Mega automatic circulator pump is the ideal choice for almost any building project – old or new. With its unrivalled energy efficiency, all-encompassing range and built-in communication capabilities.
Mega is ideal for engineers and specifiers looking to create high-performance heating and cooling systems.
The pump is maintenance-free due to the canned-rotor type design. This also means that pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. MEGA features PWM and 0-10V external control.
Construction
Mega pumps are wet rotor pumps, i.e. the pump and the motor are a single-piece unit without shaft end seal. The bearings are lubricated with pumped liquid.
The pumps feature:
• controller built in a control unit;
• operating panel at the front of the pump;
• external protection of the motor is not required.
Motor and frequency converter
Mega pumps are equipped with permanent-magnet motor. This motor type is characterized by an increased efficiency in comparison with traditionally used asynchronous squirrel-cage motors. Motor speed is set up by a built-in frequency converter.
Pump connections
Threaded pipe and flange connections.
Surface finish quality
A pump housing and its head part have cataphoretic coating for better corrosion resistance.
Cataphoretic coating application includes the following steps:
• alkali cleaning;
• zinc phosphate pre-treatment;
• cathodic electrodeposition (cataphoresis);
• varnish-and-paint film drying at 200 °C–250 °C.
Easy installation and operation
Equipped with Self Adapting Mode(Auto Mode, Factory Setting), pump runs once the power is connected and adapts its performance according to actual system needs.
Control is effected by digital pulse-width modulation (PWM) low-voltage signal, enabling pump to be used to meet different flow requirement in various systems.
Low noise and high comfort
Noise index: ≤42dB(A)
Low energy consumption
A class energy efficiency, Power consumption lowest to 6W
Multiple protection
With over-voltage and over-current protection
Eco-Design Benchmark
EEI≤0.23-Part 2
Quick release power plug
Start-up and stop the pump quickly.

Pumped liquids
The pump is designed to pump pure and nonaggressive liquids without solids or fibers that can have a mechanical or chemical impact on the pump.
Water used in heating systems should meet the quality requirements of system water for heating units.
The pumps must not be used for inflammable or explosive liquids such as diesel fuel or petrol.
The pumps must not be used for aggressive liquids such as acids or sea water. If the pump is not operated during a cold season, take the necessary measures to avoid low temperature damages.
Using additives in a heat transfer medium with the density and/or kinetic viscosity higher than the water ones decreases the performance of the pump.
Never use the additives that can negatively affect the pump operation. In order to learn whether the pump can be used with a certain liquid, take into account several factors.
The most important are lime content, pH, temperature, and the content of solvents and oils.
The pump can be used for glycol and water mixtures at the level up to 50 %. See section «General instructions». Pumping of glycol mixtures decreases hydraulic properties of the pump.
