Hydra-Cell Sealless Pumps Q155 Series

Employ a Hydra-Cell Sealless Pump for Reliable Performance in Challenging Applications.

Sealless Design. Damage-Free Operation.

Q155 Series pumps employ the Hydra-Cell seal-less design, which separates the power end from the process fluid end, eliminating leaks, minimizing hazards, and avoiding the expenses associated with leaking seals and packing.

Hydra-Cell Positive Displacement Diaphragm Pump Features

  • Low net positive suction head (NPSH) requirements enable operation with a vacuum condition on the suction. Positive suction pressure isn’t needed.
  • These sealless pumps can work with a blocked or shut suction line and can run dry indefinitely without damage, avoiding the costs of downtime and repair.
  • The hydraulically balanced diaphragms handle high pressures with little stress.
  • Their rugged construction ensures long life with rare maintenance.

For Comparison

  • The proprietary diaphragm design handles more abrasives with less wear than screw, gear or plunger pumps.
  • Hydra-Cell positive displacement diaphragm pumps are far more efficient than multi-stage centrifugal pumps (H-pumps).
