Overview:

BOC Edwards QMB Mechanical Booster Pumps are compact and have high pumping speeds. Low system pressures can be achieved by using two or more mechanical booster pumps in series.

You must use the QMB Mechanical Booster Pump with a suitable backing pump. The maximum continuous inlet pressure is 20 mbar for the QMB250F and QMB500F Mechanical Booster Pumps and 1 mbar for the QMB1200F Mechanical Booster Pumps.

The QMB250F and QMB500F pumps are air-cooled and the QMB1200F pump is water-cooled. All the QMB pumps have enclosed, water-cooled motors and are therefore suitable for applications in clean environments where fan cooling is unacceptable.

The pump coupling-cover is connected to the pump outlet and forms an integral part of the vacuum system. The connecting pipelines have a filter which removes debris and so prevents contamination of the lubricating oil and bearings. For an even cleaner system, the coupling-cover and bearings can be evacuated by connection to the pump-inlet or to an external vacuum pump.

Three motor-protection thermistors (one on each winding) are fitted to the motor of the QMB pump. These thermistors are solid-state devices which have an electrical resistance of 100 to 500 W at normal pump-motor operational temperature. When the pump-motor is too hot, the electrical resistance rises quickly to 3000 W. The thermistors are connected in series and you can connect the thermistors to control equipment to automatically shut down the system if a pump-motor is too hot.

Unit is fully rebuilt and comes with a FULL 12-MONTH WARRANTY!

General Overview:

The EH pumps are compact and have high pumping speeds. You must use the EH pump with a suitable backing pump. The EH pumps can operate with a maximum continuous inlet pressure of 1000 mbar. You can achieve low system pressures by the use of two or more EH pumps in series.

The EH pump coupling-cover is connected to the pump outlet and forms an integral part of the vacuum system. The connecting lines have a filter which removes debris and so prevents contamination of the lubricating oil and bearings. For an even cleaner system, you can evacuate the coupling-cover and bearings by connection to the pump-inlet or to an external vacuum pump.

The hydrocarbon safe area and chemical EHpumps use hydrocarbon oils, such as Ultragrade 20. Versions of the safe area pumps for use with PFPE (perfluoropolyether) oils are also available for vacuum systems in which oxygen or other reactive or corrosive gases are pumped All the EH pumps have ISO inlet-flange and outlet-flange connections.

Edwards_EH250_Vacuum_Booster_Tech_Data 

Overview:

The EH250 Vacuum Booster pumps are compact and have high pumping speeds. You must use the EH pump with a suitable backing pump. The EH250 Booster pumps can operate with a maximum continuous inlet pressure of 1000 mBar. You can achieve lower system pressures by the use of two or more EH250 pump in series.

On all EH250 pumps, the hydrokinetic drive/gearbox is connected to the pump outlet by a pressure equalisation passageway, and forms an integral part of the vacuum system. The connecting passageway has a filter which removes debris and so prevents contamination of the lubricating oil and bearings. For an even cleaner system, you can evacuate the end-cover/gear cover by connection of the evacuation port to the pump-inlet or to an external vacuum pump.

The hydrocarbon safe area, ATEX compliant and chemical EH 250 pumps use hydrocarbon oils, such as Edwards Ultragrade 20. Versions of the safe area EH 250 pumps for use with PFPE (perfluoropolyether) oils are also available for vacuum systems in which oxygen or other reactive or corrosive gases are pumped. The EH 250 pumps must not be used to pump peroxides.

The EH pumps are positive displacement Roots vacuum pumps. The pump mechanism is driven by a three-phase electric motor through a hydrokinetic drive.

The pump shafts and rotors are made of cast SG iron. The internal and external shaft-seals are made of polytetrafluoroethylene (PTFE) or fluoro-elastomer. The pump-bearings, gears and seals are lubricated by oil fed from reservoirs in the hydrokinetic drive/gearbox. A series of seals stops the oil from reaching the vacuum side of the EH-250 pump. The hydrokinetic drive/gearbox is evacuated. You can inspect the oil-levels through sight-glasses which are fitted to the hydrokinetic drive/gearbox. Oil-filler, oil-drainage and external evacuation connections are provided on the hydrokinetic drive/gearbox. A30152936,

We repair and service all Edwards Booster pump, such EH250, EH500, EH1200, EH2800, QMB250, QMB500, QMB1200, QMB2600 Boster pump repair.
