Interpump IPG W 5015 (1450 об/мин) Инструкция по эксплуатации онлайн [12/76] 610062

min. 0.20 m (0.02 bars) and max. 80 m (8 bar) measured at the pump feed inlet; this minimum value

is valid for cold water having a temperature of up to 20°C, for higher temperatures, see the graph on

the last page.

The pumps can also work at a lower supply pressure, under certain operating conditions authorised by

Interpump Group Technical Department.

3.3 - It must be completely airtight and designed in such a way that its seal is guaranteed to last in

time.

3.4 - It must be equipped with a  lter of a suitable size, according to the capacity of the pump, and with

a  ltering degree of min. 300 μm; the  lter must be positioned as close as possible to the pump feed

attachment.

N.B. Even if the water to be used is clean, the  lter must be installed to prevent foreign bodies present

in the plant such as swarf, welding slag or limestone scaling from entering the pump.

3.5 - Flexible piping should be used in the section closest to the pump so as to prevent forced

connections and the transmission of vibrations.

3.6 - It must be designed in such a way as to avoid the pump emptying even only partially when it

comes to a halt.

4 - DELIVERY LINE

The following rules should be respected in designing the DELIVERY line:

4.1 - The inside diameter of the piping must be correctly sized according to the maximum pressure and

capacity so as to ensure the appropriate speed of the  uid and to limit head losses.

4.2 - The  rst section of piping connected to the pump must be  exible, so as to avoid forced connections

and to isolate the vibrations produced by the pump from the rest of the plant.

4.3 - Use should be made of pressure gauges capable of withstanding the pulsating loads typical of

piston pumps, installed in such a way as to measure the pressure directly at the pump manifold.

4.4 - In the design phase, consideration should be given to the head losses on the line, which result in

a drop in working pressure with respect to the pressure measured at the pump.

4.5 - A suitably sized pulsation damper should be installed for applications in which the pulsations

produced by the pump on the delivery line have an undesired or detrimental effect.

Use high-pressure pipes and  ttings suited to the working pressures that may arise

under all operating conditions.

Install a suitably calibrated overpressure valve, as well as the pressure regulating

valve.

5 - MAINTENANCE

5.1 - System maintenance work should be done within the time intervals laid down by the system

manufacturer, who is responsible for the entire assembly in accordance with the law.

5.2 - Correct maintenance prolongs the life of the pump and maintains its maximum performance in

time.

5.3 - All maintenance work should be done by specialized, authorized staff.

5.4 - The pump and its components are to be assembled and disassembled exclusively by authorized
