It is typically used with pressurised dual (double) seals at a pressure greater than the box pressure.

Min. Order: 40 Rolls

Often this principle results in an excessive cooling load requirement, in which case a plan 23 is recommended/selected.

Min. Order: 480 Rolls

It is identical, but uses a strainer to filter the pumped product prior to system and seal-chamber entry.

Please refer to the plan 21. It is identical, but uses a cyclone separator to filter the pumped product prior to system and seal

Pumped product is re-circulated/injected from pump discharge through a cyclone separator

A plan 53A is a pressurised piping system with an external reservoir that contains a clean barrier fluid.

The laser-welded finned tubes are manufactured by helically winding strip onto tubes.

If a pumping ring is not available or if it would offer insufficient flow, a forced seal circulation pump can be considered.

A plan 53C is a pressurised piping system with an external reservoir that contains a limited amount of fully de-aerated clean ba

It is typically used with non-pressurised dual (tandem) seals under low or atmospheric pressure conditions.

It is also seen with dual seals to protect the inner seal from detrimental effects the pumped product may have.
