How to Select Suitable YW Liquid-Submerged Sewage Pump Model

Correct model selection of YW liquid-submerged sewage pump relies on 5 key on-site working condition parameters:
（1）Required Flow Rate: Confirm hourly sewage output of wastewater pool, select pump flow higher than actual peak sewage volume by 10%-20% for surplus capacity.
（2）Delivery Head: Calculate vertical lifting height plus pipeline elbow, valve resistance loss, select pump rated head higher than total actual head by 10%-15%.
（3）Medium Property: Neutral sewage choose standard cast iron YW pump; weak acid/alkali corrosive wastewater select stainless steel YWP anti-corrosion version. Check medium solid particle size and fiber length to confirm anti-clog impeller matching.
（4）Submerged Depth: Measure sewage pool effective liquid depth, customize extension pipe length to control submerging depth within 0.5~7m.
（5）Installation Mode: Temporary construction drainage choose single pipe installation; fixed industrial sewage station select double pipe hard pipeline installation.

After confirming above data, match inlet caliber, flow, head and motor power via YW pump model coding rule to lock accurate model number. Consult pump manufacturer for parameter optimization if medium density exceeds 1.3×10³kg/m³ or pH value out of 5-9 range.
