Product Overview

The GW-type pipeline sewage pump is a new-generation, non-clogging pipeline sewage pump developed by Lian Pump Industry—a sewage pump manufacturer—on the basis of introducing advanced foreign technologies and taking into account the specific usage characteristics of domestic sewage pumps. This pump boasts remarkable energy-saving performance, anti-entanglement capabilities, no clogging, automatic installation, and automatic control features. It demonstrates exceptional effectiveness in conveying solid particles and long-fiber waste.

 GW-type pipeline sewage discharge pump

The GW-type pipeline sewage pump is easy to install and has a wide range of applications. It can serve as a general-purpose pipeline pump for pressurizing and delivering water in high-rise buildings, and it can also handle sewage containing particulate matter and fibers. In addition to sewage conveyance, this pump is suitable for use as a drainage pump, a filter rinse pump, and a condensate circulation pump. The GW-type pipeline sewage pump features a unique impeller design and a new type of mechanical seal, enabling it to efficiently transport media containing solids and long fibers. Compared with conventional impellers, the impeller used in this pump adopts either a single-channel or a dual-channel design, resembling a bent pipe of the same cross-sectional size. This design provides excellent flow characteristics. Coupled with a properly designed volute chamber, the pump boasts high efficiency. Moreover, the impeller has undergone both static and dynamic balance tests, ensuring that the pump operates without vibration.

Product Parameters

Meaning of the model designation for the GW-type non-clogging pipeline sewage pump:

100 GW 100-15-7.5

100 – Nominal diameter of pump discharge outlet (mm)

GW – Pipeline-free drainage pump

100 – Rated flow rate (m³/h)

15 – Rated head (m)

7.5 – Rated Power of the Motor (kW)

 

Structural features, performance, and advantages of the GW-type non-clogging pipeline sewage pump:

Large-flow, anti-clogging hydraulic component design; dry installation for easy maintenance; electromechanical integration with a compact footprint.

Pipeline-style Wastewater pump The hydraulic performance is advanced and mature, and the product has undergone performance testing, with all indicators meeting the relevant design requirements.

The pipeline sewage pump is suitable for conveying sewage and waste containing particulates in industries such as chemical engineering, petroleum, pharmaceuticals, mining, papermaking, power plants, municipal wastewater treatment, municipal engineering, and public utility drainage systems. It is used for discharging heavily polluted wastewater from industrial and commercial facilities, sewage pumping stations in residential areas, water distribution systems at municipal wastewater treatment plants, drainage stations in civil defense systems, water supply equipment at waterworks, sewage discharge from hospitals and hotels, construction sites in municipal engineering projects, auxiliary machinery supporting mining operations, rural biogas digesters, agricultural irrigation systems, and other applications involving the conveyance of sewage and waste containing particulates. It can also handle clean water and media with mild corrosivity.

Features:

1. The pipeline sewage pump is directly coupled to the motor via a common shaft, making it a mechatronic product with a compact structure and stable performance.

2. The large-flow, anti-clogging hydraulic component design significantly enhances the capacity to pass debris, enabling it to effectively handle fibrous materials up to five times the diameter of the pump’s inlet and solid particles with diameters approximately 50% of the pump’s inlet diameter.

3. The design is reasonable, the matching motor is appropriately selected, resulting in high efficiency, low noise, and significant energy-saving performance.

4. The mechanical seal is made of hard, wear-resistant tungsten carbide, offering features such as durability and excellent wear resistance, enabling the pump to operate safely and continuously for over 8,000 hours.

5. The pipeline sewage pump features a vertical design, with the inlet and outlet centerlines lying on the same horizontal plane and the inlet and outlet flange specifications being identical, making installation and removal extremely convenient.

6. It occupies a small footprint and does not require a dedicated machine room, thereby saving substantial infrastructure costs. By adding a protective cover to the motor’s fan blades, the entire unit can be placed outdoors for operation.

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.
