Low NPSH – CEHA Side Channel Pumps

•The CEHA and CEHX pump  series is a combined system side channel pump.

•It is equipped with a low NPSH centrifugal impeller placed before the side channel stages.

•This NPSH inducer stage delivers enough pressure to overcome the entrance pressure loss of the first side channel stage or the required NPSH.

Application Guidelines

•High Temperature Applications (>120C / 250F)

•Cup Springs

•Cooled Mechanical Seal

•Carbon Antimony sleeve bearing

•GNZ Mechanical Seal

•Temperature Limit
