In this age of increasing energy costs, Spence Engineering Co., recognized the need for a more efficient and cost effective way for their customers to reap the benefits of returning condensate. To meet this need, Spence Engineering proudly introduces the all new P3-PistonPower Pump™ series of non-electric condensate pumps. With its unique springless dual-piston design, the P3 is designed for returning condensate more reliably and efficiently than any currently available spring design, non-electric pump as well as centrifugal pumps.

Why Return Condensate?

In a steam system, steam transfers its energy in the form of heat and the by-product of this process is condensate as the steam changes phase from a vapor to liquid. When this change occurs, between 10-25% of the heat energy created by the boiler remains in the removed condensate. Therefore, when condensate is not being returned, valuable energy is being wasted!

Effective Condensate Recovery Cuts Costs By:

• Using less fuel/energy by reproducing steam from already high temperature condensate

• Reducing the maintenence of boiler water make-up and chemical treatment

• Minimizing disposal of high temperature condensate

• Reducing boiler blowdown

Why is Pumping & Removal Necessary?

Pumping is necessary when the condensate return pressure is higher than the process/source condensate pressure. This includes the vertical rise that the condensate needs to climb. In any system with a heat exchanger or process equipment, there needs to be removal of the condensate to provide a stable environment.

Efficient Removal:

• Improves product quality by stabilizing the system temperature

• Prevents excessive corrosion from sitting condensate

• Improves safety and prevents equipment damage and noise caused by water hammer

Why Doesn't Everyone Return Condensate?

Historically, all pump designs utilized a spring-snap mechanism intended to insure the shift of the valve positions. Over time and under many operating conditions the spring/ snap mechanism would fail or leak and therefore, no longer pumped. When the mechanism failed, it was difficult and costly to repair. It was also problematic if the system was located in a remote or dangerous location.

Centrifugal pumps, another option, also present problems, such as the need for electricity, failure of mechanical and rotary seals and issues with cavitation.

Spence Engineering's Answer: The P3 Advantage

More Reliable Non-Electric Condensate Pump

The all-new patent-pending P3-PistonPower Pump™from Spence Engineering is designed specifically to remove condensate under all operating conditions, even those in which previous non-electric pumps came up short.

By designing and providing a new mechanical pump design, Spence Engineering has tackled the major issues encountered during the use of the currently available mechanical pumps; pump life, reliability, maintenance, capacity, steam consumption, and heat exchanger stall.

NEW VALVE DESIGN

• Valves on top of the pump remove vital components from potentially dirty or corrosive condensate.

• Made of all Stainless Steel components

• Uses a more reliable, longer lasting spool-type valve design rather than a metal-to-metal globe-type design

- Over time the metal-to-metal globe design wears down reducing the capacity

- Spool-type design uses special polymer seals which reduce wear and friction

• Larger orifice allows more motive by reducing the cycle time

NEW SPRINGLESS LINKAGE DESIGN

• Cleaner, simpler design

• No spring to break

• Minimal pivots points, movement, and force eliminate friction and wear and possibility of stalling or sticking

• Smoother operation, no hard impacting or shocking from the spring snap

• Made of all Stainless Steel components

3 YEAR/3 MILLION CYCLEWARRANTY

New Design Advantages

The inspiration for designing the revolutionary new pump was to provide a more dependable pump for condensate recovery however, reliability is just the beginning of story for the all-new P3-PistonPower Pump™. The more rugged, long lifetime dual-piston design has created an extremely versatile, efficient and easy to maintain pump mechanism for almost all applications and environments.

Increased capacity compared to similar spring design pumps:

• Due to a combination of larger orifice, less friction, and longer travel

• Therefore, this may allow you to use a smaller pump than was previously allowed saving you money and valuable space.

Easy Maintenance

• Secondary piston can be accessed and replaced from the top.Able to work up to 300 psi motive steam pressure

Interchangeability

• Mechanism can fit in most current spring pumps out on the market today. Extremely versatile, can be used no matter what flow conditions are present

• There is no minimum flow required and it can operate as needed, from almost no load up to its rated maximum capacity.

Requires no electricity or controls

• Ideal for remote or hazardous locations,

• Makes installation easier and less costly

• Reduces overall costs associated with operation and maintenance.

Greater efficiency

• Uses the steam already present in the system.

• It can also use air or other pressurized gas.

No cavitation issues & no mechanical/rotary seals

• Reduces maintenance costs

• Increases the temperature capability.

Spence Engineering is the manufacturer of Nicholson Steam Trap, offering a full line of steam traps and clean steam products and Rockwood Swendeman Cryogenic Valves. Spence Engineering Company products are used in a wide range of applications including: HVAC systems, feed water & fuel systems, heat exchangers, district energy systems, water purification systems, pulp & paper industry, chemical &petrochemical industries, food, beverage and dairy industries.

Spence regulators are used extensively in heating systems, institutions, public utilities, district heating systems, process systems, and major industrial plants.Since it's founding in 1926, Spence Engineering Company has engineered for reliability and longevity. It was the lack luster performance and the frequency of maintenance calls for pressure reducing valves of the 1920s that inspired Paulsen Spence to design the Spence Type ED in 1925. The ED was the first normally closed, pilot-operated, diaphragm actuated pressure regulator andit revolutionized the way energy producers supplied low-pressure steam to their customers by providing greatly improved accuracy in pressure control. Since it's earliest days Spence has continued it's "History of Innovation" with new product development and improvements to Spence's "quality first" manufacturing philosophy.

This has enabled Spence to develop and manufacture quality steam specialty and fluid control products that meet the changing needs of today's HVAC and Industrial marketplaces, just as Paulsen Spence did in the early 1900s.
