渦流ポンプ Rexa UNI series

復水水電動

Product
For the sewage disposal of small commercially used buildings. The Wilo-Rexa UNI is suitable as an entry level model for smaller commercial buildings for sewage disposal (according to EN 12050-1). The pump can be used portable or in the pump chamber as a system solution. Vortex hydraulics with corrosion-resistant composite and smooth surface provide high reliability and universal applicability.

Advantages / Key benefits

• Excellent reliability due to corrosion-free hydraulics for universal application and various fluids
• Light weight; integrated capacitor in the single-phase AC motor and flange with integrated fixation for easy installation
• Vortex hydraulics and smooth surfaces for optimum efficiency and operational reliability
• Quick maintenance facilitated by direct access to the sealing chamber and pump housing
• Longer maintenance intervals due to double seals and a large sealing chamber

Product features

• Vortex hydraulics made of corrosion-free copolymer
• Motor housing made of stainless steel (available in different qualities)
• Single-phase AC motor with integrated capacitor
• Combination flange with integrated and captive fixation and flat gasket
• Hydraulics housing with integrated pump support foot
• Direct access to sealing chamber and hydraulics

Design
Submersible pump for stationary and portable wet installation in intermittent operation.

Liquids / Applications

• Sewage pumping according to EN 12050-1 (suitable for sewage disposal in small commercial buildings)

Equipment / Functions

• Thermal motor monitoring with bimetallic sensor
• Single-phase AC motor with self-switching thermal motor monitoring
• Single-phase AC motor with integrated condenser
• Versions: P = with plug; A = with float switch and plug; O = bare cable ends

Type key (explanation of model code)
Example: Wilo-Rexa UNI-V05B/21T006-540/O
Rexa = Submersible sewage pump
UNI = Series
V = Vortex impeller
05 = Nominal diameter of discharge port (05 = DN 50; 06 = DN 50/65)
B = Version (A = standard version, B = V4A version, K = V4A + cooling jacket)
2 = Number of poles
1 = IE-efficiency class (derived from IEC 60034-30)
T = Mains connection version (M = 1~, T = 3~)
006 = Rated power (e.g. 006 = 0.37/0.55/0.75... represented as P in kW)
5 = Mains connection frequency (5 = 50 Hz, 6 = 60 Hz)
40 = Key for rated voltage
O = Additional electrical equipment (P = with plug, A = with float switch and plug, O = bare cable end)
