PERFORMANCE CURVE SPECIFICATIONS
The specifications below qualify the curves shown on the following pages.
Tolerances according to ISO 9906 Annex A
The curves refer to effective speed of asynchronous motors at 50 Hz
Measurements were carried out with clean water at 20°C of temperature and with a kinematic viscosity
of = 1 mm2/s (1 cSt)
In order to avoid the risk of over-heating, the pumps should not be used at a flow rate below 10% of best
efficiency point.
Symbols explanation:
Q = volume flow rate
H = total head
Submersible electric pumps for waste water in AISI 304
Submersible electric pumps in stainless steel AISI 304 for waste water. They have a pump body,
impeller, motor cover, seal holder disc and motor case in AISI 304, while the shaft is in AISI 303.
Double mechanical seal with interposed oil chamber: the upper one in carbon/ceramic/NBR (motor
side), the lower one in SiC/SiC/NBR (pump side).
G20 cast iron spacer (only for DW – DW VOX 300).
Available single-phase versions with or without float.
Special Versions
– Single-channel impeller version (DW)
– Vortex type impeller version (DW VOX)
– Flanged version (DWF/DW VOXF)
INSTALLATION
The DW – DW VOX electric pumps are also available with a float switch, thus increasing the versatility of use. The choice of the use of the float switch requires the respecting of minimum installation spaces to guarantee correct operation of the pump itsel
