The new ZUTP-S Series is an extension to our existing line of ZUTP electric tensioning pumps. The ZUTP-S Series features a pendant-operated solenoid valve which is ideal for multiple bolt tensioning applications and allows for single-person operation. The operator can pressurize and retract the tensioner directly from the pendant. The pump achieves high-pressure without the need for an intensifier. This allows for low-maintenance and less cost for the user.
