Stud tensioning is typically accomplished at operating pressures beyond typical hydraulic pumps. We stock, sell and rent, and service pumps specifically designed for this purpose, up to 40,600psi (2800bar), as well as the required specialty hoses, fittings, and gauges for their safe use. Of course, equipment in these pressure ranges requires special training and experience to insure it is ready for safe operation, which we are proud to provide.
