Types of Kerr HDD Pump Series

The Kerr HDD pump series produced by our company mainly include the following types:

Piston KERR KA-3500PT Pump

The fluid end of the KERR KA-3500PT pump is the core component for achieving high-pressure fluid delivery. Its design, material selection, and manufacturing process directly determine the pump's performance, durability, and adaptability to different operating conditions.

Plunger KERR KP-3300PT Pump

The fluid end is the part of the pump that directly contacts the fluid being pumped. Its design and material selection directly impact the pump's corrosion resistance, wear resistance, pressure handling capability, and adaptability to different fluids.

Piston KERR KZ-3150PT Pump

Horizontal Directional Drilling (HDD) for pumping drilling fluids (e.g., bentonite mud) or other auxiliary fluids. Its 16.7 BHP power, approx. 1600 PSI pressure, and approx. 30 GPM flow specifications make it suitable for small to medium-sized HDD rigs.
