We recently jacked up the base pressure levels for this line in efforts to provide cleaning professionals with the most power and features in this machine class," explained Daimer.
The IDP-3 measures 14 x 7 x 6 inches (356 x 178 x 152 mm), yet delivers a robust pumping speed of 60 L/m and a very low base pressure of less than 250 mTorr -- almost four times lower than an equivalently sized membrane/diaphragm pump.
The application uses the pump to reduce water vapor partial pressure, allowing faster product throughput, reducing base pressure and pump-down time.
