Agilent Technologies Mini Task AG81 Turbo Pumping System, ISO63, G8703A old part number 9699181
Overview:
The Agilent Mini-TASK AG81 pumping system consists of a pump with an integrated controller and a forepump.
Turbo Pump Description:
The turbopump consists of a high frequency motor driving a turbine fitted with 10 bladed stages and 3 Macrotorr stages. The turbine rotates in an anticlockwise direction when viewed from the high vacuum flange end.
The turbine is made of high-strength, light aluminium alloy, and is machined from a single block of aluminium. The turbine blades have five different angles, from 44° to 12°, while the Macrotorr stages are in the form of discs.
The turbine rotor is supported by permanently lubricated high precision ceramic ball bearings installed on the forevacuum side of the pump.
The static blades of the stator are fabricated in stainless steel. These are supported and accurately positioned by spacer rings.
The Macrotorr stators are in the form of selfpositioning machined discs with pumping channels and an opening restricted by the corresponding rotor discs. These are fabricated in aluminium alloy.
During normal operation, the motor functions with a power feed at 54 Vac three-phase at 1330 Hz. To reduce losses during start-up to a minimum, the frequency increases according to a ramp with a higher initial voltage/frequency ratio.
A thermistor sensor is mounted near the upper bearing to prevent the pump from overheating.
The pump is balanced after assembly with a residual vibration amplitude less than 0.01 µm.
Controller Description:
The integrated controller is a solid-state frequency converter which is driven by a single chip microcomputer and is composed of a PCB which includes a power supply with a 3-phase AC output, analog and input/output section, microprocessor and digital section. The controller recognizes the mains presence and converts the single phase AC mains supply into a 3-phase, medium frequency output which is required to power the pump.
The controller can be operated by a remote host computer via the serial connection.
Diaphragm Forepump Description:
The pump consists of an electric DC motor driving an eccentric which moves an elastic diaphragm.
The pump has four heads.
The compression chamber is hermetically separated from the drive mechanism by means of the diaphragm.
The pump transfers, evacuates and compresses completely oil-free.
The motor is supplied with a voltage of 24 Vdc.

We have invested in state-of-the-art equipment including; complete line of decontamination, cleaning, drying, balancing, vibration analysis and software to minimize failures. Our in-house machine shop is capable of machining various components, prototypes and housing conversions as needed.
We support all major manufacturers including Pfeiffer Vacuum, Alcatel / Adixen, Edwards Vacuum, Varian, Oerlikon / Leybod Vacuum, Vacuubrand, and Agilent Technologies.
Repair Steps
- Full incoming inspection and run up time check, vibration check, drive inspection.
- Full disassembly, decontamination and cleaning.
- Pump is balanced utilizing state-of-the-art equipment from the world leader in equipment balancing and analysis to reduce noise and vibrations and extend bearings life.
- Assembly and replacement of all necessary parts such as shafts, bushings, bearings, sleeves, O-rings, gaskets, seals, wicks, etc. Only parts that meet or surpass OEM specifications are used to ensure dependable highest quality service and long pump life.
- Final test and leak check. The pump in fully assembled condition is checked for vacuum seal. Leak test to 1 x 10-9 Mbar l/s. Vibrations are analyzed and test data is digitally recorded.
Every pump and instrument is extensively tested for 48 hours. During our final tests, we monitor total pressure, temperature, vibration and noise level utilizing newest testing technologies and techniques specified by OEM. Upon request, we can provide our customers with a pump down graph. Call us for your free repair estimate at 1-973-249-0854.
