- Possibility to use in fixed and mobile installations
- Practical and easy to use
description Pump OPTIMA
AISI 304 stainless steel submersible pump with mechanical seal in oil bath and oversized oil chamber. These features make the pump reliable, durable and corrosion-resistant.
The OPTIMA electric pump has a great versatility of installation (fixed or mobile) due to the possibility of choosing between the vertical magnetic float switch (of reduced size) or the float switch.
These solutions also allow you to choose the best pump insertion option according to the space available.

PERFORMANCE CURVE SPECIFICATIONS
The specifications below qualify the curves shown on the following pages.
Tolerances according to ISO 9906:2012 – Grade 3B
The curves refer to effective speed of asynchronous motors at 50 Hz, 2 poles.
Measurements were carried out with clean water at 20°C of temperature and with a kinematic viscosity
of ν = 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
Technical
- Total head from 1.5 to 7.6 m
- Capacity from 1.2 to 9 m3/h
