The H1 series universal electric motor (pump head) is a classic and time-tested three-speed motor that is used in all types of pumps with counterclockwise rotor rotation. Also, such electric motors are used in wall-mounted gas boilers, which were installed in the UK until the autumn of 2015. Electric motor rotor speed control is quite simple - with a standard three-position switch. The H1 Series electric motor is designed to replace failed pump motors in almost the majority of combi boilers installed in UK households before 2015.

In most cases, engineers servicing wall-mounted boilers recommend their clients do not completely change the pump that has failed, but only change the pump electric motor to restore the boiler operation. And this has become common practice in the UK in recent years. This is done not only to reduce the cost of failed pump repair. The cost of a universal electric motor of the H1 series is several times cheaper than a complete pump assembly for a wall-mounted boiler. But thanks to the simplicity of the process itself, the time to replace the universal electric motor of the H1 pump is several times less than the time to replace the entire pump in the boiler. Electrical contacts when installing an electric motor, are connected in the terminal box very quickly using spring clamps. The electric motor installation takes no more than 10-15 minutes, taking into account the removal of the old failed motor by unscrewing four bolts, disconnecting it from the electrical network and completely installation of a new H1 Series motor.

To make the right choice, you need to know exactly the direction of rotation of the failed pump motor in your boiler. This is easy to see by looking on the nameplate of your pump in the boiler. If you see an arrow pointing counterclockwise, you need to select our H1 series model. If the arrow direction on the nameplate is clockwise, you need our model of electric motors of the H2 series. You should also know the pressure of your electric motor in the boiler, which varies in meters. To make the right choice, look to the nameplate - the head is usually indicated in meters and corresponds to the numbers 4, 5, 6, 7 or 8 meters. In our catalogue you can find a model similar to the specifications of your boiler pump, and you could save at least £100 from your household budget if you take our advice. Also, if you want to find a replacement motor for your circulation pump, which is located somewhere in the garage or basement, we recommend you to take some measurements using a ruler or tape so that you know which motor you need. You need to know the distance between the row and diagonally located engine mounting bolts. After this, you can look and compare on our website the same overall dimensions on our universal electric motors and make a decision on your choice or further search.

H1 Series electric motors do not require maintenance during the entire service life that confirms their high reliability, which is why we successfully offer our customers a 6-year warranty for this equipment.

FEATURES

Three fixed pump speeds are manually selected using a mechanical switch, allowing to use the entire pump power range.
The screw that unlocks the pump rotor will allow to easily restore its operation after many months of inactivity.
Very low noise level during pump operation.
Very easy installation of the electric motor using a set of universal bolts that are supplied complete with the electric motor.
Very simple connection of the pump to the electrical network in the boiler, using spring-loaded electrical clamps in a terminal box of the pump.

MATERIALS

The electric motor casing, in which all its electrical parts are hidden, is aluminium and ventilated, that eliminates internal condensation and corrosion.
The plastic box with electrical contacts allows easy access and is sealed according to industry standard IP44.
The pump rotor is located directly in the pumped fluid, which ensures its cooling and lubrication, and this is one of the factors of high reliability and extended life cycle of our pumps.
The impeller is made of PES Series composite material, capable of withstanding high temperature and mechanical overloads, which guarantees a long service life, without replacement throughout the entire life cycle of the pump.
Each electric motor is tested in production at a pressure of 10 bar and this is a guarantee of perfect tightness and safe operation in closed heating systems, thanks to the special casing shape, the highest fit quality of all internal and external elements of the pump, as well as reliable rubber rings.
All our electric motors have Class F Insulation because we use the highest quality materials, capable of operating at ambient temperatures up to +40°C and the pump casing temperature limit up to +155°C.
The electric motor is supplied in a reliable cardboard box, with a set of universal bolts designed for fastening to the cast iron casing of the boiler pump, high-temperature rubber gasket, data sheet and warranty instructions.
