EVOSTA2 RANGE Wet Rotor Electronic Circulators - Spare Parts
Brand: Dab Pumps S.p.A
EVOSTA2 circulating pump range from DAB Pumps has a built-in electronic device that detects the changes demanded by the system, and automatically adapts the circulator performance accordingly.
ADVANTAGES
Thanks to the advanced technology employed, the permanent magnet synchronous motor and its electronic driver (also called ECM: Electronic Commutation Motor or BLDC motor: Brushless DC motor), the new range of EVOSTA2 circulators ensures high efficiency in all applications, with significant benefits in terms of energy saving.
The circulator has a built-in electronic device that detects the changes demanded by the system, and automatically adapts the circulator performance, accordingly, always ensuring optimum efficiency and minimum energy consumption.
The EVOSTA2 circulator is also suitable for replacing old three-speed circulators, both as far as size, as it has the same dimensions of the VA series, and for its capability of covering pumps with heads of up to 18 feet with one single model.
It can also simplify the work of the user, thanks to a single sequential setting button and a breather plug used to degas the system and unlock the motor shaft if required.
The EVOSTA2 circulators can operate in 3 different modes:
- Proportional differential pressure
- Constant differential pressure
- Fixed curve
- Pump body in cast iron with cataphoresis treatment EVOSTA2 SAN version with Stainless Steel
- Motor casing in stainless steel
- Motor casing cover in technopolymer
- Motor shaft in ceramic (alumina)
- IPX5: Protected against water jets
