WHY US

Why Zhongzhuo

From selection verification to packaged supply, six dimensions make sure the equipment works on arrival and performs predictably over the long run.

  • R&D

    Design and R&D in one house

    Design, R&D, manufacturing and sales service are integrated in one company. We deliver fluid solutions from selection calculation to packaged supply based on project conditions, and develop custom designs for non-standard duties.

  • CERTIFIED

    Complete management systems

    Certified to ISO9001 quality, ISO14001 environmental and ISO18001 occupational health and safety management systems, and we hold the overall prefabricated pump station inspection report, cylinder inspection report, CFD and FEA analysis reports.

  • FACTORY

    Our own manufacturing plant

    The plant is inside the Xianning National Hi-Tech Industrial Development Zone. GRP cylinder winding, equipment assembly and factory testing are all completed in house, so delivery dates and quality milestones stay under control.

  • SIMULATION

    CFD / FEA verification

    Pump station hydraulics are verified by CFD numerical analysis and cylinder structures by FEA finite element analysis, so vibration, silting and deformation risks are solved at the design stage.

  • DIVERSION

    Precise storm/sewage diversion

    Flexible diversion wells, rotary interception wells and down-opening weir gates form complete packages that give fine control over first-flush interception and storm/sewage separation.

  • SERVICE

    Full life-cycle service

    Site survey, scheme design, installation guidance, commissioning and operator training. After delivery we advise on inspection intervals and spare parts according to actual duty, and after-sales service is never outsourced.

USE CASES

Applications

From source control to smart O&M, equipment is packaged by scenario.

  1. 01

    Source Control & Interception

    Diversion and interception equipment is added at riverside outfalls and combined sewers so first-flush and dry-weather sewage reach the sewage system reliably.

    • Flexible diversion well
    • Prefabricated interception
    • Down-opening weir gate
  2. 02

    Watershed Treatment

    Storage and flushing facilities work with interception works to control non-point pollution entering the river and improve water quality and amenity.

    • Storage tank flushing
    • Vacuum flushing
    • Intelligent jetting
  3. 03

    Outfall Renovation

    Existing outfalls are upgraded as integrated units that handle backflow prevention, flow limiting and wet-weather pumping while minimising excavation.

    • Integrated interception well
    • Hydraulic limiting gate
    • Backflow prevention
  4. 04

    Pipe Network O&M

    Flushing and de-silting of storm and sewage networks using quick-opening flush gates and packaged equipment to cut manual manhole entry.

    • Quick-opening flush gate
    • Network flushing
    • Silt removal
  5. 05

    Older Community Renovation

    In built-up areas short of land, buried prefabricated stations handle sewage lifting and storm/sewage separation while the surface returns to planting or parking.

    • Integrated sewage pump station
    • Storm/sewage separation
    • Buried layout
  6. 06

    Smart O&M

    Equipment status, levels and operating data feed a dispatch platform for remote inspection, fault warning and operation optimisation.

    • Remote monitoring
    • Fault warning
    • Data integration

and get a selection check first

Design flow, head, invert levels of the inlet and outlet pipes and the well position are enough for a preliminary check. Anything missing can be estimated by us from comparable cases and confirmed later by the designer.

COMMON QUESTIONS

FAQ

The questions we are asked most about selection, delivery and after-sales service.

How are the cylinder diameter and height of an integrated prefabricated pump station determined?

The diameter follows from the number of pumps, the maintenance space and the inlet arrangement; the height follows from effective volume, the invert levels of the inlet and outlet pipes and the required cover depth. In practice you first calculate effective volume from design flow and the permitted start/stop frequency, then work back to a diameter using the pump envelope and maintenance access, and finally check deformation under cover and groundwater load cases with FEA.

What is a suitable interception ratio?

The ratio is normally expressed as a multiple of the average dry-weather flow, with n = 1–4 common on combined systems. Too high and a large volume of stormwater is pushed to the treatment plant in wet weather, causing a shock load; too low and first-flush pollution is not intercepted. Verify both the plant capacity and the available storage volume before fixing the ratio.

Can equipment be shipped fully assembled, and what site preparation is needed?

Integrated pump stations, interception wells and pump gates within the usual diameters can all be fully assembled and pressure tested in the factory and shipped as one unit. The site must have the excavation, bedding and lifting access ready with a crane able to work. Once in position, connect the inlet and outlet pipes, power and control cables, then commission with water and the station is ready.

What does after-sales service cover?

Site survey and selection review, installation technical guidance, commissioning and operator training. During the warranty period the equipment and supplied components are handled as agreed in the contract; afterwards we provide inspection advice and spare parts. Operating data can be connected to a remote monitoring platform so anomalies are spotted early.

Can products be customised for non-standard duties?

Yes. Cylinder diameter, depth, inlet and outlet orientation, pump brand and control system can all be adapted to project conditions. For unusual water quality, severe cold or high groundwater we can modify materials and structural solutions and provide the corresponding calculations and verification documents.

How do I obtain a quotation and selection advice?

Send us the project location, design flow, head, invert levels of the inlet and outlet pipes and the well position through the form on this site or by email. Our engineering department completes a selection check first, then issues the equipment list and quotation.
