Hydra-Cell Seal-less Pumps. Positive Displacement Pumps with 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 Seal-less Pumps 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.

Economical
- Real Savings from using Hydra-Cell Sealless pumps
- Can save approximately 30% to 50% on initial costs because Hydra-Cell Sealless Pumps use 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.
Capable
- Hydra-Cell Seal-less 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.
Environmental
- Hydra-Cell Seal-less 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.
Versatile
- Versatility of Hydra-Cell Seal-less 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.
Reliable
- Hydra-Cell Seal-less 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.
