Types of Diaphragms – the PulsaPro 680, 880, and 7120 offer the Flat Diaphragm, HYDRAtube,
and HYDRAcone. Additionally, you can utilize our Double Diaphragm (Flat) with PULSAlarm Leak
detection. (Figure 4 showing the Flat diaphragm, HYDRAtube, and HYDRAcone)

Flat Diaphragm – is the standard design ensuring high performance metering in a
leak-free operation. PulsaPro flat diaphragms are available in a variety of both
metal and plastic materials and can handle a wide range of chemicals. As with
PulsaPro diaphragm constructions, the flat diaphragm is hydraulically balanced
and operates stress free, providing exceptional life and accuracy.
Figure 5
HYDRAtube – is the best choice for sheer sensitive, high viscosity fluids and
slurries. It’s straight flow through design eliminates clogging and flow restrictions.
It offers double diaphragm safety as a standard as well as optional slurry valves.
Available in FKM, CSM, or PFA, it can be utilized with the most corrosive or acidic
chemicals. Optional ChemAlarm leak detection system monitors the electrical
conductivity of the intermediate liquid between the HYDRAtube and second
diaphragm to detect diaphragm failure and, can signal an alarm or stop the pump.
