The Netherlands: Enerpac Presents Improved ZUTP1500 Electric Tensioner Pump
Enerpac introduces the ZUTP1500 Electric Tensioner Pump with Remote Controlled Valve. The ZUTP1500 is the latest addition to the company’s robust line of ZUTP-Series Electric Tensioner Pumps, which feature 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.
Excellent suitable for use in heavy industries
Designed for the demanding needs of diverse (heavy) industries, the new ZUTP1500 is the only electric tensioner pump on the market to feature a remote controlled electric valve and a universal motor with low amperage draw for superior performance. The resulting pump facilitates hassle-free operation of bolt tensioners and hydraulic nuts in remote locations. With a low-pressure flow rate of 3,8 l/min and a full-pressure flow rate of 0,33 l/min, 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 more reliable and offers a lower operating cost than similar competitive units and is less sensitive to contamination in the hydraulic system. Plus, the design is rugged, lightweight and compact, providing an ideal fit for tight openings common in space-restricted wind turbine applications.
Perfect combination with bolt tensioners
The Enerpac Bolting Tools product line consists of a complete range of professional tools for bolting, tightening and tensioning. The feature-rich pump is jobsite ready and built for fieldwork. It follows naturally that the pump is ideally suited for use together with the Enerpac bolt tensioners.
The ZUTP1500 includes a durable, lightweight aluminium 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 bolting applications in remote or low-powered areas.
User-adjustable and single person operation
The simple-to-operate ZUTP1500 includes a 6 meter pendant cord for remote control of both the motor and valve for hassle-free operation and increased productivity. It allows single-person operation which makes it ideal for instance for wind turbine bolt tensioning applications. For improved visibility and safety, a large 150 mm 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 required hydraulic pressure. The ZUTP1500 is compatible with all brands of bolt tensioners that require up to 1500 bar (21,750 psi) of pressure.
“Enerpac has a long tradition of providing job-site ready, easy-to-use and efficient pump for various applications. Bolting applications occur in nearly all industry sectors—including 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 connections it is crucial to use a power pump that will perform with consistent, reliable power and can withstand demanding environments”, concludes Alexander.
