Electronic circulator pump DAB.EVOSTA2 40-70/130 1" for heating systems – SALE

Product detailed description

The DAB.EVOSTA2 40-70/130 1" is an electronic circulator pump for wet heating systems and air-conditioning circuits. Its permanent-magnet synchronous motor and frequency converter let it track pressure changes in the system and adjust its output accordingly, keeping power consumption low.

Also suitable as a replacement

The 130 mm installation length and the connection match older three-speed pumps such as the VA series, so the EVOSTA2 is also a good replacement for them. A single model covers heads of 4, 5 and 6 m, which previously required different pumps.

Controls

• a single MODE button on the front panel, three LEDs show the selected setting
• 9 settings: proportional pressure PP1–PP3, constant pressure CP1–CP3 and constant speed I–III
• the vent plug also allows the shaft to be released by hand

Construction

• cast iron body with cataphoresis coating, stainless steel motor casing
• technopolymer impeller, ceramic shaft in graphite bearings lubricated by the pumped liquid
• watertight electronics rated IPX5, insulation class F
• built-in protection against overload, overheating, overvoltage and undervoltage – no external motor protection required
• pump body with G 1 1/2" thread (DN 25), 1" union connection

Operating conditions

The pump handles clean, chemically neutral liquids free of solid particles and mineral oils, with properties similar to water and no more than 30 % glycol. Liquid temperature can be −10 to +110 °C, operating pressure 1 to 10 bar and ambient temperature up to 40 °C. Install it with the motor shaft horizontal; the arrow on the body shows the flow direction.

Single-phase supply 1 × 230 V, 50/60 Hz. Have the electrical connection made by a qualified person. The pump meets the requirements of the ErP Directive 2009/125/EC.

Technical data

Frequently asked questions

Can I replace an old three-speed circulator with this pump?
Yes, the EVOSTA2 40-70/130 1" has a 130 mm installation length and the same connection as common older pumps such as the VA series. One model also covers heads of 4, 5 and 6 m.

Which control modes does the pump offer?
The MODE button selects one of 9 settings: proportional pressure PP1–PP3, constant pressure CP1–CP3 and constant speed I–III. Three LEDs on the panel show the chosen setting.

What connection does the 1" version have?
The pump body has a G 1 1/2" thread (DN 25) and connects to the pipework with a 1" union. The installation length is 130 mm.

Is the pump suitable for antifreeze mixtures?
Yes, the pumped liquid may contain up to 30 % glycol. It must be clean and free of solid particles and mineral oils, at a temperature between −10 and +110 °C.
