The pumps work at high speed, delivering a small volume from each cell but at high frequency. Wanner says they can be physically smaller in relation to flow capability and consequently less expensive to acquire and operate.  

Hydra-Cell’s multiple diaphragms work in sequence to produce a virtually pulseless liquid flow, removing the need for pulsation dampeners in most installations, saving further installation and maintenance costs. Pipe strain and system leaks are also reduced.

The pumps are said to be energy efficient (80% and above), which also reduces power requirement and energy costs. 

They have no dynamic seals, cups or energy sapping packings through which hazardous fluids might escape or through which air could enter the system on the suction stroke to cause degradation or crystallisation of the pumped liquid. And, importantly, Hydra-Cell pumps require no expensive seal maintenance.
