EVOSTA2 25-105/130 SOL (1/2") Electronic circulation pump for solar systems

Product detailed description

EVOSTA2 25-105/130 SOL (1/2") Electronic circulation pump for solar systems

Electronic circulation pumps EVOSTA2 SOL with a synchronous permanent-magnet
motor and a frequency converter designed for solar systems. This range of circulation pumps
ensures high efficiency in all applications and delivers significant energy savings.
The pump contains an electronic device that detects pressure changes in the system and automatically
adjusts output, ensuring maximum efficiency with minimum energy consumption.
All models have a single sequential control button, an air-vent plug, and allow
manual release of the motor shaft. The cast-iron body has a cataphoretic coating, and the housing is made of stainless
steel. A version controlled by an external PWM signal is available (1.5 m power cable).

• Operating range: from 0 to 4 m3/h with a head of up to 14.5 m
• Liquid temperature range: from -10°C to + 110°C (130°C at 60°C ambient temperature)
• Maximum working pressure: 10 bar (1000 kPa)
• Protection class: IPX4
• Insulation class: F
• Installation: with a horizontal motor-shaft position
• Voltage: 1x230 V/50/60 Hz
• Pumped liquid: clean, free of solid particles and mineral oils, non-viscous, chemically neutral, with properties close to water (max. glycol content 50%)

Frequently Asked Questions

• How do I choose the right pump output/head? It must cover the pressure losses of your specific circuit (pipe length, number of fittings) - if in doubt, consult a heating engineer who can size the pump precisely for you.
• Must installation be done by a professional? Fitting the pump into a prepared pipe run can be handled by a skilled DIYer, but we recommend having the electrical connection and system balancing checked by a professional.
