Hydra-Cell Design Advantages

• Positive displacement with smooth low pulse output.
• Heavy-duty industrial construction for long service life in harsh conditions.
• Hydraulically-balanced, unstressed diaphragms.
• Wide range of flow rates from 0.4 to 128 l/min and pressures up to 170 bar.
• Repeatable, accurate output – ideal for metering and dosing.
• Seal-less design – can pump particles in suspension.
• Flexible installation with a variety of mounting configurations.
• Minimal maintenance.  No cups, packings or seals – can even run dry!
• Wide choice of materials of construction for pump heads, diaphragms and valve assemblies..
• High efficiency – low power consumption.
• Compact construction – physically small in relation to performance.

          

1. Drive shaft - via electric motor, hydraulic motor, belt and pulley etc.
2. Roller bearings - rigid support, immersed in lubricating oil bath.
3. Fixed-angle cam - translates rotary motion into linear to the hydraulic cells.
4. Hydraulic cells - displace diaphragms via pressurised oil.
5. Diaphragms - hydraulically balanced, no stress during flexing.
6. Inlet valve assemblies - simple design, allow liquid into pump chamber.
7. Outlet valve assemblies - allow liquid to flow into pressure discharge line.
8. Pressure regulating valve - controls outlet pressure and prevents pump overload.

Size Comparison

             

A Hydra-Cell G10 pump compared with a traditional diaphragm metering pump of similar performance.(max flow 1500 l/hr, max pressure 70-80 bar). 

Motor Spec:  Hydra-Cell G10 5kW.  Traditional pump 15kW.

Steady-State Performance

         

Pressure changes have little effect on the flow of the Hydra-Cell pump.
