Condensate pumps

Electric pumps

Sizing and selection - Cascade pump duties

Information required for sizing and selection:

1. Average rate at which condensate returns to the receiver in kg/h.

2. Total pumping delivery head, including lift and friction loss in pipe and fittings.

Sizing and selection

For correct selection plot the condensate return rate to be handled against the total head required (static + friction) and select the appropriate

unit. If selection is borderline then select the next largest unit.

For duty/standby selections the chart capacities should be halved.

Selection example: The condensate return rate is known to be 7000 kg/h and the total head required is 25 m. Draw a horizontal line

from the known 25 m head required until it crosses the vertical line which represents the known 7 000 kg / h condensate which needs to be

handled. For this example the selection would be an SPS300-403 condensate recovery unit.
