[b]CONDENSATE RECOVERY USING PUMP-TRAPS[/b]
(OP)
Can anybody enlighten me on the significance of using a pumptrap for our pasteurizer and bottle washer of beer paroduction? I am planning to install a pumptrap to be able to efficiently recover the condensate. Pasteurizer uses 1500 kg/hr steam while the bottle washer uses 3000 kg/hr steam on running load.

If this is not the case, the pump (or pump/trap combination) will allow the process to work with zero back pressure and also provide additional pressure to push the condensate through the piping. This is especially usefull when you have low steam pressures or a modulating control valve on the steam inlet to the equipment.

When the steam has condensed, you obviously need to remove it. A steam trap would normally do this, but traps only work well if the condensate can fall back to the boiler feed tank by gravity (ie no back pressure)
Where gravity condensate recovery is not available, then a pumping trap can be used.
A pumping trap is a steam (or compressed air) operated pump. A set of interlocked valves allow the condensate to enter. Once the chest has filled with water, the inlet closes, the outlet opens and steam at high pressure (from your steam mains) forces out the condensate. This is pumped back to where you want it (i.e. to the boiler feed tank, or to waste or wherever you want it.
Pumping traps are mega bucks....2 to 3£K or more as opposed to a simple float trap at £200 say

I hope I would be able to solve this condensate recovery problem. Thanks guys.

Watch the sizing. I know people tend to oversize equipment to be on the safe side, but this equipment will work poorly if it is not sized correctly.
