A feature of Hydra-Cell pumps is their ability to operate over a wide range of pressures. The hydraulic positive displacement pumping action maintains flow rate irrespective of pressure and the seal-less design ensures that this holds true throughout the life of the pump.

High pressure pumping of abrasive, non-lubricating, corrosive liquids and recycled liquids containing solids can be done reliably because of the seal-less design of the Hydra-Cell pump.

Many chemicals appear not to contain solid particles but in practice may contain solid crystals due to exposure to air or temperature changes. Hydra-Cell's seal-less design and horizontal spring loaded check valves enable these situations to be handled reliably.

High pressure pumps with dynamic seals e.g. piston/plunger pumps and axial piston pumps  may require frequent  seal maintenance and fine filtration arrangements to keep the process running. Seal-less design eliminates these requirements.
