Turbomolecular Vacuum Pumps

The National Institute of Standards and Technology (NIST) seeks a contractor to supply six high‑performance turbomolecular vacuum pumps (two each of 67 L/s, 260 L/s, and 685 L/s) to replace existing units in large‑geometry secondary ion mass spectrometers. The pumps must be fully interoperable with Ametek Cameca ims 1280/1300 systems, require no modifications to existing hardware, and include integrated RS‑485 controllers, power cables, air cooling, and operation manuals. Delivery is required within 20 weeks after award to NIST’s Gaithersburg, MD facility, with standard commercial warranty and acceptance testing by NIST staff. • Provide 2 × 67 L/s, 2 × 260 L/s, and 2 × 685 L/s turbomolecular pumps meeting specified flange, speed, and communication requirements. • Include electronic operations and maintenance manuals. • Ensure pumps are ready‑to‑install with no changes to existing vacuum housings. • Deliver within 20 weeks ARO to NIST shipping address in Gaithersburg, MD. • Warranty starts upon government acceptance; NIST will conduct inspection and testing within one week of delivery.
