The Hydra-Cell range of seal-less, high-pressure diaphragm pumps from Michael Smith Engineers is suitable for high- and low-pressure applications that involve corrosives, abrasives, slurries or non-lubricating liquids.

The pumps have a compact, multi-diaphragm design that saves space and helps to reduce maintenance costs. For most applications, there is no need for pulsation dampeners.

The pumps are available in a selection of liquid end materials, ensuring their ability to handle most ‘challenging’ fluids. They have been successfully used in applications such as metering, dosing, injecting and spraying chemicals, solvents, acids, hydrocarbons, natural gas liquids, alkalis, polymers, aqueous ammonia, resins, slurries and recycled and dirty liquids.

The absence of seals, cups or packing eliminates the issues associated with seal failure and therefore lowers maintenance costs. The pumps can also be run dry without damage.

Key features and specifications

  • Flow rates of up to 140 litres/minute
  • Maximum discharge pressures between 70 bar and 170 bar (depending on model)
  • Rugged durability and excellent pumping accuracy
  • Ability to operate with true positive displacement for optimum energy efficiency (more than 85 per cent)
