Description
Centrifugal borehole pump 0.25kW H 42 (36) m Q 55 (30) l/min Ø102mm (30m cable) AQUATICA (DONGYIN) 4SEm2/6 (777442)
Pumps of this series are designed for pumping clean water and can be used for: domestic water supply from boreholes and reservoirs (cooling shroud installation is mandatory), pumping water into tanks, irrigation systems, and automatic water supply in conjunction with small tanks when using a pressure switch.
The pump's electric motor is connected by a cable:
- Brand H07RN-F (analog of KG-KhL)
- Copper wire cores, sheath - polyethylene terephthalate film and insulating rubber
- Flexibility – multi-wire conductive cores combined with a small twisting pitch
- Ambient air temperature from -25°C to +60°C
- Cable insulation withstands a temperature of +200°C during a short circuit lasting no more than 5 seconds
- Cross-section is calculated and corresponds to the motor power
