JH Series High Head Dewatering Pumps Information

Features & Benefits

The JH Series is specifically engineered for high-head dewatering applications where increased discharge pressure is required. Its hydraulic design allows water to be moved efficiently over greater vertical distances, making it well suited for systems with elevation changes or extended piping runs.

The series balances flow and pressure to ensure consistent performance, while maintaining the ability to handle light solids typically found in dewatering environments. Optional Seal Minder® monitoring adds an extra layer of protection by helping detect seal failure before it leads to pump damage.

Construction and Operational Design

The JH Series is built with cast iron hydraulic components and a 304 stainless steel motor housing, providing both structural durability and resistance to corrosion. This combination allows the pumps to perform reliably in wet and demanding conditions.

Each pump features a double mechanical seal system, along with an additional lip seal, giving multiple layers of protection against contamination. The motors operate at approximately 3450 RPM and are designed for continuous-duty operation, delivering strong hydraulic output across the series.

Built-in thermal and amperage overload protection helps prevent motor damage during extended use, while stainless steel components improve overall durability and longevity.
