Q155 Medium Pressure

Q155 Series Quintuplex Pumps

Versatile, Reliable Pumps for a Wide Range of Applications

  • Seal-less design eliminates leaks, hazards and the expense associated with seals and packing
  • Low NPSH requirements allow for operation with a vacuum condition on the suction - positive suction pressure is not necessary
  • Can operate with a closed or blocked suction line and run dry indefinitely without damage, eliminating downtime and repair costs
  • Unique diaphragm design handles more abrasives with less wear than gear, screw or plunger pumps
  • Hydraulically balanced diaphragms to handle high pressures with low stress
  • Lower energy costs than centrifugal pumps
  • Rugged construction for long life with minimal maintenance
  • Compact design and double-ended shaft provide a variety of installation options
