Applications And Use - FLOWTECH flowboost K.H Operation And Maintenance Manual

Motor energy efficient information
All electric pumps use motors compliant with reg. 640/2009 EC and subsequent amendments, therefore,
compliant with efficiency class IE3 (three-phase versions with power greater than 0.55 kW).

Applications and use

These appliances are designed for professional use in applications such as water supply from groundwater,
pressure increase, irrigation or heat transfer fluid circulation. They can be used in the industrial, manufacturing
or equivalent fields. The electric pumps can also be used in the domestic, commercial, agricultural, artisan or
tertiary sectors, for the same applications.
Electric pumps must be installed in dry areas and protected from flooding.
The electric pump can work continuously at the maximum room temperature indicated on the rating plate.
Pumped liquids
Clean liquids, compatible with the electric pump component materials. A liquid must have physical
characteristics similar to those of clean water at room temperature (1030 kg/m3 maximum density and 2 cPs
maximum viscosity. If these limits are exceeded, contact the manufacturer).
Improper use can result in overheating of the machine and power cables, with consequences such as failure
and potentially fire.
Conditions of use
Maximum operating pressure (pump delivery pressure, obtained by the sum of the pump inlet pressure and
the pressure increase supplied by the pump): see the rating plate. The maximum pressure at the appliance
inlet is determined by the pressure increase created by the pump, so as not to exceed the maximum
operating pressure (see the section dedicated to the calculation).
Flow rate and head: during normal operation, they must fall within the fields indicated on the rating plate.
Under these conditions, optimal machine operation is achieved.
Sucked liquid maximum temperature: 35 °C, 55 °C, 85 °C or 110 °C depending on use (see paragraph 3.1).
Sucked liquid minimum temperature: -10°C (EPDM gaskets); -10°C (Viton®/ FKM gaskets); 0 °C (self-priming
models).
Room temperature: maximum 40 °C up to 1000 m altitude. If these limits are exceeded, contact the
manufacturer.
Electrical supply voltage: refer to the motor rating plate. The maximum deviation allowed is +/- 6% of the
nominal value.
Maximum number of consecutive hourly start-ups: 40.
Non-permitted use
• Do not use the electric pump for applications other than those described above and, in any case, not
authorised by the manufacturer. Improper use may cause serious damage (including death) to people,
animals, objects and the environment.
• Do not use the electric pump connected to swimming pools, basins, ponds and in similar places when
people are in the water.
• Do not pump food liquids or human food products.
• Do not pump any liquids that are more viscous and/or denser than water.
• Do not use the machine in potentially explosive environments or with flammable liquids.
• Do not run the machine without any liquid.
To avoid overheating, do not run the electric pump continuously at a flow rate of zero or lower than 10% of
the rated value. If the temperature of the inlet liquid exceeds 90 °C, increase the minimum flow rate to 20% of
the nominal value.
Do not exceed the maximum pressure indicated on the rating plate.
