Grundfos TPD 80-250/2 A-F-A-BQQE-MW1 (93428459)
Single-stage, close-coupled, volute twin-head pump with in-line suction and discharge ports of identical diameter. The twin-head pump is designed with two parallel power-heads. The pump is of the top-pull-out design, i.e. the power head (motor, pump head and impeller) can be removed for maintenance or service while the pump housing remains in the pipework. Each power head is fitted with an unbalanced rubber bellows seal. The shaft seal is according to EN 12756. Pipework connection is via PN

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.
