Bowie Pumps

The Pump Behind Every Productive Hydroseeding Operation

For decades, Bowie rotary gear pumps have been trusted to move some of the toughest slurries in the industry. Designed specifically for hydroseeding, erosion control, and other demanding pumping applications, Bowie pumps are engineered to deliver consistent flow, dependable pressure, and long service life under real-world jobsite conditions.

Whether installed on a Bowie Hydro-Mulcher®, integrated into a custom hydroseeding system, or used as a replacement pump, Bowie gear pumps are built to handle abrasive materials, thick mulch slurries, bonded fiber matrix (BFM) products, and hydraulic growth media with confidence.

Their positive displacement design provides reliable output through long hose runs while maintaining the pressure needed for efficient application.
