Introduction to HR AC/DC submersible pumps

HR AC/DC is a 4” submersible pump for clean water applications:

Three phase permanent magnet motor with wet rotor and canned type resin filled stator.
Built-in inverter on board.
Helical rotor pump.

Pump inverter allows the following:

Modified pump speeds that allow the pump to run at its highest efficiency point based on the power available.
Soft start and soft stop to increase the system life and reduce the current peaks.
Protects the motor from overload, dry running, overvoltage, under voltage and possible abnormal conditions.

HR AC/DC pumps can be used in residential and industrial applications with pressurized water systems that create:

Energy savings.
Simple and quick installations.
Long life and reliability.

HR AC/DC pumps can be fed both AC and DC power with a wide range of operating voltages (90- 265 VAC or 90-400 VDC).

This means that the same pump can be powered by photovoltaic panels, wind, generator or batteries. The hydraulic performance will be adjusted automatically according to the power source and the power available.

With photovoltaic panels, an MPPT algorithm is used to maximize the pump’s output based on available sunlight.

Pump speeds are adjusted in relation to solar irradiation. When solar irradiation increases, the pump will run faster and pump more water. When solar irradiation decreases (clouds moving and/or different hours of the day,) the pump will reduce its frequency and slow down, but it will continue pumping until the solar irradiation reaches the minimum value necessary to keep pumping.

HR AC/DC pumps can be installed with or without the Control Module controller (CM MP). The controller records the following:

Run time.
Input voltage, current and power.
Alarms: dry running, overload, overvoltage.

Digital inputs make it possible to connect a float switch, a pressure switch, start and stop signal, etc…
Running and alarm status are given by two digital outputs.
Analog inputs can be used to connect sensors (i.e. flow meter).

Safety Instructions

Sun Pumps strongly suggests to carefully read this operation manual before using and installing its products.

Any operation (installation, maintenance and repair) must be carried out by trained, skilled and qualified personnel. Failure to observe and follow the instructions of this manual may result in fatal electric shock.

Disconnect the unit from the power supply before any maintenance is performed.
Do not remove for any reason, the cover of the CM MP and the cable guard without having visually disconnected the unit from the power supply and having waited at least 1 minute. This allows the capacitors to bleed off their stored power.
CM MP and pump system must be grounded properly before operation.
High voltage is present even if the pump is not running.
Do not start the pump for any reason unless the pump is completely immersed in water.

Avoid shock or serious impact during transportation.
Check the product immediately upon delivery and check for damage and/or missing parts. In either case, immediately notify the supplier.
Damages due to transportation, incorrect installation, or improper use of the device will null and void the warranty. The manufacturer cannot be held responsible for any damage to people and/or property due to improper use of its products.

CM MP installation

Remove the special inserts, shown below.
Use two screws inserted through the holes underneath the inserts to mount the CM MP in a vertical position.
CM MP installation

Then replace the special inserts so the cover can be attached.
The IP55 protection rating allows the CM MP to be installed in humid and dusty environments.
However it is recommended to protect the CM MP from the direct exposure to weather and sunlight.

Carefully read the safety guidelines before installing the device.
At the end of the installation, make sure no other objects are inside the CM MP or deposited on the electronic board. Tighten all 4 screws with the washers on the cover before powering up the device. Failure to properly ground the controller may result in electric shock or even death.
