Complete Guide to JWI Filter Press Parts
If you are running a JWI filter press, you already know that keeping it operating efficiently comes down to one thing: having the right replacement parts, in stock, and ready to ins
Over time, every filter press will require maintenance — cloths wear out, gaskets flatten, center feed pipes develop cracks, and hydraulic systems lose pressure.
This complete guide will walk you through every major JWI filter press part, what it does, when it fails, and how to replace it quickly to minimize downtime.
What Are the Main JWI Filter Press Parts?
A JWI filter press is made up of several key components that all work together to separate solids from liquid:
Each of these parts plays a critical role in performance — and when one fails, the entire system suffers.
Filter press cloths are responsible for capturing solids while allowing liquid to pass through.
Common Problems:
- Blinding (plugged cloths)
- Slow cycle times
- Wet filter cake
- Poor filtrate clarity
When to Replace:
- Cycle times increase significantly
- Solids begin passing through
- Filter Press Cloths no longer release cake properly
When filtration cycles become longer or the filter cake remains wet, it is often due to blinded or worn JWI filter press cloths that are no longer allowing proper liquid flow.

Filter plates form the chambers where solids accumulate during filtration.
Common Issues:
- Warped or cracked plates
- Worn sealing surfaces
- Misalignment
Key Insight:
If plates are damaged, no amount of new cloths or gasketing will fix leaks.

JWI Filter Press Plates
Gasketing is one of the most critical and most overlooked components of a filter press.
It creates the seal between plates to prevent slurry from leaking.
Common Problems:
- Leaks between plates
- Dripping during filtration
- Flattened or brittle gasket material
Important Note:
Gasketing is often referred to as:
- Filter press gasket
- O-ring cord
If your filter press is leaking between plates, the most common cause is worn or flattened JWI filter press gasketing (O-ring cord), which should be replaced to restore proper sealing and prevent slurry bypass.
All refer to the same sealing component.

The center feed pipe delivers slurry into the filter press.
Common Failure:
- Hairline cracks in the pipe
What Happens:
Instead of slurry entering the chambers, water finds the easiest path and leaks:
- Between the head plate and frame
- Around the outside lock nut
Critical Warning:
If your press is leaking at the head or feed connection, the center feed pipe likely needs to be replaced immediately.
Leaks near the head plate or around the feed connection are frequently caused by a cracked JWI center feed pipe assembly, allowing liquid to escape instead of entering the filter chambers.

The hydraulic system is responsible for closing the press and maintaining pressure.
Includes:
- Hydraulic pump
- Power unit
- Pressure controls
Common Problems:
- Low closing pressure
- Leaks in hydraulic lines
- Pump failure
Result:
- Leaking plates
- Poor cake formation
- Unsafe operation

JWI Hydraulic Systems
The hydraulic cylinder physically closes the press and holds pressure during operation.
Common Issues:
- Internal seal failure
- Loss of pressure over time
- Oil leaks
Important Note:
Many older JWI cylinders do not have identifiable rebuild kits, making replacement the best option.

Most Common JWI Filter Press Problems (And the Cause)
Problem: Leaking Between Plates
Cause:
Problem: Leak at Head Plate or Feed Pipe
Cause:
Problem: Wet Filter Cake
Cause:
- Blinded cloths
- Low pressure
- Short cycle times
Problem: Slow Cycle Times
Cause:
- Plugged cloths
- Incorrect feed rate
Why Stocking JWI Filter Press Parts Matters
Downtime is expensive.
Waiting weeks for parts can shut down production and cost far more than the part itself.
That’s why the best solution is working with a supplier that offers:
- In-stock inventory
- Multiple plate sizes available
- Fast shipping
- Experienced technical support
Replacement Parts for Older JWI Filter Presses
Many older JWI filter presses are still in operation today — but finding parts can be difficult.
In many cases:
- Original manufacturers no longer support the equipment
- Part numbers are missing or outdated
- Components are no longer standardized
The solution is working with a supplier that can:
- Match existing parts
- Provide upgraded replacements
- Supply complete assemblies
Final Thoughts
A JWI filter press is a reliable and proven piece of equipment — but like any machine, it requires proper maintenance and timely replacement of wear parts.
By understanding each component and recognizing early signs of failure, you can:
- Prevent costly downtime
- Improve filtration performance
- Extend the life of your equipment
