Lowara SVH SERIES ELECTRIC PUMPS WITH HYDROVAR® CONTROL SYSTEM The Lowara SV electric pumps are available in the SVH version, i.e. coupled to Hydrovar®, the microprocessor based control unit designed to manage the performance of the pump based on the conditions and requirements of the system. The basic SV electric pump is thus transformed into a complete pumping system suitable for a number of applications, including: • Variable speed pressure boosting (constant pressure is maintained in industrial, civil and agricultural applications). • Water filtration and treatment (constant flow is maintained based on flow resistance). • Air conditioning and heating (constant differential pressure is maintained in a closed circuit).

• No special pumps or motors: HYDROVAR® is mounted directly onto a standard three-phase TEFC motor with class F insulation up to 22 kW power. A wall-mounted version is available for higher powers, up to 45 kW.

• No extra pressure sensors: HYDROVAR® is equipped with a pressure transmitter or differential pressure transmitter, depending on the applications.

• No separate microprocessors: In multiple-pump systems the microprocessor regulates the sequential operation of the pumps or motors. Since HYDROVAR® features a built-in microprocessor, no other control devices are required.

• No separate control panels or converters: HYDROVAR® performs all the functions of a pump control panel, incorporating protections against overload, short circuit, high temperature, etc. The only external device required is a fuse on the power supply line. Will depend upon any local electrical installation regulations.

With the HYDROVAR® system the speed of each pump varies in order to maintain a constant pressure or flow. A small tank is sufficient to maintain system pressure and to ensure immediate shut off at zero demand, therefore there is no need to install a large tank. Where local regulations allow it, the HYDROVAR® systems can be connected directly to the water supply line. The pump’s operation at the correct speed based on system requirements enables energy consumption to be substantially reduced.

• Anti-condensation heater

• No by-pass lines or safety systems:

All the units are equipped with anti-condensation heaters that switch on when the pump is in standby mode to prevent condensation inside the unit.

With HYDROVAR® the pump switches off immediately when demand is zero or exceeds the maximum capacity of the pump. This way there is no need to install additional safety devices.

• No large diaphragm tanks are required: Without a large pressure tank on the discharge side of the pump, a constant speed pump running at maximum power will be constantly switching on and off in order to satisfy system demands.

18


Lowara OPERATING PRINCIPLE The basic function of the HYDROVAR® device is to control the pump to meet the system demands. HYDROVAR® performs these functions by: 1) Measuring the system pressure or flow via a transmitter mounted on the pump’s delivery side. 2) Calculating the motor speed to maintain the correct flow or pressure. 3) Sending out a signal to the pump to start the motor, increase speed, decrease speed or stop. 4) In the case of multiple pump installations, HYDROVAR® will automatically provide for the cyclic changeover of the pumps’ starting sequence.

Control for constant pressure

In addition to these basic functions, HYDROVAR® can do things only by the most advanced computerised control systems, such as: • Stop the pump(s) at zero demand. • Stop the pump(s) in case of water failure on the suction side (protection against dry running). • Stop the pump if the required delivery exceeds the pump’s capacity (protection against cavitation caused by excessive demand), or automatically switch on the next pump in a multiple series. • Protect the pump and motor from overvoltage, undervoltage, overload and earth fault. • Vary the pump speed acceleration and deceleration time. • Compensate for increased flow resistance at high flow rates. • Conduct automatic test starts at set intervals. • Monitor the converter and motor operating hours. • Display all functions on an LCD in different languages (Italian, English, French, German, Spanish, Portuguese, Dutch). • Send a signal to a remote control system which is proportional to the pressure and frequency. • Communicate with another HYDROVAR® or control system via an RS 485 interface.

Lowara NPSH The maximum possible suction head for installation depends on the value of the atmospheric pressure (i.e. the elevation above sea level at which the pump is installed) and the temperature of the liquid.

The minimum operating values that can be reached at the pump suction end are limited by the onset of cavitation. Cavitation is the formation of vapour-filled cavities within liquids where the pressure is locally reduced to a critical value, or where the local pressure is equal to, or just below the vapour pressure of the liquid.

To help the user, with reference to water temperature (4° C) and to the elevation above sea level, the following tables show the drop in hydraulic pressure head in relation to the elevation above sea level, and the suction loss in relation to temperature.

The vapour-filled cavities flow with the current and when they reach a higher pressure area the vapour contained in the cavities condenses. The cavities collide, generating pressure waves that are transmitted to the walls. These, being subjected to stress cycles, gradually become deformed and yield due to fatigue. This phenomenon, characterized by a metallic noise produced by the hammering on the pipe walls, is called incipient cavitation.

Water temperature (°C) 20 Suction loss (m)

The damage caused by cavitation may be magnified by electrochemical corrosion and a local rise in temperature due to the plastic deformation of the walls. The materials that offer the highest resistance to heat and corrosion are alloy steels, especially austenitic steel. The conditions that trigger cavitation may be assessed by calculating the total net suction head, referred to in technical literature with the acronym NPSH (Net Positive Suction Head).

Make the following calculation:

To find the static height hz at which to install the machine under safe conditions, the following formula must be verified:

Liquid: water at ~15°C γ = 1 kg/dm3 Flow rate required: 30 m3/h Head for required delivery: 43 m. Suction lift: 3,5 m. The selection is an FHE 40-200/75 pump whose NPSH required value is, at 30 m3/h, di 2,5 m.

where: hp is the absolute pressure applied to the free liquid surface in the suction tank, expressed in m. of liquid; hp is the quotient between the barometric pressure and the specific weight of the liquid. hz is the suction lift between the pump axis and the free liquid surface in the suction tank, expressed in m.; hz is negative when the liquid level is lower than the pump axis. hf is the flow resistance in the suction line and its accessories, such as: fittings, foot valve, gate valve, elbows, etc. hpv is the vapour pressure of the liquid at the operating temperature, expressed in m. of liquid. hpv is the quotient between the Pv vapour pressure and the liquid’s specific weight. 0,5 is the safety factor.

Friction loss is shown in the tables at pages 48-49 of this catalogue. To reduce it to a minimum, especially in cases of high suction head (over 4-5 m.) or within the operating limits with high flow rates, we recommend using a suction line having a larger diameter than that of the pump’s suction port. It is always a good idea to position the pump as close as possible to the liquid to be pumped.

The NPSH represents the total energy (expressed in m.) of the liquid measured at suction under conditions of incipient cavitation, excluding the vapour pressure (expressed in m.) that the liquid has at the pump inlet.

hp + hz ≥ (NPSHr + 0.5) + hf + hpv

40

For water at 15 °C hp = Pa / γ = 10,33m, hpv = Pv / γ = 0,174m (0,01701 bar) The Hf flow resistance in the suction line with foot valves is ~ 1,2 m. By substituting the parameters in formula 1 with the numeric values above, we have: 10,33 + (-3,5) ≥ (2,5 + 0,5) + 1,2 + 0,17 from which we have: 6,8 > 4,4 The relation is therefore verified.

The table is valid for the Hazen Williams coefficient C = 100 (cast iron pipework). For steel pipework, multiply the values by 1.41. For stainless steel, copper and coated cast iron pipework, multiply the values by 1.85. When the equivalent pipeline length has been determined, the flow resistance is obtained from the table of flow resistance. The values given are guideline values which are bound to vary slightly according to the model, especially for gate valves and non-return valves, for which it is a good idea to check the values supplied by the manufacturers.
