Project Overview
Shangli motors were used on booster pumps serving a large-scale turf producer in the United Kingdom. The irrigation system was designed to deliver up to 400 m³/h of water to a main irrigation area approximately 2 km from the collection point.
The installation combined an initial water-lifting stage with two successive booster stages. Shangli's motor contribution covered the 45 kW and 55 kW drives used on the booster pumps.
This case focuses on the booster-pump motors and their role within the wider irrigation installation. The complete pumping system, hydraulic design and containerised pump packages were not supplied by Shangli.

Initial Situation
Water had to be transferred from a purpose-built collection sump to the main turf irrigation area. The route extended approximately 2 km and required the pumping system to overcome more than 50 m of static lift as well as friction losses.
Changes in the source water level also had to be considered. The project therefore used a staged pumping arrangement rather than relying on a single pump group to perform the entire transfer.
The irrigation network was based on a ring-main layout, with water-hammer considerations included in the system design. The objective was to provide the flow and pressure needed to distribute water across the turf-growing area.
Three-Stage Pumping Arrangement
| Stage | Equipment | Motor Rating | Function |
|---|---|---|---|
| Initial water lifting | Three KCM150-series submersible pumps | 11.2 kW per pump | Lift water from the collection sump and feed the first booster stage. |
| First booster stage | Three MEC-A3/80 horizontal single-impeller centrifugal pumps | 45 kW Shangli motor per pump | Increase pressure and transfer water towards the next booster stage. |
| Second booster stage | Three MEC-MR80-3/2 multistage pumps | 55 kW Shangli motor per pump | Provide the additional pressure required by the irrigation network. |
The initial submersible pumps were installed on a pontoon arrangement. They supplied the first group of booster pumps on the bank, approximately 50 m away.
The first booster group then transferred water towards the multistage booster pumps. Together, the stages were designed to support the stated system flow and the pressure requirements of up to 12 irrigation sprinklers.
The 400 m³/h figure describes the overall system design flow. It is not the flow of each pump and should not be interpreted as a motor rating.
Shangli's Motor Contribution
Shangli motors provided the mechanical drive for the two booster stages: 45 kW motors for the horizontal single-impeller pumps and 55 kW motors for the multistage pumps.
These motors formed part of the pump packages responsible for increasing pressure along the transfer route. Their role was distinct from that of the initial submersible pump units, which lifted water from the collection sump.
The two motor ratings corresponded to different pump duties within the installation. The required system flow and pressure were delivered by the coordinated pumping arrangement, not by the motors independently.
Containerised Booster Packages
According to the project information, Caprari UK assembled the booster pumps within shipping containers. The packages incorporated suction and delivery manifolds, including digital water metering.
Variable-speed controllers were incorporated through coordination with the control-panel manufacturer. The packaged arrangement was intended to simplify site installation by providing defined hydraulic connections and electrical supply interfaces.
The containerised format also allowed for future relocation or additions as irrigation requirements changed. This flexibility belongs to the overall package design rather than to the motor supply alone.
Project Outcome and Application Value
The completed package provided a staged pumping solution for the turf producer's water-transfer and irrigation requirements. The design combined source-water lifting with successive pressure increases along the route to the irrigation area.
Within that arrangement, Shangli's 45 kW and 55 kW motors served as the drives for the six booster pumps. The project illustrates the use of different motor ratings within one coordinated water-handling system.
The stated flow and sprinkler coverage are project design figures. This case does not claim a separately measured energy-saving percentage, a specific payback period or an independently verified operating lifetime.
