Aftermarket seal selection for Javelin pump maintenance

The LUWINT GFO is an aftermarket mechanical seal offered for Javelin pump replacement enquiries. Its compact assembly incorporates a circular mounting flange. Selection should be based on the existing seal and pump configuration, with the mounting dimensions checked before ordering.

For maintenance teams replacing a worn or leaking seal, identifying the complete assembly matters as much as matching the shaft diameter. Send us the pump nameplate and photographs of the removed seal so we can help check the replacement required.

Why Choose the GFO

• Assembly-based selection: compare the complete seal, including the mounting flange and installed working length.

• Clear identification: use LUWINT GFO as the enquiry reference when requesting a replacement or quotation.

• Local selection support: discuss your pump, liquid and operating conditions with Luwint in Sydney.

Choosing the Correct Seal

Please provide the following details:

Item	What to check
Pump identification	Full Javelin model and existing seal reference, if available
Shaft diameter	Diameter at the seal mounting position
Mounting flange	Outside diameter, fixing-hole centres and hole sizes
Seal dimensions	Installed working length and locating dimensions
Operating duty	Liquid, temperature, seal-chamber pressure and pump speed

A similar appearance or matching shaft diameter alone does not establish interchangeability. Confirm the mounting arrangement and material combination before installation.

Applications in Australia

For Javelin vertical multistage pump enquiries, relevant duties include water supply and pressure boosting, irrigation, washdown and water treatment. GFO suitability must be checked for the particular pump and service conditions.

Materials and Operating Conditions

Ask us to confirm the seal-face pairing, elastomer and metal specification for your required assembly. Material selection needs to account for the pumped liquid, cleaning chemicals and operating temperature.

Pressure, temperature and speed limits must be confirmed for the selected GFO configuration.
