SRZS & SEMA Series

SRZSSERO Series Side Channel Pumps are specifically designed for services such as liquefied gas, refrigerant transfer, boiler feed, Condensate, biodiesel or other low NPSHa, low specific gravity, low to moderate flow, high pressure service requirements.

APPLICATIONS
For the applications noted above and many more, where high-differential pressure is necessary or low NPSH conditions exist, the SERO Series SRZS or SEMA Series multistage side-channel is the pump of choice.

SEMAFLEXIBILITY
The SERO side channel pumps are offered in six different sizes, each ranging from one to eight stages. This provides for a wide range of pressures, capacities, with flow rates from 1 – 186 GPM at total dynamic heads up to 1150’ for the SRZS and flow rate from 1 – 106 GPM at up to 1000’ TDH for the mag-drive SEMA Series.

DESIGN
The SERO SRZS and SEMA Series pumps utilizes an integral centrifugal and side channel design to create flow characteristics which enable the pump to handle up to 50% entrained vapor and low NPSH conditions. The multi-stage modular side channel design which features one to eight open radial-vane impellers is capable of working pressures to 580 psi (40 bar).
