Regarding water ring vacuum pumps + atmospheric injection

2009-03-17View Original

Thread Content

:):):) I’m looking for a small vacuum pump with a system pressure range of 3–5 kPa. I found that the maximum pressure achievable with a water ring vacuum pump combined with atmospheric injection is 1.5 kPa, which meets the requirements. I wonder if anyone has used this type of pump before – could there be any issues? Is the price also much higher than that of the non-enhanced jet version? If it’s much higher, then a rotary vane vacuum pump is the only option to consider~
