Zero-Max ETP-EXPAND® Provides Ideal Connection within Hollow Shafts for Pump Drives

Plymouth, Minnesota: Connecting a rotating piston lobe to a hollow shaft has been improved using the ETP-EXPAND®, a patented bushing device that is fast and easy to install and adjust.

The ETP-EXPAND was developed to simplify exchanging seals in pumps when fluid viscosity is changed. This is often required in pharmaceutical, chemical, food and beverage processing systems with the seal change needing to be done quickly and easily.

ETP-EXPAND is a device that connects to a hollow shaft, locking the impeller/lobe wheel of the pump motor into position using just one actuation screw. Considerable space-savings are gained by mounting within the hollow pump shaft.

No Axial Movement When Tightened

The ETP-EXPAND is a patented precision bushing designed just for pump applications. Its unique design configuration accurately expands OD of the ETP EXPAND when a single actuation screw is tightened. Since the expansion is caused by self-contained hydraulic pressure, the resulting force is perfectly even along all surfaces. Most important, the bushing aligns precisely without axial movement as it is tightened. The positioning is very accurate and takes just seconds.

Another key ETP-EXPAND feature is its robust and precise design allowing it to be actuated thousands of times with repeatable accuracy and without any axial movement. An Allen wrench is all that is required to mount and lock it into position. ETP-EXPAND has sealed, clean lines that resist debris collection and cleans easily without any special maintenance. These features increase the efficiency of the pump system for a lower total operating cost.

ETP-EXPAND is customizable to meet the demands of your pump application.
