description Pump SB3

3” submerged well pump with outer casing in AISI 304 stainless steel and impellers in glass fibre reinforced PPO.
It can be coupled with motors in water bath or oil bath.
It is quiet, especially sturdy and efficient, but above all versatile, also suitable for horizontal operation.

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)
The NPSH curve is an average curve obtained in the same conditions of performance curves.
The continuous curves indicate the recommended working range. The dotted curve is only a guide.
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
P2 = pump power input (shaft power)
 = pump efficiency

SB3, the smallest with a diameter of 3”, combines the advantages of the AISI 304 stainless steel components with the advantages of technopolymer hydraulics, followed by 4” WINNER 4N, 4WN and 4BHS. The WINNER 4N and the 4WN have stainless steel components and technopolymer impellers while the 4BHS is made entirely of stainless steel. The range also includes IDROGO, 5” electric pump. It has an external casing, filter and closing ring in AISI 304 stainless steel, while the impeller and diffuser are in polypropylene and polystyrene (PPE + PS). Then there are SF6 and 6BHE
which are 6” electric pumps. The first has a stainless steel outer casing and PPO impellers reinforced with glass fibres, the second is entirely in AISI 304 stainless steel and is also available in AISI 316 (6BHEL).
The product series is completed by the 8BHE, an 8” submersible electric pump, also completely in AISI 304 stainless steel and also in the AISI 316 (8BHEL) version

Technical
