5 Threaded horizontal multistage centrifugal electric pumps HM-HMZ-HMS -HMS Series MARKET SECTORS INDUSTRIAL, CIVIL, AGRICULTURAL. APPLICATIONS Pumping of water for domestic (HM) and industrial use (HMS). Special version (HMZ) particularly suitable for critical application in suction. Small irrigation systems. The HMS series pump can handle water (containing additives) having moderate chemical aggressiveness, but free of suspended solids. Composition of pressure booster units for various purposes. Pumping of liquids compatible with AISI 316L stainless steel (DIN 1.444) for HMS version. Liquid end made entirely of stainless steel for HMS Silent operation High performance and reliability Standard supplied IE2 motors are compliant with Regulation (EC) no. 64/29. SPECIFICATIONS PUMP Delivery: 2HM-4HM: up to 12 l/min (7,2 m 3 /h). 2HMS-4HMS: up to 12 l/min (7,2 m 3 /h). Head: 2HM-4HM: up to 6,7 m. 2HMS-4HMS: up to 51,2 m. Maximum operating pressure: 8 bar (PN 8). Continuous duty. Temperature of pumped liquid: -1 C to +6 C for HM-HMZ. -1 C to +11 C for HMS. MOTOR Asynchronous, squirrel cage rotor, close construction, external ventilation. Protection class: IP55. Class 155 (F) Insulation. Performances to EN specifications. Standard voltage: - Single-phase versions: V 5 Hz, 2 poles, with automatic reset overload protection. - Three-phase versions: 22-24/ V 5 Hz, 2 poles, the overload protection must be provided and installed by the user. 5

25 NPSH 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. 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. 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). 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. To find the static height hz at which to install the machine under safe conditions, the following formula must be verified: hp + hz (NPSHr +.5) + hf + hpv 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.,5 is the safety factor. 1 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. 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. Water temperature ( C) Suction loss (m),2,7 2, 5, 7,4 15,4 21,5 Elevation above sea level (m) Suction loss (m),55 1,1 1,65 2,2 2,75 3,3 Friction loss is shown in the tables at pages 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. Make the following calculation: Liquid: water at ~15 C γ = 1 kg/dm 3 Flow rate required: 3 m 3 /h Head for required delivery: 43 m. Suction lift: 3,5 m. The selection is an FHE 4-2/75 pump whose NPSH required value is, at 3 m 3 /h, di 2,5 m. For water at 15 C hp = Pa / γ = 1,33m, hpv = Pv / γ =,174m (,171 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: 1,33 + (-3,5) (2,5 +,5) + 1,2 +,17 from which we have: 6,8 > 4,4 The relation is therefore verified. 25 TECHNICAL APPENDIX
