About Pump WINNER 4N

4″ submerged sump pump with floating impellers with front shim, suitable for handling water in general and also for horizontal operation

Features

  • Silent
  • Practical and easy to use
  • Suitable for horizontal operation

description Pump WINNER 4N

4″ submerged sump pump equipped with a special system of floating impellers with front shim, which allows it to operate even in particularly heavy conditions without blocking and which gives the electric pump a low axial load.
It is a very quiet product that boasts high hydraulic efficiency that can be coupled with motors in water bath or oil bath.
It can also be used in a horizontal position.

4” submersible centrifugal pump

4” submersible centrifugal electric pump in AISI 304 with floating impellers with frontal shim.
Outer casing, shaft and valve are in AISI 304. Discharge casing in EN 1.4308 (ASTM CF8). The impeller is in Ixef® (glass fibre reinforced thermoplastic) for 4N1 – 4N2 – 4N4 – 4N7 models, in glass fibre reinforced polycarbonate for 4N10 – 4N15 models, PPE+PS diffuser reinforced with glass fibres. Particularly recommended for the movement of clear water in wells, the pressurisation of clean water for agricultural, domestic or industrial use, or for the irrigation and movement of water in general

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 ν = 1 mm2/s (1 cSt)
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)
η = pump efficiency
NPSH = net positive suction head required by the pump
MEI = minimum efficiency index

The minimun efficiency index (MEI) is a measure of the quality of a pump size in respect to its mean efficiency. The minimum efficiency index is based on the hydraulic efficiency and on the head at the best efficiency point.
The efficiency of a pump with trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter.
The operation of these water pumps with variabile duty points may be more efficient end economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system.
