Technical data

6.1 Sound pressure and sound effect level for W+ Pumps
Measurements have been carried out in accordance with ISO 3743,
Grade 2, and ISO 3746, Grade 3. Tolerance: +3 dB.
"LpA in dB" refers to the sound pressure level at a distance of one
metre from the surface of the pump at a height of 1.6 m above floor
level (cf. EC Directive (89/392/EEC) 1.7.4.).
Operating conditions A, B and C are defined as follows:
A. Nominal flow and operating pressure
B. Nominal flow and 60% operating pressure
C. 60% flow and operating pressure
The nominal flow and max. operating pressure in the case of the
W+ 55/60, for example, are 60m³/hr at an operating pressure of 55WG,
and so on.
This information only applies if the motor used is an ABB light alloy
motor and the size of the motor matches the power requirement of the
pump.
The values shown apply when the pumps run at 2900 rpm and have a
shroud over the motor. The values for the W+ 25/210 apply at 1450
rpm. If the pumps are run at 1450 rpm, the values are reduced by
about 20 dB.

6.2 Maximum permissible outlet pressure for W+ Pumps
The maximum pump outlet pressures specified below must not be
exceeded (applies to water at 20°C).
Max. 20 bar: W+ 110/130 (16 screws)
Max. 18 bar: W+ 10/8, W+ 22/20, W+ 30/80, W+ 35/55, W+ 35/35
Max. 14 bar: W+ 25/210, W+ 30/120, W+ 50/8, W+55/35, W+ 55/60,
W+ 60/110, W+ 65/350, W+ 70/40, W+ 80/80, W+ 110/130
The above values also apply to the corresponding models in the
Wa+ and Wi+ versions.
