Returning Condensate and When to Use Condensate Pumps .
A pumping system is required to transport and recover condensate once the system backpressure becomes higher than the lowest possible trap inlet pressure. System backpressure can be calculated by totaling the sum of 3 discharge side components: Lift after a steam trap, pump, or pump/trap; Frictional loss of the transport piping

Steam Condensate - an overview | ScienceDirect Topi
Steam–condensate thermal engineering systems are applied in numerous industrial sectors. A scheme of a simple open conventional steam–condensate system is given in Figure 5.6.The steam produced in the boiler house is transported via pipelines to the heat consumers (heat exchangers; heat apparatus), where the steam condenses. At the exit of the heat exchangers, condensate batteries ...

Steam Basics Part 17: Condensate Pump Discharge Balance .
Condensate Pump Operation is Different than most Hydronic Pumps. The system curve for condensate pumps is much flatter than in most hydronic systems. Let’s use an example to illustrate this. In the example below, we assume the friction loss at 90 GPM is 14.5 feet or 6 PSIG. The elevation is shown as 12 feet or 5 PSIG.

Large Steam System Condensers - Heat Exchanger - Engineers .
Normally, air ejectors consist of two suction stages. The first stage suction is located on top of the condenser, while the second stage suction comes from the diffuser of the first stage. The exhaust steam from the second stage must be condensed. This is normally accomplished by an air ejector condenser that is cooled by condensate.

The main condensate pump is fitted with a gate valve in the suction line and a stop-check valve in the discharge line. All condensate pumps are vented to their associated condensers by vent lines from the suction side of the pump casing. The piping between the condensate pumps and the condenser are under atmospheric pressure.
