MSDB Series

MSDB Series Flooded Suction Pumps

Unique Magnetic Drive Multi-Stage Pumps

  • Ideal for high-head, low-flow applications like spray, filtration, and chemical delivery
  • Based on the proven DB Series 11/15 platform, MSDB pumps share many of the same features including sealless mag drive design
  • Each stage produces additional head allowing MSDB pumps to produce much higher heads at lower flows, allowing the use of a smaller, less expensive pump in the application
