Applications
- Commercial heating — In a commercial heating system, energy-efficient pumps are only half the story. But with the right system design, you can truly reap the benefits and significantly reduce the energy bill.
category
- Endsuction long coupled single stageEnd-suction long-coupled single-stage pumps are ideal for large-scale industrial applications. As with all end-suction pumps, the liquid runs directly into the impeller and the inlet and outlet form a 90 degree angle to each other. The long-coupled design makes the pumps easy to service and maintain.
