Shandilya Mechanical Seal Support System.API Plan 53C for Mechanical Seal Support System
The Shandilya Modified Plan 53C is a constantdifferential pressure barrier fluid sealingsystem. All units comply with and exceed API682 Plan 53C requirements.
Designed per ASME Section VIII,Division LMeets requirements of the EuropeanPressure Equipment Directive 97/ 23/EC.Available with 20 liters (5 gallon) auniversal range for all seal size.Can be supplied for new pumps orretrofitted to existing pumps from anypump manufacturer.Offers a proven history in improving seallife, particularly under varying suctionpressure.Provides an excellent mechanical sealingenvironment in the most demandingprocess conditions.
Shandilya Plan 53C is a dual pressurizedsystem that eliminates the use of gas forpressurization through the use of a
. Barrier liquid is stored on theoutside of the Bellow. The seal chamber isconnected to the bottom of the Bellow Tracker.Bellow design is such that slightly higherpressure (about 1 to 2 kg/cm2) is generated atthe top of the accumulator. The top portion ofaccumulator is connected into the seal loop.A pumping ring circulates the barrier fluidthrough a loop that includes a seal cooler andother instrumentation. The leakage is detectedby change in level.This system is ideal for applications that havefluctuating pressures.

Shandilya Magnetic Level IndicatorProviding Solution to the Most Common Practical Problems
Shandilya magnetic level indicators are low-maintenance alternatives to sight glasses andother level indicators. They provide longDistance level indication while reducing leakpoints and fugitive emissions.
It is commonly used for visual level indicationof liquids, which attack glass or are hazardous,flammable, toxic, aggressive, agitated,contaminated and under high temperature &pressure i.e. for services, where glass gaugesare unsafe or over the period of time become sodirty that they are not visible.
It consists of a chamber and an internal float innon-magnetic material, compatible with theliquid. The float containing a magnetic systemrides on the liquid level and is coupled to anexternal visual indicator, which comes in twooptions. The simpler & economical designconsists of a series of bicolor flappers. WHITEon front side and contrasting RED on thereverse. These flappers rotate correspondingto float movement, thus changing their colorfrom WHITE to RED as the float rises and vice-versa when the float falls. As such the liquidlevel represented by an external RED column.
How It Works..?Magnetic Level Indicators
Liquified Gases, Lube/Crude Oil, Dye Liquor,HCL, H2SO4, Phosphoric Acid, Ammonia,Freon, Therminol, Solvent,Refrigerant, Dowtherm, Gasoline & NaOH.
Application Area
Float Chamber and Float: SS316 StainlessSteelCalibrated Scale: White Powder Coated AL/SSRotating Flappers: CeramicProcess Connection: 1/2”or 3/4” SS 316Flange
Materials of Construction
A magnetic level indicator is often used in applications where a glass sight gauge is unsafe,environmentally risky, or difficult to see. Typical shortcomings of sight glass gauges include:
High pressures, extreme temperatures, and toxic or corrosive materialsmay cause a risk of fugitive emission of dangerous substances.Some chemical materials within a process vessel or storage tank can attack the glass, causingdiscoloration of the sight gauge, thus decreasing level visibility.Liquid-liquid interfaces can be very difficult to read in a sight glass particularly if the fluids areof similar color. Clear liquids are also difficult to see in a sight glass.
Disadvantages of Glass Sight Gauge
Advantages of Shandilya's Magnetic Level Indicator:
Easy to install, no extra piping required in most applicationsVisual level indication to 100 ft (30 m)No process liquid in contact with indicator glassIdeal for high-temperature, high-pressure and corrosive applications.No moving parts, no calibration.Best fit for chamber applications and ideal for replacing older technologies.Working Temp: 200°C, Working Pressure: Upto 40Kg/cm²

How It Works..?
The Thermo Siphon system performs all thebasic functions of a buffer/barrier systemfor the operation of double seals:to pressurize the seal chamberleakage compensationbuffer/barrier fluid is circulated by thermosiphon effect or forced circulation systemto cool the sealto selectively absorb product leakage andp re ve n t d r y r unn i ng ( t an de marrangement)
Use compressed air or Nitrogen forpressurization; pressurization is monitoredby a pressure switch. The incorporated levelswitch gives a signal whenever the level ofbuffer/barrier fluid is too low.
