Product Introduction
ISG vertical single-stage single suction pipeline pump is an efficient and energy-saving product designed and manufactured based on the performance parameters of IS single-stage single suction centrifugal pump and pipeline pump, referring to ISO2858 and the national pipeline pump standard JB/T53058-93. The pump is designed using force model optimization. At the same time, based on different usage temperatures, media, etc., hot water pumps, high-temperature pumps, chemical pump oil pumps, etc. are derived from the ISG type, which are currently standardized and promoted products in the country.

Product Features
1. The pump is a vertical structure with the same inlet and outlet diameters, and they are on the same centerline. It can be installed in the pipeline like a valve, with a compact and beautiful appearance, small footprint, and low construction cost. If a protective cover is added, it can be used outdoors
2. The impeller is directly mounted on the extended shaft of the motor, with a short axial dimension and compact structure. The pump and motor bearings are reasonably configured, which can effectively balance the radial and axial loads generated by the pump operation, thereby ensuring low vibration noise during pump operation balance.
3. The shaft seal adopts mechanical seal or a combination of mechanical seals, using imported titanium alloy sealing rings, medium-sized high-temperature resistant mechanical seals, and hard alloy materials for wear-resistant seals, which can effectively increase the service life of mechanical seals.
4. Easy installation and maintenance, no need to disassemble the piping system, just remove the pump coupling nut to extract all rotor components.
5. Pumps can be operated in series or parallel according to the requirements of flow rate and head.
6. Vertical and horizontal installation of pumps can be adopted according to the requirements of pipeline layout.

application
1. ISG vertical single-stage single suction pipeline pump is used for conveying clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden irrigation, fire pressure boosting and equipment matching. The operating temperature T is ≤ 80 ℃.
2. The IRG (GRG) type hot water (high temperature) circulation pump is widely used in energy, metallurgy, chemical, textile, papermaking, as well as hotels, restaurants, and other boiler high-temperature hot water pressurized circulation transportation and urban heating system circulation pumps. The IRG operating temperature T is ≤ 120 ℃, and the GRG operating temperature T is ≤ 240 ℃.
3. IHG vertical stainless steel chemical pump is used for conveying liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. It is suitable for departments such as petroleum, chemical, metallurgical power, papermaking, food, pharmaceuticals, and synthetic fibers. The operating temperature is T: -20 ℃ -120 ℃.
4. YG pipeline oil pump, used for transporting petroleum products such as gasoline, diesel, kerosene, etc., operating temperature T: -20 ℃ -120 ℃.

Conditions of Use
1. The suction pressure is ≤ 1.0Mpa, or the working pressure of the pump system is ≤ 1.6Mpa, that is, the pump suction inlet pressure+pump head is ≤ 1.6Mpa, and the pump static pressure test pressure is 2.5Mpa. Please specify the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6Mpa, it should be separately stated when ordering, so that the overcurrent components and connecting parts of the pump can be made of cast steel materials during manufacturing.
2. Environmental temperature<40 ℃, relative humidity<95%.
3. The volume content of solid particles in the conveyed medium shall not exceed 0.1% of the unit volume, and the particle size shall be less than 0.2mm
Note: If the medium used is with small particles, please specify when ordering so that wear-resistant mechanical seals can be used.

Fault causes and troubleshooting methods

Fault phenomenon
Possible causes
Troubleshooting
1. The water pump is not producing water
a、 The import and export valves are not open, the inlet and outlet pipelines are blocked, and the impeller of the flow channel is blocked.
b、 The motor is running in the wrong direction and has a slow speed due to phase loss.
c、 The suction pipe is leaking air.
d、 The pump is not filled with liquid and there is air inside the pump chamber.
e、 Insufficient imported water supply, high suction, and leaking bottom valve.
f、 Excessive pipeline resistance and improper pump selection.
a、 Check and remove blockages
b、 Adjust the motor direction and strengthen the motor wiring
c、 Tighten all sealing surfaces and eliminate air
d、 Open the pump cover or open the exhaust valve to exhaust the air
e、 Shutdown inspection and adjustment (this phenomenon is prone to occur when using grid connected water pipes and suction pumps)
f、 Reduce pipeline bends and reselect pumps.
2. Insufficient water pump flow
a、 First, check the cause according to 1.
b、 Pipeline, pump impeller blockage, scale deposition, and insufficient valve opening
c、 Low voltage
d、 Impeller wear
a、 First, press 1. Exclude
b、 Remove the obstruction and readjust the valve opening.
c、 Stabilize voltage.
d、 Replace the impeller.
3. Excessive power
a、 Exceeding the rated flow usage.
b、 The suction distance is too high.
c、 The pump bearings are worn.
a、 Adjust the flow rate and turn down the outlet valve.
b、 reduce
c、 Replace the impeller
4. Noise vibration
a、 The pipeline support is unstable.
b、 Liquid mixed with gas.
c、 Generate cavitation.
d、 The bearing is damaged.
e、 The motor is running under overload and overheating.
a、 Stable pipeline
b、 Increase suction pressure and exhaust
c、 Reduce the vacuum degree
d、 Replace bearings
e、 Press 5 to adjust.
5. Motor overheating
a、 Excessive traffic and overloaded operation.
b、 Rubbing.
c、 The motor bearings are damaged.
d、 Insufficient voltage.
a、 Close the outlet valve.
b、 Check and eliminate.
c、 Replace the bearings.
d、 Stabilize voltage.
6. Water pump leakage
a、 Mechanical seal wear.
b、 The water pump body has sand holes or cracks.
c、 The sealing surface is uneven.
d、 Loosen the installation bolts.
a、 Replace.
b、 Welding repair or replacement.
c、 Repair.
d、 Durable.
