Putzmeister America, Inc. Implements New Pump Test System


“The new pump test system is more dependable and efficient than the old procedures,” says Stefan Höfling, developer of control and measuring systems for the global Putzmeister organization. Putzmeister America has installed three of the new testing stations at its Sturtevant, Wisconsin manufacturing facility.

An average of 170 checks are completed on each pump with the computerized pump testing system.

The testing begins with transducers that are plugged into 12 points on the gauge port central panel on the machine.

As the tests are completed, the system relays information from the pump to one of the three computer stations. In addition to the stationary computer station, the transducers also relay the test information to wireless handheld tablets (shown above) technicians use while working on the pumps.

Company continues is commitment to unparalleled quality control

STURTEVANT, WI (February 1, 2008) – In December 2007, Putzmeister America, Inc. implemented its new computerized pump testing system which will improve their quality control.

The computerized pump testing system is an extension of testing procedures in place at Putzmeister’s global headquarters in Achital, Germany, where eight testing stations are currently in use. Putzmeister America has installed three of the new testing stations at its Sturtevant, Wisconsin manufacturing facility.

“The new pump test system is more dependable and efficient than the old procedures,” says Stefan Höfling, developer of control and measuring systems for the global Putzmeister organization. “It has proven highly successful at Putzmeister Iberica’s operation in Madrid and we expect nothing less here in North America.”

Before any type of testing is performed on a unit, tests of all sensors and systems are done to ensure accurate readings. The next step is performing the tests using a customized test checklist based on the options of the machine.

The testing begins with transducers that are plugged into 12 points on the gauge port central panel on the machine.

“Using transducers as opposed to the gauges used in the old process provides a higher level of accuracy,” comments Steve Baumstark, test stand manager for Putzmeister America. “As the tests are completed, the system relays information from the pump to one of the three computer stations.”

In addition to the stationary computer station, the transducers also relay the test information to wireless handheld tablets technicians use while working on the pumps.

“The computerized test program walks the test stand technician step-by-step through the testing process and along the way records all hydraulic adjustments and machine performance,” notes Baumstark. “It’s all automatic and very accurate.”

An average of 170 checks are completed on each pump with the computerized pump testing system. The machine cannot pass the test operation until all the hydraulic adjustments and checks are performed and meet tolerances for that particular machine.

The computerized pump testing system has not only added a higher level of excellence to tests conducted, it has made all testing more efficient and manageable. For example, the performance throttle test which checks the performance of the pump and chassis is far easier and less time consuming that ever before.

“Another reason this improved testing process is beneficial,” says Baumstark, “is that the system is accessible by authorized personnel from anywhere in the world, by logging onto the Putzmeister America network. We can also clearly view all of the readings and information on one screen, whereas before it was not physically possible to view everything at once.”

An on-demand printable record for authorized personnel is just one more feature of the new system. This test information goes with each model’s information in the Active Machine Binder Electronic Record (AMBER) system, and can be reviewed as necessary.
