ROCKER Rocker810 Oil-Free Vacuum Pump

Overview

The ROCKER Rocker810 Oil-Free Vacuum Pump is an engineered solution for laboratories requiring clean, reliable, and maintenance-free vacuum generation. Based on a precision-machined reciprocating piston mechanism, this pump operates without lubricating oil—eliminating oil carryover, vapor contamination, and scheduled oil changes. Its dry-running architecture ensures consistent performance across applications sensitive to hydrocarbon or particulate contamination, including analytical sample preparation, microbiological filtration, and environmental testing workflows. Designed and manufactured in Taiwan under strict quality control protocols, the Rocker810 delivers stable ultimate vacuum down to 50 mbar (equivalent to −735 mmHg) with a nominal pumping speed of 50 L/min at atmospheric inlet conditions. The integrated thermal overload protection system monitors internal motor temperature in real time, automatically interrupting operation during sustained high-load or ambient overheating scenarios and resuming function once safe thermal equilibrium is restored—enhancing equipment longevity and operational safety.

Key Features

• Oil-free piston technology ensures zero oil mist emission and eliminates cross-contamination risks in vacuum lines and downstream apparatus.
• Robust cast-aluminum housing and precision-ground stainless-steel piston assembly provide long-term mechanical stability and corrosion resistance.
• Thermal cut-off switch embedded within the motor winding prevents irreversible insulation degradation under abnormal operating conditions.
• CE-marked per Directive 2014/35/EU (Low Voltage Directive) and 2014/30/EU (EMC Directive), confirming compliance with essential health and safety requirements for laboratory use in the European Economic Area.
• Quiet operation at 68 dB(A) enables integration into shared lab environments without acoustic interference to adjacent instrumentation or personnel.
• Standardized 10 mm (3/8″) barbed inlet port supports universal compatibility with common vacuum tubing materials (e.g., silicone, PVC, and reinforced nitrile).

Sample Compatibility & Compliance

The Rocker810 is suitable for non-corrosive, non-condensable gas streams typical of aqueous filtration, air sampling, and vacuum drying procedures. It is not rated for solvent vapors, acidic gases, or abrasive particulates unless paired with appropriate external traps or scrubbers. While the pump itself does not require calibration per ISO/IEC 17025, its performance parameters (ultimate vacuum, flow rate) are traceable to factory verification under controlled ambient conditions (23 ± 2°C, 50% RH). For GLP- and GMP-regulated environments, users may document operational logs—including runtime, observed vacuum level via external gauge, and thermal event history—for audit readiness. The absence of oil-based lubricants simplifies validation documentation by removing the need for oil change records or residual oil analysis.

Software & Data Management

The Rocker810 is a standalone analog vacuum source with no embedded microcontroller, digital interface, or data logging capability. It operates exclusively via manual on/off switching and relies on external vacuum gauges (e.g., Pirani or capacitance manometers) for pressure monitoring. This design prioritizes electromagnetic compatibility (EMC), mechanical simplicity, and regulatory transparency—making it compatible with Class I, Division 1 laboratory electrical infrastructure and minimizing failure modes associated with firmware or communication protocols. Users integrating the pump into automated systems may employ external programmable logic controllers (PLCs) or relay modules to coordinate start/stop sequences based on vacuum setpoints measured by third-party sensors.

Applications

• Vacuum-assisted filtration of water samples for suspended solids (TSS) analysis per APHA Standard Methods 2540D.
• Microbiological membrane filtration for coliform enumeration (e.g., EPA Method 1603) and sterility testing in pharmaceutical QC labs.
• Deaeration of resin mixtures and composite precursors prior to casting or molding.
• Supporting vacuum ovens in material science labs for moisture removal from hygroscopic polymers and ceramics.
• Air sampling using impingers or filter cassettes compliant with NIOSH and OSHA sampling protocols.
• Evaporative concentration of low-boiling-point solvents in preparative chemistry workflows where oil contamination must be avoided.

FAQ

Is the Rocker810 suitable for continuous-duty operation?
Yes—when operated within ambient temperatures ≤35°C and with adequate ventilation, the Rocker810 supports uninterrupted operation up to 8 hours per day. Duty cycle limitations apply above 35°C or under sustained vacuum loads below 100 mbar.
Does it include a vacuum regulator or adjustable pressure control?
No—the Rocker810 lacks an integrated vacuum regulation valve. Pressure modulation requires external needle valves or electronic vacuum controllers installed downstream.
What maintenance is required over its service life?
Only periodic inspection of inlet filters (if externally added), hose integrity, and mounting stability. The piston seals and motor bearings are sealed-for-life components covered under the 2-year parts warranty.
Can it be used with aggressive solvents like acetone or chloroform?
Not directly—these vapors degrade standard elastomers and may condense inside the pump chamber. Use with a cold trap or chemical scrubber is mandatory for such applications.
Is there a version certified for use in explosion-hazard areas?
No—this model is not ATEX or IECEx certified. It is intended for general laboratory use in non-classified locations only.
