Hydra-Cell® Q Series Pumps Design Advantages


Q155 pump

T and Q Series pumps feature the Hydra-Cell seal-less design, eliminating cleanup costs from leaking seals or packing and protecting operators from dangerous fluids such as those containing hydrogen sulfide (Q155 shown).

Exclusive Seal-less Diaphragm Design

  • Seal-less design separates the power end from the process fluid end, eliminating leaks, hazards, and the expense associated with seals and packing
  • Low NPSH requirements allow for operation with a vacuum condition on the suction - positive inlet 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
  • Provides low-pulse, linear flow due to its multiple diaphragm design
  • Lower energy costs than centrifugal pumps and other pump technologies
  • Rugged construction for long life with minimal maintenance
  • Compact design and double-ended shaft provides a variety of installation options

* Consult factory for correct component selection for temperatures above 180 ̊F (82 ̊C) or below 40 ̊F (4 ̊C)
