    Product Description

    　　The ZBGRP integrated pumping station is an innovative and intelligent prefabricated pumping station solution offered by the manufacturer Zhonglian Pump Industry with comprehensive service from design, manufacturing, installation, commissioning, and maintenance. It is a new underground collection and lifting system for wastewater, stormwater, and water supply, featuring an intelligent cloud platform for remote monitoring, easy operation, and the ability to operate unattended. It can effectively replace traditional concrete pumping stations, with high integration and volume optimization as its most outstanding features. It not only provides certain hydraulic power to the water but also collects wastewater and stormwater in a designated area, protecting the environment.

    　　The ZBGRP integrated prefabricated pumping station mainly consists of a GRP fiberglass well, submersible/water supply pumps, lifting chain, pipes, valves, level sensors, control system, screen system, and ventilation system, among other components. The appropriate configuration is selected according to different working conditions to adapt to the best usage conditions.

     

    Integrated Pumping Station

    　　The ZBGRP integrated prefabricated pumping station is built completely underground, with advantages such as small occupied area, simple installation and maintenance, low cost and short construction cycle, convenient management, and environmental friendliness. The integrated prefabricated pumping station is suitable for the collection, lifting, and discharge of wastewater and stormwater in municipal projects, railways, underpasses, as well as for raw water intake. For example: dispersed collection and transport of wastewater in scenic areas and water source protection zones; agricultural drainage and irrigation intake; discharge of wastewater and stormwater in residential areas and housing estates; river pollution control and wastewater interception; long-distance transport and lifting in wastewater and stormwater networks; urban flood prevention in low-lying city areas and water accumulation areas at bridges and culverts. It is mainly used when the cost of gravity pipe systems is too high (for example, when the depth is very large); when a more economical solution is needed for long-distance transport; or to lift and transport water to higher elevations.

    　　Daily inspection, maintenance, or replacement of pump parts is easier, without the need to empty the cylinder.

    　　3. Wash valve for integrated prefabricated pumping station

    　　Sediments and debris often accumulate at the bottom of the wastewater tank, adhering to the bottom and sides of the well, occupying the volume of the collector and potentially clogging the pump during pumping. To prevent system shutdown, it is necessary to regularly clean the pump well.

    Washing valve of submersible pump for wastewater

    　　The wash valve is a washing device with adjustable outlet direction, used to prevent sludge accumulation at the bottom of the pumping station.

    　　The valve body is made of cast iron and is connected to the pump body by threading. Its operation is based on the Venturi principle, requiring no power source.

    　　Depending on the size of the well, the pump model, and the risk of sedimentation, the wash valve's washing time can be adjusted between 10 and 400 seconds.

    　　The wash valve features a patented central system, composed of a flexible membrane connected to several rubber balls. When the pump starts, the wash valve opens, the wastewater from the well is suctioned by the pump, and a circulation is formed inside the well that removes sediments (Figure 1).

    Washing valve of submersible pump for wastewater 2

    　　At the set time, the vacuum inside the valve body actuates the rubber membrane, pushing the balls down to close the water flow (Figure 2), expelling the wastewater before the sludge settles again at the bottom.

    　　When the pump stops working, the membrane (Figure 3) and the balls (Figure 4) rise inside the valve body due to the vacuum, opening the wash valve to prepare for the next work cycle.

The main products include: self-balancing multistage pumps, multistage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condenser pumps, and more.

    Q

    Can you help me choose a model?

    A

    Of course! If the water pump model is not selected accurately, it can cause significant problems. After you take it back, it might be either too small to meet the usage requirements or too large, resulting in higher electricity and fuel costs, increasing the operating expenses.

    Q

    Why is the price quotation so slow?

    A

    Because centrifugal pumps are non-standard custom products with many models and a wide price range. Even for the same model, the price varies greatly depending on the materials and configurations used. Taking the most common 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 clearly confirm the relevant information to provide you with an accurate price. Normally, if you provide comprehensive information, we can quote within 5 minutes.

    Q

    What information should I provide when I need a quote?

    A

    Usually, if you want to get an accurate quote, it is recommended that you provide us with the following information: pump flow rate, head, on-site operating voltage, frequency, temperature of the conveyed liquid, pH value, solid particle content, on-site installation conditions (horizontal or vertical installation), and other related details. If you are not very familiar with these, it’s okay; our sales manager will assist you in determining them.

    Q

    Do you have centrifugal pumps in stock?

    A

    There are many models and configurations of centrifugal pumps. Except for a small number of commonly used standard models that are in stock, the vast majority of models and configurations are not stocked and are customized products. We need to first select the pump based on your site conditions such as flow rate, head, medium temperature, pH value, and installation conditions. After determining the pump model and configuration, we can then place an order with the workshop for production.

    Q

    What is your usual delivery time?

    A

    Models in stock can be shipped by the next day at the latest. Others are custom-made, and depending on the product size and specific project conditions, the delivery time is generally between 7-90 days. Please consult our sales manager for details: 0731-88632200 。
