Seal-less Design Advantages

When we say “Simply Built to Last”, we mean it!

Hydra-Cell positive displacement diaphragm pumps feature a seal-less pumping chamber so there are no seals, packing or cups to leak or replace. The seal-less design and check valves enable Hydra-Cell to handle abrasives and particulates that would damage other types of pumps.
In addition, Hydra-Cell can run dry indefinitely without damage to the pump.
The multiple-diaphragm design of Hydra-Cell provides virtually pulse-less, linear flow without the need for expensive pulsation dampeners.


When we say “Simply Built to Last”, we mean it! Wanner Engineering understands the need to keep plant and equipment running day after day without interruption. Hydra-Cell Heavy Duty Pumps are designed and built, above all else, for precise performance and long life.


Wanner Engineering Hydra-Cell Heavy Duty Pumps have proven their performance and reliability in some of the toughest industrial equipment and process applications.


Heavy-duty industrial pumps for the processing industries, car wash facilities, plus OEM, and agricultural and landscaping applications.



Real Savings from using Hydra-Cell pumps

  • Can save approximately 30% to 50% on initial costs because Hydra-Cell uses lower horsepower motors to achieve the same flow rates and pressures as other pumps.
  • Compact design with smaller footprint provides more efficient use of floor space.
  • Operates at 85-90% energy efficiency to reduce operating costs.
  • Seal-less design reduces maintenance and repair expenditures and minimizes the cost of spare parts compared to other types of pumps.


Hydra-Cell pumps can deal with abrasive liquids

  • Tolerates abrasive solids and particulate matter up to 800 microns (depending on pump model) and 9 hardness (Mohs) without the need for fine filtration.
  • Multiple diaphragms provide virtually pulse-less flow that exceeds API 675 standards for accuracy, linearity, and repeatability.
  • Low-shear pumping action ensures integrity of long-chain structures.


Hydra-Cell pumps are environmentally friendly

  • Liquids are 100% sealed from the atmosphere.
  • No leak path for toxic vapors or harmful gasses.
  • No seals to leak any Volatile Organic Compounds (VOC).
  • Lower energy costs to operate pump.


Versatility of Hydra-Cell pumps is unmatched

  • Variety of styles and models to pump a wide range of flow capacities and pressure ratings.
  • Hydraulically-balanced diaphragms can pump low-to-high- viscosity liquids throughout the entire pressure range of the pump.
  • Available in a variety of construction materials to meet a wide range of applications and ensure optimum pumping life even when handling aggressive fluids.
  • Can be fitted with SAE, ANSI or DIN flanges as well as IEC or NEMA motor mounts.
  • Can be provided with ATEX certification or other certification to adapt to specific applications or meet international standards.
  • Design allows for easy interchangeability of pump head materials and can accommodate mixing different materials with one pump head.


Hydra-Cell pumps are most reliable

  • Can run dry without damage to the pump.
  • Robust design tolerates non-ideal operating conditions.
  • No seals, packing or cups to leak or replace.
  • Typically runs up to 6,000 hours between lubricating oil changes.
  • Can pump acids, slurries and liquids containing up to 40% of non-dissolved solids.
  • Does not rely on the fluid being pumped for lubrication.
  • No tight tolerances susceptible to corrosion or solid particles.

  • “If the owner of a plant wants cost-effective pumps... he will buy pumps with the lowest Life Cycle Cost. Hydra-Cell is simple in construction, less elaborate in design and physically smaller for equivalent flow/pressure performance. These differences can substantially affect both purchase and operating costs.”
