Hoffman

Hoffman Specialty is a Xylem line of steam specialties: steam traps, vents and vacuum breakers, regulators, valves, strainers, and condensate and boiler feed units. Watchman is a Hoffman Specialty series of condensate units. A Hoffman condensate unit collects the condensate coming back from a steam heating system in a receiver and pumps it back to the boiler or to the feed tank.

The Hoffman listings on BoilerSupplies.com are parts that get replaced in service. For Hoffman Watchman series condensate units, the page lists a replacement pump and motor. Seal and rebuild kits 180010, 180011, 180013, 180014 and 180015 for Hoffman and Domestic condensate pumps are listed next to it. On the trap side it is the Hoffman float and thermostatic kits, which carry the replacement internals for a Hoffman float and thermostatic trap. The Hoffman steam trap capsules, the thermostatic element for a Hoffman radiator trap, go with them. The Hoffman Model 62 vacuum breaker admits air into a coil or line on shutdown so the condensate drains. A pump or seal kit is matched to the nameplate on the unit. A trap kit or capsule goes by the model and size of the trap.

Do the Hoffman kits fit an F&T trap, a float trap or a radiator trap?

Yes, with different parts: the Hoffman float and thermostatic kit rebuilds an F&T trap, and the Hoffman steam trap capsule rebuilds a radiator trap. F&T trap and float and thermostatic trap are one trap: a float lets condensate out and a thermostatic vent lets air out; a plain float trap has no vent. Radiator trap and thermostatic trap mean the small trap built around the capsule.

What do you need from me to find the right Hoffman pump or kit?

For a pump or seal kit, the nameplate on the condensate unit and the one on the pump. Those give the unit series, pump model, horsepower, voltage and phase. For a trap kit or capsule, the model and size stamped on the trap body, and how many. A photo of the unit nameplate, or of the trap body with its markings, does the job.

Can I get the pump and motor for a Hoffman Watchman unit without the receiver?

Yes. BoilerSupplies.com lists a replacement pump and motor for Hoffman Watchman series condensate units, so where the receiver is still tight, the receiver, float switch and piping stay. A receiver rusted through at the bottom or at the inlet takes a complete unit instead. Match the pump to the nameplate on the unit, not to the plate on the old motor.

Which Hoffman seal kit fits my condensate pump?

The kit is matched to the pump model on the nameplate. BoilerSupplies.com lists five, 180010, 180011, 180013, 180014 and 180015, for Hoffman and Domestic condensate pumps. A pump that weeps at the seal while running is the usual reason to order one. Send the unit and pump nameplate details with the request.

What does the Hoffman Model 62 vacuum breaker do?

The Hoffman Model 62 vacuum breaker lets air into a coil or line when the steam shuts off, so the condensate can run out. Steam trapped in a closed coil condenses and pulls a vacuum that holds the water in. The Model 62 opens to air as that vacuum forms, and the coil drains after shutdown. Order it by the connection on the coil or line it protects.
