DAB.EVOPLUS B 80/360.80 M flanged circulation pump with electronic speed control for heating and air conditioning

Product detailed description

DAB.EVOPLUS B 80/360.80 M (code 60150989) is a wet rotor circulation pump with a synchronous motor with permanent magnets, whose speed is controlled by a frequency converter. It belongs to the EVOPLUS range intended for larger heating, ventilation and air conditioning systems – apartments, family houses, schools, hospitals or administrative buildings. This model has a simple flanged version with a single-phase motor, DN 80 connection and a construction length of 360 mm.

Performance of the EVOPLUS B 80/360.80 M model

The pump achieves a pumping head of up to 8 m and a flow rate of up to 42.84 m³/h, with a maximum input power P1 of 670 W. With an energy efficiency index EEI ≤ 0.19, it complies with the ErP 2009/125/ES directive. The electronics continuously evaluates changes in the system hydraulics, for example when opening and closing individual branches, and adjusts the speed accordingly – the circuit receives the required flow without unnecessary energy consumption.

Control and connection to the control system

• proportional (Δp-v) or constant (Δp-c) differential pressure, constant curve and regulation depending on the liquid temperature
• economical function and remote switching on and off
• inputs for an analogue signal 0–10 V or 4–20 mA, PWM signal and temperature sensor, output for fault indication
• ModBus communication, LonBus with an additional module
• OLED display and three buttons on the control panel

Construction

The pump body is made of cast iron, the impeller is made of technopolymer and the stainless steel shaft rotates in ceramic bearings lubricated by the pumped liquid; the motor housing is made of pressure-cast aluminium. The suction and discharge nozzles have threaded connections for pressure and temperature measurement. Thermal insulation of the body is part of the delivery – it reduces heat losses and condensation formation, so the pump can also handle cooling circuits with liquid colder than the surroundings. The motor does not require external protection: the electronics protects it against overload, overheating, phase failure and overvoltage and undervoltage.

Installation and operating conditions

The pump must always be installed with the motor shaft in a horizontal position, the control electronics must be in a vertical position and must not be insulated. The pumped liquid must be clean, without solid particles and mineral oils, with a glycol content of up to 30 % and a temperature from −10 to +110 °C; the ambient temperature may be up to 40 °C. The maximum operating pressure is 10 bar and at least 20 m w.c. must be maintained on the suction side at 90 °C, or 25 m w.c. at 100 °C. Flanges DN 80 PN 10 are not part of the packaging, they are supplied on request. The cast iron version is not intended for potable water. Electrical connection (1 × 220–240 V, 50/60 Hz) and commissioning must be carried out by a qualified person.

Technical parameters

Frequently asked questions

What does the designation EVOPLUS B 80/360.80 M mean?
B indicates a simple flanged version, 80 is the maximum pumping head in decimetres (8 m), 360 is the construction length in millimetres and 80 is the nominal flange DN 80. The letter M means a single-phase motor 220–240 V.

Are the flanges part of the packaging?
No, the flanges DN 80 PN 10 are supplied on request with the pump. The thermal insulation of the body is included in the packaging, however.

Which Grundfos pump can be replaced by this model?
The comparison table in the IVAR technical sheet lists EVOPLUS B 80/360.80 M as an equivalent for Grundfos MAGNA 1 80-80 F and MAGNA 3 80-80 F. Before replacement, please check the construction length, flange and system operating point.

In which position is the pump installed?
Always so that the motor shaft is horizontal and the control electronics is vertical. Do not insulate the electronics and do not cover the condensate discharge openings.
