For contractors and wastewater system integrators, purchasing several pump sizes within one order can simplify project sourcing and equipment coordination.
This was the requirement for a recent Nawasiwa project involving 40 submersible sewage pumps.
Rather than purchasing 40 identical units, the customer selected three specifications:
The pump capacities range from 10 m³/h to 25 m³/h, while the required heads range from 12 to 15 metres.
This combination is suitable for a wastewater system containing pumping points with different inflow conditions.
The 1.5 kW model can handle lower-volume duties, while the 2.2 kW unit provides additional capacity. For locations requiring greater wastewater transfer volume, the 3 kW model offers a rated flow of 25 m³/h.
All three models use a submersible installation arrangement, helping simplify the layout of sewage pits and wastewater pumping stations.
For bulk international orders, we can prepare different pump models within the same shipment according to the project schedule and technical list.
Typical information required for sewage pump selection includes flow rate, pumping head, outlet diameter, liquid characteristics, solid size, power supply and installation method.
The Nawasiwa shipment is a good example of a multi-model sewage pump package developed for an overseas wastewater project.
