Circulation Pump Series
LRS series of circulating pump researched and developed by scientific research personnel of our company has following merits: no leakage, low noise, environmental protection, beautiful appearance, convenient installation, run responsible and so on, t is designed special for heating system and it can be used to supply water and add pressure for mansions of city, villa of suburb, house, to match with industrial equipment, to supply water in cycle for cooling air-condition, boiler and solar energy, supply hot water and keep warm in cycle, etc.
Scope of Application
Ground heating system cycle
Heating system cycle
Cooling of industrial equipment
Product Structure
1. Structure: The product is made up of pump and single-phase shield motor. The pump is made up of impeller, body of pump, etc. Motor consists of stator, rotor, shield cover, deflating bolt and so on.
2. Tightness: The pump isn't sealed with machinery sealing. The stator and rotor of motor are sealed with stainless steel cover. Other parts are all sealed with heat-resisting rubber fading ring.so that there/s no leakage.
3. Lubricate and cool: Inside circulation way is adopted in the product. The water between the stator and the rotor can lubricate and cool the motor as the lubricant and coolant.
Installation
Pump installation must ensure that the level of the motor shaft and the ground plane, at startup, motors to be located at the top of the drain plug removed so that the gas well pump discharge, avoid Pump-free state in the water to run.
