Boiler feed pumps move feedwater, either fresh water or returning condensate, into steam boilers to maintain levels. Boiler feed pumps are normally centrifugal pumps and are available in either simplex or duplex styles with various size motors.
31-10-2013· Plans for a small boiler feed water pump? Nevadablue. 1,101. Steam fanatic. Nevadablue. 1,101. Post Oct 31, 2013 #1 10-31T19:18. I am setting up for my first steam engine build. I have the PM Research 3BI unmachined engine kit, their little vertical boiler kit and their unmachined dynamo kit. I would like to build some of the accessories from scratch, things like the water tank and boiler â€¦

Martin Baylis Engineering is now offering an engine driven feed pump to suite their range of marine steam engines. The pump is simply bolted onto the end of the engine bed and an eccentric fitted to the stub end of the crankshaft. It is possible for any existing engine owner to retro-fit this pump to their engine. The kit comprises of; feed pump assembly, inline filter and priming pump, 8BA bolts and â€¦
The ASME code requires that the boiler feed pump be able to put water in the boiler at the evaporation rate at a pressure which is 3% greater than the highest setting of the safety valves. If the boiler in this example is designed for 150 psig operating pressure, the safety valves could be set at 175 psig. To determine if the pump selection meets this requirement, recalculate the discharge pressure required â€¦

The Clayton Feedwater Pump is a pack-less and seal-less positive displacement type oil reservoir and diaphragm pump. It utilizes the diaphragm to isolate the feedwater in the pump column from the hydraulic oil in the crankcase. Water is drawn through the inlet check valves and discharged through the outlet check valves as the column of water is moved by the diaphragm. In modulating units, feedwater â€¦
Large industrial condensate pumps may also serve as the feedwater pump. In either case, to force the water into the boiler, the pump must generate sufficient pressure to overcome the steam pressure developed by the boiler. This is usually accomplished through the use of a centrifugal pump.
Boiler feed water pumps are commonly centrifugal pumps. To ensure a high enough head and pressure, Boiler feed Pumps have been arranged in series (multistage pumps). A feedwater pump is most often driven by an electric motor for energy efficiency. Often two steam turbine-driven (turbo pump) and two electric feedwater pumps are used.
