After a few minutes of steady-state flow, we shut down pump No. 2. The amps on pump motor No. 1 increased from 46 to 73, about normal for a one-pump operation at 70% boiler load. Next, we switched to pump No. 2 and experienced similar results. Finally, opening the minimum flow line on pump No. 2 increased motor load to 86 amps.
Pump Casing Inspection for Welded Components. Nozzles usually connected to the pump casing by the welding process. In our example the inspection class is III, so the API 610 requires visual inspection plus 100% MT or PT plus 100% RT for welded connections. The acceptance criteria for welding is completely different.
Boiler circulation problem I am experiencing a problem with my tenant's boiler. He complained of no heat, suggesting the t-stat was not working. I tried it, the boiler would not fire. (It is an old Weil CG-3, gas fired, from 1978.) Without looking further, I replaced the old t-stat. Well, the boiler fired, came up to temp, and shut down.

Oct 16, 2013 · Before the introduction of the low-flow/high-head multi-stage centrifugal type pump, turbine type pumps were used almost exclusively for on/off boiler feed service for steam boilers. The turbine pump impeller was designed with very close tolerances within the pump.
This pump is primarily made up of an outer Pump casing or housing, Impeller, Mechanical Seals, Pump Shaft & Bearings and Motor. The pump casing is the major stationary component of the pump and provides two major functions: Converts velocity head from the impeller into pressure head, and guides the flow to the discharge connection.
