Description of NOWA LCA 25-4-180B Circulation Pump
The NOWA LCA 25-4-180B circulation pump is designed for forced circulation of working fluids (heat carriers) in closed and open heating and air conditioning systems.
By design, the NOWA LCA 25-4-180B circulation pump is equipped with a mechanism that converts flow energy into pressure and delivers water in the desired direction. The pump connects to a single-phase AC network with a voltage of 230 V and a frequency of 50 Hz, and is installed in a mounted heating system. The heat carrier temperature can vary widely – from +2°C to +110°C.
Permitted heat carrier substances:
- purified water;
- antifreezes based on ethylene glycol and propylene glycol;
- fire-safe, mineral, and synthetic oils.
The circulation pump is not intended for pumping hard fresh, mineral, and sea water, aggressive and flammable liquids and solutions, food products, highly viscous liquids, and emulsions. The water pumped by the pump must not contain large abrasive or solid inclusions.
Operating conditions:
- the viscosity of the liquid used must not exceed the viscosity of water by more than 20%;
- operating temperature range of circulating water – from +2°C to +110°C;
- ambient temperature from +4°C to +40°C and humidity not exceeding 95%;
- maximum system pressure can reach 10 bar;
- the hydrogen index (pH) of the heat carrier must be within 6.5–8.5 units.
