Pump Selection Guidelines
Before ordering, please provide required flow rate, total dynamic head, liquid composition, maximum solid size, liquid temperature, installation depth, pipe size, and available power supply.
For wastewater containing long fibres, large solids, concentrated sludge, or corrosive chemicals, provide details in advance to verify impeller type, solids passage, sealing arrangement, and material selection.
The pump should not operate continuously far from its recommended duty point. Correctly matching the pump curve to the system curve improves energy efficiency and extends service life of bearings and mechanical seals.
Frequently Asked Questions
What type of pump is the 250WQ680-42-132KW-4?
It is a cast iron submersible sewage pump intended for domestic sewage, industrial wastewater and liquids containing suspended solids.
What are its flow rate and head?
Design flow rate is 680 m³/h and design head is 42 m. Actual operating point depends on system resistance and site conditions.
Can this pump operate on a 440V, 50Hz supply?
Yes. This version is configured for 440V, 50Hz power supply. Three-phase electrical connection, starting method and control system should be reconfirmed before production.
What is the maximum solid size the pump can handle?
Maximum solids passage depends on final impeller and hydraulic design and cannot be determined from model number alone. Please provide required solid size for technical verification.
Is an auto-coupling system available?
Yes. Auto-coupling installation is suitable for permanent wet-well applications and makes pump lifting, inspection and maintenance easier.
Can the pump be controlled by a variable frequency drive?
VFD control solution can normally be designed subject to verification of motor, minimum operating frequency, cooling conditions, cable length and VFD settings.
Can it pump corrosive wastewater?
Standard cast iron version is intended for general sewage applications. Acidic, alkaline, saline or chemically corrosive liquids may require stainless steel, protective coatings or other special materials.
