Description

RS series booster circulate pump

• Application

The pump is applicable for cold/hot water circulation and pressurization;particularly,the shower set might lead to fire because of low or unstable water pressure and installation & applicaton of this pump can easily totally solve the problem;in addition,it is also applicable for pressurization water supple of the household low water pressure,water supply of solar water heater,hot water circulation of boiler,and circulation pressurization of air conditioner & refrigerating system.

The water pump structure adopts stainless steel sleeve to completely separate the iron core inside of engine from water and it deselects the traditional mechanical seal structure so that the conventional water seal leakage problem has been thoroughly resolved;the structure adopts ceramic bearing and ceramic or stainless steel spin-dle,which is wear-resisting,corrosion-resisting,and lubricated by water naturally with lose noise;the total pump head operating voltage will not be overloaded and if it is applied appropriately,the service life should be long;high-temperature choice materials are adopted for all components inside of engine,which is applicable for hot-water circulation pressurization system;the pump can be equipped with water control automatic switch,which is convenient for usage;the pump line box is designed with three-position speed adjustment switch so that the user can regulate speed in accordance with different environments and requirements.
