Product Overview

  The GN/GNL vertical condensate pump is a two-stage, single-suction centrifugal condensate pump designed for pumping condensate from condensers and for use in steam turbine generator sets ranging from 750 to 3000 kilowatts—either to remove condensate or to handle other liquids whose physical and chemical properties are similar to those of water. The liquid temperature shall not exceed 80℃.

Structural Description of GN/GNL Vertical Condensate Pumps

  The GN-type condensate pump is horizontal. Its stationary components mainly consist of the suction section, middle section, discharge section, bearing housing, guide vanes, and sealing rings. The axial force acting on the rotating parts is borne by ball bearings, while the radial force is shared by both ball bearings and sleeve bearings mounted on the guide vanes.

  The packing is surrounded by cooling chambers, as are the bearing housing and other components, which can be connected to a cooling-water supply. The water enters axially and exits vertically upward. The horizontal design is lightweight, but maintenance requires dismantling the piping system.

 

 

  The GNL-type condensate pump is a vertical pump whose pump body and pump cover are separated along the axis. The axial force of the rotating parts is borne by ball bearings, while the radial force is shared by both ball bearings and sleeve bearings. Both the pump’s inlet and outlet are cast integrally into the pump body. The lower part of the pump body features semicircular footings, while the upper part has semicircular supports upon which the motor base is mounted. As a vertical pump, it occupies a small footprint and is easy to maintain.

 

 

  The flow parts of the pump are made of cast iron, and the shaft seal is a packing seal. When viewed from the motor end toward the pump, the pump rotates counterclockwise. We supply the pump complete with motor, coupling, base, check valve, and gate valve. If you have any special requirements, please inform our factory when placing your order. Our factory will provide a comprehensive range of high-quality services covering design, manufacturing, testing, installation, maintenance, and training for operating personnel.

  Rotation direction: When viewed from the motor end, the pump rotates counterclockwise.

  Material of main components: The pump body, pump cover, sealing ring, and bushing—components through which the fluid flows—are made of cast iron. The impeller of the N-type condensate pump is made of silicon brass, and the inducer is made of aluminum-iron bronze. The shafts are all made of high-quality carbon steel.

  Pump complete set scope: The complete set includes the pump, motor, coupling, check valve, and gate valve.

Stainless steel vertical pump offers corrosion resistance, high efficiency, and stable performance. Ideal for water supply, industrial processing, and chemical transfer applications.

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.
