports simultaneous vacuum (up to 200 mbar abs) and positive pressure (up to 0.08 MPa) output from a single compact unit.
• Aluminum alloy die-cast housing provides structural rigidity, thermal dissipation efficiency, and corrosion resistance in humid or chemically exposed lab environments.
• Passive cooling system with optimized airflow channels enables continuous 24/7 operation without thermal shutdown—even at ambient temperatures up to 40 °C.
• Adjustable pressure regulation via integrated needle-valve interface allows fine-tuned control over vacuum depth or pneumatic flow rate across defined operational ranges.
• Low-noise design (<55 dB[A] at 1 m) complies with ISO 3744 acoustic emission limits for shared laboratory spaces and quiet-zone installations.
• Modular inlet/outlet ports (Ø6 mm barbed fittings) support standard Tygon®, Viton®, or PTFE tubing; compatible with common vacuum manifolds, filter holders, and gas regulators.

Sample Compatibility & Compliance

The GM-1.0A is suitable for non-corrosive, non-condensable gases and vapors typical in pharmaceutical QC labs (e.g., nitrogen, argon, air, ethanol vapor below dew point). It is not rated for halogenated solvents, strong oxidizers (e.g., Cl₂, O₃), or acidic gases (e.g., HCl, SO₂) without optional chemical-resistant diaphragm kits. Built-in particulate filtration (pre-filter + activated carbon post-filter) ensures outlet air meets ISO 8573-1:2010 Class 2 particulate and Class 3 moisture specifications. The pump conforms to IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity) standards. Its electrical safety design complies with GB 4793.1–2007 (equivalent to IEC 61010-1), including reinforced insulation and double-pole switching. Documentation includes CE Declaration of Conformity, RoHS 2 compliance certificate, and factory calibration report traceable to NIM (National Institute of Metrology, China).

Software & Data Management

The GM-1.0A is a standalone analog device with no embedded firmware or digital interface. All operational parameters—including pressure setpoint, runtime, and duty cycle—are manually adjusted and monitored via external mechanical gauges or third-party sensors (e.g., capacitance manometers, mass flow controllers). For integration into automated systems, optional analog 0–5 V or 4–20 mA pressure feedback modules are available (sold separately). When deployed in regulated environments (e.g., FDA-regulated pharmaceutical labs), users may log operational data manually or via external DAQ systems compliant with 21 CFR Part 11 requirements—including electronic signatures, audit trails, and data integrity controls. Calibration records and preventive maintenance logs should be retained per internal SOPs aligned with ISO/IEC 17025 clause 6.4.10.

Applications

• Vacuum-assisted filtration (e.g., HPLC mobile phase degassing, microbial membrane filtration per ISO 7218).
• Rotary evaporation support for low-boiling solvents where oil contamination must be avoided.
• Gas chromatography carrier gas supply (with appropriate inline filters and regulators).
• Positive-pressure purging of GC autosampler vials, FTIR sample cells, or glovebox antechambers.
• Controlled atmosphere packaging validation in food safety labs (e.g., residual oxygen measurement per AOAC 990.11).
• Forensic evidence drying stations requiring particle-free airflow and stable sub-atmospheric conditions.
• Biochemical assay plate washing systems requiring programmable vacuum/pressure cycling.

FAQ

Is the GM-1.0A certified for use in GMP-regulated environments?

Yes—when operated within specified environmental and procedural limits, and supported by documented calibration, maintenance, and usage logs per internal quality system requirements.
Can this pump handle condensable vapors such as water or acetone?

It is not recommended for continuous exposure to condensables; optional cold trap or condensate separator accessories are advised for such applications.
What is the expected service life under continuous operation?

With proper ambient conditions (≤40 °C, low dust), the diaphragm assembly typically exceeds 10,000 hours of cumulative runtime before replacement.
Does the pump include vacuum and pressure gauges?

No—gauges are not supplied as standard; users must integrate external calibrated instrumentation per application accuracy requirements.
Is technical support available outside China?

Global distributor networks provide local installation guidance, spare parts fulfillment, and remote troubleshooting—contact regional Jinteng authorized partners for region-specific service coverage.
