How to Choose Between a Mission Pump Seal and a Gorman Rupp Seal

When it comes to selecting the right mechanical seal, choosing between the Mission Pump Seal and the Gorman Rupp Seal depends largely on your application, fluid type, and operating conditions. Here are the key factors to consider:


1. Application Type

·        Mission Pump Seal → Designed for heavy-duty applications such as oil & gas drilling, mining, and slurry pumping where fluids are abrasive and corrosive.

·        Gorman Rupp Seal → Best for municipal, wastewater, irrigation, and general industrial water pumping, where fluids are less abrasive.

Choose Mission if you’re handling slurries, drilling mud, or abrasive media.
 Choose Gorman-Rupp if you’re moving water, wastewater, or light industrial fluids.


2. Operating Conditions

·        Mission Seal → Handles higher pressure and temperature ranges, often up to 6 MPa and 125 °C, built with rugged materials like tungsten carbide and silicon carbide.

·        Gorman Rupp Seal → Works under moderate conditions, with seals commonly made from carbon/ceramic combinations and elastomers like Viton® or Buna.

Choose Mission for extreme pressure/temperature environments.
 Choose Gorman-Rupp for standard pumping conditions.


3. Material Compatibility

·        Mission Pump Seal → Offered in heavy-duty materials to resist erosion and corrosion, ideal for aggressive fluids.

·        Gorman Rupp Seal → More cost-effective materials, sufficient for clean or lightly contaminated fluids.


4. Maintenance & Cost

·        Mission Seal → Longer service life in abrasive conditions but higher upfront cost. Replacement cartridges available for easier maintenance.

·        Gorman Rupp Seal → More economical and easy to replace, suited for municipal or industrial operations with budget considerations.


5. Decision Guide

·        Go with Mission Pump Seal if:

          o   You are in oil & gas, mining, or slurry handling.

          o   You require high durability against abrasive media.

          o   You need seals for high-pressure, high-temperature systems.

·        Go with Gorman Rupp Seal if:

          o   You’re handling water, wastewater, or non-abrasive fluids.

          o   You need a cost-effective, easy-to-maintain solution.

          o   Your application is municipal, agricultural, or general-purpose pumping.



How to Install a Mission Pump Seal or Gorman Rupp Seal

Proper installation is key to ensuring seal life and pump efficiency. Follow these general steps:


1.     Preparation

o   Shut down the pump and isolate it from the system.

o   Drain fluid and clean the stuffing box/seal chamber thoroughly.

o   Inspect the pump shaft/sleeve for wear, scoring, or corrosion.


2.     Seal Inspection

o   Verify that the seal faces, elastomers, and hardware are clean and free of damage.

o   Check that you have the correct seal size and materials for your application.


3.     Seal Installation

o   Apply a thin film of lubricant (compatible with elastomers) to ease installation.

o   Carefully place the stationary seal seat in the gland or housing.

o   Slide the rotating unit onto the shaft without forcing it—avoid scratching seal faces.

o   Align the seal faces and tighten gland bolts evenly to manufacturer torque specs.


4.     Final Checks

o   Rotate the shaft by hand to confirm smooth operation.

o   Restore system pressure and prime the pump.

o   Check for leaks during startup at low speed/pressure before resuming full operation.
