KHD / KHH Series High Flow, High Head Abrasion-Resistant Dewatering Pumps

The KHD/KHH Series Advantage: Extreme Head and Flow Performance

The BJM Pumps KHD and KHH Series are designed for high-flow, high-head dewatering applications in the most demanding environments. Engineered to deliver both exceptional lift and large volume capacity, these pumps are ideal for deep excavation, mining, and heavy industrial dewatering operations.

With head capabilities exceeding 400 feet and flow rates approaching 1000 GPM, the KHD/KHH Series provides powerful, reliable performance in applications where standard dewatering pumps are no longer sufficient.

Engineered for Demanding Dewatering Applications

The KHD Series utilizes a single-stage hydraulic design optimized for high flow and strong head performance. For more extreme lifting requirements, the KHH Series incorporates a dual-stage design, allowing for significantly higher discharge pressures.

Heavy-duty construction features abrasion-resistant materials throughout, ensuring durability in applications involving sand, silt, and fine solids.

Key Features & Benefits

• High Head Capability: Delivers up to ~400+ ft of head

• High Flow Performance: Handles up to ~1000+ GPM

• Single & Dual Stage Designs: KHD (single-stage) and KHH (dual-stage) options

• Abrasion-Resistant Components: Hi-chrome iron impeller with ductile iron wear components

• Heavy-Duty Construction: Designed for continuous operation in harsh conditions
