Gentle pressure. Powerful results.
Pulsation dampening with air vessels or diaphragm surge suppressors.
As with all oscillating piston pumps, the crankshaft drive and the inertia of the liquid columns in our systems cause natural pressure fluctuations in the flow. However, these so-called pulsations can be effectively reduced—and this is exactly where our damping technology comes into play.
In the simplest case, pulsation damping is achieved via an air reservoir, in which a defined volume of air compensates for pressure fluctuations and stabilizes the flow.
For applications involving high pressures or sensitive processes, we recommend the use of diaphragm shock absorbers. They respond particularly quickly, reliably separate the fluid from the damping volume, and ensure smooth, low-pulsation operation—even under demanding conditions.
The result: smooth operation, less vibration, reduced stress on piping and fittings—and thus a longer service life for the entire system.
Precisely controlled. Reliably sealed.
Ventiltechnik für höchste Ansprüche.
Valves play a central role in every piston-diaphragm pump: They regulate the flow rate, prevent backflow, and thus ensure stable, controlled operation—even under fluctuating pressures or high solids content.
Depending on the application, our Emmerich pumps utilize various valve types—ranging from ball and seat valves to specially designed check valves. All variants feature a robust design, are easily accessible, and are engineered for a long service life.
Through carefully selected materials and precise manufacturing, we achieve optimal sealing performance, minimal leakage, and reliable operation even under extreme conditions.
The result: high efficiency, precise dosing, and maximum operational reliability—valve technology that only Emmerich can deliver.
