About Pump BEST ONE-VOX
AISI 304 stainless steel submersible pump with mechanical seal made of Ceramic/Carbon/NBR and oversized oil chamber. Possibility of fixed or mobile installation and suitable for domestic applications and large industrial drainage installations
Features
- Sturdy design, corrosion resistant
- Possibility to use in fixed and mobile installations
- Practical and easy to use
description Pump BEST ONE-VOX
AISI 304 stainless steel submersible pump with mechanical seal in Ceramic/Carbon/NBR and oversized oil chamber that increase the life and reliability.
BEST ONE has a semi-open impeller, while BEST ONE VOX is equipped with vortex type impeller, to ensure a greater free passage and reduce the possibility of clogging.
The electric pumps offer 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 1.8 to 8.3 m for
BEST ONE and from 1.5 to 6 m for
BEST ONE VOX - Capacity from 1.2 to 10.2 m3/h
- Maximum immersion 5 m
- Maximum liquid temperature 50°C
- Maximum solid size passage:
– 10 mm
– 20 mm for version VOX (VORTEX)
INSTALLATION
The BEST ONE electric pumps have a wide versatility of installation. The possibility of choosing between the vertical magnetic float (small) or the float switch allows choosing of the best option also based on the space available to insert the pump. Furthermore, the choice of switch type also depends on the water level for which pump start is preferred.
Submersible electric pump for clear water with AISI 304 stainless steel hydraulics. Outer casing, impeller, filter, motor cover, seal holder disc and motor case all in AISI 304, shaft in AISI 303. The mechanical seal is standard in Ceramic/Carbon/NBR.
Provided with 5 m of power cable type H05 RN – F (single phase), H07 RN – F (three phase) for internal use, with or without float.
