    Edwards EH500 Mechanical Booster Blower Vacuum Pump

    Edwards EH Mechanical Booster Pumps

    The EH mechanical booster pumps feature the unique hydrokinetic drive, providing an efficient power transmission with benefits in economy, performance and compactness. The hydrokinetic drive provides the following features:

    • Pump down times cut by 50%, when compared with direct drive pumps
    • No bypass lines or pressure switches required
    • Universal voltage motors
    • Reduced capital and operating costs
    • Air cooled motors - with water cooled options
    • Quiet, minimum vibration

    The EH mechanical booster pumps, based on the simple Roots principle, remain the favorite pumps for applications where high pumping speeds over 3000 m3h-1 / 1776 ft3min-1 are required in the pressure region of 0.01 to 50 mbar / 0.0075 to 37.5 Torr. These pumps must always be backed by another pump which can deliver against a high pressure differential to atmospheric pressure.

    Operating at relatively low pressures, the mechanical booster pump is not exposed to the same concentrations of corrosive process media as is the backing pump, which makes it highly reliable.

    High Performance Pumping Mechanism

    The EH has a high quality, oil-free pumping mechanism. This offers:

    • Quiet, vibration free operation
    • Rugged and corrosion resistant
    • Advanced shaft-seal technology - no oil contamination of process chamber

    The corrosion resistant pumping mechanism is manufactured from high grade cast iron. The proven shaft-seal arrangement ensures that no oil enters the pumping stator, and the absence of internal and external by-pass lines and valves which may corrode or stick minimizes maintenance requirements.

    The design of the shaft seals is optimized to ensure that no lubricants can migrate into the pumping mechanism. This maintains booster pump performance in applications which demand the highest standard of cleanliness. In addition, this prevents the build-up of trapped particles on the rotor lobes and end-faces which have very close tolerances.

    The dynamically balanced rotors and precision ground gears contribute to the smooth, quiet operation of the pumps, as demanded by manufacturers of advanced technology equipment.

    Broad Application Coverage

    EH mechanical boosters are available to cover a broad range of industrial and chemical process applications.

    Industrial

    Industrial EH boosters are safe to handle non-flammable gases and vapors within the normal operating parameters of the booster.

    ATEX

    ATEX classified EH boosters are annotated with the suffix "T3" or "T160".

    • EH boosters may be supplied with ATEX classification either as part of a pump system or stand-alone, on application. Please consult Edwards.
    • ATEX compliance is typically specified for use in Europe, but may also be required in other areas.

    ATEX compliant EH boosters are suitable for operation in ATEX systems rated as follows:

    All of the EH1200C, EH1200 T160, EH2600C, EH2600 T3, EH2600 T160, EH4200C, EH4200 T3 and EH4200 T160 chemical EH pumps are fitted with flameproof motors:

    • Pumps suitable for 50 Hz operation are fitted with a flameproof motor approved to EEx d. Gas Group IIA, lIB, Temperature Class T4.
    • Pumps suitable for 60 Hz operation are fitted with a flameproof motor approved to CSA, Division 1 area, Gas Class I Group C & D, and Dust Class II Group F & G, Temperature Class T3C.

    Internal and External Classifications

    (Ex) II 2G c IIB T3 or

    (Ex) II 2G c IIB T160

    The notations used in these ratings are as follows:

    Symbol Meaning

    Equipment Category

    For equipment category 1 (gas) consult Edwards.

    Gas Auto-Ignition Temperature

    The temperature classifications applied to the chemical EH pumps relate to the auto-ignition temperature of flammable materials that can be pumped:

    • The EH1200C, EH2600C, EH4200C and chemical EH pumps that have a T3 classification are suitable for pumping flammable materials that have an auto-ignition temperature greater than 200 °C.
    • Chemical EH pumps that have a T160 classification are suitable for pumping flammable materials that have an auto-ignition temperature greater than 160 °C.

    Explosion Proof

    Explosion proof boosters are annotated with the suffix "C".

    • EH boosters may be ordered with explosion proof motors either individually, or as part of an explosion proof system.
    • Explosion proof is generally applicable in N. America and the rest of the world (excluding Europe).

    Explosion-proof boosters will be supplied fitted with an explosion-proof motor (suitable for 60 Hz operation) approved to CSA, Division 1 area, Gas Class I Group C & D and Dust Class II Group F & G, Temperature Class T3C.

    EH Pumps with Hydrokinetic Drive

    EH booster pumps have a unique and patented hydrokinetic fluid drive, which couples the motor to the pumping mechanism. The hydrokinetic drive offers the following advantages:

    • Pump down times cut by up to 50%
    • Reduced capital and operating costs
    • No pressure sensors, by-pass lines or valves
    • Can operate continuously at all pressures - when used with a backing pump

    EH booster pumps have universal voltage, air-cooled motors and are available with effective pumping speeds of up to 4140 m3h-1 / 2440 ft3min-1. The pump bodies of the EH1200, EH2600 and EH4200 pumps are water-cooled.

    Two versions of each EH booster pump are available, with different oils used for the lubrication of the seals and gears. The standard version uses mineral oils, such as Ultragrade 20. The alternative version has PFPE (perfluoropolyether) oils and is suitable for applications where oxygen or other reactive and corrosive gases are processed.

    Pump-Down Times cut by up to 50%: The hydrokinetic drive allows the booster pump to be started at the same time as the backing pump (at atmospheric pressure) as it prevents motor overload. The EH booster pump therefore assists the pumping process from the start of pump-down. In comparison pumping systems with conventional, direct drive mechanical booster pumps (where the booster pump is switched on when the chamber pressure has been reduced to, typically, less than 10 mbar / 7.5 Torr), the total evacuation time can be reduced by as much as 50%.

    Automatic Overload Protection: The hydrokinetic drive automatically varies the rotational speed of the pump. This protects the motor from overload, prevents over-heating, and allows the pump to operate with high pressure differentials. Consequently, EH booster pumps are not damaged by sudden increases of inlet pressure and even by the entry of solid debris into the pump.

    Important Cost Savings: When you use EH mechanical booster pumps, you save money on installation and operation. Your capital costs are reduced as you do not need valves, by-pass lines and pressure switches, and you can use a smaller backing pump than with conventional drive booster pumps. Operation costs are reduced because EH booster pumps have smaller motors than direct drive pumps and, when operating at full speed, they use only a fraction of the rated power.

    The EH mechanical booster pump, based on the simple Roots principle, remains the favorite pump for applications where high pumping speeds are required for pressures in the region of 0.01 to 10 mbar. This pump must always be backed by another pump, which can deliver against a high-pressure differential to atmospheric pressure.

    Operating at relatively low pressures, the mechanical booster pump is not exposed to the same concentrations of corrosive process media as is the backing pump, which makes it highly reliable.
