    Vacuubrand MD 1C Vario SP Diaphragm Vacuum Pump Rebuilt, Refurbished

    Vacuubrand Diaphragm Pumps Overview

    VACUUBRAND's aluminum design diaphragm pump is a perfect match for many applications in the laboratory and operations because it is oil-free and whisper quiet, and because it requires so little service. Diaphragms have especially long lives and hermetically seal the drive space from the pumping chamber to protect mechanical parts from corrosion. The pumps achieve their distinctively high performance from high pumping chamber volume relative to the minimal dead space. Highly flexible FKM double diaphragms with fabric reinforcement ensure an extremely long diaphragm lifetime. The pumps operate absolutely oil free and do not have any sliding components in the gas path. In normal operation they are completely free of abrasion. Besides contributing to the long service intervals the lack of abrasion also eliminates most of the particulate impurities frequently generated inside of scroll or piston pumps. This makes VACUUBRAND diaphragm pumps the right choice for clean applications.

    • new internal connection technology for a very low leakage rate and reliable performance. Stable ultimate vacuum, even after a very long operating time
    • no abrasion - therefore dust and contamination-free
    • long diaphragm life due to highly flexible FKM double diaphragms, fabric-reinforced
    • FKM valves with excellent durability and vacuum performance
    • with innovative, patented drive system for quiet and vibration-free running

    The VACUUBRAND diaphragm pump line includes pumps with a wide range of flow rate and ultimate vacuum. Singlestage diaphragm pumps reach as much as 70 mbar (absolute) vacuum. By connecting pump heads in series of two, three or four stages, we can create pumps with ultimate vacuum reaching 0.3 mbar on some models. Connecting the heads in parallel produces higher flow rates. VACUUBRAND pumps combine these options to create pumps with the capabilities you need for most applications.

    Nomenclature for VACUUBRAND pumps is built from the following codes designating specific features or components:

    M = diaphragm (membrane) pump

    E, Z, D, V = number of pump stages from single (E) to four (V) stage design

    NT = labels the new series of pumps comprising the New Technology

    VARIO® = speed controlled pump with vacuum controller CVC 3000

    Many vacuum applications in laboratories and industrial operations require electronic vacuum control. VACUUBRAND's unique VARIO® control system offers the distinctive advantages and convenience of the CVC 3000 vacuum controller

    • precise vacuum control by continuously adjusting the motor speed of the diaphragm pump from 0-100%
    • when used as a backing pump for turbomolecular drag pumps (with backing pressure in the mbar range): Patented turbo mode with automatic speed adjustment for even better forevacuum
    • this results in lower heating and better residual gas performance of the turbo pump
    • unrivaled long diaphragm and valve lifetime by reducing the number of diaphragm strokes
    • very quiet, extremely low-vibration operation and significantly reduced energy consumption

    Vacuubrand Diaphragm Pumps with 24V DC drive particularly for integration into OEM products

    VARIO-SP™; diaphragm pumps from VACUUBRAND combine our proven diaphragm and cylinder head technology with state-of-the-art drive and control technology. This system component (SP = SystemPump) is frequently used in equipment or systems where it is beneficial and necessary to regulate vacuum parameters. The electronically commutated (brushless) 24 V direct current drive is service-free and features unparalleled compact dimensions. The high-quality and flexible electronic drive system built into the pump makes it easy to integrate the vacuum pump into your overall system. Varying the motor speed makes maximum efficiency possible, including the option of controlling vacuum processes by changing the pump's volume flow rate. Motor speed control also enhances performance features such as pumping speed, ultimate vacuum, diaphragm and valve live, vibration and sound levels and energy consumption. The motor speed may be set internally (fixed speed) or controlled via an external digital or analog signal.

    • possible variable speed 200-2400 min-1, allowing a quicker pumping down with high speed
    • improved ultimate vacuum at low speed
    • significantly longer diaphragm and valve service life
    • extremely compact, flexible mounting positions feasible
    • much quieter and less vibration
    • less energy consumption, less heat dissipation
    • speed can be set manually or controlled externally by various analog and digital signals
    • supply with 24 V DC for worldwide use

    Vacuubrand MD 1C VARIO®-SP Diaphragm Pump

    The three-stage MD 1 VARIO-SP diaphragm pump with its variable speed drive system attains significantly higher pumping speed and a better ultimate vacuum than the corresponding fixed speed pump. The brushless 24V DC motor (maintenance-free) enables easy integration of the pump into other equipment and operation independent of line voltage. The pump is particularly silent and vibration-free, and has an outstanding lifetime of its diaphragms and valves. For exceptional chemical resistance of the pump's internal flowpath it is also available as a chemistry design version (MD 1C VARIO-SP).

    Performance Features

    • contamination-free pumping and evacuation
    • high flow rate even near ultimate vacuum
    • variable speed: Fast pump down at high motor speed, maintain vacuum with reduced motor speed
    • very powerful and extremely compact; whisper quiet and ultra-low vibration, especially at low speed
    • MD 1C VARIO-SP in chemistry design, with gas ballast valve and outstanding chemical resistance and superior vapor tolerance


    The MD 1 VARIO-SP is an excellent choice for continuous, contamination-free evacuation and pumping of non-aggressive gases. The motor speed is either fixed or can be adjusted externally via electronic control signals for adaption to process requirements. For chemistry applications all major parts of the chemistry design pump MD 1C VARIO-SP in contact with pumped media are made of chemically resistant fluoroplastics. Both pump types are extremely compact and mountable in any position and are therefore the ideal built-in or system pump. Customized versions of these pump types are available on request.
