water pump: GPD series single-phase pipeline screened electric pump (SUITABLE FOR SOLAR-HEATING)
CE,UL CERTIFIED The feature and use of circulating pump:
.no leakage ,Iow noise ,environmental protection ,beautiful appearance ,convenient installation, run responsible and so on;
.It 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.
;
. The products fall into GPD-S and GPD two series according to the difference in the power of motor and speed stop number. GPD-S series means three-speed one .Usually ,its rated flow is less than 5m3/h ,the input power of motor is not more than 300W.GPD series means the one-speed one .Usually ,its flow varies from 3m3/h-25m3/h and the input power of motor vary from 300W to 1300W.
;
Working condition
. Rated voltage of power supply is 220V and frequency is 50Hz single-phase AC
;
.Pressure of system < 1.0MPa;
.Pressure of water inlet > 0.1 MPa;
.Transmitted liquid shouldn't include solid impurity thevolum of which ratio exceeds O.1% or the size of which is more than 0.2mm;
.Temperature of working environment:2-40 centigrade,transmitted liquid temperature:2-110 centigrade;
The choice of the product
.The users can choose the different type according to the flow ,head in the performance curve.
;
.The inlet and outlet of GPD-S series including the screw connection and the flange connection .You can choose by yourself .The inlet and outlet of GPD series adopts flange connection . lf the dimension of the inlet
and outlet or the shape you need is different from what shows in the catalog ,we can design for you specially.
Usually ,the pump body material of the GPD circulating pump adopts cast iron but we can adopt the brass;
.bronze or stainless steel according to the customer's requirement .When the transport medium is clean water
which is in the normal temperature ,suggest you use cast iron . When it is used in the heating pipeline system which is under ground ,we suggest that the brass or bronze be adopted as the pump body .When it is used in cycle of life hot water,you can use GPD-N(GPD-SN) which pump body material is stainless steel, or GPD-B(GPD-SB) which pump body material is brass or bronze;
Character of structure
.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, rator, shield cover, deflating bolt and so on;
.Seal: The pump isn't sealed with machinery sealing. The stator and rotor of motor are sealed with stainless steal cover. Other parts are all sealed with heat-resisting rubber facing ring, so that there's no leakage;
.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;
