Cause

Corrective Measure

F.
Faulty
check valve

1. Dirt or scale is

caught in the
pumped medium
inlet check valve or
the valve is worn or
getting hung up

• The operating medium that has been supplied is

leaking from the inlet check valve, preventing the
pressure inside the trap from increasing; as a result,
the pumped medium is not discharged

Disassembly and inspection is required

2. Dirt or scale is

caught in the
pumped medium
outlet check valve
or the valve is worn
or getting hung up

• The discharged pumped medium has flowed back into

the PowerTrap, causing the interval at which the unit
operates to grow shorter and reducing its discharge
capacity

Disassembly and inspection is required

G.
Degradation
or damage
of gasket
and O-ring

1. Damage when

assembling

2. Aging degradation

• When condensate or steam leaks from the

PowerTrap, tighten the bolts with the proper torque or
replace the gasket with a new one.

• When steam leaks into the equipment (to the pumped

medium inlet side) or outlet piping, check the O-ring.
