Measuring and testing devices
EPP Test Pumps
of water supply lines
EPP test pumps are specifically designed for pressure build-up during leak tests of water supply lines and offer maximum reliability in daily use. In combination with the PMS leak testing case, they operate fully automatically and in compliance with standards DVGW W400-2 and SVGW W4. Thanks to the integrated ADAMM pressure relief device with water volume measurement, tests can be carried out efficiently, safely, and without interventions in the pipe trench. The robust piston pump technology, high-quality connections, and protective functions ensure a long service life and maximum operational safety. With a test pressure of up to 25 bar and a flow rate of 14 l/min, the EPP15-14-025 model is ideally suited for professional applications in the water and industrial sectors.
