    • Available Models

    Typical applications for chemical diaphragm pumps include the discharge of chemically aggressive gases and vapors from equipment such as rotary evaporators, vacuum dryers and concentrators. VACUUBRAND chemical diaphragm pumps have exceptional chemical resistance. Their fluoropolymer design makes them highly resistant to chemical vapors from inlet to outlet and very tolerant of condensates. Our two-, three- and four-stage pumps also have a gas ballast valve that ensures continuous purging with minimal impact on the highest vacuum when operating with condensing vapors. The pump chambers are hermetically sealed from the drive train, ensuring a long life for the mechanical parts. Most importantly, diaphragm pumps are oil-free, significantly reducing service requirements compared to oil pumps. They eliminate the cost of disposing of used oil as is the case with rotary vane pumps (oil pumps).

    VacuuBrand's chemically resistant diaphragm pumps are available for sale with different flow rates as well as with different final vacuum values. Single-stage models achieve vacuums of up to 70 mbar. Combining the pump heads in series as two-, three- or four-stage pumps allows the highest vacuum to be achieved down to 0.6 mbar. Parallel heads provide higher flow rates. The manufacturer offers combinations to meet virtually any laboratory need.

    The nomenclature for VACUUBRAND pumps is made up of the following codes that identify specific features or components:

    M = diaphragm pump

    E, Z, D, V = number of pump stages
    E = single-stage, up to 70 mbar
    Z = two-stage, up to 7 mbar
    D = three-stage, up to 1.5 mbar
    V = four-stage, up to 0.6 mbar

    C = chemically resistant

    NT = stands for the pump series that includes New Technology

    AK = separator tank for inlet or outlet condensates, collects particles and droplets, keeps condensate flowing in the vacuum line to the pump, protecting pump performance and providing additional noise reduction on the pressure side.

    EK = vapor condenser that guarantees 100% solvent recovery, compact design, protects the environment and air in the laboratory.

    TE = dry ice or water ice cooled condenser for solvent recovery

    PC = "Pumping unit, chemistry" - chemical pump with vacuum control and solvent recovery

    Chemical vacuum system = chemical pump with accessories such as inlet tank and/or solvent recovery

    Chemical pumping unit = chemical vacuum system with vacuum control and solvent recovery


    SYNCHRO = pumping unit for simultaneous operation of two independent vacuum applications with one pump

    VACUUBRAND offers chemically resistant vacuum systems, pumping units as complete systems to guarantee the desired vacuum range and flow rate. It is possible to maximize performance, its operation and environmental protection with the right combination of coordinated accessories. Basic pumps from different system families are mounted in a portable space-saving system and equipped with accessories suitable for specific applications.

    Components

    AK - separator for condensates on the inlet or outlet side. The inlet separator (on the suction side) collects particles and droplets of liquid. Vapor separator (pressure side) collects condensate at the outlet, prevents condensate from returning to the pump and helps keep the pump running quietly.

    EK - condenser for capturing vapors from the pump outlet. Made of shielded glass, it is compact but still very efficient. It allows virtually 100% solvent recovery and ensures protection of the laboratory atmosphere.

    EK Peltronic® - a cooler that requires no connection to water or dry ice. The cooling is based on Peltier technology.

    TE - condenser for dry ice or ice water for emission control and solvent recovery without cooling water supply.

    RK 500 or EK 1000 liquid level sensor: Prevents overfilling of tanks (on AK or EK); sends warning signals via an electronic vacuum regulator with VACUU - BUS® connections, and stops the pumping process if necessary.

    Gauge: Mechanical vacuum gauge provides trend indication and approximate vacuum levels on some of our more basic models.

    Two vacuum connections in one pumping unit: We have systems and pumping units with a second vacuum connection available for independent operation of two processes in parallel using only one pump. Check valves reliably isolate the two different applications from each other.

    M - Manual flow control adjustment: the flow control valve is designed to easily adjust the effective flow rate and is mounted on the inlet separator in some pumping units
