At the same time, the diameter of the original pump cutting impeller and its corresponding cutting code remain unchanged. For specific specifications, please refer to the performance curve of each pump for details.

Working pressure (p): The pressure level of the inlet and outlet flanges is 2.5Mpa.

Performance range:

3 Flow Q=0.5~3000m/h

Lift H=4~230m

Operating temperature (t): -45℃~+180℃

Standard speed (n): 2950r/min and 1475r/min

This series of pumps is suitable for transporting clean or slightly contaminated neutral or slightly corrosive liquids that do not contain solid particles. They are not suitable for transporting highly corrosive liquids. If you need this type of pump, you can choose our company’s KCZ chemical process. These series of pumps are mainly used in various industries such as oil refining, petrochemical industry, chemical industry, coal processing industry, paper industry, marine industry, electrical industry, food, pharmaceutical, environmental protection and so on.

1. The pump is a single-stage, single-suction, horizontal cantilever centrifugal pump (see structure diagram)
2. The pump suction port is a horizontal axial structure, and the pump discharge port is a vertical center-up structure, and they are both cast together with the pump body.

3.  The pump body is of volute type, radially split, and supported by feet.

4． The impeller is integrally cast with a rear sealing ring and a balancing hole for balancing the axial force of the pump. Residual axial forces are borne by a pair of back-to-back corner contact ball bearings.

5. The shaft seal cavity is integrated with the pump cover and can be filled with packing seals and various mechanical seals. There is an optional water cooling jacket on the outside of the shaft seal cavity. The equipment of water cooling jacket must be specially requested or used when the temperature of the conveying medium is water exceeds 66°C, and the temperature of hydrocarbon exceeds 120°C.

6． The bearing box is equipped with a set of single row radial short cylindrical roller bearings and a set (two sets) of thrust ball bearings installed back to back. Use oil throw ring to lubricate with thin oil. The oil level is controlled simultaneously by the oil mark (oil sight window) and the oil cup. The oil cup can also play a role in automatically adjusting the oil level. The outer surface of the bearing box is cast with a heat sink, which can be air-cooled (t<120℃). Fan cooling or water cooling (t>120℃) can also be selected. Suspension feet are added to the outer end of the bearing box to assist the stable operation of the pump.

7. In order to easily remove the impeller, shaft, bearings, shaft seal and other parts without having to disassemble the suction pipe and discharge pipe during pump maintenance. This series of pumps uses an extended flexible membrane coupling component. For safety, the coupling component is also equipped with a coupling cover.
8. The pump units are all provided with a common base with anchor bolts.
9. The pump inlet and outlet flanges are manufactured with butt-welded steel flanges, and their connection types with the device’s inlet and outlet pipelines include national standards (GB/T9115.1-), Ministry of Chemical Industry standards HG20615-(American system) and HG20595- (European system), three types are selected by users.

10． Piping system: Whether it is a seal flushing piping system or a cooling water piping system, it is equipped by the pump manufacturer according to the properties and temperature of the transported liquid.

Single-end balanced mechanical seal, pressurized double mechanical seal, unpressurized double mechanical seal and bellows mechanical seal, etc.

1. Petrochemical process pump
2. Prime mover
3. Common base and anchor bolts
4. Flexible extended coupling and coupling cover
5. Butt-welded steel flange at pump inlet and outlet
6. Piping system necessary for pumps, but not for auxiliary pumps

Impeller, shaft, shell seal ring, impeller seal ring, oil cup, rolling bearings, mechanical seal components and various O-rings.

1. The model, specification, material, cooling and sealing piping system and prime mover of the pump should be determined according to the conditions of use. The flow rate, lift, suction pressure or device NPSH, density, temperature and liquid name should be provided when ordering , and indicate the flammability, explosiveness, toxicity, corrosiveness, crystallinity of the liquid and whether the sealing liquid is allowed to penetrate into the pump liquid.
2. If there are special requirements for the prime mover, the user should explain the site conditions, ambient temperature and humidity, installation location and its category (explosion-proof and fire-proof grade requirements), voltage size, etc.
3. This series of pumps generally have mechanical seals. If a packing seal is required, it can be supplied by the user when ordering. However, our company actively recommends that it is more appropriate, more economical and practical to use the original mechanical seal when testing new equipment.
4. The mechanical seal of the pump can be equipped with Dandong Clon Company seals, Shen Pump original joint venture seals, Fushun Hans seals, and seals from the user-specified units (including foreign seals). If not proposed, it will be selected by the manufacturer based on the source of supply.
5. It is not necessary to cut the impeller according to A, B, C…, it can be cut as needed, but it needs to be stated in the “Data Sheet”.
6. All the above must be filled in the “Centrifugal Pump Data Sheet”. You can also order according to the pump model. In this case, there is no need to fill in the “Centrifugal Pump Data Sheet”.
7. When the pump leaves the factory, it does not include any accessories. When the user needs it, it must be re-ordered, either together with the complete pump or separately. And inform the pump model, parts name and code, quantity, material, etc. If it is an impeller, the impeller size or specification also needs to be stated.
