Hoffman pump

Hoffman Specialty Watchman Series condensate units are documented in Xylem's product literature. A Watchman Series unit is a receiver with a pump and a float switch that collects condensate from the heating returns and pumps it to the boiler.

BoilerSupplies.com lists two Hoffman families: Hoffman Domestic Condensate Units and Simplex Condensate Return Tanks. The products are the Hoffman Condensate Units in the Watchman Series and the Hoffman 9 Gallon Condensate Unit, also a Watchman Series unit. Simplex means one pump on the receiver. A replacement is picked from the nameplate of the unit it replaces.

How does a Hoffman Watchman condensate unit work?

A Hoffman Watchman condensate unit runs on its float switch. Condensate from the steam system drains into the receiver, the float rises with the level and starts the pump, and the pump sends the water on to the boiler. The pump stops once the level has dropped, and the cycle repeats as more condensate comes in.

What do heating contractors call a Hoffman condensate unit?

Condensate return tank, condensate pump and condensate receiver are the names most often used for a Hoffman condensate unit as a whole. Strictly, the receiver is the tank, the pump is bolted to it, and the float switch runs the pump. BoilerSupplies.com lists the Hoffman Watchman Series under Simplex Condensate Return Tanks and Hoffman Domestic Condensate Units.

Which nameplate details identify a Hoffman condensate unit?

The model on the nameplate of the Hoffman unit in place now identifies it. Add the receiver size and everything on the motor plate, copied out or photographed. If the nameplate is gone, photos of the whole unit and of its piping connections stand in for it.

What does simplex mean on a condensate unit?

Simplex means the unit has one pump on the receiver. That single pump handles the condensate the receiver collects, started and stopped by the float switch. BoilerSupplies.com lists the Hoffman units under the family name Simplex Condensate Return Tanks, along with Hoffman Domestic Condensate Units.
