The TURBO 60G is a compact, air cooled, portable turbopump package. This fully integrated 35lb. package includes a 60 L/SEC hybrid turbomolecular pump, an oil-free backing pump, automatic valving, and a control module. Operation is automatic and interlocked, and the TURBO 60G is not adversely affected by operator error or power failure.

• Vacuum in the user's system remains undisturbed in power failure situations.
• Compact and portable. The footprint is 8" x 11", and the total weight is 35 lbs.
• Modular construction permits direct mounting of the turbopump to the system flange, and remote mounting of the control module.
• The rugged, industrial-grade,
• oil-free backing pump has a mean-time-between-failure rating of 25,000 hours for the rotating mechanisms.
• A wide selection of standard inlet flanges is available.

HIGHER NET PUMPING SPEED The hybrid turbopump can be directly mounted onto the user's system flange. This results in substantially increasing the net high vacuum pumping speed at the system inlet. The exhaust pressure of the hybrid pump is in the viscous flow range. This permits remote mounting of the backing pump without increasing pumpdown time. MODULAR DESIGN Standard plug-in extension cable sets, and extended foreline kits are available to configure the TURBO 60G package to suit each user's requirements. These items permit remote mounting of all of the following: turbomolecular pump, control module, and the diaphragm pump. If the user's needs change, the TURBO 60G can be easily reconfigured in the field. MAINTAINS VACUUM IN POWER-FAIL SITUATIONS The oil-free backing pump used in all Drivac packages eliminates the requirement of venting the turbopump in power-fail situations. When the power goes off, the normally-closed solenoid valve isolates the turbopump from the backing pump. When power resumes, a time-delay relay keeps this valve closed until vacuum is re-established in the foreline. DRIVAC VACUUM MONITOR The VACUUM MONITOR sensor and circuit incorporated into the TURBO 60G package automatically controls operation of the hybrid turbopump. VACUUM MONITOR prevents extended operation of the turbopump at high pressures. This helps to maintain a lower operating temperature of the turbopump thereby enhancing long term reliability. DUAL DIAPHRAGM PUMP The H-60 two-stage diaphragm pump has a MTBF rating of 25,000 hours for the rotating mechanisms. While a pressure of 10 Torr is sufficient to back the hybrid turbo pump, the H-60 has an ultimate vacuum capability of 4 Torr. This provides a wide margin for proper backing pressure, and also results in faster mid-range roughing compared to competitive pumps with 9 to 10 Torr capability. EXTREMELY COMPACT &COMPLETELY PORTABLE The footprint of the TURBO 60G is 8" by 11". The total weight is 35 lbs., and a carrying handle is included. All Drivac packages are air cooled, and they do not require liquid nitrogen, bake-out, or cooling water. The only utility required for the TURBO 60G pump package is 110V, 5 amps.
