No Seals No Packing

With no dynamic seals in the pumped liquid, the Hydra-Cell® pump does not rely on the properties of the liquid to:

• Lubricate the pumping action
• Form a seal to maintain pressure

This results in the Hydra-Cell® pump's ability to pump very thin, non lubricating liquids at high pressure reliably.

A large contributor to the operating cost of a pump in a system is the service and maintenance (unscheduled repair). In pumps with dynamic seals and packing, this can be a significant cost and rise quickly with non lubricating, corrosive or with liquids containing suspended solids. This process condition has led to many customers switching to a Hydra-Cell® pump from using Gear, Progressing Cavity, Plunger, Multistage Centrifugal and Lobe pumps. The Hydra-Cell pumps  No Seal No Packing  design reduces service and maintenance costs dramatically leading to the lowest total ownership costs.

There are many common corrosive liquids used in industrial processes such as Hydrochloric, Sulphuric, Nitric acids, De-ionised water. But also common liquids can become very corrosive as the temperature increases. So even water at 90° C  becomes a corrosive liquid.

The Hydra-Cell® pumps seal-free, packing-free  design makes it an ideal choice for handling corrosive liquids:

• Pressure injection
• Transfer
• Metering and dosing

The presence of suspended undissolved solids in a pump liquid is more common than you may think.

• Supersaturated liquids used in spray drying
• Resins and Isocyanates, Caustic, Phosphate and acidic solutions can form very small hard crystals when exposed to humidity or air
• Solids pick up from corroded pipes and tanks

It is often the small, sub 5 micron solids that do the most damage to dynamic seals and are very hard and expensive to filter out.

Seal flushing is eliminated saving cost of installation and running costs

The Hydra-Cell® pumps seal-free and packing-free design combined the special valve design ensures reliability when pumping liquids with suspended solids.
