Production program of the SPERONI CompanyThe production program of the SPERONI Company comprises pumps of forced circulation of hotand cold operating in heating systems.
Pumps with the rotor operating in liquidIn pumps with the rotor operating in wet conditions, the rotor is immersed in liquid andconstitutes an element of electric motor.The sleeve sealing the motor is made from high quality stainless steel and protects the stator ofthe motor against flooding by liquid. The pump shaft is made from material resistant to corrosion,featuring ceramic/graphite bearings. The pump has static sealing. Liquid forced through the pumpfulfills the following two functions: cools the pump and decreases friction in bearings.Pumps with the rotor operating in ’wet conditions operate without noise and do not requireexpenses to maintain them in the condition of technical efficiency. The group of pumps with therotor operating in ’wet conditions includes pumps with three rotational speeds, selected withthe use of U type switch as well as UE type pipes with electronic control.
Selection of proper type of pump
Selection of pump with three levels of rotational speedCharacteristic features of pumps have been presented in the form of characteristic curves, showingpressure H, power P and level of pump usage depending on flow Q.The data related to required flow and pressure drop in thesystem / installation are contained in the projectdocumentation. These data can be compared with technicalcharacteristics of pumps, shown in the form of charts; basedon it we select a proper pump.The calculated point R with coordinates Qr and Hr constitutesthe basis for selecting the pump. The pump having threelevels of speed has three characteristics Q-H, for every levelof revolutions (see Figure 1). This pump will operate in theactual working point D. This point constitutes the crossingbetween the curve of hydraulic resistance in installation andthe curve Q-H of a given pump.
Selection of electronically regulated pumpsFunctioning of electronically regulated pumps has been adjusted to the requirements regardingusage of heating energy in a year. This average usage is shown on the chart — Figure 2 — presentingthe profile of seasonal overload.

Viscosity of operational mediaAll hydraulic data and other data contained in the technical catalog, refer to operational mediain the form of water, having kinematic viscosity of 1 mm2/sec.When in individual pumps there are no separate data regarding operational medium, then inorder to receive normal functionality of the pump we have to guarantee such medium that isclean, has a standard of normal, liquid form of heating water (according to the requirements ofVDI 2035, specifying hardness and pH value of water), without aggressive and explosive additive,admixtures of mineral oil as well as hard and fibrous particles.Kinematic viscosity of water can amount to 10 mm2/sec.When viscosity of water is in the range between 1 and 10 mm2/sec, then addition of agentspreventing against freezing (e.g. glycol) has no significant influence on operation of the pump.
All rights reserved as regards changes of technical characteristics of SPERONI products withoutthe necessity of prior notification as well as errors in our technical catalog.
In regulated pumps we have at our disposal the entire operational field of a given pump, containedbetween the minimal and maximal functional curve Q-H. Therefore, this type of regulation iscalled the stepless thermal regulation. The calculation point R should be located as close as possibleto the maximal functional curve Q-H.From the figure showing the annual load, we can notice that the heating system with the fullload of thermal power, operates throughout the year only for several days. During the remainingdays the regulation system of electronic pump decreases power usage. In the case of an optimalcontrol in the system (also with the use of thermostatic valves installed on heating systems) weare able to save thanks to pumps regulating high amounts of supplied energy. These savings areshown on Figure 6.

ApplicationsThe SPERONI SCRFD circulators for clean liquids,without abrasives, which are non-aggressivefor the pump materials (contents of solids up to 0.2%).For heating, conditioning, cooling and circulation plants.For civil and industrial applications.When low noise operation is required.
Limits of application- Liquid temperature from -10 ¡C to +120 ¡C
(in short-time duty up to + 140 ¡C).- Ambient temperature up to 40 ¡C.- Maximum glycol quantity: 50%(Mixture with more than 20% glycol content
require recheking of the pumping data).- Maximum permissible working
pressure 6/10 bar.
Motor- 2/4 pole induction motor, 50 Hz.- Three adjustable speeds.- SCRFD: three-phase 230V or 400 V.- Insulation class F.- Protection IP 43.
Components- Pump casing Cast iron
- Impeller Stainless steel- Shaft Stainless steel
