Applications
- Commercial air conditioning — Improve user comfort and reduce life-cycle costs with intelligent pumps that integrate easily into your air-based or hydronic cooling system.
category
- Inline single stage pumpsIn-line single-stage pumps are typically used in commercial buildings for air-conditioning and heating applications. The pumps are equipped with standard motors and mechanical shaft seals. They are close-coupled, meaning that the pump and motor are two separate units, making them less sensitive to impurities in the pumped liquid.
