CHP Unit Coolant Recirculation
This application note provides an overview of the successful use of magnetically coupled external gear pumps in the recirculation of water coolant within small-scale Combined Heat and Power (CHP) units.
A company that applies its expertise in small, efficient CHP units is committed to developing alternative solutions to address the challenges of reducing emissions, increasing fuel efficiency and improving energy security in the domestic home heating and electrical power generation market.
Innovations in fuel cell technology have led to the development of small-scale CHP units that incorporate fuel cells and offer energy efficiency. Gear pumps are used in the recirculation of de-ionized (ultra pure) water coolant within CHP units and to meter the flow of the water coolant. The smooth flow and accurate metering of the pump, equipped with a system of feedback, provides developers with essential data for evaluating the operating efficiencies and heat transfer characteristics of CHP units
THE PUMP SOLUTION
Micropump GA Series suction shoe design gear pumps are direct coupled to a brushless 24VDC motor with control of the input speed and a tachometer for feedback of the actual motor speeds.
|Smooth, pulse-free flow||Easy to monitor, easy to control|
|Simple to service and maintain||Reduced downtime and less production lost|
|Accurate, pulse-less output||Consistent metering of components|
|Shoe suction style gear pumps self compensate for wear||Highly efficient at high temperatures|
|Magnetic Coupling||Containment of the pumped fluid||Reduced leakage for components|
|No rotating seals to fail||Extended pump operation between servicing means reduced downtime|
|Leak free pumping||No cross contamination of the pumped fluid|
|Feedback of pump speed||Feedback of inner driven magnet speed|
