Pumps | Seal FAQs
Estimating the Pressure in Pump Seal Chambers. The pressure in the pump stuffing box must be known before the proper seal and flush system can be selected. For some pumps, the stuffing box pressure is the same as the pump suction pressure; for others, it may be near discharge pressure.

The seal-chamber section also adds HP load to the motor. It is usually a low value and significant only on lower-HP applications. Because each style of seal-chamber section has its own characteristics, the manufacturer should be consulted for these values.

Seal Chamber Pressure - an overview | ScienceDirect Topics
3.1 Interpretation of seal chamber pressure. A key issue is whether the specifying engineer bases the barrier fluid pressure calculation on ‘normal’ seal chamber pressure, or the ‘maximum’ seal chamber pressure that can occur due to high pump suction pressure in a plant upset condition. There is an increasing trend to adopt the maximum ...

Seal chamber pressure can vary based on pump design. The follow-ing equations are based on closed throat design seal chambers. Pump designs include wear rings and balance holes in the impeller to reduce thrust load on the bearings. The seal chamber pressure is a function

between the seal chamber pressure and the product vapor pressure. For NGL products, this margin should be 50 psi (3.44 bar) mini-mum. Since the seal chambers will operate at or near the suction pressure, a Plan 11 flush, piped from the discharge volute (single stage pump) or from an intermediate stage discharge (multistage pump), is suggested.

Importance of barrier fluid pressure in double seal
This article gives you an idea about the difference between buffer plan (unpressurised) and Barrier Plan (pressurised). It explains how barrier fluid pressure helps to support double (dual) mechanical seals in a pressurised plan and increases MTBF (Mean Time Between Failure) of seal. The use of dual mechanical seals in industries has increased due to […]

Seals offer better safety when Equipment damaged and destroyed from leakage. Seals offer better safety when sealing potentially hazardous materials. Greater clearance = more leakage and less wearleakage and less wear. Typical seal face film thickness isTypical seal face film thickness is 10-50 -in (micro-inches).

Seal chamber section. The component located below the lowest pump section and directly above the motor, in a standard electrical submersible pump (ESP) configuration, is the seal-chamber section. API RP 11S7 gives a detailed description of the design and functioning of typical seal-chamber sections.

How do seal chamber pressures typically differ between
NDE has a seal chamber pressure equal to the discharge pressure. In case of vertical pumps typically for VS4 and VS5 type of pumps the seal chamber is dry and hence is subjected only to 1atm. However for VS1 or VS6 type of pumps has a seal chamber pressure equal to the pressure of discharge pressure.

PTM is the difference between the process temperature in the seal chamber and the saturation temperature of the process liquid at the seal chamber pressure. As an example, the API 682/ISO 21049 qualification tests on propane are at 32 C (90 F) and an absolute pressure of 1.8 MPa (18 bar) (261 psia).
