JHF Series High Head / High Temperature Dewatering Pumps Information

Features & Benefits

The JHF Series is engineered for demanding applications requiring both high discharge pressure and resistance to elevated temperatures. Its ability to operate in liquids up to 200°F makes it suitable for industrial environments where heat and pressure are critical factors.

The series delivers strong hydraulic performance while maintaining durability and reliability, ensuring consistent operation in continuous-duty applications. The inclusion of Seal Minder® monitoring provides an additional layer of protection by helping detect seal failure early.

Construction and Operational Design

The JHF Series combines cast iron hydraulic components with a 304 stainless steel motor housing, providing durability, corrosion resistance, and long service life in harsh environments.

Each pump features a double mechanical seal system with an additional lip seal, creating multiple layers of protection against fluid ingress. The submersible motor operates at approximately 3450 RPM and is designed for continuous-duty service in high-temperature conditions.

Class R insulation supports operation in elevated temperatures, while built-in thermal switches embedded in the windings help prevent overheating and motor damage.
