Patented Early Recognition of Failures

The Schäfer Pumpen & Hydraulik SUMO Monitoring-System observes oscillating displacement pumps reliable while in operation

SUMO – Heavyweight protection for your pump

Defect detected – damage deflected: Thanks to the patented Schäfer Pumpen & Hydraulik Monitoring System SUMO, damages in piston pumps can be discerned before they occur. Based on the mathematical analysis of selected parameters, the system is able to calculate imminent failures or damages reliably. 

Special sensors are thus used to continually evaluate the pumps‘ functionality and communicate the results to the SUMO software. The outcome can be comfortably viewed online.

SUMO can be introduced to new systems or retrofitted to existing pumps. Its modular design allows for gradual integration and commissioning of the one-of-a-kind Condition Monitoring System. Hence, individual system components can also be serviced during operation, saving time and cost. 

The system was developed in cooperation with the Institute for Process Machines and Industrial Manufacturing Equipment at the University of Erlangen, Germany.
