Many processes need high pressure ingredients and therefore pumps. The process then results in a high pressure product and rather than wasting the mechanical energy in this product a Recovery Turbine can be used reclaim the energy by driving the pump. Of course the high pressure product isn’t available at startup so an Electric Motor driven pump is necessary. Rather than two pumps a dual drive can be used maintaining the flexibility but reducing the cost and footprint.
Pumps are generally intermediate speed devices often with sensitive shaft systems requiring self supporting encased SSS Clutches. The recovery turbines normally need more maintenance than the pump itself so the ability to overhaul the turbine without stopping the pump can be required. SSS has features to allow this.
