Condensate Return & Boiler Feed Pumping Units

No, we can sell condensate return pumping units from any manufacturer, including Shipco, Mepco, Hoffman and other brands.

Condensate Return Pumping Units are packaged assemblies consisting of a receiver (either Cast Iron or Steel), Pump and Motor (either Simplex or Duplex) and control device to turn the pump motor on or off.  They are designed to collect condensed liquid at remote locations in a steam system and move it back to the boiler room. The Units can be powered by either electricity or steam. Electrically powered units are the norm while the steam-driven units are typically used in hazardous environments or where electricity may not be readily available.

• System Capacity (generally a function of boiler horsepower) and determines tank size
• System Type (Vacuum or Gravity)
• Outlet Pressure requirement (which determines motor HP)
• Electrical requirement (single or three phase, voltage)
• Type of  motor (TEFC, Explosion-Proof, Open Drip)
• NPSH (determines type of pump)
• Tank material (determines service life of receiver)
• Single or Double Pump Design
• Accessories (e.g. Pressure Gauge, Water Level Gauge Glass, Isolation Valve, etc.)

Boiler Feed Pumping Units are packaged assemblies consisting of a receiver (either Cast Iron or Steel), Pump and Motor (either Simplex or Duplex) and control device to turn the pump motor on or off (usually controlled by the boiler). They are designed to send condensed liquid from the system, augmenting it with make-up water when required, to the boiler. They are generally larger than the Condensate Return Pumping Unit(s) found in the system as they must store boiler feed water until the boiler calls for additional water. Many of the same criteria as used to select a Condensate Return Pumping Unit are used to select a Boiler Feed Pumping Unit with the additional variables:

• Type of make-up water control (float or solenoid)
• Horizontal or vertical design

• Achieve substantial energy savings by collecting the already heated condensate and returning it to the boiler thereby lowering the consumption of fuel needed to heat the much cooler make-up water.
• Lower operating costs by reusing condensate already chemically treated thereby reducing the consumption of additional chemicals needed to treat fresh make-up water.

• Simplex and Duplex Pump Packages
• Carbon-Steel Tanks or Optional Stainless Steel
• High Efficiency 3450 RPM Motors
• Bronze Impeller, Peak Efficiency Pumps
• Cast Iron Bodies
• Heavy Duty Float Switches and Operating Controls
• Capacities 10,000—50,000 EDR
• Discharge Pressures 20—80 PSIG
• Standard Receiver Sizes: 10-15-30-45-75-95 gallons.

Evergreen® Series Condensate Return Pumps are designed to provide an efficient means of condensate recovery for steam heating systems and steam process applications. A float actuated switch turns the pump on and off based on the water level in the tank.

Evergreen Condensate Pumps are available in simplex and duplex packages.

Evergreen® Series Boiler Feed Pumps are designed to maintain boiler water level and provide make-up water from an outside
source. A boiler water line control turns the pump on and off when the boiler requires it. Water level in the receiver tank is maintained by using a water make-up valve activated by a reverse acting float switch. If the water in the receiver is inadequate, additional boiler feed water is automatically added to the receiver tank. Some typical applications include gravity return comfort
heating system, low pressure boilers or low pressure process equipment.

Low Operating Costs
Evergreen® Series designed with high efficiency 3450 RPM motors and peak efficiency pumps which yield lower energy costs. These pumps have long life, high temperature ceramic seals (250°) eliminating the stuffing box designed leakage of valuable condensate. The motors are mounted off the floor in a lower maintenance environment.

Overload Protection
Evergreen® Series Control Panel comes with high quality electrical controls which
provide peak overload protection, featuring across the line magnetic starters and
circuit breakers and are accurately tuned to the specific loading needs of the motors. Units with 2HP and larger motors require an electrical control panel. Smaller
HP motors can be ordered with a control panel providing the same protection
afforded the larger motors.

Oversized Rated Duty
Evergreen® Series units are designed for low NPSH® giving them the ability to
handle high temperature condensate quietly and efficiently at a much higher
then specified EDR. This assures low maintenance and long life. Duplex models
provide 100% stand-by with alternation.
