Electric Hydraulic Pumps

High Pressure Electric Pumps

Hydraulic tensioning is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical connections. At HTI, we’ve been building hydraulic tensioners, nuts, and pumps since 1986.

HTI’s Electric Operated Hydraulic Pump provides high-pressure hydraulic oil to pressurize hydraulic stud tensioners and hydraulic nuts. The electric-operated hydraulic pump comes standard with stainless steel glycerin-filled pressure gauges, comes fully calibrated, and includes a calibration certificate.

Featuring a large 4″ diameter hydraulic pressure gauge, HTI’s electric hydraulic pump is both easy to use and easy to read. This pump can achieve a pressure of anywhere from 0 – 30,000 psi, allowing you to easily pressurize HTI’s hydraulic tensioners and hydraulic nuts.

Not sure what type of pump you need?  Our engineers can help you determine the right pump for your tensioning application.
