Inside AdvantagesMechanical condensate pumps operatewith a spring-assisted float mechanism,which means the springs themselves area major wear point. Armstrong pumping

traps have large-diameter Inconel X-750springs, which provide superior corro-sion resistance and longer service lifethan those in competitive models. Forother inside advantages, see below.

Notice the difference in spring design from

the industry standardspring set (left)

and the ArmstrongInconel spring set.

Corrosion resistanceEntire float mechanism is stainlesssteel. Float is Heliarc welded to avoidthe introduction of dissimilar metals,which could lead to galvanic corrosionand float failure.

Non-electricUtilizes inexpensive steam, air or gas for operation and has no seals,motors, impellers or electric components, which frequently fail.

Long life anddependable

serviceSimple float/

spring operation and rugged

all-stainless steelconstruction allow

for long, trouble-freeservice life.

Intrinsically safe due to all-stainless steel construction

of mechanism.

Externally replaceablevalve and seat assembly

Maintenance is a “snap” with hardenedstainless steel valves that can be cleaned

or replaced without cap removal.

Stress chloride corrosion resistanceInconel X-750 springs havehigher resistance to the stress that causes lower-gradestainless steel springs to fail.

Wear and corrosionresistanceMechanism frame assembly is constructed of rugged investment-cast stainless steel components.

Compact, low-profile design

Low-profile design allows formaximum pump capacity with

minimal fill head and floor spacerequirements. PT-300 Series

horizontal tank design providesthe highest capacity with thelowest profile on the market.

Filling1. During filling, the steam, air orinert gas inlet and check valve onpumping trap outlet are closed. The vent and check valve on theinlet are open.

Begin Pumping2. Float rises with level of condensateuntil it passes trip point, and thensnap action reverses the internalvalve positions shown in step one.

End Pumping3. Float is lowered as level of condensate falls until snap actionagain reverses the internal valve positions.

Repeat Filling4. Steam, air or inert gas inlet andtrap outlet are again closed whilevent and condensate inlet are open. Cycle begins anew.

Effective Condensate Management = Energy Savings

The most basic part of energy management is utilizing all valuableBtu within the steam system. Depending on the pressure, condensateexiting a trap contains approximately 20% of the heat energy trans-ferred at the boiler in the form of sensible heat. Effective recovery of condensate reduces three tangible costs of producing steam:

• Fuel/energy costs associated with producing steam

• Boiler water make-up and sewage treatment

• Boiler water chemical treatment

These savings can be calculated using the attached savings form.Returning condensate saves money, energy and the environment. Pour money and energy savings back into your plant—not down the drain.

*Btu/lb from direct steam injection **Estimated equipment and installation cost†Cost to operate in example assumes an “open” vented system. If pump trap is used in “closed loop” application, steam operation cost is negligible.

Energy costs will vary from plant to plant and regions of the world. Values shown are conservative. Complete this form using yourfacilities’ numbers to determine annual savings in your plant by returning condensate. If some costs are not known, use the figuresbelow for conservative estimates.
