Item NO.:
Basic 25-20SZRadiator heating systems
Underfloor heating
Hot water circulation in apartments and houses
Solar water heating systems (low-temperature circulation)
Booster circulation in villa and rural housing
Three-Speed Control
Easily adjustable flow for different heating needs, helping reduce power consumption during mild weather.
Low Noise&No Leakage
Quiet operation and a sealed rotor design ensure comfortable, leak-free use in residential environments.
Wide Temperature Range
Handles liquid temperatures from 2°C to 110°C – ideal for cold winter nights and year-round hot water circulation.
Durable & Corrosion Resistant
Built with robust materials including stainless steel and silicon carbide, ensuring long life even in challenging water quality conditions.
Easy to Install & Maintain
Horizontal design with threaded connections makes installation simple, and the self-lubricating motor requires no regular maintenance.
1.Material Options for Different Applications
Cast Iron Housing: Recommended for clean water circulation in general heating systems.
Brass/Bronze Housing: Ideal for underground pipe heating applications, offering enhanced corrosion resistance.
Stainless Steel or Brass/Bronze Housing: Recommended for domestic hot water circulation to ensure hygiene and durability.
2. Ambient temperature: 0℃~40℃，temperature of medium: 2℃ ~110 ℃. In order to avoid condensed water in stator, make sure the ambient temperature is lower than liquid temperature.
3. Medium: thin, clean, non-corrosive and non-explosive liquid, does not contain any solid particles, fibers or mineral oil. Pump must not be used for delivering flammable liquids, such as diesel and gasoline. Delivering liquid of high viscosity will reduce performance of the pump, so while choosing a pump, the viscosity of the medium must be taken into consideration.
4. Maintain minimum pressure at the pump inlet to avoid cavitation noise and damage to pump bearings.
