JH Series High Head Dewatering Pumps

The JH Series Advantage: High-Head Performance for Demanding Dewatering

The BJM Pumps JH Series Submersible Pumps are engineered for high-head dewatering applications where increased discharge pressure is required. Designed to move water over longer distances or higher elevations, this series delivers reliable performance in sump systems, construction sites, and industrial dewatering environments.

With head capabilities reaching up to approximately 145 feet and a durable, side discharge design, the JH Series is built to handle demanding conditions where standard dewatering pumps may fall short.

Engineered for High Pressure and Efficient Flow

The JH Series utilizes a high-speed 2-pole motor operating at approximately 3450 RPM to generate strong hydraulic performance. This enables the pumps to produce higher head pressure while maintaining efficient flow rates across multiple models.

The side discharge configuration supports easy installation and compatibility with guide rail systems, making these pumps well suited for sump basins and fixed installations. With solids handling capability up to 3/8 inch, the series can manage lightly contaminated water without sacrificing performance.

Key Features & Benefits

• High-Head Capability: Delivers up to ~145 ft of head for demanding applications

• Efficient Flow Performance: Supports strong flow rates across the series

• Side Discharge Design: Simplifies installation and maintenance in sump systems

• Durable Construction: Cast iron pump body with 304 stainless steel motor housing

• Advanced Seal System: Double mechanical seal with additional lip seal protection

• Seal Minder® Option: Moisture sensing probe provides early warning of seal failure

Built for Reliability and Continuous Operation

The JH Series is designed with durability and reliability in mind. A double mechanical seal system, combined with a separate lip seal, provides enhanced protection against fluid intrusion and extends service life in continuous-duty applications.

Built-in thermal and amperage overload protection helps safeguard the motor during operation, while rugged materials ensure resistance to corrosion and wear. These features allow the pumps to perform consistently in demanding environments where uptime is critical.
