Detailed Specification for Chemical Process Pump and Mechanical Seal

CASING

Design Features :

Construction :

SEALING SYSTEM

In and Out Sealing Options :

External flushing or lubrication as required.
Stuffing box fully machined for mechanical seal installation (initial or field conversion).

Seal Configurations :

Inside, outside, unbalanced, balanced, single, double, or tandem seals.
Tailored gland, throat bushing, throttle bushing, and flushing lines for specific sealing challenges.

Gland Design :

Fully confines stationary mating ring gasket for a robust seal.

BEARINGS

Inboard Bearing :

Pressed onto the shaft and free to float axially in the frame, handling radial loads exclusively.

Outboard Bearing :

Locked onto the shaft to manage radial and unbalanced thrust loads.

Type :

IMPELLER

Design :

Construction :

Secured with a nut and sealed with a PTFE O-ring, preventing loosening under incorrect motor rotation.
Dynamically and statically balanced for stable operation.

BEARING FRAME

Structure :

Sturdy cast-iron frame ensuring rigid bearing alignment and shaft support.
Large oil reservoir with a visible constant-level oiler.

Protection :

BASE PLATE

Fabricated from mild steel with drip-rim type construction.
Accommodates all pump sizes and standard IS/IEC motor frame sizes with nine base plate variations.

Coupling :

Spacer-type coupling facilitates back pull-out maintenance.
Standard RATHI (Lovejoy) RRS-type coupling supplied unless specified otherwise.

Shaft :

One-piece design with maximum deflection of 0.05 mm at the stuffing box face.
Ground to a precision finish (< 0.8 microns) for smooth operation.

STUFFING BOX COVER

Functionality :

Houses the stuffing box chamber and encloses the casing's back.
Allows for pre-assembled spare back pull-out assembly.

Temperature Handling :

Cooling jackets for high-temperature applications or heating high-viscosity liquids.

Design :

Packed box includes 4 packing rings, a lantern ring, and quench gland with auxiliary packing.
Split gland for easy removal and tapped openings for lantern ring connections.
