8K Multistage
Centrifugal Pumps
Designed for long-life and trouble free service, the 8K series
are a superior line of multistage centrifugal pumps. Originally
engineered for booster, water purification, and hot water
applications, many other industries have adopted this product
due to its reliable performance.
The 8K series are truly an industrial grade pump, consisting
of 304 or 316 SS hydraulic assemblies constructed with cast
stainless steel flanges for maximum installation support.
Different mechanical seal face options are available and
incorporate a separate thrust bearing in place of motor
bearings, adding to the robust design of this product. The
8K also features tungsten carbide lower pump bearings and
sleeves – standard construction for all services, providing
maximum operating life. Count on the 8K to get the job done.

Additional Centrifugal Pumps
304 Stainless Steel Casing
Centrifugal pumps offer solutions for high-flow,
low-pressure industrial pumping needs. Typical fluids
pumped include fresh water or liquids with some
suspended solids. Below is a sampling of popular
centrifugal models that include the pump, seal and
motor. Most of the pumps listed are rated at
3450 rpm, but many models are available
at 1725 rpm.
