Product Overview

　　Condensate pumps are a series of products designed for the conveyance of condensate water. The N-type condensate pump is used in thermal power plants to transport condensate water and other liquids with properties similar to condensate water; it can also be applied in other locations where the medium has characteristics similar to condensate water. These pumps are suitable for conveying condensate water at temperatures below 120℃ or liquids with physical and chemical properties similar to clear water. The NB, NBA, and NBA-type pumps are specifically designed for pumping condensate from condensers at temperatures not exceeding 80℃, as well as for use in condensate extraction in steam turbine generator sets ranging from 750 to 3000 kilowatts and in other similar applications. The 100N130, 100N160, 150N110, 150N130, 150N180, 200N180, 200N32, 80N45×4, 100N45×5, and 150N60×4 pump models, when equipped with cooling water supplied to both the stuffing box body and the packing gland, can also serve as drainage pumps. These pumps can be fitted with mechanical seals and are capable of handling liquids up to 150℃; other pump models are suitable for liquids with temperatures below 80℃.

 

 

N-Type Horizontal Centrifugal Condensate Pump—Parameter Range and Model Description

　　Flow rate Q: 8–200 m³/h

　　Head H: 38–180 m

　　Model Description: The pump model is designated based on its dimensions and performance characteristics.

　　For example: The meanings of 3N6×2 and 4N6A are as follows:

　　3 or 4—divide the diameter of the suction pipe by 25.

　　N - Horizontal Cantilever Condensate Pump

　　6- Round the single-stage head design value after dividing by 10.

　　That is, the head of a single-stage pump is around 60 meters.

　　2-stage, indicating that the pump has two stages.

　　A—The impeller has been cut (outer diameter reduced).

　　For example: 3N6×2

　　3——The pump’s inlet diameter is 3 inches.

　　N——Horizontal Cantilever Condensate Pump

　　6 —— Round up the design point head after dividing by 10.

　　2——The pump has 2 stages.

　　For example: 100NB-45

　　100——The pump’s inlet diameter is 100 mm.

　　N——Condensate pump

　　B——Suspension type

　　45—The pump’s designed head is 45 m.

 

Introduction to the Structure of an N-Type Horizontal Centrifugal Condensate Pump

　　Pumps of types N, NB, and NBA are single-stage, single-suction, cantilever centrifugal pumps. The N-type pump features a two-stage design, while the others have a horizontal design. These pumps are available in two structural configurations: with and without an inducer wheel. They boast a compact structure, smooth and reliable operation, high efficiency, and excellent cavitation resistance. They feature standardized design, high standardization, and excellent versatility.

　　Material for flow parts: cast steel or stainless steel; other materials can also be selected according to user requirements.

　　1. Variety
　　 N-type condensate pumps come in various structural configurations, including horizontal cantilever single-stage, two-stage, and single-stage pumps equipped with an inducer. There are more than 10 different models available. The single-stage models include 3N6, 3N6G, 4N6, 4N6G, 4N6A, as well as 100N130 and 100N160; the two-stage models include 2.5N3×2, 3N6×2, and 4N6×2; and the single-stage models with an inducer include 6N6, 150N110, 150N130, 150N180, 200N32, and 200N180.

　　2. Supporting Component
　　The supporting structure of the variety is identical. The main components include a bracket, front and rear bearing press covers, and a shaft assembly supported by front and rear radial ball bearings mounted on the bracket. The ball bearings also bear any unbalanced axial forces. Lubrication is provided by thin oil, and the oil level can be monitored via the oil-level indicator. Both the front and rear bearing press covers are equipped with felt seals as shaft seals to prevent oil leakage. The holes at the pipe plugs are used for oil filling. During cleaning and oil replacement, the oil is drained through the threaded holes.
 

　　3. Sealing and Transmission
　　The pump uses a soft packing seal, and a replaceable uranium sleeve is installed at the uranium seal area.

　　The pump is driven by an electric motor via an elastic coupling, and when viewed from the direction of transmission, the pump rotates counterclockwise.

　　4. Working Part
　　Single-stage: The main components include an impeller made of brass 80-3, which is fixed to the shaft via a key. The shaft is made of high-quality carbon steel No. 45. The impeller is housed within the pump chamber formed by the pump casing and pump cover, both cast from wear-resistant cast iron HT20-40. The power unit drives the shaft and impeller—both supported by bearing sleeves—via a coupling. The bearing sleeve, made of wear-resistant cast iron HT20-40, serves as a water-lubricated bearing between itself and the bushings (designated as 6N6 and 4N6×2). Inside the stuffing box at the rear of the pump housing, there is a packing ring along with a packing oil-soaked graphite asbestos rope. An open-type packing gland nut is used to compress the packing material tightly through extended double-head bolts, allowing for adjustable tightness. High atmospheric pressure water is introduced externally through a connecting pipe and directed toward the packing ring, thereby creating a sealed cavity throughout the stuffing box that prevents air from entering the pump and also keeps the pump’s internal water from leaking outward—only a small amount of lubricating water drips out. The impeller is equipped with balance holes that connect the high-pressure area to the low-pressure inlet area, effectively eliminating axial thrust on the shaft. To prevent wear on the pump casing and pump cover, facilitate repairs, and ensure good sealing performance, sealing rings are installed on both the pump casing and pump cover. The upper part of the pump casing features threaded holes for venting purposes; during shutdown and maintenance, the water inside the pump can be drained through these threaded holes. For easy removal and installation of the pump casing and pump cover, lifting screws are provided. Pressure-measuring ports are also fitted at both the inlet and outlet.

　　Two-stage: The remaining components are identical to those of the single-stage pump; only the pump body, pump cover, and intermediate guide vanes form two working chambers. Each chamber is equipped with a first-stage impeller cast from silicon brass 80-3 and an impeller made of cast iron HTA20-40CUMO, respectively.

Single-stage impeller with an inducer wheel: The rest is identical to that of a single-stage impeller, except that the impeller material is aluminum-iron bronze. An inducer wheel made of aluminum-iron bronze is added upstream of the impeller to improve cavitation performance.

Q

What is your typical delivery time?

A

Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。

Q

Do you have centrifugal pumps in stock?

A

Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.

Q

What information should I provide when requesting a quote?

A

Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.

If you are not sure, don't worry, our business managers will assist you in determining this.

Q

What products do you mainly produce?

A

Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.

Q

Could you help me with the selection?

A

Certainly! If the water pump model is not selected accurately, there will be big problems. If you choose a smaller one, it won't meet your needs; if you choose a larger one, it will waste electricity and fuel, increasing your costs.

Q

Why is it so slow to get a price quote?

A

Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
