Design
Glandless circulation pump with screwed connection or flange connection.
Application
Hot-water heating systems of all kinds, industrial circulation systems, air-conditioning systems and closed cooling circuits
Type key
| Example: | TOP‐S 40/10 | | TOP-S | Standard pump (screw-end pump or flange-end pump) | | 40/ | Nominal connection diameter | | 10 | Nominal delivery head [m] at Q = 0 m3/ h |
Special features/product advantages
- Collective fault signal as potential-free contact (depending on type)
- Direction of rotation indicator light for displaying the correct sense of rotation (only with 3~)
- Pump housing with cataphoretic (KTL) coating protects against corrosion due to condensation formation
Technical data
- Permitted temperature range -20 °C to +130 °C,
for short periods (2 h) up to +140 °C (TOP-S 25/13, 80/15, 80/20 and pumps with Wilo-Protect-Module: -20 °C to +110 °C) - Mains connection:
- 1~230 V, 50 Hz (depending on type)
- 3~230 V, 50 Hz (with optional switching plug)
- 3~400 V, 50 Hz
- Protection class IP X4D
- Screwed connection or flange connection (depending on type) Rp 1 to DN 100
- Max. operating pressure, standard version: 6/10 bar or 6 bar (special version: 10 bar or 16 bar)
