Typical Applications

Used for general condensate return or for boiler feed applications.

Available in Simplex or Duplex configurations with several different receiver sizes available.

How It Works

For Condensate Return Applications:

The float, which is connected to the switch assembly, rises when condensate enters the receiver tank. When the float rises above its set point, it energizes the motor on the pump. Once started, the pump will continue to run until the water level drops below the bottom position of the float switch.There it will de-energize the motor to shut off the pump. This cycle repeats as condensate begins to fill the receiver tank. On duplex systems the float switch is replaced with a Mechanical Alternator-Switch connected to a float. The Mechanical Alternator cycles use between the two pumps, allowing only one pump to run at a time under normal conditions. If the condensate reaches a high water level, both pumps will be activated.

For Boiler Feed Applications:

For Boiler Feed units, the operation of the pump is controlled by the water level control device which is part of the boiler control package. When the boiler requires water, the pump switches on pumping water from the receiver into the boiler.

On Duplex boiler feed units, an Electrical Alternator is used to activate one pump at a time in alternating fashion. The receiver tank also contains an internal make-up water valve actuated by a stainless steel float. This is used if the amount of condensate being returned to the receiver tank is inadequate.

Sample Specifications

Pump(s) shall be of the centrifugal type with 2-piece closed bronze impeller, cast iron housing and stainless steel motor shaft.

A flat perforated brass strainer shall be provided in the inlet of the pump.

Installation

Place on an elevated, level and substantial foundation in a clean, dry and accessible area. Locate receiver tank inlet below lowest point of the condensate return lines.

Ordering Guidelines:

1) Decide on appropriate Receiver tank material for the application; W4100-Series with Steel Receiver tanks, W4200-Series with Cast Iron Receiver tanks or W4300 with Stainless Steel Receiver tanks.

2) Based on the particular application the model selection charts are separated on adjoining pages into either Boiler Feed or Condensate Return units. The proper pump model/size in GPM (gallons per minute) to suit the application and recommended receiver size for a Boiler Feed application is based on boiler size measured in Boiler Horsepower. The proper pump model size in GPM and recommended receiver size for a Condensate Return application is based on the Effective Direct Radiation (EDR) in square feet of the heating surfaces throughout the facility that the pump is expected to handle.

3) Select a pump discharge pressure that will exceed system back pressure, friction loss in piping and pressure in the boiler (in the case of a boiler feed pump). Selecting a pump with a significantly higher discharge pressure than required can cause pump to cavitate.

4) Decide if a Simplex (Single pump) unit is adequate or a Duplex (two pump) unit would be more appropriate in terms of system reliability and redundancy in the event of a pump failure.

5) Select Motor Phase and Voltage (reference chart). For smaller units under 11/2 hp Single phase motors may be desirable because of ease of installation. For units in excess of 11/2 hp, the more efficient and robust 3-phase motors are recommended.

Example Model Code: W4142JD-3P230 Duplex Condensate Return Pump, 3 GPM flow rate & 40 PSI discharge (Pump Unit) pressure & 15 gallon receiver, 1hp, 230 VAC, 60Hz, 3-Phase motor.

Example Model Code: MECH-ALT-N1 Note: Since a Duplex pump was chosen, a Mechanical Alternator must be purchased (Mechanical Alternator) separately to replace the standard Float Switch.

1/3 thru 5 Horsepower CPN12-P1-S CPN12-P1-D Over 5 Horsepower CPN12-P2-S CPN12-P2-D

Purchasing the optional motor control panel is a convenient and simple method of hooking up your pump.

Example Model Codes: 1) CPN12-P1-S (Control Panel, NEMA 12, 1/3 thru 5 hp, Simplex, no options)

2) CPN12-P1-S-UL (Control Panel, NEMA 12, 1/3 thru 5 hp, Simplex with UL Certification)

3) CPN12-P2-D-E (Control Panel, NEMA 12, over 5 Hp, Duplex, with Electric Alternator)

For Simplex units, the control panel would include a single motor starter with a single HOA (HAND-OFF-AUTOMATIC) selector switch to turn the pump on manually to verify functionality; or, to set in automatic mode along with a single Motor Circuit Protector switch to shut power off to the pump.

For Duplex systems, the control panel would include two motor starters with two HOA (HAND-OFF-AUTOMATIC) selector switches to turn either of the two pumps on manually to verify functionality, or to set in automatic mode along with two separate Motor Circuit Protector switches to shut power off to either of the two pumps.

An Electric Alternator option can be used to replace the standard Mechanical Alternator; this option uses electronic logic as opposed to a mechanical device to cycle operation between the two pumps. If an Electrical Alternator is chosen, the Mechanical Alternator is replaced with a 2-level float switch (suffix code E).

Other Options, such as Pilot Light indicating when the pump is running or High Level Alarm Horn & Light indicating a flood system condition, can be added.

Control Panel Options Pilot Light Indicates when a pump is running;

Simplex - One light; Duplex - Two Lights.
