Electronic circulator pump DAB EVOSTA2 40-70/180 – for a system built with 1'' pipe (1 1/2'' union), head 7 m, flow 3.6 m³/h, power 35 W

The DAB EVOSTA2 40-70/180 pump is a highly efficient solution for circulating heat energy in heating systems made with 1'' pipes and a 1 1/2'' union connection.

This innovative electronic circulator pump is ideal for both new installations and for replacing old three-speed models.
 

Main advantages:

• Energy saving:
  Thanks to the built-in frequency converter and the permanent magnet synchronous motor, EVOSTA2 achieves an energy efficiency index EEI ≤ 0.18, making it one of the most efficient on the market.

• Convenient setup:
  One button for sequential mode switching – no complicated menus. Easy access to the motor shaft for manual unlocking if needed.

• Exceptional reliability:
  IPX5-rated moisture protection, self-lubricating design and internal motor protection – no need for external overload protection.

• Strength and durability:
  Cast iron housing with cataphoretic coating, stainless steel rotor, ceramic shaft and bushings, EPDM seals – all designed for trouble-free long-term operation.

Applications:

• Heating systems in single-family houses
• Replacement of old circulation pumps
• Constant and variable flow systems

Features:

• Operating range: 0.4 - 3.6 m3/h with head up to 6.9 meters
• Fluid temperature range: from -10 °C to +110°C
• Working pressure: 10 bar (1000 kPa)
• Protection class: IPX5
