Product Description:

General
Type XR hot water circulating pump, according to API610 and VDAM24297(light/medium duty), it is advanced products developed from type R hot water circulating pumps with high serialization, standardization and generalization. The pumps have advanced performance, stable operation, safe and reliable. It is  used in metallurgy, power stations, chemical industry as well as heating system or closed circle system for handling hot water circulating and exchange-heating. The highest temperature of the liquid can not be over 250℃. Working pressure is not allowed more than 5.O MPa.

Performance range
Capacity Q :1.6~2600m3/s
Head : 5~300m
Working Pressure(P): ≤ 5MPa
Working temperature(T): hot water ≤250℃

The description of pump type
For example:XR200-400A
XR-New Type hot water circulating pump
200-Inlet Diameter of pump(mm)
400-Impeller nominal diameter(mm)
A-Outer diameter of impeller is changed

Construction
Type XR hot water circulating pump is the kind of single-stage, single-suction overhanging centrifugal pump with horizontal axial suction and radial upward discharge.  
The pump casing is radial split which installed horizontally with supported on the center line. Especially suitable for high temperature and high pressure and transport inflammable and explosive liquids.
The shaft seal is mechanical seal or packing seal. The pump used rolling bearings which get lubricated with dilute oil.

The direction of rotation
The rotation of the pump rotor is clockwise looking from the motor to the pump.

Q:My fish tank pump is deep enough, it doesn't bubble up. Without oxygen supply, but it can filter. Does it damage the pump itself?
Three in one pump with a hose connected to the oxygen pump as the pipe above the water so that the air will enter the pump, you can spit bubblesYou put it too deep and put the hose into the water too. Without air, you can't spit bubblesIf the pipe is not long enough, you can find a hose for the oxygen pump instead of a long tube, with the hose out of the water and fixed
Q:Why can domestic pumps sometimes pump water and sometimes not?
You pump 1. is fully automatic, 2. have small pressure tank 3., stop valve should be 1., tap water is interrupted, 2. water intake, water out of harmony
Q:How large is the starting current for a 1.5 kW submersible pump?
If single-phase, the no-load current is about 3.7A, the rated current is about 10A.
Q:Flow 70 cubic meters per hour; lift 35 meters, choose what standard water pump?
1, what liquid transport, whether corrosive, there are no metal particles, or other dirty things2. Installation form (submerged pump, pipeline pump)Clear these issues, you can choose the pump according to requirements
Q:Why should the water pump be opened in time after the pump is started?
Just like peeing, just getting ready to pee, it feels like holding a chicken.
Q:What does the lift of a pump mean?
Lift lift height = water raise height = total lift lift height + water = water is expressed in M by H (m)
Q:What is the definition of the pump in the capacity of the pump?
Work pump, spare pump, repair pump three are interchangeable use, the work pump need to overhaul, repair pump work, work pump is maintenance pump. The capacity of the water pump is not less than 25% of the work pump. If the work pump, spare pump, repair pump model is the same, the work pump 4 units, repair pump at least 1 units, 5 pumps, repair pumps need 2 units
Q:What does the temperature range of the pump mean?
The temperature range refers to the temperature range of the medium in which the pump works. It is mainly determined by the influence of the pump material, especially the material of the shaft seal.
Q:Why is water pumping cool water is normal, but when pumping hot water pressure and flow are very small?
You look at what you pump that is, there are manuals to see how much the media can not exceed the degree,
Q:How do I know the pump pressure?
The "H=100M" in the parameter is the pressure index of the pump. "H" is the height of the head and the height of 100m. Since the 10M lift is approximately equal to 1Kg/cm2 pressure. Your pump is 10Kg/cm2 pressure.Q=18 M3/H, that is, 18 cubic meters of traffic per hour;H=100M, that is, rated head 100M, high head;P=4.0 KW, that is, the motor power is 4 kw.
