SIHI Modular Multistage Pump

SIHICapacity: 1100 GPM Total Head: 2100 Ft. Temperature: to 356°F Models MSM, MSL. SIHI multi pump range of horizontal or vertical ring-section multistage pumps for high pressure and Low NPSH applications


Sihi Side Channel Pump

SIHICapacity: to 160 GPM Heads: to 1000 FT. Temperature: to 350°F Air or Gas Content up to 50% Models ADH, AEH, AKH, AOH. SIHI Side channel pump vapor handling and self priming capability make it exceptional along with a unique lateral channel design that permits the impellers to float, reducing wear and eliminating end thrust on bearings while still maintaining radial and axial balance

Model CEH low NPSH

SIHIModel CEH low NPSH pumps are a combination of the normal self-priming side channel pump with the addition of an initial centrifugal suction stage making possible an optimum suction requirement and thus superior low NPSH performance. NPSH values are as low as 0.5ft can be achieved. The special design of the stages provides excellent gas handling capabilities making it particularly suitable for handling liquefied gases such as ammonia, refrigerant liquid gas, LPG, propane, butane, and liquefied natural gas and many other difficult liquids
