condensate return pumps introduction • applications for using pmps why choose a pmp instead of an electric centrifugal condensate return pump condensate pumps reliability is the primary purpose for selecting mechanical type pmp’s instead of electric condensate pumps electric pumps require a mechanical seal to prevent the leakage of liquid around the rotating shaft that drives the impeller the liquid being pumped acts as a lubricant so the seal faces of the mechanical seal may rotate freely against each other when the liquid remains relatively cool the mechanical seal could last for many years however hot condensate can flash to steam between the seal faces leading to seal failure a centrifugal pump creates a low pressure zone at the eye of the impeller which draws the fluid into the pump hot condensate can flash into steam in the low pressure zone causing cavitation cavitation happens when bubbles form in the liquid on the inlet side of the pump that will re-compress on

electric pumps introduction simplex vs duplex pump operation a simplex system contains a single pump and receiver tank duplex systems contain two pumps on a common receiver tank allowing the second pump to serve as a back up in case of failure for duplex condensate return pumps the float switch is replaced with a mechanical alternator the mechanical alternator is attached to a float and activates only one pump at a time in an alternating manner the mechanical alternator switches power between the two motors so that the runtime of each pump is shared allowing the system to continue operation in the event of a single pump failure electrical connections electric pumps mechanical alternator/float switch must be ordered separately with duplex units motors controls single-phase motors single-phase motors supplied with these pumps have overload protection and therefore do not require ancillary motors starters single-phase motors can be wired directly to the float switch for simplex units or
