Key Points For Selecting Sewage Pumping Stations

1. Tailor Treatment Capacity to Actual Needs

Choosing a sewage pumping station is like buying shoes - a perfect fit matters most. First, calculate two key figures:

- Daily average flow rate: Compute at 1.5 times the peak water usage. For example, if a residential community discharges 300 tons of wastewater daily, select a device with a treatment capacity of 450 tons/day.

- Peak flow rate: The instantaneous drainage volume during rainstorms. It's recommended to choose a model that can handle 2 hours of peak flow.

Don't be misled by sales data - the actual treatment capacity is usually about 15% lower than the marked value. Reserving a margin ensures stability.

2. Material Determines Service Life

Sewage is highly corrosive. Select the right material for different scenarios:

- Cast iron pump body: Suitable for ordinary domestic sewage. Cost-effective but vulnerable to salt corrosion.

- 304 stainless steel: Ideal for oil-containing wastewater from restaurants. Resistant to acids and alkalis but 30% more expensive.

- Engineering plastic: Designed for chemical wastewater. Lightweight and corrosion-resistant but heat-sensitive.

Special attention for coastal areas: Salt in the air can halve the service life of ordinary pump bodies.

3. Configure Intelligent Functions as Needed

Modern sewage pumping stations come with advanced features:

- Remote monitoring: Check operating status via mobile phone, suitable for unmanned stations.

- Self-cleaning design: Rotating blades automatically shred debris, reducing clogging risks by 80%.

- Energy optimization: Automatically adjust power based on flow rate, cutting annual electricity costs by up to 20%.

Avoid paying for unnecessary functions. Basic models are more cost-effective for ordinary residential communities.
