STH-Series Pumps
Home/
The STH Series are designed for high head applications. With capabilities of up to 253’ of head the STH Series eliminates the need for a separate booster pump which translates to reduced maintenance and a simpler, more reliable solution.
The STH design runs at a slower RPM, while providing larger shafts and bearings to support the high head hydraulics. The result is a pump that outperforms the competition in both durability and performance by up to 20%.
