Enerpac ZUTP1500 Electric Tensioner Pump with Remote Controlled Valve Provides Simple, Fast Bolt Tensioning for Wind Turbine Market


Menomonee Falls, WI (PRWEB) March 07, 2012

Enerpac introduces the ZUTP1500 Electric Tensioner Pump with Remote Controlled Valve, the latest addition to the companys robust line of ZUTP-Series Electric Tensioning Pumps. This series features a two-stage pump design to provide high flow at low pressure for fast system fills, as well as controlled flow at high pressure for safe and accurate operation.

Designed for the demanding needs of the wind turbine market, the new ZUTP1500 is the only electric tensioner pump on the market to feature a remote-controlled electric valve and universal motor without a hydraulic intensifier. The resulting pump facilitates hassle-free operation of bolt tensioners and hydraulic nuts in remote locations. With a low-pressure flow rate of 230 in3 per minute and a full-pressure flow rate of 20 in3 per minute, the new three-piston, two-stage pump design powers bolt tensioners up to two times faster than competitive pumps.

Since the ZUTP1500 is able to generate 1500 bar (21,750 psi) of pressure without the use of an intensifier, it is less sensitive to contamination in the hydraulic fluid, more reliable and offers a lower operating cost than similar competitive units. Plus, the design is rugged, lightweight and compact, providing an ideal fit for tight openings common in space-restricted wind turbine applications.

Also delivering an ideal solution for bolt tensioner and hydraulic nut applications in the mining and power generation industries, the feature-rich pump is prepared for immediate use and built for fieldwork. The ZUTP1500 includes a durable, lightweight aluminum roll cage and reservoir with a sheet metal front panel to guard the pump from the rigors of the worksite. With a high-efficiency pump design and heavy-duty universal motor, the ZUTP1500 has a cooler operating temperature and draws less current than similar competitive pumps, delivering higher productivity for applications in remote or low-powered areas.

Bolting applications occur in nearly all industry sectorsincluding power generation as well as mining, shipbuilding, construction, oil and gas and MRO, said Brian Alexander, Global Product Manager – Pumps & Valves at Enerpac. To drive the tools that provide reliable connectionsfor erecting wind turbines and much moreits crucial to use a power pump that will perform with consistent, reliable power and can withstand demanding environments.

Alexander added, Enerpac has a long tradition of providing job-site ready, easy-to-use and efficient pumps for all these applications. The addition of the ZUTP1500 Electric Tensioner Pump with Remote Controlled Valve enhances this comprehensive product line, providing an ideal solution that is constructed for optimal performance and to withstand the demands of wind turbine and additional applications.

The simple-to-operate ZUTP1500 includes a 20-foot pendant cord for remote control of both the motor and valve, delivering hassle-free operation and increased productivity. This is ideal for wind turbine bolt tensioning applications, since it allows single-person operation. For improved visibility and safety, a large 6-inch pressure gauge with a polycarbonate cover is prominently displayed on the front panel. Additionally, a user-adjustable pressure control valve is mounted on the front panel for easy access, allowing the user to safely and precisely set the pressure. The ZUTP1500 is compatible with all brands of tensioners that require up to 1500 bar (21,750 psi) of pressure.
