DAB.EVOPLUS B 60/240.50 M flanged circulation pump with electronic speed control, DN 50, for heating and air conditioning

Product detailed description

DAB.EVOPLUS B 60/240.50 M (code 60150971) 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 designed for larger heating, ventilation and air conditioning systems – apartments, single-family homes, schools, hospitals or administrative buildings. This model has a simple flanged version with a single-phase motor, DN 50 connection and a construction length of 240 mm.

Performance of the EVOPLUS B 60/240.50 M model

The pump achieves a delivery head of up to 6 m and a flow rate of up to 25.20 m³/h, with a maximum input power P1 of 260 W. With an energy efficiency index EEI ≤ 0.21, 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 environment. The motor does not require external protection: the electronics protects it against overload, overheating, phase failure, 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, free of solid particles and mineral oils, with a glycol content of up to 30 % and a temperature from −10 to +110 °C; the ambient temperature must be up to 40 °C. The maximum operating pressure is 16 bar and at least 10 m w.c. must be maintained on the suction side at 90 °C, or 20 m w.c. at 110 °C. Flanges DN 50 PN 10 are not part of the packaging, they are supplied on request. The cast iron version is not suitable 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 60/240.50 M mean?
B denotes a simple flanged version, 60 is the maximum delivery head in decimetres (6 m), 240 is the construction length in millimetres and 50 is the nominal flange DN 50. The letter M means a single-phase motor 220–240 V.

Are the flanges part of the packaging?
No, flanges DN 50 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 60/240.50 M as equivalent to Grundfos MAGNA 50-60 F, MAGNA 1 50-60 F, MAGNA 3 50-60 F and UPS 50-60/2 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.
