For commercial or industrial systems, the average solids size is 2 ½” or larger. Flow and total dynamic head (TDH) are integral in selecting a pump. Your water flow requirements, measured in GPM, are based on the number of people using the system, peak usage times and the number of water fixtures (e.g. toilet, sink).
How many fixture units is a sewage ejector pump?
Two (2) fixture units shall be allowed for each gallon per minute (3.78 Lim) of flow.
How does sewage ejector pump work?
Sewage Ejector pumps do not have grinding blades. They use a spinning that intakes the raw sewage through the bottom of the pump and forces it under pressure out of the outlet and into the discharge pipe. Sewage Ejector pumps are generally designed to handle up to 2” diameter solids.

How far can a sewage pump pump?
How do you calculate pump size?
Calculations:
- Flow Rate (Q) =Q1x1.
- Actual Total Head (After Friction Losses) (H) = (h1+h2)+((h1+h2)xf)
- Actual Total Head (After Friction Losses) (H)=50+(50×30%)= 65 Meter.
- Pump Hydraulic Power (ph) = (D x Q x H x9.
- Pump Hydraulic Power (ph) = (1000 x 0.005 x 65 x9.
- Motor/ Pump Shaft Power (ps)= ph / pe = 3 / 80% = 4KW.
